jQuery - Change action and form ID and use this - javascript

Apparently in the DOM have changed the values, even changed the ID of the form with the idea that the script no longer has effect but when you click Publish, nothing happens. Searching I tried to use "prop" instead of "attr" but it still does not work. I think it's because of the "e.preventDefault ()". But I do not know how to disable it. This is my code.
As you can see once the request is sent, the input and the "send" button are deactivated and when the values are received, they change the id of the form, the id and name of the button and it is renamed "Publish".
<script>
jQuery(function($){
var pluginUrl = '<?php echo plugin_dir_url( __FILE__ ); ?>' ;
$('[id^="form-search"]').on('submit', function(e) {
e.preventDefault();
$.ajax({
type : 'POST',
url : 'http://localhost/ladoserver/getapi.php',
data : $(this).serialize(),
cache: false,
beforeSend: function(){
$('input#keyword').prop('disabled', true);
$('button#search').prop('disabled', true);
$('#resuls').html('<img src="'+pluginUrl+'../../assets/img/loading.gif" />');
}
}).done(function(data) {
$('#results').html(data);
$('input#keyword').prop('value', 'PUBLISH DATA');
$('button#search').prop({disabled: false, id:'publish', name:'publish'}).html('Publish');
$('span#help').hide();
$('[id^="form-search"]').prop('action','publish.php');
$('[id^="form-search"]').prop('id', 'form-publish');
var countResults = $('input#total_data').val();
for (var i = 1; i <= countResults; i++) {
$('#lista>select').clone().prop({ id: "cat_"+i, name: "cat_"+i}).appendTo('.category_'+i);
}
$('#lista').remove();
});
});
});
</script>
Here my html
<form action="" method="post" class="form-search" id="form-search">
<fieldset>
<!-- Form Name -->
<legend>Name</legend>
<div class="form-group">
<input id="keyword" name="keyword" required="" type="text">
<button id="search" name="search" class="btn btn-success boton">Search</button>
<span class="help-block" id="help">Help</span>
<div id="lista" style="display:none">Test</div>
</div>
</fieldset>
<div id="result"></div>
</form>
Here a fiddle showing that happened (check DOM).

Cannot POST / error when clicking Submit button

I am developing a login page for our mobile app using Phone gap. But whenever I clicked the Submit button, an error 'Cannot POST /' appears. Why is that so? Please see my code below.
index.html

login.php
<?php
include "db.php";
if(isset($_POST['login'])){
$email=mysql_real_escape_string(htmlspecialchars(trim($_POST['email'])));
$password=mysql_real_escape_string(htmlspecialchars(trim($_POST['password'])));
$login=mysql_num_rows(mysql_query("select * from `user` where `email`='$email' and `password`='$password'"));
if($login!=0){
echo "success";
}else{
echo "failed";
}
}
?>
I didn't know where did I gone wrong with this. Please help me.
First of all it would be better to use on('submit', handler) instead on click. (see Whats the difference between onclick and onsubmit?)
When you clicks "Login", default form send action happens after your javascript code finishes. It means that form POST happens to 'action' of your form that is not set in your form and is '/' by default.
You need to preventDefault action, somethink like this
$('#login_form').on('submit', function(e) {
e.preventDefault();
//Your code
});

Submit multiple forms same jquery script

I have multiple forms and I want all of them to be processed by a single jquery script, of course I have php functions that work correctly, I tried them separately.
This is my script:
function proceso_form(type_form, id_div_error){
var url = "my_url.php?form="+type_form; //functions
var response = document.getElementById(id_div_error);
response.innerHTML="<img src='img/loader.gif' style='margin-right: 5px;'/>Loading ..."; //
response.style.display='block';
$.ajax({
type: "POST",
url: url,
data: $(this).serialize(), //ID form
success: function(data)
{
if (data==1){
window.location.reload();
}else{
response.innerHTML=data; // show PHP response.
}
}
});
return false;
};
My form looks like this
<form id="contacto" name="contacto" method="post" onsubmit="proceso_form('contacto', 'cargando')">
<input type="text" name="name"class="form-control">
<input type="text" name="phone" class="form-control">
<input type="email" name="email" class="form-control">
<textarea style="height:100px;margin-bottom:0px" name="messaje" class="form-control"></textarea>
<input style="margin-top:5px" type="submit" class="btn btn-block" value="SEND">
</form>
I think my problem is that I can't put my script in the onsubmit, but honestly I have no idea.
Your html must look like
<form id="contacto" name="contacto" method="post" onsubmit="return proceso_form(this, 'cargando')">
...
</form>
And inside the function:
function proceso_form(form, id_div_error){
var $form = $(form);
var url = "my_url.php?form="+$form.attr('id'); //functions
var response = document.getElementById(id_div_error);
response.innerHTML="<img src='img/loader.gif' style='margin-right: 5px;'/>Loading ..."; //
response.style.display='block';
$.ajax({
type: "POST",
url: url,
data: $form.serialize(), //ID form
success: function(data)
{
if (data==1){
window.location.reload();
}else{
response.innerHTML=data; // show PHP response.
}
}
});
return false;
};
By passing this to the function you passing the whole form reference.
Hope it will help.
First, it should be:
<form id="contacto" name="contacto" method="post" onsubmit="return proceso_form('contacto', 'cargando')">
The return keyword there is important.
Next, data: $(this).serialize(), //ID form should be:
data: $('#'+type_form).serialize(), //ID form
So, your script should look like this:
<script type="text/javascript" src="/path/to/jquery.min.js"></script>
<form id="contacto" name="contacto" method="post" onsubmit="return proceso_form('contacto', 'cargando')">
<input type="text" name="name" class="form-control">
<input type="text" name="phone" class="form-control">
<input type="email" name="email" class="form-control">
<textarea style="height:100px;margin-bottom:0px" name="messaje" class="form-control"></textarea>
<input style="margin-top:5px" type="submit" class="btn btn-block" value="SEND">
</form>
<div id="cargando"></div>
<script>
function proceso_form(type_form, id_div_error){
var url = "my_url.php?form="+type_form; //functions
var response = document.getElementById(id_div_error);
response.innerHTML="<img src='img/loader.gif' style='margin-right: 5px;'/>Loading ..."; //
response.style.display='block';
$.ajax({
type: "POST",
url: url,
data: $('#'+type_form).serialize(), //ID form
success: function(data)
{
if (data==1){
window.location.reload();
}else{
response.innerHTML=data; // show PHP response.
}
}
});
return false;
};
</script>

Ajax to send form to server, fails at serialize?

It seems like i cant get to serialize my form. I do get the first alert with lol, but not the second alert with pdata. Does anyone see whats wrong? Im trying to use ajax to send the data in the form. Down below is the script and the html code.
<html>
<head>
<script>
function dologin(event) {
event.preventDefault();
alert("lol");
var pdata = $('#form').serialize();
alert(pdata);
$.ajax({
type: 'POST',
data: pdata,
url: 'LINK',
success: function(data) {
//console.log(data);
alert("YAY");
},
error: function() {
//console.log(data);
alert("NAY");
}
});
};
</script>
</head>
<body>
<h1>Logg inn</h1>
<form id="form" onsubmit="dologin()">
<div class="form-group">
<label for="email">Epost</label>
<input type="email" class="form-control" name="login" value="" placeholder="Epost">
</div>
<div class="form-group">
<label for="password">Passord</label>
<input type="password" class="form-control" name="password" value="" placeholder="Passord">
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="remember_me">
Husk meg
</label>
</div>
<button type="submit" class="btn btn-default">Logg inn</button>
</form>
<div class="login-help">
<p>Glemt passordet? Trykk her for å endre det.</p>
</div>
</body>
</html>
The problem with your code is, you are accessing event argument wheres there is no parameter passed to the function, so its triggering an error and submitting the form as normal form submission.
If you like to keep your implementation u can modify your code like bellow:
function dologin() {
alert("lol");
var pdata = $('#form').serialize();
alert(pdata);
$.ajax({
type: 'POST',
data: pdata,
url: 'LINK',
success: function(data) {
//console.log(data);
alert("YAY");
},
error: function() {
//console.log(data);
alert("NAY");
}
});
return false;
};
and modify this line
<form id="form" onsubmit="dologin()">
to
<form id="form" onsubmit="return dologin()">
or can use the following way
$(document).ready(function() {
$('#form').submit(function(e){
e.preventDefault();
$.ajax({
type: 'POST',
data: $(this).serialize(),
url: 'LINK',
success: function(data) {
//console.log(data);
alert("YAY");
},
error: function() {
//console.log(data);
alert("NAY");
}
});
});
});
And form tag should be then:
<form id="form">

Form serialize issue

Here is my form's markup
<form name="contactForm" id="contactForm" role="form">
<div style="width: 190px">
<div class="form-group">
<input type="text" placeholder="fullname" name="fullname" id="formFullname" class="form-control">
</div>
<div class="form-group">
<input type="email" placeholder="email" name="email" id="fromEmail" class="form-control">
</div>
<div class="form-group">
<input type="text" placeholder="company" name="company" id="fromCompany" class="form-control">
</div>
</div>
<div class="clear"></div>
<div class="form-group">
<textarea placeholder="message" name="message" id="formMessage" rows="3" class="form-control"></textarea>
</div>
<button class="btn btn-success" type="submit" name="submit" id="formSubmit">send</button>
</form>
Using jquery 1.10.2
And here is JS
var form = $('#contactForm');
form.submit(function () {
console.log("form ", $(this).serialize());
$.ajax({
type: "POST",
url: url + "ajax/sendmail",
data: $(this).serialize(),
success: function (response) {
console.log(response);
}
});
return false;
});
I know that function fires, tested with alert. But console.log doesnt return anything, and during ajax call I don't see anything in POST (Watching with firebug's XHR).
BTW: role="form" is because i'm using Twitter Bootstrap framework
What am I doing wrong?
UPDATE
data: $(form).serialize() didn't help also
If you try this :
form.submit(function () {
console.log("form ", $(this).serialize());
return false;
});
it works just fine. So I think the problem
form.on('submit',function () {
event.preventDefault();
console.log("form ", $(this).serialize());
$.ajax({
type: "POST",
url: url + "ajax/sendmail",
data: $("form").serialize(),
success: function (response) {
console.log(response);
}
});
return false;
});
Because $(this) in your code doesn't refer to the form but instead refers to jQuery on which the ajax method is called
Try the following code, but first modify your form HTML so that is has an "action" attribute. The nice thing about this code is that it can be used on any form which has a submit button and an action attribute. (i.e. it is not coupled to any specific IDs)
$(function() {
$('input[type="submit"]').click(function(event) {
event.preventDefault();
var form = $(this).closest('form');
var url = form.attr('action');
var data = form.serialize();
$.post(url, data)
.done(function() {
alert('Yay! your form was submitted');
})
.fail(function() {
alert('Uh oh, something went wrong. Please try again');
});
});
Cheers.

Jquery form Ajax Submit

I want to submit a form using ajax in the background. I tried:
<div class="form-horizontal" id="form">
<label for="name" class="control-label">Username</label>
<div class="controls">
<span id="name_input"><input type="text" name="name" id="medium" class='input-medium input-square'></span>
<span class="help-inline" id = "ajax_load"></span>
</div>
<div class="form-actions">
<button class="btn btn-red5" onclick="resolve()">Login</button>
<input type="reset" class='btn btn-danger' value="Reset">
</div>
</div>
And the Javascript:
<script type="text/javascript">
var resolve = function () {
jAlert('test', 'test');
$('#ajax_load').html('<img src="templates/img/ajax-loader.gif" alt="">');
$.ajax( {
url : 'plugin.php?plugin=test',
type : 'post',
data: $("#form").serialize(),
success : function( resp ) {
if(resp.ajax_success == false) {
} else {
jAlert('test', 'test');
}
}
});
};
</script>
I get an alert, but there is no form submit. I checked that with Live http headers.
Why does it not submit the form?
If it doesn't submit the form, because, the #form is not a form.
Change:
<div class="form-horizontal" id="form">
To:
<form class="form-horizontal" id="form">
You need to replace the resp.ajax_success with resp. Let us also know the response of the plugin.php?plugin=test URL.
If you don't want the <form> to get submitted on clicking on the Submit button, add a return false; at the end of the resolve function this way:
var resolve = function () {
jAlert('test', 'test');
$('#ajax_load').html('<img src="templates/img/ajax-loader.gif" alt="">');
$.ajax( {
url: 'plugin.php?plugin=test',
type: 'post',
data: $("#form").serialize(),
success: function( resp ) {
if(resp.ajax_success == false) {
} else {
jAlert('test', 'test');
}
}
});
return false;
};
its because you haven't used the form you are serializing the data from div
<div class="form-horizontal" id="form">
not form the form
should be
<form class="form-horizontal" id="form">
