Replacing white space in a string

A handy little tip, if all you need to do is rip out spaces in a string don’t bother with using slice(), use regex instead. Copy the following line of code and replace ‘-’ with whatever you need to replace the space with…

yourString = yourString.replace(/\s+/g, '-');

So for example, if yourString=”blah blah blah”, it will now become “blah-blah-blah”. This is especially useful for amending URLs.

Removing non alpha-numeric characters from a string

Need to strip slashes, back slashes, hyphens and other symbols from a string? Looked at regex and cried “why? why? why?” at the moon repeatedly? Considered throwing your monitor out of the window? No worries. Here’s your solution:

var r:RegExp = new RegExp(/[^a-zA-Z 0-9]+/g) ;
yourString = yourString.replace(r, "");
