Question

如果有按钮，我想在点击时从组件中动态添加.//*[contains(@name,'Category One')] style="overflow:hidden"。点击此body <a>即可，此时应将isWriteEmail添加到正文

overflow:hidden

尝试了这个 <a href="javascript:void(0)" class="mail-ac-ico" (click)="appComponent.isWriteEmail = true;" data-toggle="tooltip" tooltip="Compose" title="Compose"> <img src="assets/images/icons/icon-open-email.png" alt="email icon"> </a>无效

Answer 1

你必须创建一个类：

.overflowHidden {
    overflow: hidden
}

然后，在模板中：

<a href="javascript:void(0)"
    class="mail-ac-ico"
    (click)="appComponent.isWriteEmail = true;"
    [class.overflowHidden]="appComponent.isWriteEmail"
    data-toggle="tooltip"
    tooltip="Compose"
    title="Compose">
    <img src="assets/images/icons/icon-open-email.png" alt="email icon">
</a>

如何动态地从组件添加样式到body
