  1. ACKNOWLEDGMENT and RESULTS: Let me begin by announcing my success in having merged Matomo and wordcount2.js into a dynamically loading word cloud that reflects visitor use of Grammar Captive's local search engines. It is a little slow in loading, but unfortunately everything related to Matomo is slow at this point -- this, despite my recent server upgrade that has sped everything up. If you would like to see the result, simply click on the menu option Word Cloud under Visitor Profile in the navigation bar on the Grammar Captive mainpage. And, now back to Javascript. Thank you everyo
  2. DILEMMA: Using Javascript with Matomo to track events is somewhat elusive. This is because the Javascript that communicates with the Matomo application is generally placed on a visitor-friendly, visible HTML document, while the events that one wishes to track are often triggered by Javascript after the page has loaded. QUESTION: In light of the above,. when Javascript is called after a page has loaded is the Javascript that loaded with the page called again? Or, is it only the Javascript that was called after the page has been loaded? Roddy
  3. BACKGROUND: I would like to insert a jQuery UI widget into my code. In order to make the widget work, however, it appears to require a more recent version of jQuery. Should I implement the widget, the HTML in which it resides, the controlling Javascript including the new version of jQuery, as well as the CSS would all be called dynamically when the widget is inserted. My concern is that the new inserted version of jQuery might interfere with the rest of the page not included in the insert. QUESTION: Do I have reason to be concerned? Please explain your answer.
  4. sir/madam, I try to making a project that can "Allow only 3 items to add from one list to another" here IS MY CODE:- HTML CODE:- <!DOCTYPE html> <html> <head> <title>jQuery click UI</title> <meta charset="UTF-8"> <link rel="stylesheet" href="style-click.css"> <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js"></script>
  5. GENERAL QUESTION: Can variables created outside of a function be used within a function without having to read them first as arguments of the function? If so, can a function created within a function use a variable created outside of both functions? CODE var dataString = 'search_input=' + search_letter_input; $.ajax({ type: "POST", url: './...', data: dataString, dataType: 'JSON', statusCode: { 404: function() { alert( "Page not found" ); }}, success: function(jsonData) {...} }); SPECIFIC QUESTION: I would like to use the value of the variable
  6. So, I am trying to set up what I am calling a "Guided Tour" which uses CSS tooltips/popups to explain various parts of the page that they are on. I want the "tour" to run automatically, but also give them the ability to pause and continue it at any time, as well as go to the next and previous tip as needed. I'm finding this to be a bit more complex than originally anticipated. Mostly because it seems that using setTimeout() inside a for loop isn't that straight-forward. Let's start with my code: var startG = document.getElementById("startGuide"); var guidetips = []; guidetips[0]
  7. Greetings to all the users and administrators of w3scools invisionzone forum. I would love to get some constructive criticism on this web development tutorial site namely webtrickshome. It's been around for slightly more than a year but I redesigned it recently. Any feedback regarding the design and contents would be highly appreciated. Thankyou
  8. I have 3 files: html that is displaying data from json file using AngularJS, json file containing the data, script.js that stores the scripts. HTML file also has a form, from which I want to add data to my json file (onsubmit="insertData()"). insertData function is going to be in script.js I know, I may use .push method for this, but I don't know how to apply to the json file in this case. script.js var prg = angular.module('ajsprogram', []); prg.controller("outercont", function($scope, $http) { //function to display json file information $http.get('airlines
  9. BACKGROUND: It would be a long exercise in the grammar of the English language to explain what you can more readily understand by going directly to the relevant pages for which I provide the needed annotation below. gate7.html On this page you will find code that is identical in structure to six other pages similarly organized but with different content called gate1.html, gate2.html, gate3.html, gate4.html, gate5.html, gate6.html. The Javascript on this page and the other aforementioned pages performs two important functions: one, call a jQuery plug-in called $.colorbox that creat
  10. I have no idea where to put this topic so if it's in the wrong place, please forgive me. We have committees/teams in our organization (membership login on website) who should be able to create and edit certain pages of our website online. These are really novice users so basically all they'll be adding is text and pictures but they'll want to make it "pretty". I'm currently using WYSIWYG 14 and CoffeeCup editor to build the website. WYSIWYG has a CMS function in it but I can't get the editors to work properly once I publish it. WYSIWYG doesn't officially support them so I can't really ge
  11. OBJECTIVE: Suppress my site's splash panel for repeat visitors using a mechanism similar to the one that I use to suppress the panel for visitors whose viewports are too small to handle it properly. BACKGROUND: As I have instructed Matomo not to recognize me when I access the application I have no way of testing whether my code is working. According to a friend who has experimented with his own computer it does not. Although I am able to retrieve the cookie set by Matomo, I am now uncertain about how to handle it. NOTE: The cookie that Matomo appears to set is not set until the
  12. BACKGROUND: Having recently learned about localStorage and familiarized myself with its methods I would now like to apply it as suggested by one of W3Schools' mentors for the purpose of identifying return visitors. Searching on the internet turned up little that was very satisfying. QUESTION: Is there a standard routine for identifying return visitors or must I develop my own? Roddy
  13. BACKGROUND: I would like to use the following HTTP Request query string, but substitute the empty quotes with something like null or undefined. What are acceptable non-values in this instance? "https://www.nudge.online/_utilities/php/matomo/index.php?module=API&action=index&method=Events.getCategory&url=www.grammarcaptive.com&idSite=1&period=year&date=today&segment=''&expanded=''&secondaryDimension=''&format=json&token_auth=363130ebb19736863e42030f91269e40"; Roddy
  14. I want to use a gif I made for my sprite (it would be nice if the gif only played when the character moved) So far, I have a rectangle with choppy character movements. (It would also be nice if I could make the character movement smoother. I watched tons of tutorials but I couldn't find anything that shows how to do what I want to do. Here is the code <!DOCTYPE html> <html> <head> <style type="text/css"> #backgroundColor { width: 100px; height: 100px; background-color: white;
  15. This code works perfectly on a desktop or laptop, and on non-iOS mobile devices. It takes a thumbnail sample of an edited image and displays it at full size in a new canvas. On iOS, I just see a blank screen where the canvas should be. function click5() { document.getElementById("preview").style = "visibility:visible;"; document.getElementById("cPreviewCaption").style = "font-size:90%; font-weight:550; text-align:center; color:#FFFFFF; padding-top:6px;"; // Apply change to preview image which will open beneath thumbnails var cP = document.getElementById("cPrevie
  16. Hi everyone, I'm wondering it is possible to have few checkbox checked but count as one? For example, I put three checkbox on html, then checked two of three, but will count as one. Suppose I have group of checkbox, but considered count one from three checkbox checked. it will be very appreciate if you can help. Thanks, Gary
  17. BACKGROUND: The following piece of code is a little tricky, because it requires insight into more than what is shown. So, please allow me to show and tell, rather than only tell, and invite you to click on the menu option Sponsor Overview under the subheading Visitor Profile in the navigation bar of the Grammar Captive mainpage. Once arrived click on either of the two items entitled Visits per Number of Pages or Visits per Time Spent and then click again on the same item. What shows and what disappears are different. Now, I well understand why this occurs, but everything that I have t
  18. Hello I have a problem when it comes to traversing through DOM nodes and accessing their data(values). Please have a look at the following code HTML <!DOCTYPE html> <html> <head> <title>Page Title</title> <script src="js.js"></script> </head> <body> <div id="div1" class="div1"> <img src="1.png" style="width:100px;height:100px;"/> <h1>This is a Heading1</h1> <p>This is a paragraph1.</p> <button onclick="a(0);">Press me</button> </div> <div id="div1" class
  19. Is it possible to use this lightbox code with multiple galleries? At the moment, when using it with different galleries, lightbox will pop up, but it only show first gallery, and the others won't display. I have implemented this lightbox code with my PHP code and for the first gallery, everything is fine, but when I click others, only those gallery thumbnails will show up, but the currentSlide isn't and I understand that code changes only in the first gallery. My code: <div class="row"> <div class="row-inner" id="ajax-posts"> <?php while( $refs->h
  20. I copied the code straight from https://www.w3schools.com/nodejs/shownodejs_cmd.asp?filename=demo_events_open open.js var fs = require('fs'); var readStream = fs.createReadStream('./demofile.txt'); /*Write to the console when the file is opened:*/ readStream.on('open', function () { console.log('The file is open'); }); Upon executing "node open.js" in the terminal, "The file is open" appears in the terminal, then the program terminates. It always happens, even if I don't have demofile.txt open in Notepad or any other program. Not sure why this is happening? Wh
  21. BACKGROUND I have created two functions both of which have been tested and function as expected -- so well, in fact, that one of them can be used to enhance the output of the other. The problem arises when I seek to call these functions with separate button alerts provided below in the order given. Both functions are defined in a jQuery ready statement. BUTTON ALERTS <script> var num = 5; </script> <button onclick="alert(num.annotate('sec'));">Alert!</button> <script> var sec_num = 59039; </script> <button onclick="alert(secTranslate(sec_nu
  22. QUESTION: Does Javascript called from a cached file behave the same as Javascript called in a freshly loaded file? Roddy
  23. DILEMMA: I have a fairly complex JSON object that is introduced via an AJAX call. Unfortunately, my control panel tells me that it is undefined. Is this because it has no value? Or, is it because I do not know how to read the value properly? {"lastVisits"[{"firstVisit":{"prettyDate":"Monday, May 14, 2018"}}]} The name of the variable into which it is read is visitor_data. Am I reading the value of correctly? visitor_data.lastVisits[0].firstVisit.prettyDate Roddy
  24. DILEMMA: Visitors to the mainpage of my website can fill the middle section of the page from the page's navigation bar in either of two ways. Both ways employ Javascript: one, copy a div already on the page into another div on the same page; and two, copy the contents of a div on a another page into same. What I would like to do now is to copy the contents of a div already on the page with a call from the contents of a div that was previously on another page. QUESTION: How does one get a div to replace its own content when the div whose contents needs to be replaced has been filled w
  25. The DILEMMA: Recently I discovered how to enable responsive design on my website's main page. Although the page itself is now responsive, the splash panels that are associated with it are largely dysfunctional. Having experimented in various ways to make these latter responsive as well, I have decided to simply eliminate them on mobile devices. What is the best way to do this? Already I have combined PHP and Javascript to suppress the splash panels in the same session. So, my question is what is the best way to recognize any mobile device? Roddy
