整理文档，搜刮出一个vue事件对象、冒泡、阻止默认行为的代码，稍微整理精简一下做下分享。
事件对象
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script src="https://www.jb51.net/js/Vue.js" charset="utf-8"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', data:{}, methods:{ show:function(ev){ alert(ev.clientX); alert(ev.clientY); } } }); } </script> </head> <body> <div> <input type="button" value="按钮" @click="show($event)"> </div> </body> </html>
事件冒泡
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script src="https://www.jb51.net/js/Vue.js" charset="utf-8"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', data:{}, methods:{ show:function(){ alert(111); //原生的写法 //ev.cancelBubble = true; }, show2:function(){ alert(222); } } }); } </script> </head> <body> <div> <div @click="show2()"> <input type="button" value="按钮" @click.stop="show()"> </div> </div> </body> </html>
阻止事件默认行为
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <style> .show2{ padding:15px;; } </style> <script src="https://www.jb51.net/js/Vue.js" charset="utf-8"></script> <script type="text/javascript"> window.onload = function () { var vm = new Vue({ el: '#box', data: {}, methods: { show: function () { alert(111) }, show2: function () { alert(222) } } }); } </script> </head> <body> <div> <div> <input type="button" value="按钮" @contextmenu.prevent="show()"> </div> </div> </body> </html>
