AJAX is not working in macOS WebView

I have created a WebView for macOS app and it contains one AJAX call. The same WebView is working fine when the app calls my local URL, but when it calls the live URL, the AJAX call is not working.
$(document).ready(function () {
$('#pripolcheck').click(function () {
var pripolcheck = $('#pripolcheck').val();
var app = $('#app').val();
var user_id = $('#user_id').val();
var contact = $('#contact').val();
// Returns successful data submission message when the entered information is stored in database.
var dataString = 'pripolcheck1=' + pripolcheck + '&app1=' + app + '&user_id1=' + user_id;
if (pripolcheck == '') {
alert('Please Fill All Fields');
} else {
// AJAX Code To Submit Form.
$.ajax({
type: 'POST',
url: 'http://mywebsite.com/ajaxformsubmit.php',
data: dataString,
cache: false,
success: function (result) {
// alert(result);
// $(".pripol").hide();
$('.pripolcheck').prop('checked', true);
$('input.pripolcheck').attr('disabled', true);
}
});
}
return false;
});
});
My local PHP version is 7.1.8 and my live server PHP version is 5.4.

Change your function to onclick of checkbox directly,put this code in your checkbox onclick="MyFuncion",why I'm telling this is for web view we need to give exact command in exact position it's not a browser
And your AJAX call will be like below,
function myFunction()
{
var pripolcheck = $("#pripolcheck").val();
var app = $("#app").val();
var user_id = $("#user_id").val();
var contact = $("#contact").val();
// Returns successful data submission message when the entered information is stored in database.
var dataString = 'pripolcheck1='+ pripolcheck + '&app1='+ app + '&user_id1='+ user_id;
if(pripolcheck=='')
{
alert("Please Fill All Fields");
}
else
{
// AJAX Code To Submit Form.
$.ajax({
type: "POST",
url: "ajaxformsubmit.php",
data: dataString,
cache: false,
success: function(result){
// alert(result);
// $(".pripol").hide();
$('.pripolcheck').prop('checked', true);
$("input.pripolcheck").attr("disabled", true);
}
});
}
return false;
}

"My local PHP version is 7.1.8 and my live server PHP version is 5.4."
I think this explains everything.
However, try setting an absolute URL in your call:
url: 'ajaxformsubmit.php',
to
url: '/ajaxformsubmit.php',
Or whatever the actual path would be. Just a single slash will give you
http://wherever.com/ajaxformsubmit.php

if u use same site url plz use relative path not absolute path then its ok.
if use defrant site url plz comment me so give me new solution
PLZ try
$(document).ready(function () {
$('#pripolcheck').click(function () {
var pripolcheck = $('#pripolcheck').val();
var app = $('#app').val();
var user_id = $('#user_id').val();
var contact = $('#contact').val();
// Returns successful data submission message when the entered information is stored in database.
var dataString = 'pripolcheck1=' + pripolcheck + '&app1=' + app + '&user_id1=' + user_id;
if (pripolcheck == '') {
alert('Please Fill All Fields');
} else {
// AJAX Code To Submit Form.
$.ajax({
type: 'POST',
url: '/ajaxformsubmit.php',
data: dataString,
cache: false,
success: function (result) {
// alert(result);
// $(".pripol").hide();
$('.pripolcheck').prop('checked', true);
$('input.pripolcheck').attr('disabled', true);
}
});
}
return false;
});
});

The form dont include the + sign, that i write

This code will submit the information from the form to a php file, everything works as it should, but when i write "hello this a text + - * " it remove the " + " sign from what i wrote, always. I dont know why, please help me out guys
$(document).ready(function(){
$("form#submit").submit(function() {
// we want to store the values from the form input box, then send via ajax below
var fname = $('#fname').attr('value');
var lname = $('#lname').attr('value');
$.ajax({
type: "POST",
url: "Mail.php",
data: "fname="+ fname + "&lname=" + lname,
success: function(){
$('form#submit').show();
//$('form#submit :input').val("");
$('div.success').fadeIn();
}
});
return false;
});
});

Change this line:
data: "fname="+ fname + "&lname=" + lname,
to:
data: "fname="+ encodeURIComponent(fname) + "&lname=" + encodeURIComponent(lname),
You need to escape special characters for use in URL strings.

if fname and lname are text boxes, why not use the .val() to retrieve them?
var fname = $('#fname').val();
var lname = $('#lname').val();
or better, use form .serialize() directly on the ajax:
$(function () {
$("form#submit").submit(function () {
var form = $(this)
$.ajax({
type: "POST",
url: "Mail.php",
data: form.serialize() //turns the form data into a query string
success: function () {
$('form#submit').show();
$('div.success').fadeIn();
}
});
return false;
});
});

That's because the pluses are converted to spaces. Use encodeURIComponent to escape the input. Always use some kind of escaping to avoid injections.

Or you could use serialize():
$.ajax({
...
data: $(this).serialize()
...
});
This takes all the :input elements inside your form and encodes them properly for sending to a remote server. You could also do this:
data: {
fname: fname,
lname: lname
}
jQuery understands that you're trying to send an array of values and will automatically escape it.
Btw, this is not very portable:
var fname = $('#fname').attr('value');
The better way is this:
var fname = $('#fname').val();

var email = $('#email').val();
var data = 'email=' + encodeURIComponent(email);
var url = 'test.php'
var type = 'post'
var success = function(output){}
var error = function(){}
$.ajax({
url:url,
type:type,
data:data,
success:success,
error:error
});
work great for me

Ajax success function issue

My javascript looks like that.
There are some problems that I can't figure out, where I did mistake
#status_message doesn't show generated message
$("#status").className = 'fail'; doesn't override current class
var message=$("#status_message"), form=$("#bcscan"), ids=$('#itemids'),proctype, destination, counter=0, tenWordCounter = 0, autoPostInterval=null, errorcount=0, successcount=0;
function ajaxPost() {
formData = form.serialize()+'&process=Scan';
formUrl = form.attr('action');
formMethod = form.attr('method');
$.ajax({
url: formUrl,
type: formMethod,
dataType: "json",
data: formData,
success: function (data) {
var now = new Date();
if(data.err_detected==="yes")
{
if(data.errors.indexOf(",") != -1)
errorcount=errorcount+data.errors.split(",").length;
else errorcount=errorcount+1;
$("#status").className = 'fail';
message =errorcount+" errors found";
$('#errors').prepend(data.errors).slideDown("slow");
}
$('#success').prepend(data.success).slideDown("slow");
if(data.success.indexOf(",") != -1)
successcount=successcount+data.errors.split(",").length;
else successcount=successcount+1;
message +="Last submitted:"+now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds();
$("#status_message").text(message);
}
});
}
Here is page in action
If you want to test, please choose some option from selects like, output from db, ebay.fr and press "scan". Enter 10 digits seperated by comma try 41,42 (they exist in db tables) too between them. After 10th digit it will post textarea via ajax.

For the message, you've declared a jQuery object pointing at the element:
var message = $('#status_message'), ...
but then you're overwriting it with a string:
message = errorcount + ' errors found';
You should be calling:
message.text('some string...')
to change its contents.
For the class change, the correct syntax is:
$("#status").addClass('fail');

How about
$('#status').attr('class','fail');
This will override the current class.

did you try this?? $("#status").addClass( 'fail');

ajax success callback not working

So I have this JavaScript which works fine up to the $.ajax({. Then it just hangs on the loader and nothing happens.
$(function() {
$('.com_submit').click(function() {
var comment = $("#comment").val();
var user_id = $("#user_id").val();
var perma_id = $("#perma_id").val();
var dataString = 'comment='+ comment + '&user_id='+ user_id + '&perma_id=' + perma_id;
if(comment=='') {
alert('Please Give Valid Details');
}
else {
$("#flash").show();
$("#flash").fadeIn(400).html('<img src="ajax-loader.gif" />Loading Comment...');
$.ajax({
type: "POST",
url: "commentajax.php",
data: dataString,
cache: false,
success: function(html){
alert('This works');
$("ol#update").append(html);
$("ol#update li:first").fadeIn("slow");
$("#flash").hide();
}
});
}
return false;
});
});

Try replacing:
var dataString = 'comment='+ comment + '&user_id='+ user_id + '&perma_id=' + perma_id;
with:
var dataString = { comment: comment, user_id: user_id, perma_id: perma_id };
in order to ensure that the parameters that you are sending to the server are properly encoded. Also make sure that the commentajax.php script that you are calling works fine and it doesn't throw some error in which case the success handler won't be executed and the loader indicator won't be hidden. Actually the best way to hide the loading indicator is to use the complete event, not the success. The complete event is triggered even in the case of an exception.
Also use a javascript debugging tool such as FireBug to see what exactly happens under the covers. It will allow you to see the actual AJAX request and what does the the server respond. It will also tell you if you have javascript errors and so on: you know, the kinda useful stuff when you are doing javascript enabled web development.

Post Forms Using Javascript URL

I'm trying to submit a form to a website not my own (salesforce.com with their web-to-lead function) and I'm doing it through a javascript modal window.
Basically once all the entries are tested and made sure there are no errors, I use this:
if(error_count == 0) {
$.ajax({
type: "POST",
url: "[salesforce url]",
data: "first_name=" + first_name + "&last_name=" + last_name + "&email=" + email + "&firm=" + firm + "&[salesforceid]=" + AUM + "&[salesforceid]=" + custodian + "&[salesforceid]=" + custodian_other,
error: function() {
$('.error').hide();
$('#sendError').slideDown('slow');
},
success: function () {
$('.error').hide();
$('.success').slideDown('slow');
$('form#callToAction').fadeOut('slow');
}
});
}
If tested the form without using javascript and the url works, so I'm thinking maybe the way javascript handles the url is the issue?
The issue: the data is not getting successfully submitted to Salesforce. Again, regular HTML form works, javascript doesn't. So I've identified it as a javascript issue.

You cannot make a XHR cross domain request unless the receiving server has allowed it and the browser supports CORS. You can however do a blind submit like this which will assume success:
var $form = $("<form>", {
method: "POST",
action: "[salesforce url]",
target: "my-iframe"
}).appendTo("body");
var $iframe = $("<iframe>", {
name: "my-iframe"
}).bind( "load", function () {
$('.error').hide();
$('.success').slideDown('slow');
$('form#callToAction').fadeOut('slow');
$iframe.remove();
$form.remove();
}).appendTo("body");
$.each(("first_name=" + first_name + "&last_name=" + last_name + "&email=" + email + "&firm=" + firm + "&[salesforceid]=" + AUM + "&[salesforceid]=" + custodian + "&[salesforceid]=" + custodian_other).split("&")), function (index, value) {
var pair = value.split("=");
$form.append("<input>", {
type: "hidden",
name: pair[0],
value: pair[1]
});
});
$form.submit();

+1 for Jim Jose. This sort of thing could be interpreted as an XSS attack against the user, so most likely the browser will not allow it.
You could check out your browser's error logs, see if there's any security errors when you try to run your script. If that doesn't do anything, try to install a tool like Firebug and see if it can pinpoint the problem.
You could also improve your error handling by trying a different sort of method signature for the error function, like this:
error: function(jqXHR, textStatus, errorThrown) {...}
This way you can check what sort of error is being thrown from the Ajax call.
