[jquery] Form Submit jQuery does not work

I have that form

<form action="deletprofil.php" id="form_id" method="post">
            <div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
                <button type="submit" name="submit" value="1" class="ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Anlegen</button>
                <button type="submit" name="submit" value="2" class="ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Bnlegen</button>
            </div>
        </form> 

and that Popup from jQuery Mobile

<div class="ui-popup-container pop in ui-popup-active" id="popupDialog-popup" tabindex="0" style="max-width: 1570px; top: 2239.5px; left: 599px;">
    <div data-role="popup" id="popupDialog" data-overlay-theme="b" data-theme="b" data-dismissible="false" style="max-width:400px;" class="ui-popup ui-body-b ui-overlay-shadow ui-corner-all">
        <div data-role="header" data-theme="a" role="banner" class="ui-header ui-bar-a">
            <h1 class="ui-title" role="heading" aria-level="1">Delete Page?</h1>
        </div>
        <div role="main" class="ui-content">
            <h3 class="ui-title">Sicher dass Sie das Profil löschen wollen?</h3>
            <p>Es kann nicht mehr rückgängig gemacht werden.</p>
            <a href="#" id="NOlink" class="ui-btn ui-corner-all ui-shadow ui-btn-inline ui-btn-b">Abbrechen</a>
            <a href="#" id="OKlink" class="ui-btn ui-corner-all ui-shadow ui-btn-inline ui-btn-b">OK</a>
        </div>
    </div>
  </div>

with my jQuery Code

<script language="javascript" type="text/javascript">
$(function(){
    $('#form_id').bind('submit', function(evt){
        $form = this;
        evt.preventDefault();
        $("#popupDialog").popup('open');
        $("#NOlink").bind( "click", function() {
            $("#popupDialog").popup('close');
        });
        $("#OKlink").bind( "click", function() {              
            $("#popupDialog").popup('close');   
            $( "#form_id" ).submit();         
        });         
    });
});    
    </script>

The popup shows up but the form submit does not work. Does someone have any ideas?

if there is one error in the the submit function,the submit function will be execute. in other sentences prevent default(or return false) does not work when one error exist in submit function.

Some time you have to give all the form element into a same div.

example:-

If you are using ajax submit with modal.

So all the elements are in modal body.

Some time we put submit button in modal footer.

Don't forget to close your form with a </form>. That stopped submit() working for me.

Since every control element gets referenced with its name on the form element (see forms specs), controls with name "submit" will override the build-in submit function.

Which leads to the error mentioned in comments above:

Uncaught TypeError: Property 'submit' of object #<HTMLFormElement> is not a function

As in the accepted answer above the simplest solution would be to change the name of that control element.

However another solution could be to use dispatchEvent method on form element:

$("#form_id")[0].dispatchEvent(new Event('submit')); 

You can use jQuery like this:

$(function() {
    $("#form").submit(function(event) {
        // do some validation, for example:
        username = $("#username").val();
        if (username.length >= 8)
            return; // valid
        event.preventDefault(); // invalidates the form
    });
});

In your HTML:

<form id="form" method="post">
    <input type="text" name="username" required id="username">
    <button type="submit">Submit</button>
</form>

https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/submit_event https://api.jquery.com/submit/

According to http://api.jquery.com/submit/

The submit event is sent to an element when the user is attempting to submit a form. It can only be attached to elements. Forms can be submitted either by clicking an explicit <input type="submit">, <input type="image">, or <button type="submit">, or by pressing Enter when certain form elements have focus.

So basically, .submit is a binding function, to submit the form you can use simple Javascript:

document.formName.submit().

Alright, this doesn't apply to the OP's exact situation, but for anyone like myself who comes here facing a similar issue, figure I should throw this out there-- maybe save a headache or two.

If you're using an non-standard "button" to ensure the submit event isn't called:

<form>
  <input type="hidden" name="hide" value="1">
  <a href="#" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

Then, when you try to access this.form in the script, it's going to come up undefined. As I discovered, apparently anchor elements don't have same access to a parent form element the way your standard form elements do.

In such cases, (again, assuming you are intentionally avoiding the submit event for the time-being), you can use a button with type="button"

<form>
  <input type="hidden" name="hide" value="1">
  <button type="button" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

(Addendum 2020: All these years later, I think the more important lesson to take away from this is to check your input. If my function had bothered to check that the argument it received was actually a form element, the problem would have been much easier to catch.)

If you are doing form validation such as

type="submit" onsubmit="return validateForm(this)"

validateForm = function(form) {
if ($('input#company').val() === "" || $('input#company').val() === "Company")  {
        $('input#company').val("Company").css('color','red'); finalReturn = false; 
        $('input#company').on('mouseover',(function() { 
            $('input#company').val("").css('color','black'); 
            $('input#company').off('mouseover');
            finalReturn = true; 
        }));
    } 

    return finalReturn; 
}

Double check you are returning true. This seems simple but I had

var finalReturn = false;

When the form was correct it was not being corrected by validateForm and so not being submitted as finalReturn was still initialized to false instead of true. By the way, above code works nicely with address, city, state and so on.

Because when you call $( "#form_id" ).submit(); it triggers the external submit handler which prevents the default action, instead use

$( "#form_id" )[0].submit();       

or

$form.submit();//declare `$form as a local variable by using var $form = this;

When you call the dom element's submit method programatically, it won't trigger the submit handlers attached to the element
