Disable Select Options in Internet Explorer

Put your hands up if you hate developing for Internet explorer….

Uppercase First letters with javascript

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.
