I inherited a web site project that includes mootools.js (about 40k) in most of the scripts. However, I have not seen, intuitively, where it is being used and given the nature of this porject, ahem, I'm thinking it might not be being used at all! I'm "under the gun" to ship this tonight (yup, it's a pre-Thanksgiving release). I have not...

Only option right now seems to be changing the a...

I am trying to perform some computations on a server. For this, the client initially inputs some data which I am capturing through Javascript. Now, I would perhaps make a XMLHttpRequest to a server to send this data. Let's say the computation takes an hour and the client leaves the system or switches off the system. In practice, I woul...
I am doing iphone web development and I've noticed that: gesture events can also be touch events, which means a touch event handler also fires up when there is a gesture event. Any way that I can add specific event handler to gesture (not touch)? Or how can I know if this is a pure touch event or a pure gesture event? ...

I understand what closures are, but I am having some trouble grokking exactly what the term closure refers to. I have seen the term used in many websites, but rarely do they agree on the actual definition of it. Is it the variables that are kept on the stack frame? Is it the function that is being returned? Is it the scope of the oute...
