I am trying to set the content of an empty div after an AJAX call with the data message. I also wired the function to my CHtml::submitButton, which should call the function when clicked, but nothing is happening. Any suggestions?
<div id="myResult">
</div>
JavaScript:
function successMessage(){
$.ajax({
type: "GET",
data: "<div> Replace div with this contentf</div>",
success: function(data){
$('myResult').html(data);
}
})
}
PHP:
echo CHtml::beginForm(array('myForm'), 'get', array('form'));
echo '<div class="row form">';
echo '<div class="row buttons">';
echo CHtml::submitButton('Download Content', array('htmlOptions' => 'successMessage()'));
echo '</div>';
echo '</div>';
Your problem relies in the following line:
$('myResult').html(data);
Here, you are trying to do a jquery selection to an element, which you are not using in your html (this is only possible via pollyfils). So you have to select the element by its ID:
$('#myResult').html(data);
And another thing i've seen, what is the url where you are doing the request?
<script>
function successMessage(){
$.ajax({
type: "GET",
url: "/please/add/an/url/",
data: "<div> Replace div with this contentf</div>",
success: function(data){
$('myResult').html(data);
}
})
}
</script>
first of all, when you are using onclick function like this :
<input type="submit" onclick="successMessage()">
you should use this instead:
<input type="submit" onclick="successMessage();result false;">
but when you are already using jquery, then better approach is:
$( document ).ready(function() {
successMessage(){
// your ajax goes here
}
$('#myResult').click(function(e){
e.preventDefault();
successMessage();
});
});
Then you need to repair your successMessage function. You see, the data you are setting there are not the data, that are coming out as an output. If you need ajax then you probably want to get the result from some php script on some other url. Then you should do it like this :
function successMessage(){
$.ajax({
type: "GET",
url : 'index2.php',
dataType: "json",
data: { mydata: '<div> Replace div with this content</div>'},
success: function(data){
$('#myResult').html(data);
}
})
}
Then you need a php file named index2.php which can look like this :
<?php
echo json_encode($_GET['variable']);
?>
And i dont know if this your line :
echo CHtml::submitButton('Download Content', array('htmlOptions' => 'successMessage()'));
also put the </form> tag after the form to close it.
This should work for you. I tried it and it works fine.
Try this:
$.ajax({
url: "test.html",
type: "GET",
data: "<div> Replace div with this contentf</div>",
success: function(data){
$('#myResult').html(data);
}
})
selector jQuery incorrect in response ajax. and define Url in ajax.

I have this link that is supposed to delete an entry and refresh a div via ajax. However, for some reason it isn't working at all and its just shifting the page up and adding a # to the url.
If I add an alert to output the id and user_id, it shows up and no # is added to the url.
This is the code
<script>
function removeExistingBranch(id,user_id){
$.ajax({
method: "POST",
url: "<?php echo site_url($this->data['controller'].'/RemoveUserBranch/'); ?>",
data:'id='+id+,
'&user_id'+user_id,
beforeSend: function () {
$('.loading').show();
},
success: function(data){
// $( "#existing_branch_container" ).load( "<?php echo site_url($this->data['controller']);?>/LoadUserBranches" );
$('.loading').fadeOut("slow");
},
});
return false;
}
</script>
Remove
Could someone take a look and see if I am missing something?
You have syntax error in the ajax call. Change it
data:'id='+id+,'&user_id'+user_id,
to
data:'id='+id+'&user_id'+user_id,
I am a ajax beginner, Here I am trying to show a text box value in same page using Ajax.
My Controller code:
<?php
class Merchant extends CI_Controller
{
public function ajaxtest()
{
$this->load->helper('url');
$this->load->view('ajaxtest');
$fullname = $this->input->post("fullname");
echo $fullname;
}
}
?>
Here is my view code:
<head>
<script src="<?php echo base_url();?>assets/js/jquery-latest.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#getinfo").click(function()
{
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>merchant/ajaxtest",
data: {textbox: $("#fullname").val()},
dataType: "text",
cache:false,
success:
function(data){
$('#mytext').html(data);
}
});
return false;
});
});
</script>
</head>
<body>
<form method="post">
<input type="text" id="fullname"/>
<input type="button" value="getinfo" id="getinfo"/>
<span id="mytext"></span>
</form>
</body>
When I click on the button getinfo, I want to show the text inside the text box as span text. But now it shows nothing..
Updated:
After experts' opinion, I edited some text(see my edit note), Now When i click on the button, it shows again a textbox and a button.. !!
Did you set the base_url variable with a link on the Javascript?
Because your post url contains this variable and you need set this to make it work. So initialize the variable with the base_url link.
See the corrected example below . Set your domain instead of the yourbaseurl.com
<script type="text/javascript">
$(document).ready(function(){
var base_url='http://yourbaseurl.com/index.php/';
$("#getinfo").click(function()
{
$.ajax({
type: "POST",
url: base_url + "merchant/ajaxtest",
data: {textbox: $("#fullname").val()},
dataType: "text",
cache:false,
success:
function(data){
$('#mytext').html(data);
}
});
return false;
});
});
</script>
Your base_url variable seems to be undefined in your JavaScript.
One simple approach to get the base URL is to echo it out in a hidden input, and then grab the value of that input in your JS code:
HTML
<input type='hidden' id="baseUrl" value="<?php echo base_url(); ?>" />
JS
var base_url = $('#baseUrl').val();
$.ajax({
type: "POST",
url: base_url + "/merchant/ajaxtest",
data: {textbox: $("#fullname").val()},
dataType: "text",
// ...
you are passing in textbox as parameter from your ajax to controller and trying to get POST data with name fullname. That wont work, since you passed in the name of parameter as textbox, access that in your post, as :
class Merchant extends CI_Controller
{
public function ajaxtest()
{
$this->load->helper('url');
//you dont need to load view so comment it
//$this->load->view('ajaxtest');
$fullname = $this->input->post("textbox"); //not fullname
echo $fullname;
}
}
js
<script type="text/javascript">
$(document).ready(function(){
var base_url='http://yourbaseurl.com/index.php/';
$("#getinfo").click(function() {
var fullname = $("#fullname").val();
alert("Fullname:" + fullname); //do you get this alert
$.ajax({
type: "POST",
url: base_url + "merchant/ajaxtest",
data: {textbox: fullname},
cache:false,
success:function(data){
alert("Response:" + data); //do you get this alert
$('#mytext').html(data);
}
});
return false;
});
});
</script>
Try using this:
<base href="<?=base_url();?>">
<script src="assets/js/jquery-latest.min.js"></script>
And this in ajaxtest:
$this->load->helper('url');
And also Comment out this:
// $this->load->view('ajaxtest');

I was having the same issues with Codeigniter and JQuery ajax/post response. I could not get this to work no matter what I tried.
In the end, it turned out to be php_error that was causing the problem. Once I removed it, everything worked fine with my post/response.
this is my html code:
<form id="form" action="javascript:void(0)">
<input type="submit" id="submit-reg" value="Register" class="submit button" onclick="showtemplate('anniversary')" style='font-family: georgia;font-size: 23px;font-weight: normal;color:white;margin-top:-3px;text-decoration: none;background-color: rgba(0, 0, 0, 0.53);'>
</form>
this is my javascript code:
function showtemplate(temp)
{
$.ajax({
type: "POST",
url: 'ajax.php',
data: "section="+temp ,
success: function(data)
{
alert(data);
}
});
}
this is my ajax.php file:
<?php
$ajax=$_POST['section'];
echo $ajax;
?>
The above html and javascript code is included in a file named slider.php. In my index file i have included this slider.php file and slider.php is inside slider folder. So basically index.php and slider.php are not inside the same folder.
Javascript code alerts the data properly. But in my php code (ajax.php file) the value of $_POST['section'] is empty. What is the problem with my code. I tried googling everything and tried a few codes but it still doesn't work. Please help me out
Try this instead:
$.ajax({
type: "POST",
url: 'ajax.php',
data: { 'section': temp},
success: function(data)
{
alert(data);
}
});
It is quite possible that your server does not understand the string you have constructed ( "section="+temp ). When using ajax I prefer sending objects since for an object to be valid it requires a certain format.
EDIT1:
Try this and let me know if it doesn't work either:
$.post('ajax.php', {'section': temp}, function(data}{
alert(data);
});
Add jquery plugin(jQuery library) ,then only ajax call works
for eg
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
check your input data , whether it contain '&,/' charators,then use encodeURIComponent()
for Ajax Call Eg:
var gym_name = encodeURIComponent($("#gym_name").val());
$.ajax({
type: "POST",
url: "abc.php",
data:string_array,
success: function(msg) {
console.log(msg);
}
});
In abc.php
<?php
$id = $_POST['gym_name'];
echo "The id is ".id;
?>
Give a try to the following (although I cannot work out why #Grimbode's answer is not working):
$("#submit-reg").on( "click", function() {
$.ajax({
type: "POST",
url: 'ajax.php',
data: {'section': 'anniversary'},
success: function(data)
{
alert(data);
}
});
});
Note: I don't know what your underlying code is doing. However, I would suggest not using HTML element properties to handle events for numerous reasons, but separate the JS/event handling appropriately (separate js file(s) (recommended) or inside <script> tags). Read more...
I have a form that when clicked the submit button makes a call via ajax. This ajax is inside a php file because I need to fill in some variables with data from the database. But I can not use the calls before / success. They just do not work, I've done tests trying to return some data, using alert, console.log and nothing happens. Interestingly, if the ajax is isolated within a file js they work. Some can help me please?
File:
<?php
$var = 'abc';
?>
<script type="text/javascript">
$(document).ready(function() {
$('#buy-button').click(function (e){
var abc = '<?php echo $var; ?>';
$.ajax({
type: 'POST',
data: $('#buy-form').serialize(),
url: './ajax/buy_form.php',
dataType: 'json',
before: function(data){
console.log('ok');
},
success: function(data){
},
});
});
});
</script>
HTML:
<form id="buy-form">
<div class="regular large gray">
<div class="content buy-form">
/* some code here */
<div class="item div-button">
<button id="buy-button" class="button anim" type="submit">Comprar</button>
</div>
</div>
</div>
</form>

EDIT

Problem solved! The error was in the before ajax. The correct term is beforeSend and not before. Thank you all for help.
You said it was a submit button and you do not cancel the default action so it will submit the form back. You need to stop that from happening.
$('#buy-button').click(function (e){
e.preventDefault();
/* rest of code */
Now to figure out why it is not calling success
$.ajax({
type: 'POST',
data: $('#buy-form').serialize(),
url: './ajax/buy_form.php',
dataType: 'json',
before: function(data){
console.log('ok');
},
success: function(data){
},
error : function() { console.log(arguments); } /* debug why */
});
});
My guess is what you are returning from the server is not valid JSON and it is throwing a parse error.
Try this
<script type="text/javascript">
$(document).ready(function() {
$('#buy-button').click(function (e){
e.preventDefault();
var abc = '<?php echo $var; ?>';
$.ajax({
type: 'POST',
data: $('#buy-form').serialize(),
url: './ajax/buy_form.php',
dataType: 'json',
beforeSend: function(data){
console.log('ok');
},
success:function(data){
}
});
});
});
And make sure that your php file return response
EDIT:
This is what i managed to build...but it still dont work..
$(document).ready(function(){
$("tr").click(function(){
txt=$("input[name=path]").val();
$.ajax({
type: "POST",
url: contract.php, // the same page where i have the table
data: txt, // the variable containing the dynamic id from the clicked row
success: success, // i have no idea what is this parameter for....
dataType: dataType // i have no idea what is this parameter for....
});
});
});
PHP:
$row=mysql_fetch_array($query){
echo '<tr id="'.$row['id'].'">';
echo '<td></td>';
echo '</tr>';
}
What i want,is when the user click on a row , the row id(which is dynamic), must be taken , and returned with ajax post , so i can use it in another query.I have to do this without reloading the page, thats why i try to do it with ajax.
If it's ok to use jQuery i would use something like this to build my table (beside the mysql_*):
<?php
$row=mysql_fetch_array($query){
echo '<tr class="listContractRow" data-path="'.$row['id'].'">';
echo '</tr>';
}
?>
Then catch the click event with a jQuery listener:
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script>
$(document).on('click','tr.listContractRow', function(e){
var path = $(this).data('path');
//Use the variable path here in your AJAX call
//Assuming you want a GET request, you can also use $.ajax or $.post here
$.get('YOUR_AJAX_URL_HERE?path='+path, function(){
//Do something after the ajax call
});
});
</script>
EDIT
In your PHP you can do something like:
<?php
if(isset($_GET['path']))
{
//Query here with the variable $_GET['path'];
//Echo the results you want
//Perform an exit here, since it's an AJAX call. You probably don't want to echo the code below (if there is)
exit();
}
?>
jquery ajax get example
$.ajax({
type: "POST",
url: "index.php",
data: "{param: "param"}",
success: function(msg) {
},
error: function(err) {
}
});
