ASP.net C# can't read posted form element

2019-09-14 11:01发布

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.

you need to add name attribute

<input type="hidden" id="HiddenReport" name="HidenReport" type="text" />

name use as key in posted form
