Re: [問題] 在Function中取得Function Name
※ 引述《IwillSay (我將會)》之銘言：
: 請問假如我有一個object長這樣
: var fns = {
: MethodA : function() {
: //alert(???); 在這邊取得MethodA的字串
: }
: };
: 請問有辦法在MethodA裡面取得他對應的Property Name嗎(MethodA)
var fns = {
a1 : 123,
a2 : 456,
a3 :"xxx",
Method1 : function() {
alert(this.a1);
},
MethodA : function (){
var name;
for (name in this) {
if (this.hasOwnProperty(name) && typeof this[name] === 'function' &&
arguments.callee === this[name]) {
break;
}
}
alert(name);
},
Method2 : function() {
alert(this.a2);
}
};
fns.Method1();
fns.Method2();
fns.MethodA();

先用for 循環this
由於for in 會讀取所有prototype chain 上的 property
所以用hasOwnProperty過濾
並用typeof 只讀取function
最後再比對是不是同一個function object
