Is it possible to submit form twice? - javascript

I have the situation like updating values to db when form is submitted.Issue here is, Total is calculated only after form is submitted. so i have to update the calculated total again in DB. I need to submit again manually to update it. To achieve this we can use jquery here to form submitted second time with out click it again. Is there quick way to do this ?
Kindly advice ?

You can use ajax to submit form twice, see following code:
function submit() {
var form = $('#your-form');
$.ajax({
type: 'POST',
url: form.attr('action'),
data: form.serialize(),
success: function(data) {
$.ajax({
type: 'POST',
url: form.attr('action'),
data: form.serialize(),
success: function(data) {
}
});
}
});
}

Cannot get $_POST('input') using jQuery .submit()

I was trying to upload a form using jQuery's submit() and success in redirect the page to uploadAll.php, but when I was trying to get the input array using $_POST['inputname'] I can not obtain the value.
I was trying to use serialize() but I get confused in where I should put my PHP page reference.
<form id="regForm" action="uploadAll.php" method="post" enctype="multipart/form-data">
//some inputs and a hidden input here
</form>
document.getElementById("regForm").submit(function() {
var inputValues = $(this).serialize();
$.ajax({
url: "uploadAll.php",
type: "POST",
data: inputValues
}).done(function(data) {
alert(data);
});
});
return false;
Can I just submit without using serialize()? It seems my serialize does not work. Any help is appreciated
trust me, your code is wrong..
try use this code instead:
$("#regForm").on('submit', function(e) {
e.preventDefault();
var inputValues = $(this).serialize();
$.ajax({
url: "uploadAll.php",
type: "POST",
data: inputValues
}).done(function(data) {
alert(data);
});
});

AJAX form submitting multiple values to MySQL even after using bind unbind, on off

Okay so this problem has been solved multiple times but mine is a bit more complicated. The following is my AJAX which takes as input Text fields and image and submits the fields and file path to the database.
$(function () {
$('form#data').off('submit').on('submit',function () {
var formData = new FormData($(this)[0]);
$.ajax({
type:'POST',
url: 'upload.php',
data: formData,
async:false,
cache:false,
contentType: false,
processData: false,
success: function (returndata) {$('#result').html(returndata);}
});
return false;
});
});
Now when I submitted a file it was uploaded normally. Then if I tried submitting a second file, it created multiple copies on the database. And it went on exponentially increasing as I went on uploading further.
So I looked up and saw that bind/ unbind and on/off were two solutions.
This worked for for the second file uploaded, but from the third file onwards the repetition continued.
Please let me know where i am going wrong.
Thanks.
Okay so I solved it. I removed the on off and did this. Now works fine!
$(function () {
$('form#data').submit(function (e){
e.preventDefault();
e.stopImmediatePropagation();
var formData = new FormData($(this)[0]);
$.ajax({
type:'POST',
url: 'upload.php',
data: formData,
async:false,
cache:false,
contentType: false,
processData: false,
success: function (returndata) {$('#result').html(returndata);}
});
return false;
});
});

Form submitting to wrong function when changing class dynamically

I'm sure there's a simple explanation for this but I haven't been able to find the right words to use when searching for answers.
When users fill out the form .InvoiceForm it submits via Ajax. After it's submitted remove the .InvoiceForm class and add .UpdateInvoice. When a user submits a .UpdateInvoice form it explains that they are about to make a change and they have to click to say "Yes I want this to be updated".
The issue is that unless I refresh the page so that the form is loaded with the .UpdateInvoice form, I don't get the confirmation which means it's still submitting as a .InvoiceForm form. Is there anything I can do to fix this?
Edit to show code:
Code that runs if there's no record
$('.InvoiceForm').submit(function(e) {
$.ajax({
url: $(this).attr('action'),
type: 'POST',
cache: false,
dataType: 'json',
context: this,
data: $(this).serialize(),
beforeSend: function() {
$(".validation-errors").hide().empty();
},
success: function(data) {
$(this).removeClass('InvoiceForm');
$(this).addClass('UpdateInvoice');
$(this).find('.btn').val('Update');
$(this).find('.id').val(data.invoice_id);
$(this).find('.btn').removeClass('btn-default');
$(this).find('.btn').addClass('btn-danger');
$(this).find('.AddRow').removeClass('hide');
$(this).find('.invoiceDetails').html(data.returnedData);
$(this).parent().next().find('.grade').focus();
}
});
return false;
};
Code that runs if there is a record being updated
$('.UpdateInvoice').submit(function(){
var r = confirm("Are you sure you want to make this update?");
if (r == true) {
$.ajax({
url: $(this).attr('action'),
type: 'POST',
cache: false,
dataType: 'json',
context: this,
data: $(this).serialize(),
beforeSend: function() {
$(".validation-errors").hide().empty();
},
success: function(data) {
alert('This row has been updated');
$(this).find('.total').html(data);
}
});
} else {
}
return false;
});
The function for .UpdateInvoice doesn't run unless I refresh the page.
Thanks for your help.
You bind a click event on '.UpdateInvoce' before it even being created, hence it'll not work. I think you need to use .live() in order to make it works. See document here: jQuery's live()
HTML:
<button id="click_me" class="new">Click Me</button>
<div class="result" />
Script:
$(function () {
$('.new').click(function (e) {
$('.result').text("Im new !");
$(this).removeClass("new");
$(this).addClass("update");
// Bind UpdateInvoice's click event on the fly
$('.update').live(bindUpdate());
});
function bindUpdate() {
$('.update').click(function (e) {
$('.result').text("Update me !");
});
}
});

AJAX success callback only carrying out first function

I've got a simple form submission that upon success I've got an alert and a call to clear the form. I do get the alert, the info gets successfully added to the database, but the second call--for the form to clear, is not being carried out. I'm sure it's something simple I'm doing wrong, but I can't figure it out.
$('#contact_submit').click(function(e){
if ($("#submit_form_contact").valid()) {
var post_data = {
"name" : $('#name').val(),
"email" : $('#email').val(),
"inquiry" : $('#inquiry_dropdown option:selected').text(),
"message" : $('#message').val()
};
$.ajax({
type: "POST",
url: "process-contact.php",
data: post_data,
success: function(data) {
alert("Thank you for contacting us.");
$('#submit_form_contact').reset();
}
});
e.preventDefault();
}
Also, the submit button is just a button, not a submit input. Is it necessary to preventDefault()? I'm new at this.
jQuery doesn't have a .reset() method.
Do this instead:
$('#submit_form_contact')[0].reset();
This grabs the first DOM element, and invokes the native .reset(). If there's any chance the form won't be found, then test for the element.
var f = $('#submit_form_contact')[0];
if (f)
f.reset();
And of course you don't really need jQuery to get an element by ID, especially if you're not going to use any jQuery methods.
var f = document.getElementbyId('submit_form_contact');
if (f)
f.reset();
Another alternative would be to set the submit button as the context: of the ajax call, then use its form property.
$.ajax({
context: this,
type: "POST",
url: "process-contact.php",
data: post_data,
success: function(data) {
alert("Thank you for contacting us.");
this.form.reset();
}
});
this line can be used too
$("#submit_form_contact").trigger('reset');

Jquery help repeated ajax call

When I submit my form, a repeated ajax call is made it never stop.
Here is my Jquery for the ajax call on form submit:
$('form#formgo').submit(function(e) {
e.preventDefault();
$('#comparecontent').empty().html(
'<p style="text-align:center;">' +
'<img src="../images/ajax.gif" /></p>');
var form = $(this).closest('form');
$.ajax({
type: form.attr('method'),
url: form.attr('action'),
data: form.serialize(),
success: function(msg){
$('#comparecontent').html(msg);
}
});
return false;
});
In your ajax call, try specifying a timeout for the request:
$.ajax({
type: form.attr('method'),
url: form.attr('action'),
data: form.serialize(),
timeout: 3000, // time in milliseconds
success:function(msg){
$('#comparecontent').html(msg);
}
});
see the .ajax() documentation for more info on available params http://api.jquery.com/jQuery.ajax/
It seems that something is triggering submit.
Try event.stopPropagation()
$('form#formgo').submit(function(e) {
e.preventDefault();
e.stopPropagation();
...
Also check if an onchange event is bound to elements with id comparecontent.
