1、绑定监听@click:
(以监听click为例,其他如keyup,用法类似) v-on:click="fun"
@click="fun"
@click="fun(参数)"
<button @click="test1">test1</button> <button @click="test2(‘abc‘)">test2</button> <button @click="test3(‘abcd‘, $event)">test3</button> methods: { test1(eve) {//test1函数没有参数,默认传递 $event alert(eve.target.innerHTML) //test1 }, test2 (msg) { //test1函数有参数,传递该参数 alert(msg) // abc }, test3 (msg, event) { //有参数,如果想获取到enevt,则函数中需要写 $event alert(msg+‘---‘+event.target.textContent) // abcd---test3 } }
2、@click.stop与@click.prevent
@click.stop 阻止事件冒泡
<div id="app"> <div v-on:click="dodo"> <button v-on:click="doThis">阻止单击事件继续传播</button> </div> </div> <script> var app = new Vue({ el: "#app", data: { name: "Vue.js" }, methods: { doThis: function () { alert("noclick"); }, dodo: function () { alert("dodo"); } } }); </script>//将会先弹出“noclick”,再弹出“dodo”。
<div id="app"> <div v-on:click="dodo"> <button v-on:click.stop="doThis">阻止单击事件继续传播</button> </div> </div> <script> var app = new Vue({ el: "#app", data: { name: "Vue.js" }, methods: { doThis: function () { alert("noclick"); }, dodo: function () { alert("dodo"); } } }); </script>//只弹出“noclick”
@click.prevent 阻止事件的默认行为,
<a href="http://www.baidu.com" @click.prevent="test4">百度一下</a> //阻止a标签跳转,仅执行函数test4 <form action="/xxx" @submit.prevent="test5"> //阻止表单提交,仅执行函数test5 <input type="submit" value="注册"> </form>
3、按键修饰符
@keyup.enter
//按下enter时,执行方法test7 <input type="text" @keyup.enter="test7"> methods: { test7 (event) { console.log(event.keyCode) alert(event.target.value) } }
