Hi Expert!
I want to check condition before post my page on button click in MVC 4 using JavaScript or JQuery. My Code as below
@using (Html.BeginForm("AttachmentList", "Home", FormMethod.Post, new
{
@id = "PDFListDownload"
}))
{
<div id="PDFAttachmentList">
<table>
@foreach (var item in Model)
{
<tr>
<td>@Html.CheckBox("fileItem")
@Html.Hidden("fileId", item.AtttachmentID)
</td>
<td>@Html.DisplayTextFor(m => item.Description)
</td>
</tr>
}
<tr>
<td>
<input id="btnDownload" type="submit" value="Download" />
</td>
<td>
<input id="btnCancel" type="button" value="Cancel" onclick="CloseDialog();" />
</td>
</tr>
</table>
</div>
}
How it I do? Please help me?
Thanks in advance

I think, you want to force user to select at least one checkbox checked before post page according your code, if I'm right than you can try below line of code
<script type="text/javascript"> $(document).ready(function () { $('#btnDownload').live("click", function () { var checked = $("#PDFAttachmentList input:checked").length > 0; if (!checked) { alert("Please check at least one checkbox"); return false; } else { return true; } }); });
