JavaScript: IE11 String.trim() Prototype/Function

Create the String.trim() prototype for Internet Explorer 11.

Still developing for IE11? Well, this prototype is used to remote whitespace from the beginning and end of a string.


if (!String.prototype.trim) {
	String.prototype.trim = function () {
		return this.replace(/^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g, '');
	};
}

Using the above code snippet:


if (!String.prototype.trim) {
	String.prototype.trim = function () {
		return this.replace(/^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g, '');
	};
}
alert("     123     ".trim());
