  6. Hi, I have a details screen where visitors to the website can leave their contact info. I have some javascript rules to validate some of the fields when the visitor is filling them out so they cannot leave certain fields empty. I have an email field where aswell as stopping the visitor leaving the field blank i want a validation check so it looks for the presence of "@" and a "." within the field. But I am having trouble getting this implemented. Currently my code for the blank checks looks like this (with the email field in the last block) :- </script><script language="javascript" type="text/javascript">function validate_form ( ){valid = true; if (document.networkOpportunity.contactName.value == "") { alert ( "Please enter the name of the contact for the opportunity." ); document.networkOpportunity.contactName.focus(); = "#d7edf8"; valid = false; } else if (document.networkOpportunity.companyName.value == "") { alert ( "Please enter the company name that the opportunity is for." ); = "#FFFFFF"; document.networkOpportunity.companyName.focus(); = "#d7edf8"; valid = false; } else if (document.networkOpportunity.serviceRequired.value == "") { alert ( "Please enter the details of the service you require." ); = "#FFFFFF"; document.networkOpportunity.serviceRequired.focus(); = "#d7edf8"; valid = false; } else if (document.networkOpportunity.contactEmail.value == "") { alert ( "Please enter the email we can contact you on." ); = "#FFFFFF"; document.networkOpportunity.contactEmail.focus(); = "#d7edf8"; valid = false; } Any help with how to add the extra validation on the contactEmail field to look for "@" and "." will be greatly appreciated.
  7. I have modified this script to include a call-to-action button when a video ends. What I'm trying to do is get the button to work on mouse rollover and click. The button works and comes up after the video ends but I can't seem to place the attributes in a logical place to get them to work. It's a little advanced for me so I'm hoping that someone can do this and explain what they did so I can learn. I've spent hours on this! LOL Here's the whole script... <div id="player"></div> <script type="text/javascript"> jwplayer("player").setup({ playlist: [{ image: "", sources: [{ file: " Assessment Intro.m4v" },{ file: " Assessment Intro.webm" }] }], width: 853, height: 480, stretching: "fill" }); jwplayer().onComplete(function() { var el = document.createElement("div"); var el2 = document.createElement("div"); var el3 = document.createElement("div"); var el4 = document.createElement("div"); var txt = document.createElement('a'); if (jwplayer().getRenderingMode() == "html5"){ var theBody = document.getElementById(; } else { var theBody = document.getElementById("_wrapper"); } var playerWidthPX2 =; var playerWidthPX = parseFloat(playerWidthPX2); var playerHeightPX2 =; var playerHeightPX = parseFloat(playerHeightPX2); el3.setAttribute('id', 'bg'); = playerHeightPX + "px"; = playerWidthPX2; = "#ffffff"; = "0.70"; = "absolute";"url('background.png')"; el.setAttribute('src', 'background.png'); if (jwplayer().getRenderingMode() == "html5"){ } else { = playerHeightPX-playerHeightPX+"px"; } = "999"; el3.width = playerWidthPX; el3.height = playerHeightPX; el2.setAttribute('id', 'bg2'); = playerHeightPX + "px"; = playerWidthPX2; = "absolute"; = "999"; el2.width = playerWidthPX; el2.height = playerHeightPX; theBody.appendChild(el3); theBody.appendChild(el2); = "center"; = "center"; = ((playerHeightPX*3)/6) -"40" + "px"; el.setAttribute('id', 'hyperlink'); = "30px"; = "30px"; el2.width = "30"; el2.height = "30"; = "relative"; el.setAttribute('frameBorder', '0'); = "11px"; = "202px"; = "center"; = "-16px"; = "8px"; el4.setAttribute('id', 'replay'); = "20px"; = "20px"; el4.height = "20"; el4.width = "20"; = "absolute"; = "-" + playerHeightPX/2 + "px"; = "50px"; = playerWidthPX/2 + "px"; = "50px";"url('replay.png')"; el4.setAttribute('src', 'replay.png'); el2.appendChild(txt); txt.outerHTML = '<a href="" onMouseOver="return changeImage()" onMouseOut= "return changeImageBack()" onMouseDown="return handleMDown()" onMouseUp="return handleMUp()"><img name="jsbutton" src="" width="402" height="127" border="0" alt="javascript button"></a>'; el2.appendChild(el); el2.appendChild(el4);"url('hyperlink.png')"; el.setAttribute('src', 'hyperlink.png'); = "pointer"; = "table"; = "table"; = "table"; = "table"; = "table"; el.onmouseup = function(){""); } = "pointer"; el4.onmouseup = function(){ = "none"; = "none"; = "none"; = "none"; = "none"; jwplayer().play(); } }); </script> Here is a complete script of the button that works... <a href="" onMouseOver="return changeImage()" onMouseOut= "return changeImageBack()" onMouseDown="return handleMDown()" onMouseUp="return handleMUp()" ><img name="jsbutton" src="" width="402" height="127" border="0" alt="javascript button"></a> <script language="JavaScript"> upImage = new Image(); upImage.src = ""; downImage = new Image(); downImage.src = "" normalImage = new Image(); normalImage.src = ""; function changeImage() { document.images["jsbutton"].src= upImage.src; return true; } function changeImageBack() { document.images["jsbutton"].src = normalImage.src; return true; } function handleMDown() { document.images["jsbutton"].src = downImage.src; return true; } function handleMUp() { changeImage(); return true; } </script> I'm trying to put them together!

  9. Hey there, i have a Java MVC Web Application that uses the Spring-Library for the Backend and then JSP files for the frontend. Now, in various JSP files i am using Ajax to have some smooth design when needed. This whole application is running on an Apache Tomcat Server. I have to admit that i am still very new in the whole Web-Development thing, so bare with me.Following problem: In the current state, i feel like the tomcat server is automatically handeling the Sesions, including session-timeouts. So, i can specify the time when a session is supposed to count as timed out and everything, the server recognized this correctly and whenever i try to request something with a timedout session the server automatically logs me out and brings me back to the login page. I havent found any implementation of such behavior in the source-code, hence i assume that this is somehow implemented by some standard tomcat routine. The problem with this behavior is, that the server sends a 302 redirect message specifying the login-Page as Location in the response-header. While this works fine for normal requests it is bad for ajax-requests, as these cannot handle 302 codes. The browser catches that one and the ajax-call has no chance to ever process the reply. I am experiencing weird cookie problems and i supsect that this might be the cause of the problem. Now, it shouldnt be hard to check whether or not a request is done by an ajax-call or not. However, i have no clue WHERE i should do so. Edit: I know that there is a way of specifying Filters and there is a way of setting up a listner that gets informed about Session-creations and destructions. However, none of these suit what i want. I need to cut in at a level that allows me to process a request, see if it is an ajax-call and then see if the session used along it is timed out and then i need to be able to decide how i respond to it. Using a filter i am BEHIND that step. I get controll when stuff regarding session timeout has happened already. Using a Session-Lifetime listner i do not have any infromation about the request. I cannot respond to anyone because i have no information about any Requests. How could i go about implementing my custom session-timeout behavior without interfering with the servers implementation?Am i even right assuming that the server automatically handles these cases? It feels kind of odd that the server knows that it has to logg someone out and also knows what to redirect to. Thanks in advance If there are any questions regarding mine ... ask away
  10. Hello so I made an array and it works fine when you refresh the page the image changes but at lower screen resolutions the image cuts of the edge. With my basic code it worked fine I was wondering what I was doing wrong. This was my old code which was just one image and at lower resolutions it would still fit on the screen <center><img src="my image url" width=47%> </center> But when I use my array it cuts of I want to make the image center and just put width=47% like the top code but not sure where to put it <script language="JavaScript"><!--function random_imglink(){var myimages=new Array()myimages[1]="my image url"myimages[2]="my image url"myimages[3]="my image url"myimages[4]="my image url"myimages[5]="my image url"myimages[6]="my image url"var ry=Math.floor(Math.random()*myimages.length)if (ry==0)ry=1document.write('<img src="'+myimages[ry]+'" width=47%')}random_imglink()//--></script> If you could help me it would be much appreciated

  13. I am somewhat new to javascripting and am working on a page load for specific content. My interal client has requested an alert to occur when someone navigates to the home page. I added a popup alert to my webpage with the following javascripting: function loadImage() { alert("This reference material contains confidential information and is not to be shared with team members who do not service private exchange business.");} <body onload="loadImage()"> It's pretty simple, but my business partner has now asked that instead of it presenting on every load, they wish it to only present on the intial load of the webpage. I have searched w3schools, but can't seem to find any expressions that will handle this type of request.

  15. Hi, First, i need to tell you that i am not experienced in CSS or coding myself but i have fairly good overall technical knowledge. I'm in need of a very simple full screen slideshow consisting of 4 images. I found a CSS3/javascript for this here: I've tried to tweak it a bit to suite my needs. However, its not really optimal. I would like to change it so it doesnt fade between the images, a fast cut would be better. Also the original was for 6 images but i tried to change it to a 4 image slideshow but im not sure i did it correctly. Can someone help me with these two issues? thanks guys! the HTML looks like this: <!DOCTYPE html><!--[if lt IE 7 ]> <html class="ie ie6 no-js" lang="en"> <![endif]--><!--[if IE 7 ]> <html class="ie ie7 no-js" lang="en"> <![endif]--><!--[if IE 8 ]> <html class="ie ie8 no-js" lang="en"> <![endif]--><!--[if IE 9 ]> <html class="ie ie9 no-js" lang="en"> <![endif]--><!--[if gt IE 9]><!--><html class="no-js" lang="en"><!--<![endif]--> <head> <meta charset="UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <title>Claires slideshow Screen 1</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta name="description" content="Fullscreen Background Image Slideshow with CSS3 - A Css-only fullscreen background image slideshow" /> <meta name="keywords" content="css3, css-only, fullscreen, background, slideshow, images, content" /> <link rel="shortcut icon" href="../favicon.ico"> <link rel="stylesheet" type="text/css" href="css/demo.css" /> <link rel="stylesheet" type="text/css" href="css/style1.css" /> <script type="text/javascript" src="js/modernizr.custom.86080.js"></script> </head> <body id="page"> <ul class="cb-slideshow"> <li><span>Image 01</span><div></div></li> <li><span>Image 02</span><div></div></li> <li><span>Image 03</span></div></li> <li><span>Image 04</span><div></div></li> </ul> </body></html> and the CSS looks like this: .cb-slideshow,.cb-slideshow:after { position: fixed; width: 100%; height: 100%; top: 0px; left: 0px; z-index: 0; }.cb-slideshow li span { width: 100%; height: 100%; position: absolute; top: 0px; left: 0px; color: transparent; background-size: cover; background-position: 50% 50%; background-repeat: none; opacity: 0; z-index: 0; -webkit-backface-visibility: hidden; -webkit-animation: imageAnimation 72s linear infinite 0s; -moz-animation: imageAnimation 72s linear infinite 0s; -o-animation: imageAnimation 72s linear infinite 0s; -ms-animation: imageAnimation 72s linear infinite 0s; animation: imageAnimation 72s linear infinite 0s; }.cb-slideshow li:nth-child(1) span { background-image: url(../images/1.jpg) }.cb-slideshow li:nth-child(2) span { background-image: url(../images/2.jpg); -webkit-animation-delay: 18s; -moz-animation-delay: 18s; -o-animation-delay: 18s; -ms-animation-delay: 18s; animation-delay: 18s; }.cb-slideshow li:nth-child(3) span { background-image: url(../images/3.jpg); -webkit-animation-delay: 36s; -moz-animation-delay: 36s; -o-animation-delay: 36s; -ms-animation-delay: 36s; animation-delay: 36s; }.cb-slideshow li:nth-child(4) span { background-image: url(../images/4.jpg); -webkit-animation-delay: 54s; -moz-animation-delay: 54s; -o-animation-delay: 54s; -ms-animation-delay: 54s; animation-delay: 54s; }/* Animation for the slideshow images */@-webkit-keyframes imageAnimation { 0% { opacity: 0 } 1% { opacity: 1 } 2% { opacity: 1 } 25% { opacity: 1 } 26% { opacity: 0 } 27% { opacity: 0 } 100% { opacity: 0 }}@-moz-keyframes imageAnimation { 0% { opacity: 0 } 1% { opacity: 1 } 2% { opacity: 1 } 25% { opacity: 1 } 26% { opacity: 0 } 27% { opacity: 0 } 100% { opacity: 0 }}@-o-keyframes imageAnimation { 0% { opacity: 0 } 1% { opacity: 1 } 2% { opacity: 1 } 25% { opacity: 1 } 26% { opacity: 0 } 27% { opacity: 0 } 100% { opacity: 0 }}@-ms-keyframes imageAnimation { 0% { opacity: 0 } 1% { opacity: 1 } 2% { opacity: 1 } 25% { opacity: 1 } 26% { opacity: 0 } 27% { opacity: 0 } 100% { opacity: 0 }}@keyframes imageAnimation { 0% { opacity: 0 } 1% { opacity: 1 } 2% { opacity: 1 } 25% { opacity: 1 } 26% { opacity: 0 } 27% { opacity: 0 } 100% { opacity: 0 }} /Joel
  16. Hello internet, I was not sure if I should put this in JAVASCRIPT or php – in the end the form gets submitted so I decided to put this in the PHP forum. Here is my dilemma – I have several JAVASCRIPT checks to make sure people fill out their name, phone number, feedback content, and have a valid email address. On occasion it seems like people are getting around that JAVASCRIPT just to prove a point. Blank forms are being submitted. What can I do to prevent this?

  20. I am trying to learn any programming language and I have looked into several sites including Oracle and I must say everything I've tried to learn hasn't stayed in well. I personally love the layout and the design as well as the ability to try it yourself on W3Schools' site. I Understand that W3Schools was made to teach everything you need to know to create a webpage, or to be used as a reference to commands in a language used in making a webpage, but I and many others would greatly benefit if W3Schools could adopt a programming section. I am starting to learn Java and as for right now I only request Java, But I would like to see all commonly used programming language. I used W3Schools to learn HTML, CSS, and a little bit of JavaScript, It took me a little under 7 hours to learn a large portion of HMTL and CSS. I just love W3Schools' Website and Teaching ways. I would love to learn every language possible here, I find this the best way to learn Computer languages.

  24. This should be easier than I am trying so maybe I am not thinking about it correctly. I need to insert a "click here" button on a webpage that when clicked would open a 2nd page beside the first. It would not Close the first page as they both need to be open. As a for instance, the 2nd page might contain detailed instructions on how to do something on the first page but not everyone would need them So I created webpage inside a subfolder of the first page. (It is a VERY simple site that really only has varying views of the first page. Only one Index.php) The second page is also a stand alone. If you typed in the full path to enter that subfolder it has its own index.php and would open as a standalone page. I know I have seen a method of setting the page width (or I thought I had) to 50% so that two pages could co-exist at the same time for the viewer it would look like page 1 and page 2 of a book separated by the book spine, Optionally, it could be done after the fact if the 2nd page opened in a second window instead of a tab,. There may be other ways I have not considered but any help would be appreciated. Thanks If I can crate a sample screenshot view I will come back and attach it. right now I have maybe 10 tabs open. and if I switch between then I cannot see the tab I was on when I leave it. but it it were 10 separate instances of IE I could open both at the same time and resize easily with the win+left or right arrow key. doing that in tabs wont work to get two pages open at once.
  25. I'm trying to make a XMLHttpRequest from a JavaScript page to a Java Servlet.I found out lots of problem because it's first time that I do this. The main problem it's that the servlet doesn't work!It give me this error: HTTP Status 500 - Servlet execution threw an exception type: Exception report message: Servlet execution threw an exception description: The server encountered an internal error that prevented it from fulfilling this request. exception: javax.servlet.ServletException: Servlet execution threw an exceptionroot cause java.lang.NoClassDefFoundError: com/google/appengine/api/channel/ChannelServiceFactoryProvaServer.Server.doPost( cause java.lang.ClassNotFoundException: note The full stack trace of the root cause is available in the Apache Tomcat/7.0.33 logs. This is the Java Servlet code: package ProvaServer; import java.lang.Object;import;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import*;import; @WebServlet(description = "prova", urlPatterns = { "/provaFinale" })public class Server extends HttpServlet { private static final long serialVersionUID = 1L; public Server() { super(); // TODO Auto-generated constructor stub } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String userId = request.getParameter("idUser"); ChannelService channelService = ChannelServiceFactory.getChannelService(); //the problem is here! String token = channelService.createChannel(userId); System.out.println("IdUser:" + userId); System.out.println("Token:" + token); String url="mona.html?user="+userId+"&token="+token; response.sendRedirect(url); } @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {}} and this is the web.xml servlet mapping file: <?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="" xmlns="" xmlns:web="" xsi:schemaLocation="" version="3.0"> <display-name>Server</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> <servlet> <servlet-name>ServerServlet</servlet-name> <servlet-class>ProvaServer.Server</servlet-class> </servlet> <servlet-mapping> <servlet-name>ServerServlet</servlet-name> <url-pattern>/provaFinale</url-pattern> </servlet-mapping></web-app> The problem come out when servlet try to run this code: ChannelService channelService = ChannelServiceFactory.getChannelService() but i can't understand what is the error.Could someone help me to understand? Thanks for the attention!
