How To Set This ajax Run Every 5 Second
$(document).ready(function() {
var SrNo = document.getElementById('EntryType').value;
var EntryType = document.getElementById('EntryType').value;
$.ajax({
type: "POST",
url: "get_max_srno.php?CID=" + SrNo + "&EntryType=" + EntryType,
data: {
SrNo: $("#EntryType option:selected").val()
},
data: {
EntryType: $("#EntryType option:selected").val()
}
})
.done(function(msg1) {
var msg = msg1;
document.getElementById('SrNo').value = msg1;
});
});
function autoCall(){
var feedback = $.ajax({
type: "POST",
url: "autocall.php",
async: false
}).success(function(){
setTimeout(function(){autoCall();}, 5000);
}).responseText;
$('div').html(feedback);
}
if you want it to run only after successfully completing the call,
you can set it up in your .ajax().success() callback:
Or use .ajax().complete() if you want it to run regardless of result:
here is the demo explaining success() and complete().
here complete() will fire every 5 seconds as success is returning 404.
Hope this will be interesting everyone who looking this kind of problem.
Working Demo
You can use setInterval function.
For reference
https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setInterval
var reloadContent = function () {
var SrNo = document.getElementById('EntryType').value;
var EntryType = document.getElementById('EntryType').value;
$.ajax({
type: "POST",
url: "get_max_srno.php?CID=" + SrNo + "&EntryType=" + EntryType,
data: {
SrNo: $("#EntryType option:selected").val()
},
data: {
EntryType: $("#EntryType option:selected").val()
}
})
.done(function(msg1) {
var msg = msg1;
document.getElementById('SrNo').value = msg1;
});
}
$(document).ready(function() {
var reloadContentInterval = setInterval(reloadContent, 5000);
// You can cancel it later if you want
// clearInterval( reloadContentInterval );
});

My ajax call is returning zero even though I wrote die() at the end of my PHP function.
I looked over the other questions here and did not figure it out, please take a look at my code
I make an ajax call using this function:
$('.aramex-pickup').click(function() {
var button = $(this);
var pickupDateDate = $('.pickup_date').val();
var pickupDateHour = $('.pickup_date_hour').val();
var pickupDateMinute = $('.pickup_date_minute').val();
var pickupDate = pickupDateDate + ' ' + pickupDateHour + ':' + pickupDateMinute;
var orderId = button.data('id');
if (pickupDate) {
//show loader img
button.next('.ajax-loader').show();
var data = {
'action': 'aramex_pickup',
'order_id': orderId,
'pickup_date': encodeURIComponent(pickupDate)
};
$.ajax({
url: ajaxurl,
data: data,
type: 'POST',
success: function(msg) {
console.log(msg);
if (msg === 'done') {
location.reload(true);
} else {
var messages = $.parseJSON(msg);
var ul = $("<ul>");
$.each(messages, function(key, value) {
ul.append("<li>" + value + "</li>");
});
$('.pickup_errors').html(ul);
}
}, complete: function() {
//hide loader img
$('.ajax-loader').hide();
}
});
} else {
alert("Add pickup date");
}
return false;
});
in the back-end I wrote this function just to test the ajax is working ok:
public function ajax_pickup_callback() {
echo 'ajax done';
die();
}
I registered the action by:
add_action('wp_ajax_aramex_pickup', array($this, 'ajax_pickup_callback'));
all of this returns 0 instead of "ajax done".
Any help please?
Actually your hook is not get executed. You have to pass the action in the ajax request as you can see here.
jQuery.post(
ajaxurl,
{
'action': 'add_foobar',
'data': 'foobarid'
},
function(response){
alert('The server responded: ' + response);
}
);
I have an ajax request, whereby I am installing a magento shop automatically, and when the process is done, it would redirect the user to the newly created shop. Here are my codes:
function postSuccessFormData() {
var targetUrl = '/index.php/install/wizard/successPost';
jQuery('.form-button').addClass('loading');
setInterval(installStatus(),4000);
jQuery.ajax({
url: targetUrl,
global: false,
type: 'POST',
data: ({
finish: 1,
password_key: jQuery('#password_key').val()
}),
async: true,
dataType: 'json',
error: function() {
alert("An error has occurred. Please try again.");
},
success: function(data) {
window.location.href = '/';
}
});
function installStatus() {
var installerUpdatesUrl = '/index.php/install/wizard/installerStatus';
//showProgressBar();
jQuery.ajax({
url: installerUpdatesUrl,
// global: false,
type: 'GET',
async: true,
dataType: 'json',
error: function (data) {
// alert(data.result);
},
success: function (data) {
handle data.result
var dataKeys = Object.keys(data);
var lastElementKey = dataKeys[dataKeys.length - 1];
var lastMessage = data[lastElementKey]['message'];
if(data[lastElementKey]['progress'] == '') {
updateProgressBar(data[dataKeys[dataKeys.length - 2]]['progress'],100);
}
setting message
jQuery("#message").html(lastMessage);
if (data[lastElementKey]['state'] == 'Failure') {
var stepStr = lastElementKey.split('_');
var stepString = stepStr[0].toUpperCase() + ' ' + stepStr[1] + ':';
alert(stepString + "\n" + data[lastElementKey]['message']);
//hideProgressBar();
jQuery('.form-button').removeClass('loading');
return false;
} else if (data[lastElementKey]['state'] == 'Finish') {
alert(data[lastElementKey]['message']);
//hideProgressBar();
jQuery('.form-button').removeClass('loading');
//window.location.href = '/';
} else {
// installStatus();
}
},
complete: function () {
installStatus();
jQuery('.form-button').removeClass('loading');
}
});
}
The way this is done:
After every 4 seconds the function installStatus is run, which will output the current progress in JSON format. My problem is, this function needs to be executed simultaneously with the function post().
This is not happening, the installStatus is only run after the first function has been completed.
What is wrong?
You are executing installStatus when you define it. So this:
setInterval(installStatus(),4000);
needs to be
setInterval(installStatus, 4000);
The new XMLHttpRequest has a nice progress event you can listen to show the user the upload progress.
Here's the spec with a nice demo: https://developer.mozilla.org/en/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest#Monitoring_progress
Initially you should call installStatus() only once and then inside the method inside ajax success you should update the procent in the progress bar and call it recursively the same method. On the server side you can save the current procent in a cookie and with every recursive call you can update the cookie and return the procent.
I'm having troubles using a global variable in my ajax response.
LastDate is a variable defined in the page I loaded into my second page. (function load_table)
I am able to acces the variable before the ajax call, but I can't seem to acces it in my ajax succes. because it gives undefined. <==== in code
my code:
var dia_date = {};
$(window).load(function()
{
DP("eerste keer")
load_table();
} );
function load_table()
{
DP('load_table');
$.ajax({
type: "POST",
url: "/diagnose_hoofdpagina/table_diagnose/" + DosierID,
success: function (data) {
$("#diagnoses_zelf").html('');
$("#diagnoses_zelf").append(data).trigger('create');
//initialize_table();
update_table();
},
error: function(){
alert('error');
}
});
return false;
}
function update_table()
{
if(LastDate > Datum)
{
alert("LasteDate" + LasteDate);
}
else
{
alert("Datum" + Datum);
}
alert('gast .... ' + LastDate); // <========== this is promted on the screen so there is no problem
$.ajax({
type: "POST",
url: "/refresh_diagnose/" + DosierID,
dataType: "json",
data : JSON.stringify(dia_date),
success: function (data) {
var DataDate = new Date(data.Year, data.Month, data.Day, data.Hour, data.Minute, data.Second);
alert('lastdate :'+ LastDate + 'date.date :' + DataDate);
//<============ BUT HERE HE GIVES LastDate AS UNDEFINED
},
error: function(data){
alert(data);
}
});
return false;
}
I can't see what I'm doing wrong. Can annyone help me plaese ? Thanks in advance.
You can try making a function.
var lastDate = #;
function getLastDate(){return lastDate;}
ajax.blablabla.success :{getLastDate();}
I have 2 elements on my page that I am trying to reload via ajax - however I can only ever seem to update one. Below is my code,
$('#messages_send').live('click', function() {
$.ajax({
url: base_url + 'ajax/send_message',
data: {
username: $('#messages_username').val(),
message: $('#messages_message').val(),
saveid: $('#messages_savedid').val(),
},
success: function(data) {
sending_message();
var x = jQuery.parseJSON(data);
if(x) {
if(x.gp_id==80)
{
$('#spn_ucredit').load(base_url + 'ajax/userdata/credits');
$('#overlay_credits').load(base_url + 'ajax/userdata/credits');
}
}
//$('#spn_ucredit').html($('#ncd_id').val());
//tmp_cost = $('#spn_ucredit').html()-$('#ncd_id').val();
//$('#ncd_id').val($('#ncd_id').val()-tmp_cost);
//alert(data);
setTimeout(message_sent, 2000);
setTimeout(remove_modal_box, 3000);
setTimeout(message_revert, 3500);
$("#saved_messages").load(base_url + 'messages #saved_messages > form');
$("#messages_content").load(base_url + 'messages #messages_content > form');
}
});
return false;
});
Am I doing something wrong?
sico,
There's a number of things you can do to debug/improve the code, chief amongst which is to reduce the number of HTTP requests. With $.get() instead of .load(), it should be possible to use the HTTP responses twice each.
Something like this :
$(document).on('click', '#messages_send', function() {
sending_message();
$.ajax({
url: base_url + 'ajax/send_message',
data: {
username: $('#messages_username').val(),
message: $('#messages_message').val(),
saveid: $('#messages_savedid').val(),
},
dataType: 'json',
success: function(data) {
var creditsPromise, messagesPromise;//vars that allow .when() later.
if(data.gp_id == 80) {
creditsPromise = $.get(base_url + 'ajax/userdata/credits', function(data) {
$('spn_ucredit').html(data);
$('#overlay_credits').html(data);
});
}
else {
creditsPromise = (new $.Deferred()).resolve().promise();
}
messagesPromise = $.get(base_url + 'messages', function(data) {
var $data = $(data);
$("#saved_messages").empty().append($data.find('#saved_messages > form'));
$("#messages_content").empty().append($data.find('#messages_content > form'));
});
$.when(creditsPromise, messagesPromise).done(function() {//fires when both $.get()s have successfully responded
message_sent();
setTimeout(remove_modal_box, 1000);
setTimeout(message_revert, 1500);
});
}
});
return false;
});
This reduces the number of HTTP requests from five to three.
You could further reduce the number of HTTP requests to one, though you would need to write a server-side script to perform everything currently performed by ...ajax/send_message, ...ajax/userdata/credits and ...messages, and json-encode a composite response.
The client-side code could then simplify to something like this:
$(document).on('click', '#messages_send', function() {
sending_message();
$.ajax({
url: base_url + 'ajax/send_message',
data: $("#messages form").serialize(),//assumed
dataType: 'json',
success: function(data) {
if(data.gp_id == 80) {
$('#spn_ucredit').html(data.credits);
$('#overlay_credits').html(data.credits);
}
$("#saved_messages").html(data.saved_messages);
$("#messages_content").html(data.messages_content);
message_sent();
setTimeout(remove_modal_box, 1000);
setTimeout(message_revert, 1500);
}
});
return false;
});
For some reason, my script isn't writing out the text after I remove the textbox element. Am I incorrectly using the .html or is something else wrong?
$('.time').click(function () {
var valueOnClick = $(this).html();
$(this).empty();
$(this).append("<input type='text' class='input timebox' />");
$('.timebox').val(valueOnClick);
$('.timebox').focus();
$('.timebox').blur(function () {
var newValue = $(this).val();
var dataToPost = { timeValue: newValue };
$(this).remove('.timebox');
if (valueOnClick != newValue) {
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
alert(msg);
$(this).html("88");
}
});
} else {
// there is no need to send
// an ajax call if the number
// did not change
alert("else");
$(this).html("88");
}
});
});
OK, thanks to the comments, I figured out I was referencing the wrong thing. The solution for me was to change the blur function as follows:
$('.timebox').blur(function () {
var newValue = $(this).val();
var dataToPost = { timeValue: newValue };
if (valueOnClick != newValue) {
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
}
});
} else {
// there is no need to send
// an ajax call if the number
// did not change
}
$(this).parent().html("8");
$(this).remove('.timebox');
});
$(this) in your success handler is refering to msg, not $('.timebox') (or whatever element that you want to append the html to)
$(this) = '.timebox' element but you have removed it already,
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
alert(msg);
$(this).html("88"); // This = msg
}
and
else {
// there is no need to send
// an ajax call if the number
// did not change
alert("else");
$(this).html("88"); // this = '.timebox' element but you have removed it already,
}
The value of this changes if you enter a function. So when u use this in the blur function handler, it actually points to '.timebox'
$('.time').click(function () {
var valueOnClick = $(this).html();
var $time=$(this);//If you want to access .time inside the function for blur
//Use $time instead of$(this)
$(this).empty();
$(this).append("<input type='text' class='input timebox' />");
$('.timebox').val(valueOnClick);
$('.timebox').focus();
$('.timebox').blur(function () {
var newValue = $(this).val();
var dataToPost = { timeValue: newValue };
$(this).remove(); //Since $(this) now refers to .timebox
if (valueOnClick != newValue) {
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
alert(msg);
$(this).html("88");
}
});
} else {
// there is no need to send
// an ajax call if the number
// did not change
alert("else");
$(this).html("88");
}
});
});
