锚点问题!
因为有需要，要把页面中的一些字符提取出来，用于替换。
可以下面的例子中，对于锚点却存在问题，不能链接到锚点上去，如果不执行window.onload里的代码却可以链过去。但window.onload里的代码是正确的，确实确实替换了。。想不通？？？


把以下文件保存为test.htm:

<TITLE> || <$WebName$>   <$WebURLDomain$> </TITLE>
<script>
var   o_navigator   =   navigator.userAgent;
var   isIE   =   (o_navigator.indexOf( "MSIE ")   >   -1)   ?   true   :   false;
var   req;
var   CharDefineValue   =   " ";
var   re=/[\W]/g;

var   myJSONDefine   =   [
{
OptionType: "CharacterDefine ",
OptionCode: "WebName ",
MasterValue: "无线网站 ",
SlaveValue: " ",
OtherValue: " ",
Remark: "定义网站名称 "
},
{
