Jquery check input trim

Question

How can i create a custom function in jquery?

I want to use that on text inputs, to check with trim, that the user really entered some text, or just white spaces.

use Jquery function $.trim on the value of the element – Deep Jul 23 '16 at 10:48 — Deep, Jul 23 '16 at 10:48

You can use .trim() function.

if ($.trim($("input-selector").val()))
{
   //do Something
}

He can check directly $.trim($("input-selector").val()); – Deep Jul 23 '16 at 10:47
You mean like this? kerdes_nev = $('#kerdes_nev').val(); if (!$.trim(kerdes_nev)) { FormErros.push("Show the error message...."); } – Takács Zoltán Jul 23 '16 at 11:00
