html - 在角度 4 中切换三个 div

问题描述

我正在查看在我的 angular 4 应用程序中的三个 div 之间切换。对于以下损益表现金流量表资产负债表，我基本上有三个 div

如果您注意到 ul-li 标记中的锚标记。单击锚标记应显示相应的 div。我已将 href 设置为 href="javascript:void(0); 并尝试基于组件代码上默认设置为 true 的 showTable 变量进行切换。由于某种原因它不起作用。有人可以告诉我我该怎么做去实现它

<div class="card-body">
            <ul class="nav nav-pills financial-tab" id="financial-tab" role="tablist">
                <li class="nav-item">
                    <a class="nav-link active" [ngClass]="showTable ? '' : 'active' " id="sincome-tab" data-toggle="pill" href="javascript:void(0);" role="tab" aria-controls="table"
                        aria-selected="true" (click)="showTable = !showTable">Income Statement</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" [ngClass]="!showTable ? '' : 'active' " id="cash-tab" data-toggle="pill" href="javascript:void(0);" role="tab" aria-controls="chart"
                        aria-selected="false" (click)="showTable = !showTable">Cash Flow Statement</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" [ngClass]="!showTable ? '' : 'active' " id="balance-tab" data-toggle="pill" href="javascript:void(0);" role="tab" aria-controls="chart"
                        aria-selected="false" (click)="showTable = !showTable">Balance Sheet</a>

解决方案

如果您想根据锚点单击显示 div 并切换，请执行以下操作。

displayDivNumber:number;

onAnchorClick(no) {
 this.displayDivNumber = no;
}

带有 ngSwitch 的 html

<a (click)= "onAnchorClick(1)"> </a>
<a (click)= "onAnchorClick(2)"> </a>
<a (click)= "onAnchorClick(3)"> </a>

<div [ngSwitch]="displayDivNumber">
      <div *ngSwitchCase="1">Tab content 1</div>
      <div *ngSwitchCase="2">Tab content 2</div>
      <div *ngSwitchCase="3">Tab content 3</div>
</div>

或者如果需要单独打开/关闭可见，那么您应该尝试通过为每个变量创建单独的变量来执行以下操作。

displayDiv1:boolean=true;
displayDiv2:boolean=false;
displayDiv3:boolean=false;    
onAnchorClick(no) {
 if(no===1) {
  displayDiv1 = !displayDiv1;
 } else if(no===2) {
  displayDiv2 = !displayDiv2;
 } else if(no===3) {
  displayDiv3 = !displayDiv3;
 }
}

html

<a (click)= "onAnchorClick(1)"> </a>
<a (click)= "onAnchorClick(2)"> </a>
<a (click)= "onAnchorClick(3)"> </a>

<div [ngSwitch]="displayDivNumber">
      <div *ngIf="displayDiv1">Tab content 1</div>
      <div *ngIf="displayDiv2">Tab content 2</div>
      <div *ngIf="displayDiv3">Tab content 3</div>
</div>
