I'm not sure I quite understand the context, but given a HiddenField:
我不确定我是否完全理解上下文，但给出了一个HiddenField：
<asp:HiddenField ID="hf_myhiddenfield" runat="server" Value="hidden value"/>
You can use a Javascript function to insert the value into your onclickattribute
您可以使用 Javascript 函数将值插入到您的onclick属性中
onclick
点击
onclick="window.open('../New/FeedbackV4.aspx'+GetHFValue(),'FeedbackWindow','width=960,height=640,scrollbars=yes,resizable=yes,status=yes')"
Javascript
Javascript
<script type="text/javascript">
function GetHFValue() {
var hf_value = '?' + document.getElementById("<%= hf_myhiddenfield.ClientID %>").value;
return hf_value;
}
</script>
回答by Jukka K. Korpela
Assuming for simplicity that the hidden field has an idattribute, say id='foo'(if not, you will need to find another way of picking up that element), use
为简单起见，假设隐藏字段具有id属性，例如id='foo'（如果没有，您将需要找到另一种获取该元素的方法），使用
onclick="window.open('../New/FeedbackV4.aspx?' + par('foo'), ..."
(note the added “?”)
（注意添加的“？”）
with
和
<script>
function par(elid) {
var elem = document.getElementById(elid);
return encodeURI(elem.name) + '=' + encodeURI(elem.value);
}
</script>
