Tel：028-86922220 我有需求

    
    
    

    
        window.onload = function(){            var vm = new Vue({
                el:'#box',
                methods:{
                    show:function(event){
                        console.log(event);   //event   这个就是事件对象了                    }
                }
            });
        }    
   
         
    

    
    
    

    
        window.onload = function(){            var vm = new Vue({
                el:'#box',
                methods:{
                    show:function(){
                        alert(1);
                    },
                    show1:function(){
                        alert(2);
                    }
                }
            });
        }    
    
        
             
        

点击按钮的话他会，执行show ,show1方法，依次弹出1，2。

怎么来阻止

<1> 利用我们上面讲过的event对象:  event.cancelBubble = true;   //这种就阻止了

    
    
    

    
        window.onload = function(){            var vm = new Vue({
                el:'#box',
                methods:{
                    show:function(event){
                        alert(1);
                        event.cancelBubble = true;
                    },
                    show1:function(){
                        alert(2);
                    }
                }
            });
        }    
   
        
             
        
    

<2>利用vue的方法阻止冒泡：给HTML元素绑定click事件的时候，改为@click.stop="show()"

    
    
    

    
        window.onload = function(){            var vm = new Vue({
                el:'#box',
                methods:{
                    show:function(event){
                        alert(1);                        //event.cancelBubble = true;                    },
                    show1:function(){
                        alert(2);
                    }
                }
            });
        }    
    
        
             
        
    

3.默认行为

比如contextmenu右键菜单

    
    
    
    

    
        window.onload = function(){            var vm = new Vue({
                el:'#box',
                methods:{
                    show:function(){
                        alert(1);
                    },
                    show1:function(){
                        alert(2);
                    }
                }
            });
        }    
    
         
         

        
//按钮右击点下去会依次出现 弹窗 1， 还有右击的默认菜单
        
//按钮1右击只出现 弹窗 2
    

@click.stop.prevent，相当于同时执行：
event.stopPropagation();
event.preventDefault();
