Today I stumbled upon the possibility to access a DOM element in Javascript simply by its id e.g. like this: elementid.style.backgroundColor = "blue" I tested with a very short snippet if this works in IE, Firefox and Chrome - and it does. Here is the snippet I used: <html><head> <script> function highlight() { content.st...
I know Firebug is the standard, but I find myself using Chrome a lot (screen space, speed, etc.) Anyway, I think their inspector is pretty good, too. Certainly good enough that I don't want to fire up FF and navigate thru a site every time that I want to take a peak at the DOM. However, probably the most annoying part is that I can't do...
I want to determine the mimetype of a webpage. I am specifically looking for a statement like this, which works for Firefox: if (document.contentType == 'text/html') { performX(); } else { performY(); } However, a statement which works across all browsers is preferred. Some google result suggested me this, but it fail...
Hi. I'm looking for a way to access read-only properties of a page on a IFRAME. Specifically I would like to read the selection. Apparently I can't read it because the document lies on another domain. Is there a way to read them? ...
This is a challenge question / problem. Hope you find it interesing. Scenario: You have a very long list (unreasonably long) in a single column. It would be much better displayed in multiple shorter columns. Using jQuery or another tool, what do you do? The format of the list is as follows: <div class="toc"> <dl> <dt>item 1</dt> ...

Hello: I am trying to write a javascript function with an "if" statement that will execute a command if the text between two tags match. I have been able to write many "if" statements in which a command is executed when the value within an input textbox equals that of the "if" statement criteria such as: function Test() { if (docu...

I am trying to change the class of a element with Javascript using the below code: parent.document.getElementById('<?php echo $markid ?>').class = 'unlistened'; Not having much luck though. How do I do this properly? ...
Is there a way to access the DOM-Elements of a mxml file in a way that you can in JS (e.g. using Prototype or jQuery)? I need to know if a top-level element has a child (sub-sub-...-childs) with a certain id. In JS (using prototype) it would be something like: $('tabs').select('[id="something"]'); Any ideas? ...
I have a list of check boxes. For the check boxes that are selected, I change it's name before submitting. In FF the function works. In IE I get: A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script? YES/NO Not sur...

I am finding it difficult to do some basic operations, and namely: clear content of DOM element append to content of DOM element In jQuery, I would do: $(".someSelector").empty().append("<div>something</div>"); How to do the above ...

Why does $(".bold").hide(); <--This work $("tcol1").hide(); <--This NOT work?? The second column has the same name and id for all rows:. <tr> <td>data1</td> <td name="tcol1" id="tco...
Cryptic title, but it's hard to explain. With Firefox, head over to http://images.google.com do a random search, and then drag the first search result to the URL bar. You'll see it it goes to the page that had the image anchor. Then click the "see full size image" link, and then drag the image to the address bar. In the first example...
Say,is the following possible: textNode.appendChild(elementNode); elementNode refers to those with nodeType=1 textNode refers to those with nodeType=2 It's not easy to produce. The reason I ask this is that I find a function that adds a cite link to the end of a quotation: function displayCitations() { var quotes = document.getE...
I want to select only the elements on the first "level". Ex: <div id="BaseElement"> <p>My paragraph 0</p> <div> <span>My Span 0</span> <span>My Span 1</span> </div> <span>MySpan 2</span> <span>MySpan 3</span> <p>My paragraph 1</p> </div> Let's say that you got the BaseElement node. var Element = $("div#BaseElemen...
Not that it matters strictly, and maybe I just don't yet fully understand how the DOM works by asking this, but I'm just trying to anticipate if there is some kind of memory leak potential here. If I remove an element that has children, event listeners, etc., do those get cleaned up as well? Or would I be wise to implement some kind of...

Hello.

It's something like: <div class="this_div">content_of_this_div</div> So, I thought that maybe ...
I am loading HTML into DOM and then querying it using XPath in PHP. My current problem is how do I find out how many matches have been made, and once that is ascertained, how do I access them? I currently have this dirty solution: $i = 0; foreach($nodes as $node) { echo $dom->savexml($nodes->item($i)); $i++; ...
