【中文标题】选中 Gridview 中的所有复选框【英文标题】：Select all Checkboxes in a Gridview 【发布时间】：2016-06-05 09:03:40 【问题描述】：我正在尝试选择我在页面上运行的 gridview 中的所有复选框，我正在使用 JQuery 和 javascript 作为函数，但 javascript 似乎不起作用。 我在普通表上尝试了相同的脚本并且它有效，但它似乎不适用于我添加到我的 gridview 的复选框。 你们能帮我解决这个问题吗？ 这是页面的代码。

【问题讨论】：
GridView 复选框使用 ajax 渲染？ 请显示你的结果html！ 问题出在你的html中，在渲染你的表格时，你可能在绘制表格时出现了混乱，显示你的结果html代码来帮助。 【参考方案1】：我创建了新项目并使用了您的代码。您的 JS 不工作的原因是因为您中继了服务器控件的 Id，例如：
#tblChck, #gvData
它们在客户端浏览器中会有不同的 ID。这就是 ASP.NET 防止 Id 重复的工作方式。如果您有一个母版页，则内容页中的所有 serwer 控件都将在 ID 中添加一个前缀，例如“MainContent_”。为了让您的 JS 工作，您需要将 JQ 选择器更改为 table[id*=tblChck] 之类的东西，或者您可以添加一个 css 类并通过它进行选择。
为了让您的代码能够正常工作，我必须将 JS 更改为：
<script type="text/javascript">
$(function ()
$("table[id*=tblChck] [id*=chkHeader]").click(function ()
if ($(this).is(":checked"))
$("table[id*=gvData] [id*=cbSelect2]").attr("checked", "checked");
else
$("table[id*=gvData] [id*=cbSelect2]").removeAttr("checked");
);
$("table[id*=gvData] [id*=cbSelect2]").click(function ()
if ($("table[id*=gvData] [id*=cbSelect2]").length == $("table[id*=gvData] [id*=cbSelect2]:checked").length)
$("table[id*=tblChck] [id*=chkHeader]").attr("checked", "checked");
else
$("table[id*=tblChck] [id*=chkHeader]").removeAttr("checked");
);
);
</script>
【讨论】：
我在master中引用了JQuery 但它似乎并没有干扰我在此页面中引用的脚本。我在普通静态表上尝试了相同的脚本引用相同的函数，它有效，它共享相同母版页。我已经在 Internet Explorer 上发布了渲染的 HTML 和控制台。感谢您的帮助 通过呈现的 html 我的意思是 html 源视图而不是浏览器屏幕；) 对不起，你能不能指定，因为这个特定页面的所有源代码都在问题中，我是否也应该发布母版页的代码。 @Rob 谢谢你的指导，我已经相应地更新了我的答案。【参考方案2】：$(document).ready(function()
$('.chkHeader').click(function(event)
if(this.checked) // check select status
$('.gridCB').each(function()
$('.chkHeader').each(function()
this.checked = true;
);
this.checked = true;
);
else
$('.gridCB').each(function()
$('.chkHeader').each(function()
this.checked = false;
);
this.checked = false;
);
);在 .chkHeader 主复选框中添加类 喜欢：->
<asp:CheckBox id="chkHeader" class="chkHeader" Text="Selecione Todos" runat="server" />
