jQuery has a great helper function called hover which takes two functions as it’s values.
$('#hover_div').hover(function()
{
/* something to do on mouseenter */
},
function()
{
/* something to do on mouseleave */
});Great when you want a simple way of doing something when your mouse enters or leaves the selected element(s).
Put your hands up if you hate developing for Internet explorer….
That would be most of you then.
I can’t stand its special ways of doing things, so when I find an easy work around it makes me happy.

If you have a string in javascript and you want to the first letter to be uppercase / a capital then this line of code will do that for you:
str = str.slice(0,1).toUpperCase() + str.slice(1);If you want to convert more than one letter then you might want to use the following. As examples if you wanted the first 4 characters uppercase use (0,3) and then (4) and if you wanted the first 2 uppercase you would use (0,1) and then (2)
str = str.slice(0,3).toUpperCase + str.slice(4);Remember that an array starts at zero so always take one from the numbers you want.
I have been doing a lot of javascript coding recently. It’s funny because until six months ago I was a javascript beginner. I had done some js but didn’t completely get it and began by copying and pasting from other sites in the hope that things would just work. Then again that’s how I started with php too.
As I began to work on PagePlay more and more the javascript needed to be more and more clean and easy to adapt for when we add new functionality.
