onmouseout的问题~

Question

把onmouseout="this.style.display='none';">这句删了

Answer 1

凑合用，哈  <div id="div1" style="display:none;width:100px;height:40px; background-color:Red;" onmouseout="this.style.display='none';">
        <a href="#" onmouseover="document.getElementById('div1').style.display = 'block';">abc</a>
    </div>
    <br />
    <br />
    <div>
        <a href="#" onclick="document.getElementById('div1').style.display = 'block';">123</a>
    </div>

Answer 2

改进，现在好多了  <div id="div1" style="display:none;width:100px;height:40px; background-color:Red;" onmouseout="this.style.display='none';" onmouseover="this.style.display='block';">
        <a href="#">abc</a>
    </div>
    <br />
    <br />
    <div>
        <a href="#" onclick="document.getElementById('div1').style.display = 'block';">123</a>
    </div>

onmouseout 与 onmouseover 基本上都是配对用的！
