需要javascript代码来确认删除按钮删除 [英] need javascript code to confirm deletion by buttonfield delete

问题描述

你好

我是新来的，这是我的第一个问题。我有一个带按钮字段删除的gridview。它工作正常。我想使用javascript代码添加一个确认框。我不能使用onclientclick因为我不使用templatefield.please帮助。

解决方案

hi，

在这种情况下你需要在gridview / listview ItemDataBound事件上注册确认脚本。

参考这些链接将解决你的问题。

ASP.NET GridView删除确认使用asp：CommandField [ ^ ]

http://highoncoding.com/Articles/138_GridView_Confirm_When_Delete.aspx [ ^ ]

< blockquote>这是最简单的方法： http://www.w3schools.com/jsref/met_win_confirm.asp [ ^ ]。



或者，您可以使用jQuery创建精彩且非常灵活的确认对话框。看看：

如果您需要学习jQuery（强烈推荐），请参阅：

http ：//en.wikipedia.org/wiki/JQuery [ ^ ]，

http://jquery.com/ [ ^ ]，

http ：//learn.jquery.com/ [ ^ ]，

关于onclienclick的问题看起来与我无关，我甚至无法理解你的想法。无论如何，您需要在客户端获得确认。您不必使用后面的ASP.NET代码来添加事件处理程序，生成一些HTML，它可以包含任何JavaScript。

解决方案

hi,
in such cases you need to register the confirmation script on gridview/listview ItemDataBound Event.
Refer to these links will solve your problem.
ASP.NET GridView delete confirmation using asp:CommandField[^]
http://highoncoding.com/Articles/138_GridView_Confirm_When_Delete.aspx[^]

This is the simplest possible way: http://www.w3schools.com/jsref/met_win_confirm.asp[^].

Alternatively, you can create wonderful and very flexible confirmation dialogs using jQuery. Check it out:
http://myclabs.github.io/jquery.confirm/[^].

If you need to learn jQuery (highly recommended), please see:
http://en.wikipedia.org/wiki/JQuery[^],
http://jquery.com/[^],
http://learn.jquery.com/[^],
http://learn.jquery.com/using-jquery-core/[^],
http://learn.jquery.com/about-jquery/how-jquery-works/[^] (start from here).

Your question about "onclienclick" looks irrelevant to me, I cannot even understand your idea. You need to get confirmation on the client side anyway. You don't have to use ASP.NET code behind to add an event handler, you generate some HTML, and it can contain any JavaScript.

[EDIT]

In response to the OP's comment to this answers:

The answer is in this comment. Note that his event can be cancelled:

<asp:imagebutton id="ImageButton1" runat="server">
             ImageUrl ="~/images/grdbtndelete.png" CommandName ="Delete" 
OnClientClick="return confirm("Are you sure you want to delete this entry?");"  />
</asp:imagebutton>
