我在调试i
中的代码时说f2(i)
未定义。我做错了什么?
编辑:我从这个问题中学到了很多东西,但我仍然没有答案。我尝试了答案中给出的每个想法,但i
仍然是undefined
...
编辑:我仍然没有解决未定义的原因:),但我接受的答案通常是我的解决方案。

ClientScript.RegisterStartupScript
采用脚本定义,而非调用。
由于您想在外部定义该功能,请改为使用this method:
ClientScript.RegisterClientScriptBlock(this.GetType(), "RefreshOpener", "MyJavaScriptFile.js", true);
要在按钮单击时执行带有参数f2
的JavaScript函数Session["sayfaTuru"]
,请使用以下(未测试):
在Page_Load
中,添加包含f2
定义的JavaScript文件:
protected void Page_Load(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(...);
// Do other stuff
}
然后添加实际的按钮点击监听器,它将调用f2
:
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="f2(<%=Session['sayfaTuru']%>);" />

您是否尝试过调试服务器端代码以查看是否
int i = Convert.ToInt32(Session["sayfaTuru"]);
首先给你你想要的东西?
看看上面是如何检查的,我继续创建了我自己的测试,它工作得很好。这是我使用的测试:

<script type="text/javascript">
function f2(i, hiddenFieldId, updatePanelId) {
console.log(i + ', "' + hiddenFieldId + '", "' + updatePanelId + '"');
var hiddenField = window.opener.document.getElementById(hiddenFieldId);
switch (i) {
case 1: //CariKartHareketleri
hiddenField.value = "hello world 1";
window.opener.location.href = window.opener.location.href; //çağıran sayfayı yeniliyor
break;
case 2: //islemler
hiddenField.value = "hello world 2";
window.opener.__doPostBack('' + updatePanelId + '', '');
break;
case 3: //hizmet listesi
hiddenField.value = "hello world 3";
window.opener.__doPostBack('' + updatePanelId + '', '');
break;
default:
alert("error");
break;
}
}
</script>
<强> C#:强>
Session["sayfaTuru"] = 2; // initialize for testing purposes
int i = Convert.ToInt32(Session["sayfaTuru"]);
string script = string.Format("f2({0}, '{1}', '{2}');",
i.ToString(),
this.HiddenField1.ClientID,
this.GridRefreshPanel.UniqueID);
ClientScript.RegisterStartupScript(this.GetType(), "RefreshOpener", script, true);
console.log输出:
2, "HiddenField1", "GridRefreshPanel"
答案 2 :(得分:0)
我认为您可能会在代码隐藏中抛出异常。你试图连接字符串,但我是一个整数。试试这个:
int i = Convert.ToInt32(Session["sayfaTuru"]);
ClientScript.RegisterStartupScript(this.GetType(), "RefreshOpener", "f2(" + i.ToString() + ")", true);
虽然我实际上更喜欢使用String.Format:
int i = Convert.ToInt32(Session["sayfaTuru"]);
ClientScript.RegisterStartupScript(this.GetType(), "RefreshOpener", String.Format("f2({0})", i), true);
