Can you move these util functions to a separate JavaScript file and include the file using the <script> tag?

Three (out of 8 or so) of the parameters in an object have an underscore at the beginning of their name. The underscores aren't in my json object and I can't decipher why Firebug would add them in.

This has the benefits of having the javascript cached before loading the page, but I'm ...

I am creating an internal web based application that will not be the target audience of the web. I understand the frustration of alert boxes and forcing people to do certain things. With that said, what I am attempting to do is create a javascript function, that unless a user clicks a link on a specific page, if they try to navigate aw...

Basically, I would like some idea of whether this is correct. Here is my thinking. Suppose I have one JavaScript file for five pages. If the u...

Firebug is great for javascript development, but doesn't allow to edit the code (the 'edit html' in the firebug is not usable, doesn't save the file and even if it did, it is just an plain text editor without any coloring). I usually have my editor opened next to Firefox, but the constant switching feels aarrgh! To have the editor insid...

We have an HTML page with multiple div blocks. We want to separate these div's into multiple files and then combine them all together into a single file - is it best to use server side includes (JSP in our case) or client side includes? Note that we're using JQuery - not sure if JQuery has a clever way to do the includes. ...
