&与&amp 转换问题 刚才说的不清楚结了换这张继续
pagelist.Attributes.Add("onchange", "self.location.href='userlist.aspx?page='+this.options[this.selectedIndex].value+" + "'&selKind =" + sKind + "&txtKey =" + sKey + "&isSearch=" + isSearch+"'");

在源码的显示成
<select name="pagelist" id="pagelist" class="minbox" onchange="self.location.href='userlist.aspx?page='+this.options[this.selectedIndex].value+'&selKind =&txtKey =&isSearch='" style="margin-top:6px;width:60px;">

为什么&变成了&amp 怎么解决

& 前加 "\"

没关系的，不影响使用

改成：

pagelist.Attributes.Add("onchange", "self.location.href= 'userlist.aspx?page= "+this.options[this.selectedIndex].value+"&selKind =" + sKind + "&txtKey =" + sKey + "&isSearch=" + isSearch+"'");
[解决办法]
改成下，最好不要多出空格：
pagelist.Attributes.Add("onchange", "self.location.href= 'userlist.aspx?page= '"+this.options[this.selectedIndex].value+"'&selKind=" + sKind + "&txtKey=" + sKey + "&isSearch=" + isSearch+"'");
