问题描述
我在应用程序中使用母版页，
母版页的设计如下:
Hi,
I''m using Master pages in my application,
and the design of masterpage is like below:
<body id="bodyHomePage" runat="server" class="style12" onkeypress="return eval((event.keyCode==13)?false:true);">
<form id="form1" runat="server" method="post" action="">
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager2" EnablePartialRendering="false" EnableViewState="true" LoadScriptsBeforeUI="false" runat="server"/>
<div>
<asp:UpdatePanel ID="updatePanelMaster" RenderMode="Block" runat="server"><ContentTemplate>
<table id="tdTable" runat="server" style="width:1240px;" cellspacing="0" cellpadding="0" align="center">
<tr>
<td id="main2" runat="server" valign="top" colspan="2">
<div id="main1" runat="server">
<uc2:WucTop ID="WucTop1" runat="server" />
</div>
</td>
</tr>
<tr>
<td id="left1" runat="server" valign="top">
<uc1:WucLeft ID="WucLeft1" runat="server" />
</td>
<td id="tdContent" runat="server" style="width:1050px" align="left" valign="top">
<table cellspacing="0" cellpadding="0" >
<tr>
<td valign="top" >
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</td>
</tr>
<tr>
<td valign="top" id="bottom1" runat="server">
<uc3:WucBottom ID="WucBottom" runat="server" />
</td>
</tr>
</table>
</td>
</tr>
</table>
</ContentTemplate></asp:UpdatePanel>
</div>
</form>
</body>
我的内容页面正在加载到"Contentplaceholder1".
现在我想要的是如何检查javascript页面中所有复选框的状态.
我已经尝试过了
for(i = 0; i< document.formName.elements.length; i ++){
但没有用(我无法在循环中获取表单名称)
请帮帮我.

看看类似的文章: http://www.sajithmr.me/check-all-checkboxes-javascript/ [ jQuery:复选框选择器 [ ^ ]
Have a look at similar article: http://www.sajithmr.me/check-all-checkboxes-javascript/[^]
All you need is to either loop through all the controls of the form and check for the type to move ahead
OR if you are fine with using jQuery then you can use jQuery to directly pick all the checkboxes and then you can move ahead.
