vue-element-admin
在vue-element-admin中,directive是一种自定义指令的语法,通过全局注册自定义指令,可以在Vue组件中使用这些指令。一种常见的自定义指令是获取焦点指令,可以通过Vue.directive()方法来定义获取焦点的行为。在这个例子中,使用了一个名为'focus'的自定义指令,通过inserted钩子函数,在元素插入到DOM中时调用,实现了让元素获得焦点的功能。具体实现是通过el.children.focus()来将子元素设置为焦点。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
