edit: jquery_time.js:

;(function($) {     $.timer = function(func, time, autostart) {          this.set = function(func, time, autostart) {             this.init = true;             if(typeof func == 'object') {                 var paramlist = ['autostart', 'time'];                 for(var arg in paramlist) {if(func[paramlist[arg]] != undefined) {eval(paramlist[arg] + " = func[paramlist[arg]]");}};                 func = func.action;             }             if(typeof func == 'function') {this.action = func;}             if(!isnan(time)) {this.intervaltime = time;}             if(autostart && !this.isactive) {                 this.isactive = true;                 this.settimer();             }             return this;         };         this.once = function(time) {             var timer = this;             if(isnan(time)) {time = 0;}             window.settimeout(function() {timer.action();}, time);             return this;         };         this.play = function(reset) {             if(!this.isactive) {                 if(reset) {this.settimer();}                 else {this.settimer(this.remaining);}                 this.isactive = true;             }             return this;         };         this.pause = function() {             if(this.isactive) {                 this.isactive = false;                 this.remaining -= new date() - this.last;                 this.cleartimer();             }             return this;         };         this.stop = function() {             this.isactive = false;             this.remaining = this.intervaltime;             this.cleartimer();             return this;         };         this.toggle = function(reset) {             if(this.isactive) {this.pause();}             else if(reset) {this.play(true);}             else {this.play();}             return this;         };         this.reset = function() {             this.isactive = false;             this.play(true);             return this;         };         this.cleartimer = function() {             window.cleartimeout(this.timeoutobject);         };         this.settimer = function(time) {             var timer = this;             if(typeof this.action != 'function') {return;}             if(isnan(time)) {time = this.intervaltime;}             this.remaining = time;             this.last = new date();             this.cleartimer();             this.timeoutobject = window.settimeout(function() {timer.go();}, time);         };         this.go = function() {             if(this.isactive) {                 this.action();                 this.settimer();             }         };          if(this.init) {             return new $.timer(func, time, autostart);         } else {             this.set(func, time, autostart);             return this;         }     }; })(jquery);
