JavaScript split string to array of int

Solution 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 );

Solution 2:

var ArrayData = $.map($('#TheData').text().split(','), function(value){
    return parseInt(value, 10);
    // or return +value; which handles float values as well
});

You can use $.map to transform the array of strings to ints by calling parseInt on each of the elements in the array
