onmouseover/out与div的问题
<div   id= "div1 "   onmouseover= "event1 "   onmouseover= "event2 ">
        <div   id= "div1_1 "> test </div>
        <div   id= "div1_2 "> demo </div>
</div>

我在外层div中加了onmouseover   onmouseout事件，在应用中发现鼠标一移到div1_1   div1_2上时，就会触发onmouseout，好像离开了div1,像这种情况要如何办？

------解决方案--------------------
用onmouseenter和onmouseleave 代替onmouseover和onmouseout
