JavaScript split string to array of int

Question

I have a string that's on the page and from which I want an array of int.

<div id="TheData">2,3,0,43,23,53</div> 

I'm writing this:

var ArrayData = ($('#TheData').html()).split(','); 

However, ArrayData becomes an array of strings. How can I get an array of ints? Note that some of the elements in the HTML can be equal to 0.

Thanks.

Answer 1

var ArrayData = $('#TheData').html().split(',').map( Number ); 

Add Array.prototype.map() to older browsers with the code from MDN.

You can use jQuery's $.map() in the same manner, though it won't work with $.prototype.map().

var ArrayData = $.map( $('#TheData').html().split(','), Number );
