Refer to the following code, this script doesn't post the "limit" variable to the next page
MY JS Code:
$(document).ready(function(){
$(window).scroll(function() {
if ($('body').height() <= ($(window).height() + $(window).scrollTop())) {
var dataString="2";
$.ajax({
type:"POST",
url: "load_data.php",
data: { 'limit': dataString },
success:function(data) {
$('#leftNews').load('load_data.php');
}
});
}
});
});
PHP CODE
<?php
if(isset($_POST['limit'])) {
echo $_POST['limit'];
}
else echo 'asd';
?>
Everytim i run this i get "asd" printed
That's because you're loading the PHP page, instead of loading the result.
$(document).ready(function() {
$(window).scroll(function() {
if ($('body').height() <= ($(window).height() + $(window).scrollTop())) {
var dataString = "2";
$.ajax({
type: "POST",
url: "load_data.php",
data: {'limit': dataString},
success: function(data) {
$('#leftNews').html(data);
}
});
}
});
});
You make two different ajax requests. The first one is a POST-request with limit-variable set. The more important one is the second one, it is a load-requests (which is a get-requests without any parameters). Of course, your last request which shall print out the result does not containt any parameters, thats why "asd" is printed - the limit is NOT set!
In order to get the wanted result, you should change it to:
success:function(data) {
$('#leftNews').html(data);
}

when i try get and echo the variable on php, sending by ajax, i receive always var_dump null
the alert is ok, he shows the current slide id number when <a>(role=button) prev or next is clicked: 1 on slide 1, 2 on 2, 3 on 3;
<script>
$("#myCarousel").on('slide.bs.carousel', function(e) {
var value1 = $(this).find('.carousel-item.active').attr('id');
alert(value1);
var value = {
idCarrosselAtivo: $(this).find('.carousel-item.active').attr('id')
}
$.ajax({
type: "POST",
url: "teste.php",
data: value,
success: function(data) {
console.log(data);
}
});
})
</script>
<?php
if(isset($_POST['idCarrosselAtivo'])&& $_POST['idCarrosselAtivo'] === 'c1') {
echo $idCarrossel;
} else {
var_dump($idCarrossel);
}
?>
Consider this example.
jQuery
$("#myCarousel").on('slide.bs.carousel', function(e) {
console.log("Sending ", $(this).find('.carousel-item.active').attr('id'));
$.ajax({
type: "POST",
url: "teste.php",
data: {
idCarrosselAtivo: $(this).find('.carousel-item.active').attr('id')
},
success: function(data) {
console.log(data);
}
});
});
PHP
<?php
if(isset($_POST['idCarrosselAtivo'])){
$idCarrossel = $_POST['idCarrosselAtivo'];
if($idCarrossel === 'c1') {
echo $idCarrossel;
} else {
var_dump($_POST['idCarrosselAtivo']);
}
}
?>
It's not clear why you are sending back the ID when you just sent it to the script. This will send the ID and get some PHP back.
Don't know what is wrong, I've tried everything. The code should take simple info from PHP file and for each should fade in delay and out. I was successful with getting all the data at once but it is not good.
<script type="text/javascript">
$('button').fadeOut('slow')
var progressBar = $('.progress-bar');
var percentVal = 0;
window.setInterval(function(){
percentVal += 10;
progressBar.css("width", percentVal+ '%').attr("aria-valuenow", percentVal+ '%').text(percentVal+ '%');
if (percentVal == 100)
{
percentVal = 0;
}
}, 500);
$(document).ready(function() {
$("button").click(function() {
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "submit.php",
data: 'html', //expect html to be returned
success: function(data){
for(var i=0;i<6;i++){
$('.input-group').html(data).fadeIn(500).delay(1000).fadeOut(500);
}
}
});
});
});
</script>
PHP CODE:
$array= ['apple','orange','grapes','avocado','banana'];
$indexedOnly = array();
foreach ($array as $row) {
$indexedOnly[] = array_values($row);
}
echo json_encode($indexedOnly);
I think you need to abandon the loops, they wont allow you to pause to wait for the animation to finish. You can try something like this where you handle each element in data then using the callback functions of .fadeIn and .fadeOut to call the next one
function disp_next() {
$('.input-group').text(data.shift()).hide();
$('.input-group').fadeIn()
.delay(1000)
.fadeOut(function(){
if(data.length !== 0) {
disp_next();
}
})
}
disp_next();
You also need to change your dataType to json as you are expecting json from the server. Here is your jquery updated
$(document).ready(function() {
$("button").click(function() {
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "submit.php",
datatype: 'json', //expect html to be returned
success: function(data){
data = Object.values(data);
function disp_next() {
$('.input-group').text(data.shift()).hide();
$('.input-group').fadeIn()
.delay(1000)
.fadeOut(function(){
if(data.length !== 0) {
disp_next();
}
})
}
disp_next();
}
});
});
});
Try something like this, but if you want the animation of each element to wait for the previous one to finish you need to change the approach.
$.each(data, function(i, value) {
$('.input-group').html(data).fadeIn(500).delay(1000).fadeOut(500);
});
I have a javascript coding that pulls a PHP file, and if it updates the database, it will echo Success: Age Updated! It works and all, But When I click it multiple times it will start to do this.. Sucsess: Age Changed! Sucsess: Age Changed! Sucsess: Age Changed! .. Here's the Javascript.
function UpdateAge(Age) {
var newage = $("#NewAge").val();
var dataString = 'newage=' + newage;
if (newage.length < 2) {
$('#Required').fadeIn(300);
$('#Mask').fadeIn(300);
} else {
$.ajax({
type: "POST",
url: "update_age.php",
data: dataString,
cache: false,
success: function (updateage) {
$("#UpdatedAge").append(updateage);
$("#UpdatedAge").show().fadeOut(1200);
}
});
}
}
How would I get it to just display Success: Age Updated! once, instead of it just multiplying everytime I click?
Here's the Button for the onClick
<input type="submit" value="Update" onClick="UpdateAge(<?php echo $age ?>)" />
Looks like you just need to empty your #UpdatedAge Element each time.
function UpdateAge(Age) {
var newage = $("#NewAge").val();
var dataString = 'newage=' + newage;
if (newage.length < 2) {
$('#Required').fadeIn(300);
$('#Mask').fadeIn(300);
} else {
$.ajax({
type: "POST",
url: "update_age.php",
data: dataString,
cache: false,
success: function (updateage) {
$("#UpdatedAge").empty();
$("#UpdatedAge").append(updateage);
$("#UpdatedAge").show().fadeOut(1200);
}
});
}
}
the problem is you keep appending, change the content instead (just change append to html)
$("#UpdatedAge").html(updateage);
Just use something as
function UpdateAge(Age) {
var newage = $("#NewAge").val();
var dataString = 'newage=' + newage;
if (newage.length < 2) {
$('#Required').fadeIn(300);
$('#Mask').fadeIn(300);
} else {
$.ajax({
type: "POST",
url: "update_age.php",
data: dataString,
cache: false,
success: function (updateage) {
$("#UpdatedAge").html(updateage);
$("#UpdatedAge").show().fadeOut(1200);
}
});
}
}
As .html replaces the content of #UpdatedAge and don't append it to the content, as .append does.
updated my question below
I made a script where a user can import large amounts of data. After the form is submitted and the data validated I add 2 background tasks: 1 is a script that imports all the data. This script also lets the databases know how many in total and how many he has done. The second is a script that reads how much is done from the database and displays it in a nice progress bar.
Code:
$.ajax({
type: "GET",
url: "import-process.php",
success: function(data) {}
});
var process = 0;
var checkPercentage = function() {
$.ajax({
type: "GET",
url: "get-process-status.php",
data: "importcode=123456",
success: function(data) {
if (!data.indexOf("ERROR") !== -1) {
process = data;
$("#process_balk").css('width', process + '%');
}
}
});
if (process != 100) {
setTimeout(checkPercentage, 1000);
} else {
window.location.href = "import-finished.php";
}
}
checkPercentage();
Both scripts, work fine. Except that the second script (getting the status of the process) isn't started after the first (importing the data) is finished. Which makes the complete thing kinda useless.
Any ideas how to solve this?
update:
I found out that the background process gets called only once. That's the problem. I'm just not sure how to fix it..
var checkPercentage = function() {
alert("Is this function getting called every second?");
$.ajax({
type: "GET",
async: true,
url: "required/get-process-status.php",
data: "importcode=123456",
success: function(data) {
alert(data);
}
});
setTimeout(checkPercentage, 1000);
}
The code above alerts "Is this function getting called every second?" every second. Like it should. However, the value 'data' is called only once. That's not what I expected.. Any ideas?
You mean like this?:
$.ajax({
type: "GET",
url: "import-process.php",
success: function(data) {
checkPercentage();
}
});
var process = 0;
var checkPercentage = function() {
$.ajax({
type: "GET",
url: "get-process-status.php",
data: "importcode=123456",
success: function(data) {
if (!data.indexOf("ERROR") !== -1) {
process = data;
$("#process_balk").css('width', process + '%');
}
}
});
if (process != 100) {
setTimeout(checkPercentage, 1000);
} else {
window.location.href = "import-finished.php";
}
}
I just moved checkPercantage function call from end of script to success function of first ajax. You can also move it to complete function if you wish to run it despite of errors.
Set your callback function to be:
success: function(data) {
if (!data.indexOf("ERROR") !== -1) {
process = data;
$("#process_balk").css('width', process + '%');
if (process != 100) {
setInterval(checkPercentage, 1000);
} else {
window.location.href = "import-finished.php";
}
}
}
Firstly, the if statement has to be in a callback function to work the way you want it. Secondly, you should use setInterval() instead of setTimeout() because it will recheck it every interval time.
Also, yabol is right saying that the top of your code should look like this:
$.ajax({
type: "GET",
url: "import-process.php",
success: function(data) {
checkPercentage();
}
});
For some reason ajax is not sending data.
On the PHP I have this code:
if (isset($_POST['submit'])) {
echo "submit";
} else {
echo "not submit";
}
And I get not submit.
This is JS code:
$(function () {
$('#submit').click(function () {
var length = $('#number').val();
var small = $('#small').val();
var big = $('#big').val();
var number = $('#numero').val();
var special = $('#special').val();
var submit = 'submit';
var url = 'public/php/codegenerator.php';
var data = "length=" + length + "&small=" + small + "&big=" + big +
"&number=" + number + "&special=" + special + "&submit=" + submit;
$.ajax({
type: "POST",
url: url,
data: data,
success: function () {
$('#code').load(url, function () {
$(this).fadeIn(1000)
});
}
});
return false;
});
});
You can try this approach
$(function(){
$('#submit').click(function(){
//YOUR CODE
var param = {
length:length,
small:small,
big:big,
number:number,
special:special,
submit:submit
}
$.ajax({
type: "POST",
url: url,
data: param,
//EDITED LINE
success: function (data) {
$('#code').hide().html(data).fadeIn(1000);
}
});
return false;
});
});
// REVISED ANSWER
// IN YOUR PHP FILE
if (isset ($_POST['submit'])) {
echo json_encode(array('result'=>"submit"));
}
else {
echo json_encode(array('result'=>"not submit"));
}
//IN YOUR JQUERY CODE
$.ajax({
type: "post",
url: url,
data: param,
dataType:'json';
//EDITED LINE
success: function (data) {
// alert(data.result);
$('#code').hide().html(data.result).fadeIn(1000);
}
});
You are getting Not submit, because it comes from the .load() call and not from .ajax - and in the load call you just load the URL without passing any POST data. So why you are running .load inside the success callback of .ajax with the same url?
