angular 中*ngIf 和*ngSwitch判断语句
<div class="cnblogs_code"><pre><div style="text-align:center">
<h1><span style="color: rgba(0, 0, 0, 1)">
Welcome to {{ title }}</span>!
</h1>
<p *ngIf="true">show</p>
<p *ngIf="isShow">hide</p>
<p template="ngIf true">这是 ngIF 判断是否显示</p>
<ul ="status">
<li *ngSwitchCase="1">已支付</li>
<li *ngSwitchCase="2">订单已经确认</li>
<li *ngSwitchCase="3">已发货</li>
<li *ngSwitchDefault>无效</li>
</ul>
