jquery doens不工作角5

Question

我正在尝试在角度5中使用jquery，特别是我正在尝试使用此库：

https://codepen.io/rstrahl/pen/eJZQej

以下是步骤：

- ＆gt;我创建了一个新应用

ng new myApp

- ＆gt;导航到新的角度应用

cd myApp

- ＆gt;安装依赖项：

npm i @angular-devkit/core

- ＆gt; cd src

- ＆gt; cd app

- ＆gt; mkdir components

- ＆gt; cd components

- ＆gt;我创建了一个组件

ng g component myComponent1

- ＆gt;在package.json中，在依赖项部分中，添加1.11.3

- ＆gt;在index.html中添加对jquery和librery的引用：

- ＆gt;这是my-component1组件html：

<div class="page-container">

  <h1>
     jquery-resizable - A simple splitter panel
  </h1>
  <hr />

  <p>
      Simple example that demonstrates how to create slidable two-pane layouts <a href="http://caniuse.com/#search=flexbox">using FlexBox</a> and the resizable plug-in.
      Note that Flexbox is not required, but used here to keep the layout simple.
  </p>

  <label>Horizontal Splitter Panes:</label>

  <div class="panel-container">

      <div class="panel-left">
          left panel
      </div>

      <div class="splitter">
      </div>

      <div class="panel-right">
          right panel
      </div>
  </div>

  <label>Vertical Splitter Panes:</label>
  <div class="panel-container-vertical">

      <div class="panel-top">
          top panel
      </div>

      <div class="splitter-horizontal">
      </div>

      <div id="panel-bottom">
          bottom panel
      </div>
  </div>



  <hr />

  <p>
      This example creates two resizables for the horizontal and vertical splitter panes:

</div>

- ＆gt;这是my-component1.component.css

html,

  margin: 20px;
  padding: 10px;

  border: 1px solid silver;
  border-radius: 4px;
  overflow: auto;
}

- ＆gt;这是my-component1.component.ts

import { Component, OnInit } from '@angular/core';
declare var jquery:any;
declare var $ :any;

@Component({
  selector: 'app-my-component1',
  templateUrl: './my-component1.component.html',
  styleUrls: ['./my-component1.component.css']
})
export class MyComponent1Component implements OnInit {

  constructor() { }

  ngOnInit() {
    $(".panel-left").resizable({
      handleSelector: ".splitter",
      resizeHeight: false
    });

    $(".panel-top").animate({height:'72px'}, 500);
  }

}

<app-my-component1>loading...</app-my-component1>

- ＆gt;这是app.component.html

<app-my-component1>loading...</app-my-component1>

- ＆gt;这是app.module.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
}

jquery动画在角度不起作用，有人可以纠正我的步骤和/或我的代码

非常感谢！

你不应该在Angular中使用jQuery。虽然有可能（怎么做，你可以在这里看到How to use jQuery Plugin with Angular 4?），但是不鼓励。

Angular在其内存中拥有DOM的自己的表示，并且不使用像jQuery这样的查询选择器。相反，所有DOM操作都由Renderer2完成（和Angular-directives一样，* ngFor和* ngIf在后台/框架代码中访问Renderer2）。如果您自己使用jQuery操作DOM，您迟早会遇到同步问题并且在屏幕上错误地显示或不正确地消失，错误并且无法正确测试应用程序（Jasmine要求您知道何时元素已被渲染）或能够使用Angular Universal。
