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::
