Question

My data[l][m] contains 1,2,3,4,5 I\'m trying to search for a particular number, say \'2\' in it. Is there a better way to do this?

Answer 1

If you're already including jQuery, use $.inArray(), like this:

if($.inArray(num, data[l][m]) > -1) {
  number = data[l][0];
  document.form.options[l-1] = new Option(number,number,true,true);
}

The shorter vanilla JS version is a direct .indexOf() on the Array, but IE doesn't have this by default.
