[jQuery] Re: Test if jquery has loaded

[Shawn]

It's not a case of the alert not showing up.  That would result in an 
error halting all processing.  So for a human sitting at the screen that 
would give us the data he wanted.  But for code that needs to do 
something differently if jQuery were not loaded, the alert method would 
just fail and the alternate code would never fire.

Of course, it comes down to what the coder really wants.  He/she now has 
two options.

 Thats the point.
 
 He wanted to know how to check if it was loaded or not, so If the alert 
 doesnt show up, its not loaded.

 You could try something like this:
 
 if (jQuery) { alert(jQuery loaded); }
 
 I haven't tested this but don't see why it wouldn't work...

Sure. You could do this:

if (typeof jQuery != 'undefined') {
// do something
}
