jQuery Object doesn't support property or method trim() in IE

Solution 1:

IE doesn't have a string.trim() method.

Instead, you can call jQuery's $.trim(str).

Solution 2:

You can add trim() method on String object, for browsers without support for this method (IE alike).

Simply add these lines before you call trim() method:

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

Solution 3:

trim() is not invoked like that in a jQuery context.

Once you call attr(), that's the end of jQuery chaining. See http://api.jquery.com/attr/

To do this, do:

jQuery.trim(jQuery('#Reminders').attr('value'));

See: http://api.jquery.com/jQuery.trim/

Solution 4:

Same problem here with IE not having the trim() method. I solved by adding the trim() if it doesn't exist.

(function(str) {
    if (typeof(str.prototype.trim) === 'undefined') {
        str.prototype.trim = function() {
            return $.trim(this);
        };
    }
})(String);

Works great.
