Im learning to use javascript at the moment
and have had a little trouble
in my page i have this

var text_sting=('winamp_ra_28k")

how do i cut up the string at the underscores so i have three different var's
eg
var1 = winamp
var2 = ra
var3 = 28k

Use the .index, .length, and .substring functions

text_string = new String("winamp_ra_28k");

//search for position of first _
temp = text_string.indexOf("_");
//search for position of next underscore
temp2= text_string.indexOf("_",temp+1);

//assign first string from start to temp(non-inclusive)
first_string=text_string.substring(0,temp);
//assign second string from temp+1 to temp2(non-inclusive)
second_string=text_string.substring(temp+1,temp2);
//assign third string from temp2+1 to end of string
third_string=text_string.substring(temp2+1,text_string.length);

Alternatively you can use the split() method which was introduced into IE4 and NN4.

var textStr = "winamp_ra_28k";

This creates a new array with three separate entries:

var txtStrArray = textStr.split("_");

If you want to store them into three separate variables:

var textStr1 = txtStrArray[0];
var textStr2 = txtStrArray[1];
var textStr3 = txtStrArray[2];
