#javascript #jquery #trim I get tired of removing the blank spaces everywhere, ... If I just realize months ago that I can do this !

string_helpers.js

// Load after jquery.js
// Instead of $('#my_input').val(), do $('#my_input').trimmed_val()

(function() {
  String.prototype.trim = function(){return this.replace(/^\s+|\s+$/g, '');};
  
  String.prototype.ltrim = function(){return this.replace(/^\s+/,'');};
  
  String.prototype.rtrim = function(){return this.replace(/\s+$/,'');};
  
  String.prototype.fulltrim = function(){
    return this.replace(/(?:(?:^|\n)\s+|\s+(?:$|\n))/g,'').replace(/\s+/g,' ');
  };
  
  $.fn.trimmed_val = function(value) {
    if ( !arguments.length ) {
      return $.fn.val(value).fulltrim();
    } else {
      return $.fn.val(value.fulltrim());
    }
  }

}($));
