两个div叠加触发事件发生闪烁问题_html/css_WEB-ITnose

Jun 24, 2016 am 11:18 AM

今天遇到一个问题,想实现一个功能:

当鼠标移到div1上的时候,会出现div2。出现时div2在div1的上面,div2在出现后发生闪烁的问题。

于是开始找问题根源,发现原来是因为当我们触发div1的时候,div2出现,但是div2是存在于div1上面的,所以当div2出现后,会又一次触发下面div1的事件。通常我们可能给的事件是mouseover和mouseout,因为两个div叠加,div2出现时会多次触发div1的事件,所以就会发生闪烁问题。

解决:

1.一开始换mouseenter和mouseleave,但是发现还是一样的问题。

注:

mouseover()与mouseout()   表示鼠标移入和移出的时候触发,穿过子元素也会触发

 

mouseenter()和mouseleave()   表示鼠标穿过和穿出时候触发,穿过子元素不会触发

 

2.然后又添加e.stopPropagation();阻止冒泡和e.preventDefault();阻止默认事件,还是没有对症。

注:

e.stopPropagation();   //阻止冒泡之后,就不会形成冒泡向上传递了。

 

e.preventDefault();    //阻止默认行为

3.最后换为切换事件toggle切换事件也不顶事儿。

4.最终,如果想用js解决这个问题可能不容易,用js基本都会发生闪烁问题。那么我们使用css方式是不是可以解决呢?网上查了很多资料,发现也有很多人遇到这个问题,使用的是css中的hover来解决的。

具体使用方法:

给两个div的父元素,也就是共同包裹两个div的盒子一个hover,当父元素hover时,div2的样式设置为display:block;于是就顺利解决了这个问题,不会再出现闪烁问题。

下面上代码:

html部分:

 

<div class="fudiv">        <span class="div1"><img src="/static/imghw/default1.png"  data-src="img/jixinjia-partner1.jpg"  class="lazy" alt=""/></span>        <div class="div2">                 <div class="box6"><img src="/static/imghw/default1.png"  data-src="img/qr-code-bg1%20(1).jpg"  class="lazy" alt="p"/></div>                 <p>扫码有奖</p>        </div></div>
Copy after login

css部分:

.fudiv:hover .div2 {         display: block;}.div2{          display: none;}
Copy after login

原本jquery部分,这种方式会出现闪烁问题

<script>    $(document).ready(            function(){                $(".div1").mouseover(                        function(e){                            e.stopPropagation();                            $(".div2").show();                        }                );                $(".div1").mouseout(                        function(e){                            e.stopPropagation();                            $(".div2").toggle();                        }                );            }    );</script>
Copy after login
