i made an ajax website that call php pages from a /pages folder inside my index.php, inside my page painting.php i have a link that call painting-slider.php page.
so how can i open this painting-slider.php in ajax when i already called my painting.php page?
this is my index.php request page:
<div id="ajax-container">
<?php
$d = "pages/";
if (isset($_GET['p'])) {
$p = strtolower($_GET['p']);
if (preg_match("/^[a-z0-9\-]+$/", $p) && file_exists($d . $p . ".php")) {
include $d . $p . ".php";
} else {
include $d . "404.php";
}
} else {
include $d . "home.php";
}
?>
</div>
and this is my ajax function:
var afficher = function(data, page) {
$('#ajax-container').fadeOut(250, function() {
$('#ajax-container').empty();
$('#ajax-container').append(data);
$('#ajax-container').fadeIn(100, function() {});
});
};
var lastRequest = null;
if (lastRequest !== null) {
lastRequest.abort();
}
var loadPage = function(page, storeHistory) {
if (typeof storeHistory === 'undefined') {
storeHistory = true;
}
lastRequest = $.ajax({
url: "pages/" + page,
cache: false,
success: function(html) {
afficher(html, page);
if (storeHistory === true) {
history.pushState({
'key': 'value',
'url': page
}, '', page);
}
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
afficher('erreur lors du chagement de la page');
}
});
return false;
};
window.addEventListener('load', function() {
setTimeout(function() {
window.addEventListener('popstate', function(e) {
if (e.state === null) {
loadPage('home.php');
} else {
loadPage(e['state']['url'], false);
}
});
}, 0);
});
$('.link').bind('click', function(e) {
e.preventDefault();
var page = $(this).attr('href');
loadPage(page);
return false;
});
a simple example of "ajax after ajax":
$.ajax({
url: "pages/" + page,
cache: false,
success: function(html) {
afficher(html, page);
if (storeHistory === true) {
history.pushState({
'key': 'value',
'url': page
}, '', page);
}
$.ajax({
url: otherUrl,
cache: false,
success: function(result) {
alert("i am the second result");
alert(result);
}
});
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
afficher('erreur lors du chagement de la page');
}
});
On the serverside (your PHP files) it is not important to do anything. Your ajax will just get the return value of the script found at the given Urls. I hope it helps

How can I show "success" up on Console screen? In a nutshell, I want to show on Console the erros that I forced to happen in a register formulary.
function getRoot() {
var root = "http://" + document.location.hostname + "/login_AMUBA/";
return root;
}
$("#formCadastro").on("submit", function (event) {
event.preventDefault();
var dados = $(this).serialize();
function response() {
return $.ajax({
url: getRoot() + 'controllers/controllerCadastro',
type: 'post',
dataType: 'json',
data: dados,
success: function (response) {
console.log(response);
}
});
}
if (response) {
console.log(success);<--Here
}
});
Finally, the final function (on a php file) should show the error(errors) on console screen, but only "else" works (when it is not commented)
public function validateFinalCad($arrVar)
{
if (count($this->getErro()) > 0) {
$arrResponse = [
"retorno" => "erro",
"erros" => $this->getErro()
];
} else {
/*$this->cadastro->insertCad($arrVar);*/
}
return json_encode($arrResponse);
}
Hi Have a ajax call in a function thats called on date input change event to check if a date is already in use for User. the success in the Ajax call fires after the click function is finished.
How do I get the success results and continue on with the #datepicker change funtion as I need the json results for rest of function.
controller
public ActionResult IsDateAvailable(DateTime date, int Id) {
var dateAvailable = !(_context.Trading.Any(t => t.uId == Id && t.TradingDate == date));
if (!(dateAvailable)) {
return Json(new {
status = false, msg = "This date already exists."
});
}
return Json(new {
status = true
});
}
JavaScript
$(document).ready(function() {
var message;
var isDateValid;
function CheckDate(para) {
var dateValid;
var mesg;
return $.ajax({
url: '#Url.Action("IsDateAvailable", "Trading")',
type: "GET",
data: para,
dataType: "json",
success: function(data) {
if (!(data.status)) {
message = data.msg;
} else {
isDateValid = true;
}
},
error: function(xhr, httpStatusMessage) {
alert(xhr + httpStatusMessage);
}
});
}
$("#datePicker").change(function() {
$("#alert").css({
'display': 'none'
});
if (Id == 0) {
$("#alert").attr('class', 'alert alert-danger');
$("#alert").text('Please select a User.');
$("#alert").show();
return false;
}
var date = $(this).val();
var para = {
date: date,
Id: Id
};
CheckDate(para);
if (isDateValid) {
$("#btnAdd").show();
} else {
$("#btnAdd").css({
'display': 'none'
});
$("#alert").attr('class', 'alert alert-danger');
$("#alert").text(message);
$("#alert").show();
}
});
});
You should turn to being asynchronous. change your code to match with these:
.
.
.
function CheckDate(para) {
return new Promise((resolve, reject) => {
return $.ajax({
url: '#Url.Action("IsDateAvailable", "Trading")',
type: "GET",
data: para,
dataType: "json",
success: function(data) {
if (!(data.status)) {
message = data.msg;
} else {
isDateValid = true;
}
resolve();
},
error: function(xhr, httpStatusMessage) {
alert(xhr + httpStatusMessage);
reject();
}
});
}
.
.
.
checkDate(para).then(res => {
if (isDateValid) {
$("#btnAdd").show();
} else {
$("#btnAdd").css({
'display': 'none'
});
$("#alert").attr('class', 'alert alert-danger');
$("#alert").text(message);
$("#alert").show();
}
}).catch(err => { /* do something */ });
You just need to set async: false inside your ajax request. You can also remove the word return from the CheckDate, because of it's redundant:
function CheckDate(para) {
var dateValid;
var mesg;
$.ajax({
url: '#Url.Action("IsDateAvailable", "Trading")',
async: false,
type: "GET",
data: para,
dataType: "json",
success: function(data) {
if (!(data.status)) {
message = data.msg;
} else {
isDateValid = true;
}
},
error: function(xhr, httpStatusMessage) {
alert(xhr + httpStatusMessage);
}
});
}

I tried to resolve it but couldn't find a proper solution.
Help me with this, I cannot understand the cause of this error.
This is mainly due to Rules of Origins (CORS), for some reason the javascript(browser) sees the request as not residing in the same server. And the reason for that, I believe, is because /home/u919084925/public_html/mod/basket.php is not seen as a valid url on the server, it should start with http://{hostname}/{path}.
It looks like your ajax url is totally wrong and the browser interpret that is cross origin ajax request. Please simply check in browser's address bar if your ajax provided urls are valid.
I am trying to validate a basic login form with username and password fields. I need to validate username and password from check.php ajax page. There is no problem in ajax request and response. I am getting proper response from ajax page. But Ajax success function is not working properly.
ajaxrequest.html
$(document).on('pagebeforeshow', '#login', function(){
$(document).on('click', '#submit', function() {
if($('#username').val().length > 0 && $('#password').val().length > 0){
$.ajax({
url : 'serverurl/check.php',
data: {action : 'login', formData : $('#check-user').serialize()},
type: 'post',
beforeSend: function() {
$.mobile.loading(true);
alert("beforesend");
},
complete: function() {
$.mobile.loading(false);
alert("complete");
},
success: function (result) {
console.log("Ajax response");
res = JSON.stringify(result);
if(res.status == "success"){
resultObject.formSubmitionResult = res.uname;
localStorage["login_details"] = window.JSON.stringify(result);
$.mobile.changePage("#second");
}else{
$.mobile.changePage("#login");
alert("incorrect login");
}
},
error: function (request,error) {
alert('Network error has occurred please try again!');
}
});
} else {
alert('Fill all fields');
}
return false;
});
});
Here i have added my ajax page. This page only validates posted username and password. Finally it returns json object. What am i doing wrong?
serverurl/check.php
header("Access-Control-Allow-Origin: *");
header('Content-Type: application/json');
if(isset($_POST['formData']) && isset($_POST['action']) && $_POST['action'] == 'login'){
parse_str($_POST['formData'],$searchArray);
$uname = "arun";
$pwd = "welcome";
$resultArray = array();
if($uname == $searchArray['username'] && $pwd == $searchArray['password'])
{
$resultArray['uname'] = $searchArray['username'];
$resultArray['pwd'] = $searchArray['password'];
$resultArray['status'] = 'success';
}else{
$resultArray['status'] = 'failed';
}
echo json_encode($resultArray);
}
Your code should be
success: function (result) {
console.log("Ajax response");
//don't do this
//res = JSON.stringify(result);
if(result.status == "success"){
resultObject.formSubmitionResult = result.uname;
localStorage["login_details"] = window.JSON.stringify(result);
$.mobile.changePage("#second");
}else{
$.mobile.changePage("#login");
alert("incorrect login");
}
After JSON.stringify you are accessing like stringJson.status this will not work. it mast have "parsed" "json object" not stringify.
Don't need to convert your JSON to String.
$(document).on('pagebeforeshow', '#login', function(){
$(document).on('click', '#submit', function() {
if($('#username').val().length > 0 && $('#password').val().length > 0){
$.ajax({
url : 'serverurl/check.php',
data: {action : 'login', formData : $('#check-user').serialize()},
type: 'post',
beforeSend: function() {
$.mobile.loading(true);
alert("beforesend");
},
complete: function() {
$.mobile.loading(false);
alert("complete");
},
success: function (result) {
console.log("Ajax response");
//Don't need to converting JSON to String
//res = JSON.stringify(result);
//directly use result
if(result.status == "success"){
resultObject.formSubmitionResult = result.uname;
localStorage["login_details"] = window.JSON.stringify(result);
$.mobile.changePage("#second");
}else{
$.mobile.changePage("#login");
alert("incorrect login");
}
},
error: function (request,error) {
alert('Network error has occurred please try again!');
}
});
} else {
alert('Fill all fields');
}
return false;
});
});
Your AJAX call is perfect but datatype is not declared in ajax
Try with jSON OR JSONP. You will get success.
$.ajax({
url : 'serverurl/check.php',
type: 'post',
dataType: "json", OR "jsonp",
async: false,
data: {action : 'login', formData : $('#check-user').serialize()},
beforeSend: function() {
$.mobile.loading(true);
alert("beforesend");
},
complete: function() {
$.mobile.loading(false);
alert("complete");
},
success: function (result) {
console.log("Ajax response");
alert(JSON.stringify(result)); // Check response in alert then parse according to that
res = JSON.stringify(result);
if(res.status == "success"){
resultObject.formSubmitionResult = res.uname;
localStorage["login_details"] = window.JSON.stringify(result);
$.mobile.changePage("#second");
}else{
$.mobile.changePage("#login");
alert("incorrect login");
}
},
error: function (request,error) {
alert('Network error has occurred please try again!');
}
});
Under some circumstances your server might not return the response correctly. Have you tried to handle the actual response code (e.g. if your server returns 200) like this:
$.ajax({
url : 'serverurl/check.php',
data: {action : 'login', formData : $('#check-user').serialize()},
type: 'post',
....
statusCode: {
200: function (response) {
// do your stuff here
}
}
});
