更改了值，但未触发更改事件。我想在更改ischecked时触发更改
在HTML
<input class="inputStyle" type="checkbox" [checked]="isChecked" id="actA" tabindex="0" (change)="onAct($event)">
还有其他功能（以ts为单位）
onChangeoption(lang) {
this.isChecked = true; `enter code here`
}
What you are trying to do is trigger a
changeevent after you have programatically changed the value of the input first and this is not going to work.我可以建议两种方法：
Approach 1: From what you have shown in those snippets, it seems easy to call
onActinside theonChangeoption. If you don't really need the change event object, you can callonActimmediately after you change the value ofisChecked.Approach 2: If you need the change event object, create a reference of the
inputelement and programatically dispatch achangeevent在您的TypeScript代码中：
