Aurelia customAttribute无法正常工作

Question

我有customAttribute的问题.我想用它来插入jquery-ui datepicker.从这里获取的想法:http://www.danyow.net/jquery-ui-datepicker-with-aurelia/

然而,看起来它根本不起作用.我试图调试应用程序,看起来像attach@datePicker.js根本没有被解雇.但是,正在从服务器请求文件本身.最糟糕的是我昨天晚上工作了,但今天早上......

我在我的骨架应用程序分支中创建了一个简单的示例:https://github.com/Exsilium122/skeleton-navigation, 因此可以克隆并运行以进行故障排除.

最重要的两个文件:

---

welcome.html

<template>
  <require from="./resources/datepicker"></require>
  <input id="myDate" datepicker="datepicker" value.bind="timestamp | dateFormat"/>
</template>

---

datepicker.js

import {inject, customAttribute} from 'aurelia-framework';
import 'jquery-ui';
import 'jquery-ui/themes/cupertino/jquery-ui.css!';

@customAttribute('datepicker')
@inject(Element)
export class Datepicker {
    constructor(element) {
        this.element = element;
    }

    attached = () => {
        console.log("attached Datepicker");
        $(this.element).datepicker({
            dateFormat: 'mm/dd/yy'
        }).on('change', e => fireEvent(e.target, 'input'));

    }

    detached = () => {
        console.log("detached Datepicker");
        $(this.element).datepicker('destroy').off('change');
    }
}

function createEvent(name) {
    var event = document.createEvent('Event');
    event.initEvent(name, true, true);
    return event;
}

function fireEvent(element, name) {
    var event = createEvent(name);
    element.dispatchEvent(event);
}

并且控制台很干净:

Answer 1

attached = () => {需要改变attached() {,正如gitter中所讨论的那样.

该detached方法需要相应的变化.

这个问题可以被关闭 - OP在aurelia gitter中解决了问题.
