整理文檔，搜刮出一個vue2.0的contextmenu右鍵彈出菜單的實例代碼，稍微整理精簡一下做下分享。
1.事情對象
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8"> <script src="http://unpkg.com/vue/dist/vue.js"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', methods:{ show:function(event){ console.log(event); //event 這個就是事件對象了 } } }); } </script></head><body> <div id="box"> <input type="button" value="按鈕" @click="show($event)"> </div></body></html>通過show($event)把事件對象傳到方法里
2.事件冒泡
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8"> <script src="http://unpkg.com/vue/dist/vue.js"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', methods:{ show:function(){ alert(1); }, show1:function(){ alert(2); } } }); } </script></head><body> <div id="box"> <div @click="show1()"> <input type="button" value="按鈕" @click="show()"> </div> </div></body></html>點擊按鈕的話他會，執行show ,show1方法，依次彈出1，2。
怎么來阻止
<1> 利用我們上面講過的event對象: event.cancelBubble = true; //這種就阻止了
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8"> <script src="http://unpkg.com/vue/dist/vue.js"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', methods:{ show:function(event){ alert(1); event.cancelBubble = true; }, show1:function(){ alert(2); } } }); } </script></head><body> <div id="box"> <div @click="show1()"> <input type="button" value="按鈕" @click="show($event)"> </div> </div></body></html><2>利用vue的方法阻止冒泡：給HTML元素綁定click事件的時候，改為@click.stop="show()"
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8"> <script src="http://unpkg.com/vue/dist/vue.js"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', methods:{ show:function(event){ alert(1); //event.cancelBubble = true; }, show1:function(){ alert(2); } } }); } </script></head><body> <div id="box"> <div @click="show1()"> <input type="button" value="按鈕" @click.stop="show()"> </div> </div></body></html>3.默認行為
比如contextmenu右鍵菜單
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8"> <!-- // <script src="vue.js"></script> --> <script src="http://unpkg.com/vue/dist/vue.js"></script> <script type="text/javascript"> window.onload = function(){ var vm = new Vue({ el:'#box', methods:{ show:function(){ alert(1); }, show1:function(){ alert(2); } } }); } </script></head><body> <div id="box"> <input type="button" value="按鈕" @contextmenu="show()"> <input type="button" value="按鈕1" @contextmenu.prevent="show1()"> <p>//按鈕右擊點下去會依次出現 彈窗 1， 還有右擊的默認菜單</p> <p>//按鈕1右擊只出現 彈窗 2</p> </div></body></html>以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
