1.使用keydown触发事件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <style>

    </style>
    <script src="vue.js"></script>
    <script>
        window.onload=function(){
            new Vue({
                el:'#box',
                data:{

                },
                methods:{
                    show:function(){
                        alert(1);
                    }
                }
            });
        };
    </script>
</head>
<body>
    <div id="box">
        <input type="text" @keydown="show">
    </div>
</body>
</html>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <style>

    </style>
    <script src="vue.js"></script>
    <script>
        window.onload=function(){
            new Vue({
                el:'#box',
                data:{

                },
                methods:{
                    show:function(ev){
                        alert(ev.keyCode);
                    }
                }
            });
        };
    </script>
</head>
<body>
    <div id="box">
        <input type="text" @keydown="show($event)">
    </div>
</body>
</html>

3.keyup事件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <style>

    </style>
    <script src="vue.js"></script>
    <script>
        window.onload=function(){
            new Vue({
                el:'#box',
                data:{

                },
                methods:{
                    show:function(ev){
                        alert(ev.keyCode);
                    }
                }
            });
        };
    </script>
</head>
<body>
    <div id="box">
        <input type="text" @keyup="show($event)">
    </div>
</body>
</html>

4.Vue中在键盘事件后面添加键码值就可以说明是按下了哪个键

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>智能社——http://www.zhinengshe.com</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <style>

    </style>
    <script src="vue.js"></script>
    <script>
        window.onload=function(){
            new Vue({
                el:'#box',
                data:{

                },
                methods:{
                    show:function(){
                        alert('您按回车了');
                    }
                }
            });
        };
    </script>
</head>
<body>
    <div id="box">
        <input type="text" @keyup.13="show()">
    </div>
</body>
</html>

4.使用键名enter

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <style>

    </style>
    <script src="vue.js"></script>
    <script>
        window.onload=function(){
            new Vue({
                el:'#box',
                data:{

                },
                methods:{
                    show:function(){
                        alert('您按回车了');
                    }
                }
            });
        };
    </script>
</head>
<body>
    <div id="box">
        <input type="text" @keyup.enter="show()">
    </div>
</body>
</html>

5.使用键名left

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <style>

    </style>
    <script src="vue.js"></script>
    <script>
        window.onload=function(){
            new Vue({
                el:'#box',
                data:{

                },
                methods:{
                    show:function(){
                        alert(1);
                    }
                }
            });
        };
    </script>
</head>
<body>
    <div id="box">
        <input type="text" @keyup.left="show()">
    </div>
</body>
</html>
