javascript - javascript覆盖类变量

Question

我有带变量的类，我想通过外部文件中的另一个函数更改变量值

班级代码

frappe.ui.Notifications = class Notifications {
    constructor() {
        frappe.model
            .with_doc('Notification Settings', frappe.session.user)
            .then(doc => {
                this.notifications_settings = doc;
                this.make();
            });
    }

    make() {
        this.$dropdown = $('.navbar').find('.dropdown-notifications');
        this.$dropdown_list = this.$dropdown.find('.notifications-list');
        this.$notification_indicator = this.$dropdown.find('.notifications-indicator');
    }
};

我想改变变量this.$dropdown

frappe.ui.Notifications.$dropdown =  $('.Header').find('.dropdown-item-notifications');

Answer 1

Notification 类实例设置为frappe.frappe_toolbar.notifications。您可以使用它来覆盖该属性。

frappe.frappe_toolbar.notifications.$dropdown = $('.Header').find('.dropdown-item-notifications');
