var arr;
arr[0] = 'size:256';
var vals = $(arr[0]).split(':');
alert(vals);​

There is no need in jQuery, just pure JavaScript. String split is native JS function.

var arr = [];     // and don't forget to initialize array
arr[0] = 'size:256';

var vals = arr[0].split(':');
alert(vals[0]);   // gives "size"
alert(vals[1]);   // gives "256"
