还是这个代码，VALUE值改成英文搜索模板的了。可每次搜素的时候只查找中文网站内的产品。为什么呢？
<script type="text/javascript">
function c_keyword()
{
if($("title").value=="")
{
alert("Please input keywords！");
$("title").focus();
return false;
}
}
</script>
<form method="get" action="/e/search/" target="zdy_search" name="S_article">
<input id="title" maxlength="50" size="15" name="title" type="text" /> <input type="hidden" name="modelid" value="135" /><input type="hidden" name="siteid" value="1" /><input class="button" type="submit" onclick="return c_keyword()" value=" Search " />
下面是我的搜素模型
<script language="C#" Runat="server">
private string SqlFormat(string str)
{
if(str=="" || str==null)
{
return "";
}
str=str.Replace("_","[_]");
str=str.Replace("%","[%]");
str=str.Replace("'","''");
str=str.Replace("\"","\"");
if(str.Length>20)
{
str=str.Substring(0,20); //截取前20个字符
}
return Server.HtmlEncode(str);
}
</script>
<script type="text/javascript">
function c_keyword()
{
if($("title").value=="")
{
alert("Please input the keywords！");
$("title").focus();
return false;
}
}
</script>
<form action="/e/search/" target="zdy_search" method="get" name="S_article">

</form>
<ul class="product_pic">

DataRow dr;
if(dt.Rows.Count>0)
{
%>
<li style="clear:both;float:none;height:30px;display:block;text-align:left;padding:0 0 0 0">Find <%=RecordCount%> product information records </li>
