一 vue方法实现
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Vue方法与事件</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div id="test">
<button @click="sayHi">点击我</button> <!--这里使用@-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el: '#test',
methods: { //这里使用methods
sayHi: function () {
alert('我被点击了')
}
}
})
</script>
</body>
</html>
二 方法传参
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Vue方法与事件</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div id="test">
<button @click="sayHi('你好')">说你好</button> <!--这里使用@-->
<button @click="sayHi('我被点击了')">说我被点击了</button> <!--这里使用@-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el: '#test',
methods: { //这里使用methods
sayHi: function (message) {
alert(message)
}
}
})
</script>
</body>
</html>
三 vue访问原生 DOM 事件
注意用$event获取
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Vue方法与事件</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div id="test">
<button @click="changeColor('你好',$event)">点击我</button> <!--这里使用@-->
<div style="height: 100px;width: 100px;background-color: red;" @mouseover="over('鼠标从我上面滑过',$event)">
鼠标从我上面滑过试试
</div>
</div>
<script type="text/javascript">
var myVue = new Vue({
el: '#test',
methods: { //这里使用methods
changeColor: function (message, event) {
alert(message+event); //弹出我被点击了,事件是[object MouseEvent]
},
over :function (message, event) {
alert(message+event); //弹出鼠标从我上面滑过,事件是[object MouseEvent]
}
}
})
</script>
</body>
</html>
四 事件修饰符
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Vue方法与事件</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div id="test">
<button @click.stop="sayHi('你好')">说你好</button> <!-- 阻止单击事件冒泡 -->
<button @click.prevent="sayHi('你好')">说你好</button> <!-- 提交事件不再重载页面 -->
<button @click.stop.prevent="sayHi('你好')">说你好</button> <!-- 阻止单击事件冒泡和提交事件不再重载页面 -->
<button @click.capture="sayHi('你好')">说你好</button> <!-- 添加事件侦听器时使用 capture 模式 -->
<button @click.self="sayHi('你好')">说你好</button> <!-- 只当事件在该元素本身（而不是子元素）触发时触发回调 -->
<div @keyup.13="sayHi('你好')">说你好</div> <!-- 只有在 keyCode 是 13 时调用 vm.submit() -->
</div>
<script type="text/javascript">
var myVue = new Vue({
el: '#test',
methods: { //这里使用methods
sayHi: function (message) {
alert(message)
}
}
})
</script>
</body>
</html>
