Hi, I'm converting some Java code to Javascript, and the Java object has a Static Initialization block that populates two arrays in the object. My understanding is that this initializer runs only once no matter how many objects are created. Can I do such a thing in Javascript? Java code: public final class MyObject { priv...
I'm designing a page for a kiosk at a local business that displays both a flash solar monitor as well as a slideshow of images of their new green roof but want a way to focus on each of these objects individually, making the one in focus larger in the foreground while having the other smaller and more subtle in the background or on the s...

As I don't want the client to run into memory issues, I want to lazy-load the markers and apply them to Fluster2 to put them into clusters. I think the best way to lazy-load the markers is to add...

Using PHP, I scan a directory and list all of the .xml files. Each XML file contains both a "name" element and a "date" element. The "name" element for each XML file is listed as an option in the select list. This works perfectly fine, however, the "date" element in each XML file is different and contains a date format like this: mm/dd...

Hi everyone, As the title, how can I remove a div on the html title using javascript or jquery framework? I know it sounds weird but currently I'm working on a CMS template and the generate title has around the title <title><div id="title">Title of the page</div></title> Any help appreciated ...
The good browsers all work such that an empty "title" attribute for an element means, "don't bother to show a title flyover here". That makes sense, as a little white flyover with nothing in it (edit or nothing but a space character) is, for most people, completely useless. The designers of IE do not agree. My problem is that I've go...
Since the JSON format specifies that single quotes should not be escaped, most libraries (or even the native JSON parser) will fail if you have an escaped single quote in it. Now this usually is not a problem since most of the time you do an XHR that fetches some data formatted as JSON and you use the responseText which contains your JSO...
