v-on
可以用v-on指令监听DOM事件，并在触发时运行一些JavaScript代码
<!DOCTYPE html>
<html xmlns:v-on="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>事件</title>
</head>
<body>
<div id="app">
<button v-on:click="tips">点击我</button>
</div>
<!--导入Vue.js-->
<script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.min.js"></script>
<script>
var vm=new Vue({
el: "#app",
data: {
message: '请关闭提示框'
},
methods: {
//方法必须定义在Vue的Methods对象中
tips: function (event) {
alert(this.message);
}
}
});
</script>
</body>
</html>
