Hi,

I'm using Master pages in my application,
and the design of masterpage is like below:

XML

<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>

my content page is loading in to "Contentplaceholder1".
Now what I want is how to check the status of all the checkboxes in a page in javascript.

I have tried like this
for(i=0; i<document.formName.elements.length; i++){

but no use (i'm unable to get form name in the loop)

Please help me.

thanks & regards

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.
jQuery: Checkbox selector[^]
