在使用javascript或jquery提交表单时需要帮助

Question

I have a form which looks like this

@using (Html.BeginForm("ActionMethod","MyController FormMethod.Post)) {
 <button type="submit" value="Generate" name="action" class="button" id="btnGenerate">Generate Form</button>
 <button type="submit" value="Confirm" name="action" class="button" id="btnConfirm">Confirm</button>
}

and my javascript looks like this

 <script type="text/javascript">
     $(function () {

         var genOverlay = jQuery('<div id="overlay"><div class="innerblock box-shadow"><p>Please remember to print the registration form and sign both copies.</p><div><a id="btnClose" href="#" class="button">Close</a></div></div>');

         var confirmOverlay = jQuery('<div id="overlay"><div class="innerblock box-shadow"><p>Changes can not be made to this record once it has been confirmed. Are you sure you would like to confirm this form?</p><div> <a id="btnConfirmConfirmation" href="#" class="button">Confirm</a> <a id="btnCancel" href="#" class="button button-red">Cancel</a></div></div>');

         $('#btnGenerate').click(function () {
             genOverlay.appendTo(document.body);
             return false;
         });

         $('#btnConfirm').click(function () {
             confirmOverlay.appendTo(document.body);
             return false;
         });


         $('#btnConfirmConfirmation').live('click', function () {
             // Need help on submitting the form with the input button value of btnConfirm.

             // $('#btnConfirm').submit(); does not work
             // return true;
         });

         $('#btnClose').live('click', function () {
             genOverlay.remove();
         });

         $('#btnCancel').live('click', function () {
             confirmOverlay.remove();
         });
     });
</script>

How would i go about implementing btnConfirmConfirmation click on the overlay to just submit the form normally with the action value of "Confirm"?

Thanks for any help

Answer 1

The .submit() method only applies to <form> elements. You could add an id to your form:

<form id="myForm" ...>

Which, as you're using HtmlHelper to create it would be achieved with:

@using (Html.BeginForm("ActionMethod","MyController", FormMethod.Post, new { id = "myForm" })) { ...

And then call the submit method (documented here ) on that:

$('#btnConfirmConfirmation').live('click', function () {
    $('#myForm').submit();
});

Or you could go to the form for your button by finding the closest ancestor form element for the button:

$('#btnConfirmConfirmation').live('click', function () {
    $(this).closest('form').submit();
});

closest method is documented here .

Answer 2

submit is an event handler of the form element. This should work:

$('#btnConfirm')[0].form.submit()
//All form elements have a property called "form" which refers to the parent form

If you've attached an identifier to your form, use this:

$('#formId').submit();               //<form id="formId" ...
$('form[name="formName"]').submit(); //<form name="formName" ...
