//上面是从数据读取数据
//下面是输出div
echo "

";
echo "B: ".$row["b"];
?>
<script> <br />function pop(w){ <br /> <br />alert(w.value); <br />} <br /></script>

//为什么会undefine?????
//谢谢!!


回复讨论(解决方案)

alert(w.id) 就可以,w.value就不行。。。。是上面原因呢?

试试 w.getAttribute("value") 看看

.value属性是对于input来说的,你用div肯定不行,如果是 w.getAttribute("value")应该可以得到div的value。

改这样就可以了。

<?php$row['xxx'] = 100;$row['b'] = 1;echo "<div id='b' class='opdiv'  value='".$row['xxx']."'   onclick='pop(this)'>click</div>";echo "B: ".$row["b"];?><script>function pop(w){    alert(w.getAttribute('value'));    //alert(w.value);}</script>

谢谢上面各位老大!

各位老大,如何继续通过js 把 当前的div 隐藏起来呢???谢谢!
