问题
On my master page I have:
<form id="ReportForm" action="HelpAsk.aspx" method="post">
<input type="hidden" id="HiddenReport" type="text" />
</form>
This is outside any server tags, just before the tag.
Jquery submits this form when a button on the page is clicked somewhere:
function SendReport() {
$("#HiddenReport").val("<html>" + $("html").html() + "</html>");
$('#ReportForm').submit();
}
But whatever I try, I can't get my receiving page to read that data:
NameValueCollection nvc = Request.Form;
if (!string.IsNullOrEmpty(nvc["HiddenReport"]))
{
Response.Write("LOL:" + Request.Form["HiddenReport"]);
}
回答1:
You need to give the input element a name attribute to have it posted with the form submit, e.g.
<input type="hidden" id="HiddenReport" name="HiddenReport" />
Also you have two type attributes, remove one of these.
回答2:
you need to add name attribute
<input type="hidden" id="HiddenReport" name="HidenReport" type="text" />
name use as key in posted form
