Here is my code:
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var ColorId = "1";
$( "#targetButton" ).click(function() {
$.ajax({
url: 'checkcolors.php',
type: 'post',
dataType: 'json',
success: function (data) {
var arr = data.msg.split(',');
arr.forEach(function(id){
$('#' + id.trim()).hide();
});
//$('#target').html(data.msg);
},
data: ColorId
});
});
});
</script>
<button type="button" id="targetButton">Send</button>
<div class="BlackAndWhite" id="24604682">24604682</div>
<div class="BlackAndWhite" id="24604682x">24604682x</div>
<div class="BlackAndWhite" id="24604679">24604679</div>
<div class="BlackAndWhite" id="24604621">24604621</div>
Here is how the result looks like from checkcolors.php:
24604603, 24604684, 24604640, 24604609, 24604682, 24604686, 24604681, 24604689, 24604602, 24604679, 24604680, 24604622, 24604685, 24604683, 24604621, 24604677, 24604688,
And here is the code from checkcolors.php:
<?PHP
$url = 'http://www.sportsdirect.com/dunlop-mens-canvas-low-top-trainers-246046?colcode=24604622';
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$DataVariants = $xpath->query('//span[#class="ImgButWrap"]/#data-variants')->item(0)->nodeValue;
$jsonStart = strpos($DataVariants, '[');
$jsonEnd = strrpos($DataVariants, ']');
$collections = json_decode(substr($DataVariants, $jsonStart, $jsonEnd - $jsonStart + 1));
foreach ($collections as $item) {
$ColVarId = $item->ColVarId;
$SizeNames = [];
foreach ($item->SizeVariants as $size) {
$SizeNames[] = $size->SizeName;
}
if (in_array("7", $SizeNames)) {
echo "$ColVarId, ";
}
}
?>
When i click the button i am watching the browser console for any warnings or errors but there are none. Somehow it is not working and i do not know why.
It is supposed to hide all div elements with the same ids given from the checkcolors.php response, but it is not working. Why ?
Can you please help me out?
Thanks in advance!
Try to change this line:
var arr = data.msg.split(',');
to this:
var arr = data.split(',');
In your php script "checkcolors.php", you must return a JSON file.
$res = array();
foreach ($collections as $item) {
$ColVarId = $item->ColVarId;
$SizeNames = [];
foreach ($item->SizeVariants as $size) {
$SizeNames[] = $size->SizeName;
}
if (in_array("7", $SizeNames)) {
$res[] = $ColVarId;
}
}
echo json_encode($res);
Then in your javascript, you replace arr by data.
data.forEach(function(id){
$('#' + id.trim()).hide();
});

I have a page with ajax pagination on it, I am currently able to check if the session exists and process accordingly. However, I cannot seem to remove the menu or reload the page properly if the session has expired. Only the menu remains and the login page shows in the small area where the table was.
Controller code
public function index()
{
$conditions = array();
$data = array();
$totalRec = count($this->DocumentModel->admin_get_and_search($conditions));
$config['target'] = '#list';
$config['base_url'] = site_url('/AdminDocuments/Search');
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->get_per_page();
$this->ajax_pagination->initialize($config);
$data['links'] = $this->ajax_pagination->create_links();
$data['datatable'] = $this->DocumentModel->admin_get_and_search(array('limit'=>$this->get_per_page()));
$data['user'] = $this->AccountModel->get_person($this->get_person_id());
$data['current_page'] = $this->ajax_pagination->getCurrPage();
$this->load->view('layout/admins/common/header');

$this->index();
}else{
$conditions = array();
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$keywords = $this->input->post('keywords');

$data['current_page'] = $this->ajax_pagination->getCurrPage();
$this->load->view('admins/documents/ajax_pagination', $data, false);
}
}
}
My JS Code that is placed in the view
<script>
function searchFilter(page_num) {
page_num = page_num?page_num:0;
var keywords = $('#search').val();
$.ajax({
type: 'POST',
url: 'url/AdminDocuments/Search/'+page_num,
data:'page='+page_num+'&keywords='+keywords,
beforeSend: function () {
$('.loading').show();
},
success: function (html) {
$('#list').html(html);
$('.loading').fadeOut("slow");
}
});
}
function changeStatus(input){
var id = input;
$.ajax({
type:'POST',
url:'url/AdminDocuments/ChangeStatus/',
data:'id='+id,
beforeSend: function () {
$('.loading').show();
},
success:function(result){
console.log(result);
searchFilter(0);
$('.loading').fadeOut("slow");
}
});
}
function deleteDocument(input){
var id = input;
$.ajax({
type:'POST',
url:'url/AdminDocuments/Delete/',
data:'id='+id,
beforeSend: function () {
$('.loading').show();
},
success:function(result){
searchFilter(0);
$('.loading').fadeOut("slow");
}
});
}
</script>
i am assuming $('#list').html(html); code loads the html in the dom. instead of directly sending the html from php you can send a json containing the html as well the login status. like this.
$data = [
'login_status' => 1 // or 0,
'html' => $html // full html your are sending now
];
echo json_encode($data);
then in ajax success.
function searchFilter(page_num) {
page_num = page_num?page_num:0;
var keywords = $('#search').val();
$.ajax({
type: 'POST',
url: 'url/AdminDocuments/Search/'+page_num,
data:'page='+page_num+'&keywords='+keywords,
beforeSend: function () {
$('.loading').show();
},
success: function (response) {
var data = $.parseJSON(response);
if(data.login_status == 0)
{
window.location.href = 'redirect to login page';
}
if(data.login_status == 1)
{
$('#list').html(data.html);
}
$('.loading').fadeOut("slow");
}
});
}

I have to show the errors and success message on ajax call.
Right now I'm succeeded in valuating the data and putting it in the database.
But I want to show the success message at the end of the page by clicking the submit button.
And if there is validations error it must shows the errors in that fields at the end of the page
Any help would be appreciated.
Here inside your success method of ajax
success: function (data) {
$("#resultDiv").html(data)
}
Return some real data from your controller in both case success and failed. and based on your data inside success method show your message.
Like:
success: function (data) {
$("#resultDiv").html(data.success) //this requires string to convert your result in string if neccessary
//But you should return a JSON data as msg from your controller
}
You should put a result HTML element for example:
<div id='resultDiv'></div> <!-- to match with #resultDiv -->
Put response data in both condition if success=true and else success=false
In your controller
if(.....){
//what ever check you wanna do
..........
..........
$response['msg']='success';
header('Content-Type', 'application/json');
echo json_encode($response);
}
else{
$response['msg']='failed';
header('Content-Type', 'application/json');
echo json_encode($response);
}
In your ajax
success: function (data) {
$("#resultDiv").html(data.msg)
}
Try something like:
$response = array(
'errCode' = 0,
'errMsg' = 'msg'
);
return this kind of array by json_encode() from php to ajax() call and use it in ajax() success like:
var data = JSON.parse(response);
alert(data.errMsg);
You can also put a check on errCode like:
if(errCode == 0) { something }
if(errCode == 1) { something }
This code submits a form and an ID # to addBand.php. The php inserts the form data into a DB, and then echos an array that houses 2 arrays: 1 is an array of ids, the other is a string to update an HTML select element. I've only included the PHP that generates and echos the arrays.
i keep getting "Uncaught TypeError: Cannot read property 'selectRestults' of undefined" with the following code. what am I doing wrong?
javascript/jquery:
$(function() {
$("#addBandForm").submit(function(event) {
event.preventDefault();
var globalShowID = '&id=' + window.globalShowID;
$.ajax({

data: $('#addBandForm').serialize() + globalShowID,
success: function(msg) {
var actArray = msg['actIDArray'];
var bandArray = msg['bandSelectArray'];
var result = bandArray['selectResults'];
window.globalShowID='';
$("#band1").html(result)
},
error:function(errMsg) {
console.log(errMsg);
}
});
});
});
addBand.php
$bandSelectArray = array();
$actIDArray = array();
$bandResults = "";
if (isset($_POST['id']))

I can comment with only first item in while loop, When I tried to comment with another item it's always display alert box You know you need to write a comment right?. I think it can't get comment text on another item in my loop, What's wrong with my code?

$('.bt-cancel-com').click(function () {
$('.the-new-com').val('');
$('.new-com-cnt').fadeOut('fast', function () {
$('.new-com-bt').fadeIn('fast');

Can you please take a look at This Demo and let me know why I am getting empty array?
I have a jquery ajac request as:
$( "#appinfo" ).on( "submit", function( e ) {
var eTraget = $(".opacity").html().replace(/\D/g,'');
var senario = current;
if(qtype =="econo"){
var col = senario +"_"+eTraget;
var data='column='+col;
$.ajax({
type:"POST",
url:"assets/econo.php",
data:data,
dataType : 'json',
success:function(html) {
coords = html;
console.log(data);
st = map.set();
for (var i = 0; i < coords.length; i++) {
var circle = map.circle(coords[i][0], coords[i][1], 6);
st.push(circle);
}
e.preventDefault();
});
and econo.php as:
<?PHP
include 'conconfig.php';
$con = new mysqli(DB_HOST,DB_USER,DB_PASS,DB_NAME);
$collm = $_POST['column'];
$query = "SELECT x, y FROM econo WHERE".$collm."=1";
$results = $con->query($query);
$return = array();

}
}
$con->close();

As you can see I console.log(data); and the console display the result like column=ce_3000 but the $collm = $_POST['column']; is empty because whrn tried to dump it I just got an empty []. Can you please let me know why this is happening?
