then assign all those DIVs with a class "100_20_" --- you give a very good advice, didn't think this way yet, thanks!

Once you know all those DIVs have class "100_20_", here's a very simple way to hide them all: $$('div.100_20_').invoke("hide");<html>
<head>
<script type="text/javascript" charset="utf-8" src="http://api.prototypejs.org/javascripts/prototype.js"></script>
</head>
<body>
<div id="100_20_1" class="100_20_">aaaaa</div>
<div id="100_20_234" class="100_20_">bbbbb</div>
<div id="100_20_44" class="100_20_">asfasfsa</div>
<script>
$$('div.100_20_').invoke("hide");
</script>
</body>
</html>

谢谢,不过我还是用了div id, --> getdocumentbytagname() ---> for loop to check string in id using indexof().. 这个还是简单...但在hide/show时, IE正常, FF不正常, 唉..

一种可能性是用computed style.The IE Syntax:
var myObject = document.getElementById("header");
var myStyle = myObject.currentStyle.backgroundColor;
The Firefox Syntax:
var myObject = document.getElementById("header");
var myComputedStyle = document.defaultView.getComputedStyle(myObject, null);
var myStyle = myComputedStyle.backgroundColor;

you just showed us why it's a good idea to use a mature javascript library

I tried it. The table on the page is a complex table, it has drag and drop, it has hide/show control, it shows the tree/branch/leaf structure. It works OK now on IE 8, but not IE 6, and not FF,The stuffs are hidden/shown successfully, but the whole table structure gets distorted....

看来你是能够得到id，只是不懂怎么hide。

I use style="display:none" or style="display:block" that should work in all browsers, right?.. what else? It works perfectly in IE. In FF, hide is ok, but when it shows again, the table doesn't show correctly..

看来你是真不知道。应该用style="display:none" 和 style="display:"

I tried that already, same result. The hide / show function works well in all browser types, except that in rows, if you don't hide them, every column is displayed, when you hide them and re-display them, some columns disappear..better show you example page here, but the website is blocked here...

I was just curious. The CSS2 standard for display property didn't say about empty string being a valid value.

这是我想到的最简单高效又不需要任何工具的方法，很多时候最笨的方法就是最好的假设id的范围是100_20_1 到 100_20_1000， 可以简单的用一个循环搞定，
try { document.getElementById('100_20_' + i).style.display='none' } catch{ ... }

document.getElementsByTagName("div")var divs = document.getElementsByTagName("div");
for (var i = 0; i < divs.length; i ++){
if (divs[i].id.indexof('100_20_') >= 0){
//Hide div
divs[i].style.display = ‘none';
}
}
