這一節(jié)寫一個(gè)坑爹的閉包。
var students = [
{name: "小明"},
{name: "小虎"},
{name: "珊珊"},
{name: "小慧"},
{name: "大胖"}
];
var sports = [
"踢足球",
"打棒球",
"踢毽子",
"跳繩子",
"拔河"
];
for (var i = 0; i < students.length; i++) {
var sport = sports[i];
students[i].play = function(){
console.log( this.name + sport );
};
};
for (var j = 0; j < students.length; j++) {
students[j].play();
};
執(zhí)行結(jié)果 :
小明拔河
小虎拔河
珊珊拔河
小慧拔河
大胖拔河
