I am developing a small web-utility that displays some data from some database tables. I have the utility running fine on FF, Safari, Chrome..., but the memory management on IE8 is horrendous.

What bad things happen at the moment document.write() is invoked? I've heard bits and pieces about document.write having an adverse impact on the DOM or on the use of Javascript libraries. I have an issue in front of me that I suspect is related, but have not been able to find a concise summary of what damage the method does. ...
Now this may seem like a silly question, but I need to know how to remove a DOM element BEFORE it is displayed to the user. In short, I am using a div that has a background image alerting the user to enable javascript before proceeding. If the user has javascript enabled I am using jQuery to remove the DOM element, in this case $(".check...
Is this faster: $(document.links).filter('a.someClass') than just plain old this: $('a.someClass') ? I don't see anywhere in jQuery's code the utilization of document.links which gives you the collection of links on the document right away, than, it would seem, it would be faster to just filter in the collection instead of all the...
I'd like to build a windows forms app to allow users to make selections within the Browser object. I'd like to capture their selection (by index or DOM element - no too picky at this point) and use this information to query content from the page. How can I capture the DOM selection from my C# app code? ...
How would I go about creating a cross-browser script, that would intercept all events firing on a page/browser window/DOM-tree (regardless of browser)? What I'm hoping to accomplish is basically to get a better understanding of the different handling of events in different browsers; I know the basic theory, but need to see to believe......

Now when the user is at the top of the page and has not scrolled vertically, the DIV must be postioned below the heading. However, once the user scrol...

I'm trying to extend the DOMDocument class so as to make XPath selections easier. I wrote this piece of code: class myDOMDocument extends DOMDocument { function selectNodes($xpath){ $oxpath = new DOMXPath($this); return $oxpath->query($xpath); } function selectSingleNode($xpath){ return $this->selectNodes($xpath)->item(...
As noted by others, in Java, with the default W3C DOM libraries, one is required to use the Document object a factory to elements, i.e.: import org.w3c.dom.Document; import org.w3c.dom.Element; Document d; Element e; e = d.createElement("tag"); Why is that necessary? Why conceptually a method can't create an XML element without...

More specifically, is it possible to hinder a script element in DOM from running using userscripts/content scripts or similar in chrome or firefox? Tried using eventListeners on DO...

Is there any way to get the collection of all textNode objects within a document? getElementsByTagName() works great for Elements, but textNodes are not Elements. Update: I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I ...
