我想定期更新一个js物体(在标的产生之后)。

var data = {
    foo: -1,
    bar: -1,
    refresh: function() {
        this.foo = getFoo();
        this.bar = getBar();
    }()
}

目前,这一意向似乎是指数据标。 我可以在这里尝试的是几处不同的ations子,但想知道,我是否在 here上错树? 在我需要定期更新的物体(所谓外部)时,我应当使用哪种模式。

最佳回答

页: 1

var data = {
    foo: -1,
    bar: -1,
    refresh: function() {
        this.foo = getFoo();
        this.bar = getBar();
    } // <== here
};    // <== Also, semicolon here for best practice

使用:

data.refresh();

您需要提供<条码>植被/代码>和<条码>、植被/编码>功能,或接受对<条码>的论证。 e.g:

var data = {
    foo: -1,
    bar: -1,
    refresh: function(newFoo, newBar) {
        this.foo = newFoo;
        this.bar = newBar;
    }
};

使用:

data.refresh(42, 52);
问题回答

。 在你的情况下,你立即自动援引,因此可在<代码>window<>>> 代码上援引。

你可以做的是:

var data = {
    foo: -1,
    bar: -1,
    refresh: function() {
        this.foo = getFoo();
        this.bar = getBar();
    }
}
data.refresh();
