Getting Id that contains a string using Jquery

Question

I want to get all the values contained in some input texts. The Ids of the inputs are something like something_#index#_value assuming that #index# is an integer so the first Id is something_1_value.

This is what I've tried so far :

$("input[id$='_value'] [id*=i]").each(function (j, el) { // Some actions }

Assuming that i is an int, the selector doesn't return any value, and when I delete the [id*=i], I get all the element where the Id finishes with _value.

So how can I get the values of elements that finishes with _value AND containes the integer i in it's Id?

use string concatenation - $('input[id$="_value"][id*=' + i + '"]') — Arun P Johny

Arun has answered your question, but your basic strategy appears to be flawed -- for instance, $('input[id$="_value"][id*="1"]') will match both id 1 and id 11 (or 12, 13, etc.). — Frédéric Hamidi

Thanks @FrédéricHamidi, I know I just wanted to simplify my question, actually I'm checking if my Id Contains "_i_" not just "i". — TheByeByeMan

You need to use string concatenation to use the value of variable i - you are trying to find input elements with id ending with _value and has an i in its id

$('input[id$="_value"][id*="' + i + '"]')

But since you can get complete id, you can use the id selector also

$('#something_' + i + '_value')
