Split string into 2 elements [closed]

by

You can do this with the String.split function, which splits a string into an array using a separator/token:

var token = 'begin';
var str="beginThetest";
var parts = str.split(token);

alert(parts[0]);   //'Thetest'

If you don’t fully understand String.split:

The parts array only contains one element (parts[0]) because there are no characters before the only occurrence of the token ('begin') in your string.

A lengthier example should make this clear:

var token = 'begin';
var str="THIS_TESTbeginTHAT_TESTbeginLAST_TEST";
var parts = str.split(token);

alert(parts[0]);   //'THIS_TEST'
alert(parts[1]);   //'THAT_TEST'
alert(parts[2]);   //'LAST_TEST'

But if 'begin' is always your token, what’s the point? You don’t need to split, you can just do something like:

var str="beginThetest";
var token = 'begin';
var index = token.length;

var the_rest = str.substr(index);
alert(the_rest);    //'Thetest'

And of course you can put that into an array if you’d like.
