Vue之阻止默认行为

1.使用原生js实现点击右键阻止默认行为

<!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(1);  
                        ev.preventDefault();  
                    }  
                }  
            });  
        };  
    </script>  
</head>  
<body>  
    <div id="box">  
        <input type="button" value="按钮" @contextmenu="show($event)">  
    </div>  
</body>  
</html>

描述：

使用原生js中的ev.preventDefault() 阻止默认行为

2.Vue中使用 .prevent 阻止默认行为

<!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="button" value="按钮" @contextmenu.prevent="show()">  
    </div>  
</body>  
</html>
