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.
The latest one I have had to find and put into practice is a method for disabling some Select dropdown options in a form. Internet explorer doesn’t support the disabled attribute on option elements. The following code will only work in standards complaint browsers (not in IE 6 or 7):
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.
