jQuery has a trim function that can be used like:

var trimmedValue = $.trim(inputNameVal);

Also, inputNameVal.trim() is a function call that does not modify the value of the string, you'd have to have something like:

inputNameVal = inputNameVal.trim()

if String.trim is not defined for your browser mozilla documentation says you can define it yourself like:

if (!String.prototype.trim) {
  String.prototype.trim = function () {
    return this.replace(/^\s+|\s+$/g, '');
  };
}

String.trim() is not known by all browsers (see at the bottom of the page).

As you tagged this question with jQuery, you can use $.trim() like this :

$.trim(inputNameVal)
