[英]multi inherit or access the property and method outside the object
var ob = function(){
};
ob.prototype.func = function(){
};
var t = function(){
this.p=0;
this.function1(){
}
var a=new ob();
a.func=function(){//overrides the func
//hope to access this.p this.function1
}
};
是否可以使can可以訪問this.p this.function1?
歡迎您發表評論
如果要在a.func
訪問它,則需要在t
內部保留this
的引用。 請嘗試以下操作:
var t = function(){
var this_t = this; // Use this_t to access this.p and this.function1 inside a
this.p=0;
this.function1 = function(){
}
var a=new ob();
a.func = function(){//overrides the func
this_t.p = 1;
this_t.function1();
}
};
