es6类. this.addeventlistener [英] es6 class. this.addeventlistener

问题描述

我正在尝试在一个班级中添加一个事件侦听器，但一直出现此错误:

I am trying in a class to add an eventlistener but keep getting this error:

"TypeError:this.win.addEventListener不是函数"

"TypeError: this.win.addEventListener is not a function"

我该如何解决?

代码:

class Ui {
    constructor(el) {
        this.win = $(window);
        this.onResize = this.onResize.bind(this);
        this.init();
    }

    init() {
        console.log(this.win);
        this.addListeners();
    }

    addListeners() {
        this.win.addEventListener('resize', this.onResize);
    }

    onResize() {
        console.log('test');
    }
}

export default Ui;

推荐答案

jQuery实例没有addEventListener方法.改为使用 on .

jQuery instances do not have addEventListener method. Use on instead.

addListeners() {
    this.win.on('resize', this.onResize);
}
