使用jQuery的Angular-cli和Karma [英] Angular-cli and Karma with jQuery
问题描述
我在网上搜索过,无法找到解决当前问题的方法,即使这似乎是非常常见的问题 ......
I have searched the web and could not find a solution for my current problem, even though seems to be a very common issue...
运行 ng test
时,我发现Karma浏览器打开并且没有显示任何内容:
When running ng test
I find that the Karma browser opens and shows nothing:
此外,这是我的控制台:
Also, this is my console:
为了使用jQuery,我做了解释的事情这里。
In order to use jQuery, I have done the things explained here.
这是我的 lib.ts
(基本上与 vendor.ts
相同):
// jQuery
declare let jQuery: any;
// RxJS
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/mergeMap';
// Dependencies
window['jQuery'] = require('jquery');
window['$'] = window['jQuery'];
import 'imports-loader?jQuery=jquery!jquery-color/jquery.color.js';
import 'jquery-ui-npm/jquery-ui.min.js';
require('bootstrap/js/tooltip.js'); // required for X-editable
require('bootstrap/js/popover.js'); // required for X-editable
require('bootstrap/js/dropdown.js'); // required for bootstrap-colorpicker
require('bootstrap/js/tab.js'); //
require('bootstrap/js/modal.js'); //
window['moment'] = require('moment');
import 'imports-loader?jQuery=jquery!jquery-color/jquery.color.js'
我将 lib.ts
导入 main.ts
。
最后,有问题的组成部分:
And finally, the problematic component:
aside-chat-boxes.ts:
'use strict';
declare let $: any;
$.widget("ui.chatbox", {
// A bunch of stuff here
}
我没有把这个组件的所有代码都放在为谁阅读。
I didn't put all the code of this component for the sake of who's reading.
推荐答案
通过将此添加到我的组件的顶部来解决这个问题:
Solved this by adding this to the top part of my component:
import $ from 'jquery/dist/jquery';
这不是我想要的解决方案,但它是一种有用的解决方法。
It's not the solution that I was looking for, but is a useful workaround.
我仍然对在Angular项目中使用jQuery时遇到的所有问题感到惊讶...
I'm still amazed of all the problems that we have when using jQuery in an Angular project...

最好的方法是将jQuery添加到 karma.conf
数组。例如:文件中的.js
:[]
The best approach should be to add jQuery to karma.conf.js
in the files: []
array. Such as:
files: [
// imports of dependencies
...
// importing jQuery
'node_modules/jquery/dist/jquery.min.js'
]
