一 vue方法實現
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Vue方法與事件</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">點擊我</button> <!--這里使用@--> </div> <script type="text/javascript"> var myVue = new Vue({ el: '#test', methods: { //這里使用methods sayHi: function () { alert('我被點擊了') } } }) </script> </body> </html>
二 方法傳參
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Vue方法與事件</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')">說你好</button> <!--這里使用@--> <button @click="sayHi('我被點擊了')">說我被點擊了</button> <!--這里使用@--> </div> <script type="text/javascript"> var myVue = new Vue({ el: '#test', methods: { //這里使用methods sayHi: function (message) { alert(message) } } }) </script> </body> </html>
三 vue訪問原生 DOM 事件
注意用$event獲取
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Vue方法與事件</title> <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" /> <script src="../js/vue.js" type="text/javascript" charset="utf-8"></script> </head> <body> <div id="test"> <button @click="changeColor('你好',$event)">點擊我</button> <!--這里使用@--> <div style="height: 100px;width: 100px;background-color: red;" @mouseover="over('鼠標從我上面滑過',$event)"> 鼠標從我上面滑過試試 </div> </div> <script type="text/javascript"> var myVue = new Vue({ el: '#test', methods: { //這里使用methods changeColor: function (message, event) { alert(message+event); //彈出我被點擊了,事件是[object MouseEvent] }, over :function (message, event) { alert(message+event); //彈出鼠標從我上面滑過,事件是[object MouseEvent] } } }) </script> </body> </html>
四 事件修飾符
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Vue方法與事件</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')">說你好</button> <!-- 阻止單擊事件冒泡 --> <button @click.prevent="sayHi('你好')">說你好</button> <!-- 提交事件不再重載頁面 --> <button @click.stop.prevent="sayHi('你好')">說你好</button> <!-- 阻止單擊事件冒泡和提交事件不再重載頁面 --> <button @click.capture="sayHi('你好')">說你好</button> <!-- 添加事件偵聽器時使用 capture 模式 --> <button @click.self="sayHi('你好')">說你好</button> <!-- 只當事件在該元素本身（而不是子元素）觸發時觸發回調 --> <div @keyup.13="sayHi('你好')">說你好</div> <!-- 只有在 keyCode 是 13 時調用 vm.submit() --> </div> <script type="text/javascript"> var myVue = new Vue({ el: '#test', methods: { //這里使用methods sayHi: function (message) { alert(message) } } }) </script> </body> </html>
