How could i do this...

Thanks..

(Assuming that you have a string and want to convert it to an array)Split method on strings splits strings on a separator.

var str = "name,address,state,city";
var arr = str.split(',');

if you have such string:

var _str= 'name,address,state,city';

to get array from string use split javascript function:

var arr = _str.split(",");

If they're strings, jut give it array notation:

var str = [name,address,state,city];

in this array str[0] would be name, etc. If they're not string's variables...I'm unsure what you're asking.
