this.$emit("click")

但是,像上面这种写法太麻烦,有时候就想在child(原生组件)监听,可以加上.native:

<script src="./vue.js"></script>
<!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
</head>
<body>
<div id="root">
//加了.native可以触发handleClick <br>
<child @click.native="handleClick"></child>
//不加.native无法触发handleClick <br>
<child @click="handleClick"></child>
</div>
<script type="text/javascript">
Vue.component("child", {
//这里绑定的事件是指的原生的事件
template: "<div>I am a child</div>",
});
var vm = new Vue({
el: "#root",
methods: {
handleClick: function() {
//此处不能触发<child @click="handleClick"></child>绑定的handleClick事件,因为这是自定义事件
alert("fatherClick");
}
}
})
