大家好,
下面是我的部分代码
开始代码protected void Button1_Click(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "temp", "<script>loadAdditionalInfoDialog(info1)</script>",false);
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "temp2", "<script>loadAdditionalInfoDialog(info2)</script>",false);
}
代码结束 loadAdditionalInfoDialog()
函数会提示一个小窗口,让用户输入一些信息,然后点击"ok";
但是,当我点击Button1,我只能看到第二个RegisterStartupScript
,这是loadAdditionalInfoDialog(info2)
的工作,它会提示小窗口,我可以输入一些信息,点击"OK"
因此,我不能为第一个RegisterStartupScript
输入信息,即loadAdditionalInfoDialog(info1)
。
我想问的解决方案是,当我点击Button1,我可以先输入信息为loadAdditionalInfoDialog(info1)
,然后点击"OK"按钮,然后继续输入loadAdditionalInfoDialog(info2)
的信息。
万分感谢。
实际上Button1_Click只是一个按钮,我创建做测试。事实上,我只会调用loadAdditionalInfoDialog()当我在中继器中获得数据:
protected void btnRedeemAll_Click(object sender, EventArgs e)
{
foreach( RepeaterItem itm in repGiftResults.Items )
{
/*
code to get all those parameter
*/
if (pr.AdditionalFieldsEnabled == true)
{
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "temp", "<script>loadAdditionalInfoDialog(1," + pr.ID + "," + giftId + ",'" + txtQty.ClientID + "'," + tokenId + ")</script>", false);
}
}
}
因此,我认为这是我很难调用第二次loadAdditonalInfoDialog()当我点击"OK"按钮,因为我需要在中继器中获得许多参数。
好吧,你的代码应该工作得很好,只要确保你的info1和info2定义和修改你的loadAdditionalInfoDialog的逻辑。只是为了测试,在里面放一个警报。你也可以在一个代码块中调用这两个函数。
更新:这是我从你的评论中理解你想做的:
在重复器模板中添加一个隐藏字段
<asp:HiddenField ID="hdf" runat="server" />
在后面的代码中,你可以尝试这样做
foreach (RepeaterItem item in cdcatalog.Items)
{
// Put your condition here like if (pr.AdditionalFieldsEnabled == true) in my case to make it simple I'm just using the index
if (item.ItemIndex == 1)
{
//Get the hidden fiels to save your parameters for the next call you can add multiple parameters 1;2;3;4 and read it using js
HiddenField hdf = item.FindControl("hdf") as HiddenField;
hdf.Value = "info2";
// Pass the client ID for the hidden field so you can access it in loadAdditionalInfoDialog to retrieve parameter
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), String.Format("temp_{0}",item.ItemIndex),
String.Format("<script>loadAdditionalInfoDialog('info1',{0});</script>",hdf.ClientID),
false);
}
}
,在你的脚本中你可以这样做:
<script type="text/javascript">
function loadAdditionalInfoDialog(param, hdfId) {
// Do whatever yout want here
var info = prompt("Please enter ", param);
if (info != null) {
// Do whatever you want with the info you collected
// This code should be in your ok click button to check whether you should call the second window.
if (info !== undefined) {
loadAdditionalInfoDialog(hdfId.value);
}
}
}
</script>
我希望这对你有帮助
如果您还在寻找这样做的方法。这就是我的工作,在你的例子中实现:
protected void Button1_Click(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "temp", " <script>loadAdditionalInfoDialog(info1); loadAdditionalInfoDialog(info2); </script>",false);
}
我将两个过程合并为一个,如果你需要先做一个,然后再做第二个,它可能会有帮助
