ng-sidebar（Angular 2）实现问题 [英] ng-sidebar (Angular 2) implementation issue

问题描述

我需要使用ng-sidebar在标题中单击按钮左侧显示可折叠的侧边栏菜单。

I need to make use of ng-sidebar to display a collapsible sidebar menu to the left on click on button in header.

app.component.html

app.component.html

<div class="page-header custom-phead">
    <ng-sidebar-container>
     <ng-sidebar [(opened)]="_opened">
        <p>Sidebar contents</p>
      </ng-sidebar>

<div ng-sidebar-content>
<button (click)="_toggleSidebar()">Toggle</button>
</div>
</ng-sidebar-container>
<form class="heading">
<input type="text" name="search" [(ngModel)]="search"><input type="image" [src]="'../resource/searchicon.png'">
</form>
</div>

在app.component.ts中，

And in app.component.ts ,

     private _opened: boolean = false;

  private _toggleSidebar() {
    this._opened = !this._opened;
  }

问题是，按钮根本不会反映在屏幕上，另外没有发生。请帮忙解决这个问题。

The problem is, button doesn't reflect on screen at all and in addition, none happens. Please help sort this out.

推荐答案

尝试将您的HTML更改为：

Try to change your HTML to something like:

<div class="page-header custom-phead">
  <ng-sidebar-container>
    <ng-sidebar [(opened)]="_opened">
      <p>Sidebar contents</p>
    </ng-sidebar>
    <!-- you can also try to add a div below if your content not visible -->
    <div style="clear:both;"></div>
  </ng-sidebar-container>

  <button (click)="_toggleSidebar()">Toggle</button>

  <form class="heading">
    <input type="text" name="search" [(ngModel)]="search">
    <input type="image" [src]="'../resource/searchicon.png'">
  </form>
</div>

请注意，我带< button（click）=_ toggleSidebar （）>切换< / button> 超出 ng-sidebar-container 。如果侧边栏内容仍然无法显示，请尝试在关闭<$ c之前添加< div style =clear：both;>< / div> $ c> ng-sidebar-container tag。

please note, that I took <button (click)="_toggleSidebar()">Toggle</button> out of ng-sidebar-container. If you sidebar content still does not get visible, try to add <div style="clear:both;"></div> just before closing ng-sidebar-container tag.

我创建了一个 plunker ，它使用两种方法切换侧边栏： [（已打开）] =_已打开和 close（）和 open（）函数。它可以帮助您完成项目

I created a plunker which uses both methods for toggling sidebar: [(opened)]="_opened" and close() and open() functions. It may help you with your project
