What is the best way to trim() in javascript

Question

The question says it all; JS doesn\'t seem to have a native trim() method.

Answer 1

I use this with native JavaScript

// Adding trim function to String object if its not there
if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, '');
  }
}

Use like this

var myString = "                  some text                  ";

alert(myString.trim());

Example

// Adding trim function to String object if its not there
if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, '');
  }
}

var str = "      some text              ";
console.log(str.trim());
