Splitting Strings In Javascript

I have variable named s in javascript.It contains value as '40&lngDesignID=1'.I want to split it with & and want to get 40 and lngDesignID=1.How can i do that in javascript

Solution 1:

Use s.split("&") to return an array of elements.

varstring = "40&lngDesignID=1";
var splitVals = string.split("&");

alert(splitVals[0]); // Alerts '40'
alert(splitVals[1]); // Alerts 'lngDesignID=1'

Solution 2:

var yourString = '40&lngDesignID=1';

var arr = yourString.split('&');
alert(arr);

Then arr[0] will hold '40' and arr[1] will hold the value 'lngDesignID=1'.

Also, javascript split accepts regular expressions, so you could also break up the string further if needed.

var yourString = '40&lngDesignID=1';

var arr = yourString.split(/[&=]/);
alert(arr);

This version splits the input into 3 parts; 40, lngDesignID, and 1.
