1、$event 变量
$event 变量用于访问原生DOM事件。
<!DOCTYPE html> <html lang="zh"> <head> <meta charset="UTF-8" /> <title>vue示例</title> </head> <body> <div id="app"> 点击次数：{{counter}} <button @click="handleAdd(1,$evert)">+1</button> <button @click="handleAdd(10,$evert)">+10</button> </div> <script src="https://cdn.bootcss.com/vue/2.5.9/vue.min.js"></script> <script type="text/javascript"> var app = new Vue({ el: ‘#app‘, data: { counter: 0 }, methods: { handleAdd: function(counter, event) { //阻止默认事件 event.preventDefault(); counter = counter || 1; this.counter += counter; } } }); </script> </body> </html>
2、修饰符
<!--阻止事件冒泡-->
<a @click.stop="handle()"></a>
<!--阻止默认事件-->
<a @click.prevent="handle()"></a>
<!--修饰符可以串联-->
<a @click.prevent.stop="handle()"></a>
<!--只有事件本身（而非子元素）触发-->
<a @click.self="handle()"></a>
<!--只触发一次，组件同样适用-->
<a @click.once="handle()"></a>
<!--键盘事件-->
<a @keyup.enter="handle()"></a>
例子：
<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="UTF-8" />
<title>vue示例</title>
</head>
<body>
<div id="app">
<!--阻止默认事件-->
<a @click.prevent="handle()" href="https://www.baidu.com/">https://www.baidu.com/</a>
</div>
<script src="https://cdn.bootcss.com/vue/2.5.9/vue.min.js"></script>
<script type="text/javascript">
var app = new Vue({
el: ‘#app‘,
data: {
counter: 0
},
methods: {
handle: function() {
console.log(1111)
}
}
});
</script>
</body>
</html>
