I have code like this:
var saveToDB;
if ($('.new_article')[0]) {
saveToDB = function() {
var form;
form = $('.new_article');
$.ajax({
url: '/admin/articles',
type: 'POST',
data: form.serialize(),
beforeSend: function(xhr) {
$('.form-status-holder').html('Saving...');
},
success: function(data) {
var jqObj;
jqObj = jQuery(data);
$('.form-status-holder').delay(5000).hide();
}
});
};
$('form input, form textarea').on('input propertychange change', function() {
var timeoutId;
clearTimeout(timeoutId);
return timeoutId = setTimeout((function() {
saveToDB();
}), 5000);
});
return;
} else if ($('.edit_article')[0]) {
saveToDB = function() {
var form, id;
form = $('.edit_article');
id = (form.attr('action')).split("/").pop(-1);
$.ajax({
url: '/admin/articles/' + id,
type: 'POST',
data: form.serialize(),
beforeSend: function(xhr) {
$('.form-status-holder').html('Saving...');
},
success: function(data) {
var jqObj;
jqObj = jQuery(data);
$('.form-status-holder').delay(5000).hide();
}
});
};
$('form input, form textarea').on('input propertychange change', function() {
var timeoutId;
clearTimeout(timeoutId);
return timeoutId = setTimeout((function() {
saveToDB();
}), 5000);
});
return;
}
I got problem with setTimeout function in if condition while it cannot call to saveToDB inside. It takes me hours to find where is the problem come from but now I still get stuck. The second setTimeout function in else condition works correctly. Any help? Thanks in advance.

I have two very similar jquery AJAX codes. Both work correctly when I use them separately. However, if I load the first code, if I want to load the second it probably works (because I tested different places "console.log(''test'')"), but it doesn't change the DOM. Please help.
I have tried many different solutions and none have provided a solution. I have searched on many forums but have not found an answer.
1st
var basketAddTimeout;
var ajaxSubmitForm;
app_shop.run(function() {
ajaxSubmitForm = function() {
$this = $('#projector_button_basket');
var url = $('#projector_form').attr('action');
var txt = $this.text().trim();
clearTimeout(basketAddTimeout);
$.ajax({
type: 'POST',
url: url,
data: $('#projector_form').serializeArray(),
success: function(data) {
basketAddTimeout = setTimeout(function() {
$('#Basket').load(' #projector-basket-form');
}, 1000)
fetch('/ajax/basket.php').then(res => res.json()).then(({
basket
}) => {
const number = basket.productsNumber;
const number12 = basket.worth_formatted;
$('#kwota-basket').text(number12);
document.getElementById('badgekoszyka').style.display = 'block';
$( "#badgekoszyka" ).fadeOut( "slow");
$( "#badgekoszyka" ).fadeIn( "slow");
$('#menu_basket .badge').text(number);
$('#badgekoszyka').text(number);
})
},
error: function() {
classObj.alert(classObj.txt.dodano_produkt_blad);
$('#projector_button_basket').html(txt);
$('#projector_button_basket').removeClass('loader');
}
});
}
}, 'all');
second
var basketAddTimeout2;
var ajaxSubmitForm2;
app_shop.run(function() {
ajaxSubmitForm2 = function() {
var url = $('#projector-basket-form').attr('action');
$('#loaders').addClass('loader-koszyk');
$('#blok-koszyk').css('filter','blur(3px)');
clearTimeout(basketAddTimeout2);
$.ajax({
type: 'POST',
url: url,
data: $('#projector-basket-form').serializeArray(),
success: function(data) {
basketAddTimeout2 = setTimeout(function() {
}, 1000)
fetch('/ajax/basket.php').then(res => res.json()).then(({
basket
}) => {
const number = basket.productsNumber;
const number12 = basket.worth_formatted;
$('#kwota-basket').text(number12);
$('#menu_basket .badge').text(number);
$('#badgekoszyka').text(number);
$('.topBasket').load('/basketchange.php?type=multiproduct&mode=2 .topBasket>*', function() {});
$('#loaders').removeClass('loader-koszyk');
$('#blok-koszyk').css('filter','blur(0px)');
document.getElementById("Basket").innerHTML = contentt;
})
},
error: function() {
classObj.alert(classObj.txt.dodano_produkt_blad);
}
});
}
}, 'all')
$(document).on('click', '#usuwanie-koszyk, #dodawanie-koszyk, #usuwanie-calkowite ', function(e) {
ajaxSubmitForm2();
e.preventDefault();
});
You Should call e.preventDefault() at the priority to defend the default action on the element in the second request.
$(document).on('click', '#usuwanie-koszyk, #dodawanie-koszyk, #usuwanie-calkowite ', function(e) {
e.preventDefault()
ajaxSubmitForm2()
});
Struggling to get this to work properly...Making an if/else statement with setInterval that if class is clicked, content refreshes, else content auto refreshes after a specific time period. This is what I have for just auto refreshing atm (which works perfectly):
var auto_refreshContentTwo = setInterval (
function() {
$('.page_loading_r_content_two_overlay').fadeIn();
$.ajax({
url: '../../path/to/page.php',
success: function(html) {
var myContentTwoContent = $('#refreshContentTwo').html(html).find('#refreshContentTwo2');
$('#refreshContentTwo').html(myContentTwoContent);
}
});
}, 495000
);
What I've tried to get a "click" function added, but doesn't do anything...:
$('.contentTwoClicked').on('click', function() {
var refreshClicked = true;
if(refreshClicked) {
alert('clicked');
$('.page_loading_r_content_two_overlay').fadeIn();
$.ajax({
url: '../../path/to/page.php',
success: function(html) {
var myContentTwoContent = $('#refreshContentTwo').html(html).find('#refreshContentTwo2');
$('#refreshContentTwo').html(myContentTwoContent);
}
});
} else {
var auto_refreshContentTwo = setInterval (
function() {
$('.page_loading_r_content_two_overlay').fadeIn();
$.ajax({
url: '../../path/to/page.php',
success: function(html) {
var myContentTwoContent = $('#refreshContentTwo').html(html).find('#refreshContentTwo2');
$('#refreshContentTwo').html(myContentTwoContent);
}
});
}, 495000
);
}
});
Where am I going wrong? Or am I way off-base here...? Any guidance/help would be greatly appreciated!
You don't need a conditional statement, but rather a variable to store the set interval in so that it can be cleared and restarted on manual refresh via a calling function:
//variable to store the setInterval
let refreshInterval = '';
//function that calls setInterval
const autoRefresh = () => {
refreshInterval = setInterval(()=> {
refresh();
console.log("auto");
},3000)
}
//run setInterval function on page load;
autoRefresh();
//manual refresh function
const manualRefresh = () => {
//erases the setInterval variable
clearInterval(refreshInterval);
refresh();
//then recalls it to reset the countdown
autoRefresh();
console.log("manual");
}
//for visual purposes
let refreshCount = 0;
//node refresher function
const refresh = () => {
const container = document.getElementById("refresh");
refreshCount ++;
container.textContent= "This div will be refreshed"+ ` Refresh Count: ${refreshCount}`;
}
<button onclick="manualRefresh()">Click to Refresh </button>
<div id="refresh">This div will be refreshed</div>
See it in action: https://codepen.io/PavlosKaralis/pen/rNxzZjj?editors=1111
Edit: Applied to your code I think it would be:
let interval;
var autoRefresh = () => {
interval = setInterval (
function() {
$('.page_loading_r_content_two_overlay').fadeIn();
$.ajax({
url: '../../path/to/page.php',
success: function(html) {
var myContentTwoContent = $('#refreshContentTwo').html(html).find('#refreshContentTwo2');
$('#refreshContentTwo').html(myContentTwoContent);
}
});
}, 495000);
}
$('.contentTwoClicked').on('click', function() {
clearInterval(interval);
alert('clicked');
$('.page_loading_r_content_two_overlay').fadeIn();
$.ajax({
url: '../../path/to/page.php',
success: function(html) {
var myContentTwoContent = $('#refreshContentTwo').html(html).find('#refreshContentTwo2');
$('#refreshContentTwo').html(myContentTwoContent);
}
});
autoRefresh();
});
autoRefresh();
I am currently using a keyup function to initiate my autosave.php file which auto saves information to a table. However, I am starting to find that the keyup seems to be inefficient due to fast typing and submitting long strings.
How can I have the ajax submit every x seconds, instead of each keyup after so many ms?
$(document).ready(function()
{
// Handle Auto Save
$('.autosaveEdit').keyup(function() {
delay(function() {
$.ajax({
type: "post",
url: "autosave.php",
data: $('#ajaxForm').serialize(),
success: function(data) {
console.log('success!');
}
});
}, 500 );
});
});
var delay = (function() {
var timer = 0;
return function(callback, ms) {
clearTimeout (timer);
timer = setTimeout(callback, ms);
};
})();
Solution
Use setInterval It is like setTimeout but repeats itself.
setInterval(function () {
$.ajax({
type: "post",
url: "autosave.php",
data: $('#ajaxForm').serialize(),
success: function(data) {
console.log('success!');
}
});
}, 1000);
Optimization
turn it on when the control has focus and turn it off when focus leaves. Also poll for the form data if it has updated then send the ajax request otherwise ignore it.
var saveToken;
var save = (function () {
var form;
return function () {
var form2 = $('#ajaxForm').serialize();
if (form !== form2) { // the form has updated
form = form2;
$.ajax({
type: "post",
url: "autosave.php",
data: form,
success: function(data) {
console.log('success!');
}
});
}
}
}());
$('.autosaveEdit').focus(function() {
saveToken = setInterval(save, 1000);
});
$('.autosaveEdit').focusout(function() {
clearInterval(saveToken);
save(); // one last time
});
I believe that what you are looking for is the window.setInterval function. It's used like this:
setInterval(function() { console.log('3 seconds later!'); }, 3000);
Use setInterval
function goSaveIt()
{
$.ajax({
type: "post",
url: "autosave.php",
data: $('#ajaxForm').serialize(),
success: function(data) {
console.log('success!');
}
});
}
setInterval(goSaveIt, 5000); // 5000 for every 5 seconds
I have a submit button on page index.php When i click this button another script (call.php) is called through ajax that holds some response. Now i want that time between the click of submit button and response displayed/received under a div through the call of ajax script the buttons option1 and option2 should get disabled. and when succesfully the result is dispalyed the 2 buttons should get enabled, however i am not able to do so. can anyone help me with it
3 buttons and script code on index.php page is
<button class="rightbtn" type="button" id="submitamt" style="display:none; ">Submit</button>
<button class="botleftbtn" type="button" id="walkaway" style="display:none">Option1</button>
<button class="botrightbtn" type="button">Option2</button>
<script>
function myFunction() {
alert("You need to login before negotiating! However you can purchase the product without negotiating");
}
var startClock;
var submitamt;
var walkaway;
var digits;
$(function() {
startClock = $('#startClock').on('click', onStart);
submitamt = $('#submitamt').on('click', onSubmit);
walkaway = $('#walkaway').on('click', onWalkAway);
digits = $('#count span');
beforeStart();
});
var onStart = function(e) {
startClock.fadeOut(function() {
startTimer();
submitamt.fadeIn(function() {
submitamt.trigger('click'); // fire click event on submit
});
walkaway.fadeIn();
});
};
var onSubmit = function(e) {
var txtbox = $('#txt').val();
var hiddenTxt = $('#hidden').val();
$.ajax({
type: 'post',
url: 'call.php',
dataType: 'json',
data: {
txt: txtbox,
hidden: hiddenTxt
},
cache: false,
success: function(returndata) {
$('#proddisplay').html(returndata);
},
error: function() {
console.error('Failed to process ajax !');
}
});
};
var onWalkAway = function(e) {
//console.log('onWalkAway ...');
};
var counter;
var timer;
var startTimer = function() {
counter = 120;
timer = null;
timer = setInterval(ticker, 1000);
};
var beforeStart = function() {
digits.eq(0).text('2');
digits.eq(2).text('0');
digits.eq(3).text('0');
};
var ticker = function() {
counter--;
var t = (counter / 60) | 0; // it is round off
digits.eq(0).text(t);
t = ((counter % 60) / 10) | 0;
digits.eq(2).text(t);
t = (counter % 60) % 10;
digits.eq(3).text(t);
if (!counter) {
clearInterval(timer);
alert('Time out !');
resetView();
}
};
var resetView = function() {
walkaway.fadeOut();
submitamt.fadeOut(function() {
beforeStart();
startClock.fadeIn();
});
};
</script>
You can achieve this by disabling the buttons before you make the AJAX request, and then enabling them again in the complete handler of the request. Try this:
var onSubmit = function(e) {
var txtbox = $('#txt').val();
var hiddenTxt = $('#hidden').val();
$('.botleftbtn, .botrightbtn').prop('disabled', true); // < disable the buttons
$.ajax({
type: 'post',
url: 'call.php',
dataType: 'json',
data: {
txt: txtbox,
hidden: hiddenTxt
},
cache: false,
success: function(returndata) {
$('#proddisplay').html(returndata);
},
error: function() {
console.error('Failed to process ajax !');
},
complete: function() {
$('.botleftbtn, .botrightbtn').prop('disabled', false); // < enable the buttons
}
});
};
Note that its best to enable the buttons in the complete handler and not the success handler. This is because if there is an error the buttons will never be enabled again.
Disable the buttons on click, and enable them on ajax success:
var onSubmit = function(e) {
var txtbox = $('#txt').val();
var hiddenTxt = $('#hidden').val();
//Disable buttons ---------------------- //
//Give an id to the second button
$('#walkaway, #the_other_button').prop('disabled', true);
$.ajax({
type: 'post',
url: 'call.php',
dataType: 'json',
data: {
txt: txtbox,
hidden: hiddenTxt
},
cache: false,
success: function(returndata) {
$('#proddisplay').html(returndata);
//Enable buttons ---------------------- //
$('#walkaway, #the_other_button').prop('disabled', false);
},
error: function() {
console.error('Failed to process ajax !');
}
});
};
In your onsubmit() code, get a var reference to the buttons you wish to deactivate
Var btn1 = document.getElementbyId("btn1");
But you would have to set an Id for the two buttons.
You can disable these in your submit code and then enable them when your timer is done.
Btn1.disabled = true;
When your timer is done, set it as false the same way.
I recently began learning Ajax and jQuery. So yesterday I started to programm a simple ajax request for a formular, that sends a select list value to a php script and reads something out of a database.
It works so far!
But the problem is, that when I click on the send button, it starts the request, 1 second later. I know that it has something to do with my interval. When I click on the send button, I start the request and every second it requests it also, so that I have the opportunity, to auto-refresh new income entries.
But I'd like to have that interval cycle every second, but the first time I press the button it should load immediately, not just 1 second later.
Here is my code:
http://jsbin.com/qitojawuva/1/edit
$(document).ready(function () {
var interval = 0;
$("#form1").submit(function () {
if (interval === 0) {
interval = setInterval(function () {
var url = "tbladen.php";
var data = $("#form1").serialize();
$.ajax({
type: "POST",
url: url,
data: data,
success: function (data) {
$("#tbladen").html(data);
}
});
}, 1000);
}
return false;
});
});
Thanks!
I might be something like the following you're looking for.
$(document).ready(function () {
var isFirstTime = true;
function sendForm() {
var url = "tbladen.php";
var data = $("#form1").serialize();
$.ajax({
type: "POST",
url: url,
data: data,
success: function (data) {
$("#tbladen").html(data);
}
});
}
$("#form1").submit(function () {
if (isFirstTime) {
sendForm();
isFirstTime = false;
} else {
setTimeout(function () {
sendForm();
}, 1000);
}
return false;
});
});
So, use setTimeout when the callback has finished as setInterval just keeps running whether or not your callback has finished.
$(function () {
$("#form1").submit(postData);
function postData() {
var url = "tbladen.php",
data = $("#form1").serialize();
$.ajax({
type: "POST",
url: url,
data: data,
success: function (data) {
$("#tbladen").html(data);
setTimeout(postData, 1000);
}
});
return false;
}
});
