This is something of an embarrassing question to ask, seeing as it is mainly about my lack of Javascript knowledge. Seems like it might be "so obvious" that nobody specifies it anymore. Gotta start somewhere! I'm a proficient coder in other languages, I'm just unfamiliar with JS. On the ReCaptcha Client API docs page, there's an example...

I'm working on a image viewer that has a draggable scrollbar. When the user drags the scrollbar, some of the text on the webpage becomes selected. I've tried window.getSelection().removeAllRanges(); but that doesn't seem to work in IE7/8. Also tried the document.getSelection().removeAllRanges(); which seems to work just as "well" w...

Okay, my situation is such: I need to send the contents of a JavaScript array to server where a PHP script will persist individual array entries in a MYSQL database. I am NOT using jQuery but I am about to integrate Prototype framework into my project. I gather that the JS array can easily be converted to JSON using the toJSON() method ...
I am trying to understand why you would use jQuery.get() and jQuery.get(index). The docs say it is to convert the jQuery selection to the raw DOM object instead of working with the selection as a jQuery object and the methods available to it. So a quick example: $("div").get(0).innerHTML; is the same as: $("div").html(); Obviousl...

Once the user hovers over the table row it removes the pre defined background color for that row. I want to make it so that way it does not overwrite this style. How might I do that? <script type="text/java...

I have gone insane trying to figure out how to make this work.
