Question

trim() javascript function not working in IE7 however it' working fine in all other version and all browser. what should be issue with IE7 or how i can resolve this?

$("#Email").val().trim()

Thanks in advance.

Answer 1

IE doesn't support String.prototype.trim() until IE9.

It looks like you're using jQuery, so you can use $.trim() instead.

$.trim($("#Email").val())

Answer 2

The val() method doesn't always return a string . If the selected item is an option it can return an array which doesn't support trim . Have you checked the type of val() to see if it's actually a string ?

Note: As others have pointed out trim isn't supported on IE7 even if this is a string . Need at least IE9.
