layer配合vue为什么弹窗回调里面拿不到data的值

Question

subContactUs: function getHomeData() {
    $.ajax({
        type: "get",
        data: {
            content: this.contactFrom.content,//这边没问题，可以拿到
            name: this.contactFrom.name,
            address: this.contactFrom.address
        },
        url: API.index.contactUs,
        dataType: "json",
        success: function success(res) {
            if (res.status == 1) {
                console.log(res);
                layer.open({
                    ... 
                    yes: function() {
                        this.contactFrom.name = '' //这边回调报nameundefind，这是为什么
                        layer.closeAll();
                    }
                });
            }
        }
    });
}

Answer 1

this的指向问题，用箭头函数，或者在最外层that = this，yes回调中使用that.contactFrom.name
