Question

i have a form that generates dynamic text inputs with ids like follows

<input id='item_blue_1' ...
<input id='item_green_2' ...
<input id='item_blue_3' ...
<input id='item_green_4' ...
<input id='item_blue_5' ...

how can i get all the values of only the elements that start with ids item_green, and put the values into a coma separated string or array, which ever is fastest and easiest?

Answer 1

use start with selector

var arr=[];
var ids=$("[id^=item_green]");
arr = $.map(ids, function(n, index){
  return ($(ids).eq(index).val());
});

var stringArr=arr.join(","); //for string values
