Aurelia customAttribute 不工作

Question

我对 customAttribute 有疑问。我想用它来插入 jquery-ui 日期选择器。想法取自这里：http://www.danyow.net/jquery-ui-datepicker-with-aurelia/

但是看起来它根本不起作用。我试图调试应用程序，看起来 attached@datePicker.js 根本没有被触发。但是，文件本身是从服务器请求的。最糟糕的是我昨天晚上让它工作，但今天早上......

我在我的骨架应用程序分支中创建了简单示例：https://github.com/Exsilium122/skeleton-navigation 因此它已准备好进行克隆并运行进行故障排除。

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);
}

并且控制台是干净的：

Answer 1

刚做了一个：

从您的存储库中克隆
npm 安装 jspm
npm 安装
jspm 安装-y

你猜怎么着。它有效:)

Answer 2

attached = () => { 需要更改为 attached() {，如 gitter 中所述。

detached 方法需要进行相应的更改。

这个问题可以关闭了——OP 在 aurelia gitter 中解决了这个问题。
