我正在寻找在我的角度4应用程序中切换三个div。我基本上有以下三个div 收入证明 现金流量表 资产负债表
如果您注意到ul-li标签内的锚标签。单击锚标记应显示相应的div。我已经将href设置为href =“javascript：void（0）;并且尝试基于showTable变量进行切换，默认情况下，该变量在组件代码上设置为true。由于某种原因它不起作用。有人能告诉我我怎么能去实现它
<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"

如果您想根据锚点击和切换显示div，请按以下步骤操作。
displayDivNumber:number;
onAnchorClick(no) {
this.displayDivNumber = no;
}
html with ngSwitch
<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，那么您应该尝试通过为每个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>
