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?
The NUMBER ONE error is having ANYTHING with the reserved word submit as ID or NAME in your form.
If you plan to call .submit() on the form AND the form has submit as id or name on any form element, then you need to rename that form element, since the form’s submit method/handler is shadowed by the name/id attribute.
Several other things:
As mentioned, you need to submit the form using a simpler event than the jQuery one
BUT you also need to cancel the clicks on the links
Why, by the way, do you have two buttons? Since you use jQuery to submit the form, you will never know which of the two buttons were clicked unless you set a hidden field on click.
<form action="deletprofil.php" id="form_id" method="post">
<div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
<button type="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" 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>
$(function(){
$("#NOlink, #OKlink").on("click", function(e) {
e.preventDefault(); // cancel default action
$("#popupDialog").popup('close');
if (this.id=="OKlink") {
document.getElementById("form_id").submit(); // or $("#form_id")[0].submit();
}
});
$('#form_id').on('submit', function(e){
e.preventDefault();
$("#popupDialog").popup('open');
});
});
Judging from your comments, I think you really want to do this:
<form action="deletprofil.php" id="form_id" method="post">
<input type="hidden" id="whichdelete" name="whichdelete" value="" />
<div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
<button type="button" value="1" class="delete ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Anlegen</button>
<button type="button" value="2" class="delete ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Bnlegen</button>
</div>
</form>
$(function(){
$("#NOlink, #OKlink").on("click", function(e) {
e.preventDefault(); // cancel default action
$("#popupDialog").popup('close');
if (this.id=="OKlink") {
// trigger the submit event, not the event handler
document.getElementById("form_id").submit(); // or $("#form_id")[0].submit();
}
});
$(".delete").on("click", function(e) {
$("#whichdelete").val(this.value);
});
$('#form_id').on('submit', function(e){
e.preventDefault();
$("#popupDialog").popup('open');
});
});
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
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().
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'));
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.
