Adding javascript to a link's OnClientClick property while binding a repeater
提问by Juan Carlos Blanco Martínez
I'm trying to get this working but no success:
我试图让这个工作但没有成功：
<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="btnDeleteFamily_Click">
<HeaderTemplate>
<table>
<tr>
<th width="90" valign="top"><%=getTag("name")%></th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%#Eval("chrname")%></td>
<asp:LinkButton ID="btnDeleteFamily" CssClass="fRight ui-icon ui-icon-trash" runat="server" CommandName="delete" CommandArgument='<%#Eval("idmember")%>' OnClientClick='return confirm("<%= getTag("deletefamilymemberdialog") %>")' Text="" ValidationGroup="delete_family" />
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
When clicking on the btnDeleteFamily OnClientClick the confirm dialog is not shown.
单击 btnDeleteFamily OnClientClick 时，不会显示确认对话框。
getTag (method in the code behind) is used for localization to get the text depending on the language. My intention is to show that message in the JavaScript dialog, but I'm getting:
getTag（后面代码中的方法）用于本地化以根据语言获取文本。我的目的是在 JavaScript 对话框中显示该消息，但我得到：
<a href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$rptFamily$ctl01$btnDeleteFamily','')" class="fRight ui-icon ui-icon-trash" id="ctl00_ContentPlaceHolder1_rptFamily_ctl01_btnDeleteFamily" onclick='return confirm("<%= getTag("deletefamilymemberdialog") %>");'/>
So it's not processing getTag in the server side otherwise I would be getting
所以它不在服务器端处理 getTag 否则我会得到
onclick='return confirm("Are you sure that you want to delete this entry?");'
Thanks
谢谢

I think writing the message to page as a javascript variable is a better solution :
我认为将消息作为 javascript 变量写入页面是更好的解决方案：
<script>
var deleteMemberDialogMessage = '<%= getTag("deletefamilymemberdialog") %>';
</script>
And your repeater :
还有你的中继器：
<asp:LinkButton ID="btnDeleteFamily" CssClass="fRight ui-icon ui-icon-trash"
runat="server" CommandName="delete" CommandArgument='<%#Eval("idmember")%>'
OnClientClick='return confirm(deleteMemberDialogMessage)' Text=""
ValidationGroup="delete_family" />
By the way be sure that your deletefamilymemberdialog message doesn't have single quote.
顺便说一下，请确保您的 deletefamilymemberdialog 消息没有单引号。
EDIT :If you want to bind a value from your datasource to your repeater, you should bind your column to control instead of Response.Write (<%=) like that :
编辑：如果要将数据源中的值绑定到转发器，则应将列绑定到控件而不是像这样的 Response.Write (<%=) ：
<asp:LinkButton ID="btnDeleteFamily" CssClass="fRight ui-icon ui-icon-trash"
runat="server" CommandName="delete" CommandArgument='<%#Eval("idmember")%>'
OnClientClick='<%# Bind("return confirm('{0}');'", "YourColumnName") %> Text=""
ValidationGroup="delete_family" />

It seems to be ok, for me at least.
似乎没问题，至少对我来说。
You could try it in firefox, and using the WebDeveloper toolbar or Firebug extensions you will be able to get more information about what is happening behind scene.
您可以在 firefox 中尝试它，并使用 WebDeveloper 工具栏或 Firebug 扩展程序，您将能够获得有关幕后发生的事情的更多信息。
Maybe there are others errors on the page that doesn't allow this code to work.
也许页面上还有其他错误不允许此代码工作。

protected void Repeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lb = e.Item.FindControl("btnDelete") as LinkButton;
if (lb != mull) {
lb.OnClientClick = "whatever";
}
}

If you want to use the jQuery dialog in confirmation mode to bind to link buttons on a repeater inside an update panel, AND the code you want to execute after confirmation is different for each row, you can set it up this way:
如果您想在确认模式下使用 jQuery 对话框绑定到更新面板内中继器上的链接按钮，并且您要在确认后执行的代码对于每一行都不同，您可以这样设置：
Add a javascript function to your page/control like this:
向您的页面/控件添加一个 javascript 函数，如下所示：
function confirm(buttonFunctionForPostBack)
{
$("#dialog").dialog('option', 'buttons', {
"Cancel": function() {
$(this).dialog("close");
},
"Delete Payment": function () {
eval(buttonFunctionForPostBack);
$(this).dialog("close");
}
}
).dialog('open');
}
And in your code behind:
在你后面的代码中：
public void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lb = e.Item.FindControl("deleteButton") as LinkButton;
if (lb != null)
{
lb.OnClientClick = "confirm(\"" + this.Page.ClientScript.GetPostBackEventReference(lb, string.Empty) + "\");return false;";
}
}
And in your aspx page:
在您的 aspx 页面中：
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<HeaderTemplate>
<table>
<tr>
<th width="90" valign="top"></th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%#Eval("name")%></td>
<td><asp:LinkButton ID="deleteButton" runat="server" CommandName="delete" CommandArgument='<%#Eval("id")%>' Text="Delete" />
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
This lets you take advantage of the fact that you can set the dialog's 'buttons' option after the dialog was created. Also, it doesn't require any extra script variables.
这让您可以利用这样一个事实，即您可以在创建对话框后设置对话框的“按钮”选项。此外，它不需要任何额外的脚本变量。
