JS_常用方法_一段用于DEBUG的代码

好像是在<<王者归来>>上面看到的,如下:

 

 

//调试级别var DebugLevel = {Info:1,Warning:2,Error:3,Off:4};var Debug = {level:DebugLevel.Info, //调试等级//_output:alert, //输入方法,可改为document.write(IE only)_output:function(x){alert(x);}, //输入方法,可为document.write//watch method,监视对象属性值_watch:function(obj,property){var ret = [];if(!(obj instanceof Object)){ret.push(obj);}else if(property) ret.push(property + ":" + obj[property]);else for(var each in obj){ret.push(each+":"+obj[each]);}return ret;},Output:function(level,args){for(var i=0;i<args.length;i++){if(Debug.level<=level){Debug._output("level " +level + " : " +Debug._watch(args[i]));}}},Info:function(){Debug.Output(DebugLevel.Info,arguments);},Warning:function(){Debug.Output(DebugLevel.Warning,arguments);},Error:function(){Debug.Output(DebugLevel.Error,arguments);}}//Debug.level = DebugLevel.Info;Debug.Info("test");var o1 = {"a":1,"b":2,"c":3};Debug.Warning(o1);
