method_missing in JavaScript(SpiderMonkey)

   ruby的method_missing魔法在JavaScript中是否有类似等价物?答案是SpiderMonkey的__noSuchMethod__ 方法。演示如下(请firebug大神出马):
 

var obj = {};

obj.__noSuchMethod__ = function(/*String*/methodName,/*Array*/arrArguments){

    console.log(methodName, arrArguments);

}

obj.test(1,2);

// 打印出:"test", [1, 2]



总结:
  • ruby:method_missing
  • JavaScript(SpiderMonkey): __noSuchMethod__ (有可能会成为ECMAScript 3.1标准)
  • smalltalk:doesNotUnderstand
  • Objective-C:forward::
