子元素和父元素的点击事件只触发一个

 
    
         


function divone(){ 
    //这里是divone事件的代码 
    console.log('divone事件');
    stopPropagation();
} 
        
function divchild(){
    //这里是divchild事件的代码 
    console.log('divchild事件');
    stopPropagation();
}

function stopPropagation(e) {  
    e = e || window.event;  
    if(e.stopPropagation) { //W3C阻止冒泡方法  
        e.stopPropagation();  
    } else {  
        e.cancelBubble = true; //IE阻止冒泡方法  
    }  
}
