检查是否至少选中了一个复选框 [英] Checking if at least one checkbox has been checked

问题描述

大家好。我需要JavaScript来验证在删除记录之前已在表单中检查了至少一个复选框。


- 我有一个< asp：button id =" btnDelete" ...>并通过grdData_ItemDataBound创建复选框，其中id =" chkRecordId"：

展开 | 选择 | Wrap < span class =codeDivider> | 行号

解决方案

< blockquote>由于复选框名为chkRecordId，您可以使用以下方法访问它们：

展开 | 选择 | Wrap | 行号

好​​的我会尝试一下。非常感谢。


对不起，我下次会这样做。新来的：P

顺便说一句，我可以使用：

展开 | 选择 | 换行 | 行号

Hi all. I need JavaScript to validate that atleast one checkbox has been checked in a form before the record(s) can be deleted.

- I have an <asp:button id="btnDelete"...> and the checkbox is created via grdData_ItemDataBound with id="chkRecordId":

Expand|Select|Wrap|Line Numbers

解决方案

Since the checkboxes are named "chkRecordId", you can access them using :

Expand|Select|Wrap|Line Numbers
