Submit the button name by hitting the enter key on IE6

I have a problem on IE6 only.

I have a page with several forms, each contains a textbox and a submit button. As I'm using .NET MVC, I need the name of the submit button to execute the correct Action. When I'm hitting 'Enter' key, I have the same behaviour as a clicked action on Firefox or Chrome (Field and ButtonName is sent), but not in IE6, where I have only the field that sent.

So how to send the name of the button when I'm hitting 'Enter' key on IE6 ?

tl/dr : I need to send in POST this

Field=foo&Search=

by clicking the 'Enter' key on IE6 and not only

Field=foo

Chrome and Firefox works well by clicking or hitting 'Enter'

Thanks for helping :)

[EDIT] Add an example:

Source code

   <!-- gestion type operation -->
<fieldset>
    <legend>Interface de gestion des Types d'Opérations</legend>
    <% Html.BeginForm("TypeOperation", "Administration", FormMethod.Post); %>
    <%= Html.EditorFor(m => m.TypeOperationField)%>
    <input type="submit" id="RechercheTypeOperation" name="RechercheTypeOperation" value=""
        class="loupe" />
    <% Html.RenderPartial("ListeTypeOperation", Model); %>
    <% Html.EndForm(); %>
</fieldset>
<!-- gestion type operation -->

It is pretty simple, this form struct is repeated each time I need a search textbox + submit button in page. Forms are well opened and closed when the code is generated.

Generated Code

    <!-- gestion type operation -->
<fieldset>
  <legend>Interface de gestion des Types d'Op&#233;rations</legend>
  <form action="/Administration/TypeOperation" id="form3"
  method="post">
    <input class="text-box single-line" id="TypeOperationField"
    name="TypeOperationField" type="text" value="" />
    <input type="submit" id="RechercheTypeOperation"
    name="RechercheTypeOperation" value="" class="loupe" />
    <div>
      <table class="grid">
        <thead>
          <tr>
            <th></th>
          </tr>
        </thead>
        <tbody>
          <tr>
            <td></td>
          </tr>
        </tbody>
      </table>
    </div>
  </form>
  <script type="text/javascript">//
<![CDATA[
if (!window.mvcClientValidationMetadata) { window.mvcClientValidationMetadata = []; }
window.mvcClientValidationMetadata.push({"Fields":[],"FormId":"form3","ReplaceValidationSummary":false});
//]]>
</script>
</fieldset>
<!-- gestion type operation -->

[EDIT 2] I have add this line inside my form

<!--[if IE]><input type="text" style="display: non开发者_StackOverflowe;" name="RechercheTypeOperation" value="" disabled="disabled" size="1" /><![endif]-->

And it's working.

I think, you shouldn't rely on the name of submit button, but rather create an <input type="hidden" with the name you want (like search).

There's really no difference between submit button name and the name of any other input field, except that submit input field is not really a field, so there always could be some artifacts with that.
