你怎么知道一个元素与父元素的偏移量?或者我怎么知道滚动ScrollView有多少?
var obj = {
prop1 : 0,
prop2 : 1,
func1 : function (){
var x = {
func_Inner : function(){
//ATTEMPTING TO CALL FUNC2 ON obj WON'T WORK
this.func2()
//NEITHER THIS
//this.func2().bind(obj);
}
}
// Here's is bound to the current context.
x.func_Inner.bind(this)();
},
func2 : function (){
//console.log(this)
console.log(this.prop1,this.prop2)
}
}
obj.func1();
此选项不合适,因为它识别屏幕边缘的偏移,但不识别父元素的开头
