  1. At Ingolme's suggestion, I've switched from simpleXML to DOMXML for this because I need to be able to replace a node. I've done my best to follow PHP.com examples, and everything seems to work up until the point of the actual replacement. I hope you can spot what's keeping it from working. The vars found in the heredoc are assigned earlier from the customer input form. if $found is positive, it contains a cId (customer ID) that exists in the DB and should be updated with any new info (code shown). If negative, it's abs() is the cId for a new node to be added (code omitted here). In $xm
  2. According to the "Node Types" table on this W3Schools page, only the Document Node has a limit to the number of child Nodes (other than None!) of any one type: The implication is that there can be any number of any other (listed) Child node in a Parent Node. For many Nodes, that's a natural state: An Element Node can have many other Child Element Nodes to define the complete Tree. For some Nodes, it's a little less natural: For example, one might think that a Comment Node is commenting on its Parent Node. Nope! A Comment Node is merely a child of its Parent, and is
  3. I'm just starting to use cookies for personalizing my website and I need a little clarification about the DOM. When a cookie is sent along with the request for a website, does it become available to the whole site (like every page you might load) or just to a specific page included in your website. I am planning on using the setcookie, getcookie and checkcookie functions from w3 - can I put them in any page of the website or do I have to use them from the initial page of my site? Any guidance would be appreciated.
  4. I copied and pasted a file from the w3 tutorial XML/AJAX application but changed just a couple of spots so it could read my own XML data file. It doesn't work - what am I missing, please. When I open the console in either google or IE it says xmlDoc is null or undefined - somehow I'm not 'reading' the file or something? can anybody explain it more. I've read over the toturials a couple of times and I think it should be working. I have also cleaned out the cach in the browser by hitting cntrl F5, which I learned from someone along the way. <!DOCTYPE html> <html>
  5. Hi, im a little bit struggling here. What I am trying to do is read the content from a Table by reading the number of rows and cells,(later on only selected rows by checkbox) then display the data in a ´generated Table (where i have to add cells with inputfields) So now my question is: How do i have to write the code so the first row will be created with <th> instead of <td> ? How to add input fields to the cells ? (actually they all could be input fields, just filled out with the data from the table i read from and blank fields for the added or so on.) function generate
  6. Hello, I found a function called fnGetSibling on https://msdn.microsoft.com/en-us/library/ms533043(v=vs.85).aspx#navigate and I was hoping to understand what it does return and why. var oPrevious = fnGetSibling(); function fnGetSibling(){ var oParent=oNode.parentElement; var iLength=oParent.children.length; for(var i=0;i < iLength;i++){ if(oParent.children[i]==oNode){ return oParent.children[i - 1]; break; } } } I have three possible options: 1. Finds and returns a reference to all childs of a node of DOM Tree. 2. Finds and returns a ref
  7. Hello and thank you all for bringing me into this forum. I would want to make a website about video games with news, articles, login system, etc., and I'm learning to make it with W3Schools. My issue is with the XML DOM. I tried to use JavaScript to add XML data (in the form of a news list) to my HTML page, so I used the following JavaScript code: var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (xhttp.readyState == 4 && xhttp.status == 200) { newsDisplay(xhttp); } }; xhttp.open("GET", "news.xml", true); xhttp.send(); function newsDisplay(xml
  8. Hello all, I have an SPA with a UI element akin to a directory tree (the grey column on the left) which allows the users to navigate the site's main content: The base of the code is implemented in the following HTML/CSS: <ul id="nav"> <li class="i"> <a href="Services">Services</a> <ul class="d"> <li> <a href="Services/Certificates">Certificates</a> </li> <li class="i"> <a href="Services/Responsabilities">Responsabilities</a> <ul class="d"> <li> <a href="Services/Res
  9. Hello internet, There is a webpage I would like to start building but I need to be able to pull data from other webpages. The information is public info so it’s nothing sketchy but I don’t know where to start. I began with just doing google searches but it appears it is more involved than I originally thought. If you have any recommendations on tutorials or Forum discussions I would be grateful. Thanks.
  10. I need to cut the program to the final logic cut. It's now ~10 times smaller, although it's as far as I could get in my understanding now.Given two identical text strings. When you write in <input> you should write letters which have to be identical to the given line. And while you're typing the cursor moves until the excercise_results().My program is still big, and I need some help in understanding it's actions. I know that each text contains a final dot and a space after it. But I couldn't link this with the number "2" in for loop (after hiding the color of the <p >passage -...te
  11. Hi, all, Swirling Dervish noobie here, and I can't seem to get one page element to "inherit" the height value of another: js: /* quotepick is the holder for the chosen display quote from the defText array; i is the index of the quote from the definition (defText) array; the goal is to get the div#jsGall2 (a backsplash to text) to inherit div#bennies' (text against the backsplash) height value. */ var quotePick = defText; if ((typeof quotePick) != 'undefined') { var dSize = document.getElementById("bennies"); var eSize = document.getElementById("jsGall2"); var b =
  12. Hello @ all, I'm again dive to a problem which is that, I want to create a progress updater using div and spans. that's roughly the idea of mine is: 1. A span is child of div. 2.

  13. Hi, I am trying to create a text tag where users can add comments, delete them and also choose where to insert that comment(if not default). My problem is how to give each new node a unique id, which should be a number 1, 2 and so on. Using these numbers, the user could select where to insert the new par or even to select which one to be deleted. To be honest I want to create a checkbox next to the new par, so the user can just thick which par to delete and then press the button, but I am open to better ideas:) For start could someone help me how to make it a create a unique id for eac
  14. Hi, I need to use getElementById to reference to a div which contains a pic and without changing anything in the body tag, a random image slideshow should appear on load! instead of that pic.

  16. I used loadXMLDoc to load an XML file onto my web page. I then saved different contents to a file of the save name. When I reloaded the file with loadXMLDoc, I got the original contents instead of the new contents. I deleted the file and then save the new contents to the file with the same name. Reloading still gave me the old contents. I then changed the name of the file. This time loading the file with loadXMLDoc gave me the new contents. Does loadXMLDoc remember the contents that was loaded from a file with a given name and not bother reloading the contents if I present it with a file of th

  18. I am developing a function to find a particular element within another element identifier (similar to getElementById but that applies to any other element) ... Because this throws me arror: var ancestor = document.getElementById('divAncestor');var child = ancestor.getElementById('divChild'); I know, HTML specifies that ids must be unique but reality proves that often running scripts that can have items with the same ids. So, thats the reason why I'm not simply calling the child like this: var ancestor = document.getElementById('divChild'); The first option was to add this function to e
  19. Hi, I intend to add a custom javascript object to the DOM of a HTML page to be able to access this object via its id (document.getElementById). Adding Nodes like Div..., that are known by DOM, works but where and how can I add the custom JScript Object. This is my testcode <!DOCTYPE html><html lang="en"> <head> <meta charset="utf-8"> <script type="text/javascript"> function initJScript(){ var customObject = new customObjectConstructor(); var testDiv = document.createElement('div'); alert(testDiv); alert(customObject);
  20. Hello, I have an XML file called cookbook.xml as well as an XSL file linked to it, called cookbook.xsl that presents all the information found in the .xml file in an html table (with headings, seperate cells, etc.) Now I want to create an html file that will presenet the above complete table on page load, as well as some query fields above that table, so that the table is refreshed according to a user's input (filters..) More specifically: XML file: For each cookbook (represented by a recipestories element), the file contains information about its title, author(s), year and page numbers, among
  21. Hello All, So you frequently see reductions with commonly used objects such as: var $this = $(this)//Or....var $objectName = $('.className') Is there any places or reason why you would chose to use the $ before the var name to create an object as oppose to just making a normal variable? I'm looking to find and replace the objects with these sorts of variables to reduce file size, make it easier to read, and hopefully speed up load time but to check with experts before I potentially F#$! up my work. Thoughts? Also, any thoughts on how to structure code (in general) to run most efficiently w
  22. Hi All, I've written some Javascript that will dynamically add "file" inputs to a form. They show up on the page just fine when the add control is clicked. But, when I submit the form, those dynamically added form fields are absent from the form structure on the receiving page. They're also absent from the form structure passed to the validation function. The added fields are added to a table within the form tags. The JS code adds table rows (TR). Then, cells are added to that row. Then, the file inputs to the cells. All this is done using DOM methods like appendChild(), createElement(),
