[Jscript]get a substring

Hi, is there an function which I can use to get a substring out of a text. In ASP I use left(string,pos) but now I need to declare it in a Javascript function so ASP won't work.

Tnx for your help!

Check this example:



You can use String.substring(a, b) to return the substring starting from the ath character up to but not including the bth character. The first character of a string is treated as character zero.

If a is less than zero substring will read the string from the first character. If b exceeds the string's length, then substring will read up up the the end of the string.

If a is equal to b, the empty string is returned.

If a is greater than b, substring will swap the start and end indices.

Tnx. I'd already searched at google but mostly I found large files with code to get a substring. I knew it would be simple.. I just hadn't the time searching for it.
