Clearing a form and closing the div after successful post - javascript

I have a script that sends my form via php-ajax. It does return success but what I need it to do when it has been successful is clear all the form data and close the div and load another one. I have tried many different ways to clear form and close div but they just seem to stop it working totally. The id of the div to close is '5box' The working script that i need to add these to is :
$(document).ready(function() {
$('#btn-finish').on('click', function() {
// Add text 'loading...' right after clicking on the submit button.
$('.output_message').text('Processing...');
var form = $(this);
$.ajax({
url: form.attr('action'),
method: form.attr('method'),
data: form.serialize(),
success: function(result){
if (result == 'success'){
$('.output_message').text('Message Sent!');
} else {
$('.output_message').text('Error Sending email!');
}
}
});
// Prevent default submission of the form after clicking on the submit button.
return false;
});
});
Any ideas would be appreciated

To clear the form you can call the reset() method of the underlying Element. I'm not sure what you mean by 'close the div', but you can call hide() to make it disappear. Try this:
success: function(result) {
if (result == 'success') {
$('.output_message').text('Message Sent!');
form[0].reset();
$('#5box').hide();
} else {
$('.output_message').text('Error Sending email!');
}
}
Also note that it would be much better practice to return JSON from the AJAX call. You can then have a boolean flag to show the state of the request.
Update
<button name ='send' value="Send" type='submit' class='btn btn-primary'>Finish</button>
Given that is the code of your button there is another issue - you're not preventing the form from being submit, hence the AJAX request is cancelled. To do this, hook to the submit event of the form instead of the click of the button. From there you can call e.preventDefault() to stop form submission. Try this:
<script>
$(function() {
$('form').on('submit', function(e) {
e.preventDefault();
$('.output_message').text('Processing...');
var form = $(this);
$.ajax({
url: form.attr('action'),
method: form.attr('method'),
data: form.serialize(),
success: function(result) {
if (result == 'success') {
$('.output_message').text('Message Sent!');
form[0].reset();
$('#5box').hide();
} else {
$('.output_message').text('Error Sending email!');
}
}
});
});
});
</script>
Note I used a generic 'form' selector above. You can change that to a class or id selector on the form as required.

For clearing form fields
$("input[type=text], textarea").val("");
cheers

you can also use Triggers as well
$('#form_id').trigger("reset");

Ajax after ajax request, submit form normal way

I have ajax request:
<script>
$("#abc_form_submit").click(function(e) {
e.preventDefault();
//........
$.ajax({
type: "POST",
url: url,
dataType: 'json',
data: $("#abc_form").serialize(), // serializes the form's elements.
success: function(data)
{
if(data.success == 'false') {
// show errors
} else {
// SUBMIT NORMAL WAY. $("#abc_from").submit() doesnt work.
}
}
});
return false; // avoid to execute the actual submit of the form.
});
</script>
And php
.....
return $this->paypalController(params, etc...) // which should redirect to other page
.....
How should i make that ajax request if success, submit form normal way, because now if I redirect (at PHP) its only return response, but i need that this ajax request would handle php code as normal form submit (if success)
Dont suggest "window.location" please.
I would add a class to the form to test if your ajax has already occured. if it has just use the normal click funciton.
Something like:
$('form .submit').click(function(e) {
if (!$('form').hasClass('validated'))
{
e.preventDefault();
//Your code here
$.post(url, values, function(data) {
if (success)
{
$('form').addClass('validated');
$('form .submit').click();
}
});
}
}
Why don't you use a result variable that you update after a succesful AJAX request?
<script>
$("#abc_form_submit").click(function(e) {
e.preventDefault();
// avoid to execute the actual submit of the form if not succeded
var result = false;
//........
$.ajax({
type: "POST",
url: url,
dataType: 'json',
async: false,
data: $("#abc_form").serialize(), // serializes the form's elements.
success: function(data)
{
if(data.success == 'false') {
// show errors
} else {
// SUBMIT NORMAL WAY. $("#abc_from").submit() doesnt work.
result = true;
}
}
});
return result;
});
</script>
I've had this issue before where I needed the form to submit to two places, one for tracking and another to the actual form action.
It only worked by submitting it programatically when you put the form.submit() behind a setTimeout. 500ms seems to have done the trick for me. I'm not sure why browsers have trouble submitting the form programatically when they are attempting to submit them traditionally, but this seems to sort it out.
setTimeout(function(){ $("#abc_from").submit(); }, 500);
One thing to keep in mind though once it submits, that's it for the page, it's gone. If you still want whatever processes are running on the page to run, you will need to set the target of the form to _blank so that it will submit in a new tab.

Troubles Submitting Form programmatically

I have a simple page that takes a form and makes a jsonp ajax request and formats the response and displays it on the page, this is all fine, but I wanted to add it so that if the form was populated (via php $_GET variables) then the form would auto-submit on page load but what happens instead is that the page constantly refreshes despite the submit function returning false.
Submit Button (just to show it doesn't have an id like submit or anything)
<button type="submit" id="check" class="btn btn-success">Check</button>
jQuery
$(document).ready(function() {
$('#my_form').on('submit', function() {
var valid = 1;
$('#my_form .required').each(function() {
if ($(this).val() == '') {
$(this).parents('.form-group').addClass('has-error');
valid = 0;
} else {
$(this).parents('.form-group').removeClass('has-error');
}
});
if (valid === 1) {
$.ajax({
url: '/some_url',
data: $('#my_form').serialize(),
type: 'GET',
cache: false,
dataType: 'jsonp',
success: function(data) {
var html = 'do something with data';
$('#results').html(html);
},
error: function() {
$('#results').html('An error occurred, please try again');
}
});
} else {
$('#results').html('Please fill in all required fields');
}
return false;
});
});
The part I added just after the $(document).ready(function(){ and before the submit was:
if ($('#input_1').val() != '' || $('#input_2').val() != '') {
// $('#check').trigger('click');
$('#my_form').submit();
}
Both those lines have the same effect but I am doing the same in another project and it works fine, as far as I can see, the only difference is the jQuery version, I'm using 1.11 for this page.
Update
Apologies, I seem to have answered my own question, I thought that since the programmatic submit was the first thing in $(document).ready(function(){ then maybe it was the case that the actual submit function wasn't being reached before the event was triggered so I simply moved that block after the submitfunction and it now works fine.
url: ''
it seems like you are sending your ajax request to nothing.
just an additional: if you want to submit your form through jquery without using AJAX, try
$("#myForm").submit();
it will send your form to the action attribute of the form, then redirect the page there.

Post a huge html form by jQuery

I am trying to send a html form consisting of more than 100 sub fieldsets of 10 elements which it totally a huge form of more than 1000 elements.
I use jQuery to send this form. The problem is that it doesn't send all of the elements (it sends 84 sub fields out of 100).
I've been searching a lot but I have not found a reason or solution. Is it a limitation of jQuery or HTML or am I doing something wrong?
Here is the jQuery code:
$(document).on("submit", "#video_table", function() {
var action = $(this).attr('action');
var image_load = "<img src='/img/loading.gif' />";
$("#videoupdate-div").html(image_load);
// $.post(action, $(this).serialize(), function(data) {
// $("#videoupdate-div").html(data);
// });
$.ajax({
//dataType: "json",
url : action,
type : "POST",
data : $(this).serialize() ,
success : function(result) {
$("#videoupdate-div").html(result);
},
error : function(result) {
$("#videoupdate-div").html("Error! Something must be wrong.");
}
});
return false;
});
The form's own submission likely interferes with the submit event
Change
$(document).on("submit", "#video_table", function() {
to
$(document).on("submit", "#video_table", function(e) {
e.preventDefault(); // cancel the form's own submit
PS If the form is not dynamically inserted into the DOM, then this is enough
$("#video_table").on("submit", function(e) {
e.preventDefault();

validating form before it submit

WHAT IM DOING
I'm using jquery to validate form before it is send to server.
I'm validating every input, and if any of them return false i call event.preventDefault() and show the errors.(if it returns true I do nothing...)
THE PROBLEM
It was working fine, the script always run before the form send itself, but now I'm validating email, using ajax - checking if email isnt already in db or if the domain exists... but when the ajax starts, the the form wont wait until its finished and sends itself before the ajax finish and the input validates.
SOME SOLUTIONS MAYBE
I could call event.preventDefault() and after the validation is completed and it returns true I could try to undo the preventDefault perhabs by unbind and then submit through jquery submit the form again.
Or perhabs I could do onsubmit="checkInputs();" and it should wait until it returns true or false...
Solution - Adapted from the accepted answer by user Mirage
function validate(){
$.ajax({
url: 'http://google.nl',
async: false,
type: "POST",
data: {test:'request'},
success: function(data){
console.log(data);
}
});
return data; // important
}
try to add
async: false
example:
$.ajax({
url: 'http://google.nl',
async: false,
type: "POST",
data: {test:'request'},
success: function(data){
console.log(data);
}
});
you want:
onsubmit="checkInputs(); return false;"
Then you would grab the form e.g:
var frm = document.getElementById("myfrm");
frm.submit();
You would place the above in the else condition of your validation logic. Hope this helps.
Your script flow should be something like this:
Bind onsubmit handler
Send vars to server with ajax
Check results
When validates: remove handler and post form
When false: show error messages and start over again.
And in code:
var handleValidationResponse = function(data) {
if(data.errors != 0) {
alert('Sorry my dear user, but you made a mistake');
return false;
}
// aight, so it's all fine
$('#myForm').off('submit').trigger('submit'); // unbind custom submit handler and post the form
};
$('#myForm').on('submit', function(e) {
e.preventDefault();
var $this = $(this);
var serializedFormData = $this.serializeArray();
$.post($this.attr('action'), serializedFormData, function(data) {
handleValidationResponse(data);
});
});
That should be it!

jQuery override event.preventDefault()

I have a form that, when submitted, goes through the usual e.preventDefault() and sends an ajax request instead. However, if this ajax request returns a certain condition, I want the form to be submitted normally. How do I achieve this?
// Submit handler
$(".reserveer_form").submit(function(event){
event.preventDefault();
$.ajax({
url: $(this).attr("action"),
data: $(this).serialize(),
success: function(data) {
if($(".messagered",data).length > 0){
var errors = $(".messagered",data);
$(".gegevens").before(errors);
} else {
// SUBMIT THE FORM!
}
}
});
})
Invoke the native submit method on the form, so that it doesn't trigger the jQuery handler.
$.ajax({
context: this, // <-- set the context.
url: $(this).attr("action"),
data: $(this).serialize(),
success: function (data) {
if ($(".messagered", data).length > 0) {
var errors = $(".messagered", data);
$(".gegevens").before(errors);
} else {
this.submit(); // <-- submit the form
}
}
});
Since your comment says you change a form variable, you could start your submit handler by checking that same form variable. If it is changed, just return true. If not, continue with the current handler.
You can use the submit() method or forms:
$(".reserveer_form").submit(function(event){
event.preventDefault();
var form = this,
$form = $(form);
$.ajax({
url: $form.attr("action"),
data: $form.serialize(),
success: function(data) {
var errors = $(".messagered", data);
if (errors.length > 0){
$(".gegevens").before(errors);
} else {
form.submit();
}
}
});
})
However, this seems to be a strange ajax request. First, you send the form (serialized, via ajax) to the server, and when the response contains no errors you send it again? The server would process it twice (and act twice, depending on your form). Also, the user does not get a message that his input is already processed - he clicks "submit", and it always takes a time until it is visibly submitted (where he even could change some input).
