can you guys help me, I am not really a JS dev so i am polling my hair out with this one.
i'm working with Ajax to display data from a json file...but it doesn't work, i put console.log almost everywhere to see result but it won't work, here's my code:
encode data:
// Inclusion du ficher de fonction permettant de démarrage du contexte de l'applicaiton
Include $_SERVER["DOCUMENT_ROOT"].DIRECTORY_SEPARATOR."Includes".DIRECTORY_SEPARATOR."Functions".DIRECTORY_SEPARATOR."functions.php";
// Initialisation des variables
$action = '';
$pValue = '';
$pType = '';
$pRegion = '';
$currenthyperviseur = new hyperviseur();
$currentregion = new region();
// Récupération de l'action passée au webservice
if(isset($_REQUEST['action']) && $_REQUEST['action']!= "") {$action = $_REQUEST['action']; }
if(isset($_REQUEST['pValue']) && $_REQUEST['pValue']!= "") {$pValue = base64_decode($_REQUEST['pValue']); }
if(isset($_REQUEST['pType']) && $_REQUEST['pType']!= "") {$pType = $_REQUEST['pType']; }
if(isset($_REQUEST['pRegion']) && $_REQUEST['pRegion']!= "") {$pRegion = $_REQUEST['pRegion']; }
// Gestion de l'ensemble des cases du web service
switch($action)
{
//
// Permet la récupération de données dans l'Hyperviseur (GET)
//
case 'H_getAlmBacPFull' : echo json_encode($currenthyperviseur->getListAlarmeBac(1)); break;
case 'H_getAlmBacTFull' : echo json_encode($currenthyperviseur->getListAlarmeBac(2)); break;
case 'H_getGrpBacTFull' : echo json_encode($currenthyperviseur->getListAlarmeQualifBac()); break;
case 'H_getAlmDetails' : echo json_encode($currenthyperviseur->getAlarmeDetails($pValue)); break;
case 'H_getGrpDetails' : echo json_encode($currenthyperviseur->getGroupeDetails($pValue)); break;
//
// Permet la MAJ de données dans l'Hyperviseur (SET)
//
case 'H_setCheckAlm' : echo $currenthyperviseur->setAlarmeCheckAction($pValue); break;
case 'H_setGroupAlm' : echo $currenthyperviseur->setGroupAlarme($pValue); break;
case 'H_setAlmIdGrp' : echo $currenthyperviseur->setAlarmeIdGrp($pValue); break;
//
// Permet la récupération de données pour le module 'HyperViseur MoreDetails' (GET)
//
case 'HVMD_getContentBloc' : echo json_encode($currenthyperviseur->getContentBloc($pType, $pValue)); break;
//
// Permet la récupération de données pour le module 'Region' (GET)
//
case 'R_getListContentBloc' : echo json_encode($currentregion->getListContentBloc($pType)); break;
case 'R_getContentBloc' : echo json_encode($currentregion->getContentBloc($pType, $pRegion)); break;
//
// Permet la récupération de données pour le module la map des régions
//
case 'dashMap_getSite' : echo json_encode($dashMap_getSite($pRegion); break;
}
function dashMap_getSite($pRegion) to get data:
$dataArray = array();
if($pRegion == 'all')
{
$dataLine = array();
$dataLine['codeSite'] = "01014";
$dataLine['latitude'] = '46.2625';
$dataLine['longitude'] = '5.6380';
$dataLine['nom'] = 'Oyonnax 2';
$dataLine['nbAlm'] = 10;
$dataLine['critilevel'] = 2;
array_push($dataArray, $dataLine);
$dataLine = array();
$dataLine['codeSite'] = "04025";
$dataLine['latitude'] = '44.4242';
$dataLine['longitude'] = '6.7533';
$dataLine['nom'] = 'Barcelonette 3 Est TDF';
$dataLine['nbAlm'] = 0;
$dataLine['critilevel'] = 1;
array_push($dataArray, $dataLine);
}
return $dataLine;
And this second function getArrayOfSiteAjax() to display it with ajax
console.log(gWsProviderUrl);
$.ajax({
url: gWsProviderUrl + '?action=dashMap_getSite&pRegion=all',
type: 'POST',
dataType: 'json',
success:function(data){
console.log('arrayOfSite');
arrayOfSite = data;
$.each(arrayOfSite, function(currentIdx, currentValue){
console.log('codeSite => ' + currentValue.codeSite );
console.log('latitude => ' + currentValue.latitude );
console.log('longitude => ' + currentValue.longitude );
console.log('nom => ' + currentValue.nom );
console.log('nbAlm => ' + currentValue.nbAlm );
console.log('critilevel => ' + currentValue.critilevel);
});
console.log('heyy');
}
});
Thank you !
case 'dashMap_getSite' : echo json_encode($dashMap_getSite($pRegion); break;
That's a syntax error and should probably be
case 'dashMap_getSite' : echo json_encode(dashMap_getSite($pRegion)); break;
Because there was an error, the success callback didn't get called, an you don't get a message.
To display the data, you could do something like this:
// ...
success: function (data) {
var container = $('#container'); // the element in which you want to display the data
// loop over each item in the array
$.each(data, function (index, element) {
var outer = $('<div />');
// element is an object, loop over its properties
$.each(element, function (key, value) {
var inner = $('<div />');
inner.text(key + ': ' + value);
outer.append(inner);
})
container.append(outer);
});
}
// ...

Imagine I have a CRUD table with a button to delete a register.
What I'm trying to do?
Basically, I want that, the parameters that there are in the function Delete() (3 variables), they arrive to me to PHP again by means of POST method so that with these data I can make the query and to delete the registry in the Database.
The information I want to pass on is as follows:
$data->id // Value example: 1
$tableName // Value example: users_test
$field // Value example: id
My button:
<button onclick='Delete($data->id, $tableName, $field)'>Delete</button>
My Delete JS function (basically I create a POST request sending an action to my PHP.
function Delete(id, tableName, field){
$.post("<?=SITE_URL_ADMIN?>/alexcrudgenerator/crud/res/", {
action: "deleteRegistro"
}, function (data, status) {
if (confirm("¿Estás seguro que deseas borrar el registro?") == true) {
if (status === 'error') {
console.log("Not deleted"); // For debugging purpose
} else if (status === 'success') {
console.log("Deleted successfully");
}
}
else {
return false;
}
});
}
My PHP:
switch($_POST['action']){
case 'deleteRegistro':
$id = $_POST['id']; // Quiero obtener estas variables que he enviado desde la función Delete();
$tableName = $_POST['tableName']; // Quiero obtener estas variables que he enviado desde la función Delete();
$field = $_POST['field']; // Quiero obtener estas variables que he enviado desde la función Delete();
break;
}
This if my full code if you need it:
<?php
use GuzzleHttp\json_decode;
include_once(DIR_PLUGINS.'/alexcrudgenerator/main.php');
$test = new GenerateCrud($_POST['tableName'], $_POST['id'], $_POST['tableFields']);
if ($_GET['action']){
print_a($_GET['action']);
}
switch($_POST['action']){
case 'datosTabla': // OK.
//print_r($_POST['action']);
$res = json_decode($_POST['datos']);
echo json_encode($res, JSON_UNESCAPED_UNICODE);
break;
case 'deleteRegistro':
$id = $_POST['id']; // Quiero obtener estas variables que he enviado desde la función Delete();
$tableName = $_POST['tableName']; // Quiero obtener estas variables que he enviado desde la función Delete();
$field = $_POST['field']; // Quiero obtener estas variables que he enviado desde la función Delete();
break;
case 'showtable': // OK.
$res = getEntireTable($_POST['tableName'], $_POST['id'], $_POST['tableFields']);
$tableName = $_POST['tableName'];
$field = json_decode($_POST['tableFields'],1)[0];
//print_r($tableName);
//print_r('<br>');
//print_r($campo);
foreach ($res as $data){
$data->acción = "<div class='text-center'><div class='btn-group'><button id='modificar_$data->id' class='btn btn-primary btn-sm btnEditar' value='edit'><i class='material-icons'>edit</i></button><button onclick='Delete($data->id, $campo)' class='btn btn-danger btn-sm btnBorrar'><i class='material-icons' value='delete'>delete</i></button></div></div>";
$resultados['data'][] = $data;
}
$resultados = json_encode($resultados); // 7 PROPIEDADES
foreach(json_decode($_POST['tableFields']) as $columnsDB){
$fields[] = array('data'=>$columnsDB);
}
$fields[]['data'] = 'acción';
$fields = json_encode($fields);

May be you should try something, like this:
function Delete(id, tableName, field){
$.post(
"<?=SITE_URL_ADMIN?>/alexcrudgenerator/crud/res/",
{
action: "deleteRegistro"
id: id,
tableName: tableName,
field: field
},
function (success) {....}
)};
Have you forgotten id, tableName and field?
There is also the newer fetch.then
function ajaxpost (divid,var1,var2,var3) {
var pcache = (Math.floor(Math.random() * 100000000) + 1); // this is important to avoid browser cache
var postix = [];
postix["divid"] = encodeURIComponent(divid);
postix["var1"] = encodeURIComponent(var1);
postix["var2"] = encodeURIComponent(var2);
postix["var3"] = encodeURIComponent(var3);
postix["cookies"] = decodeURIComponent(document.cookie); // if you need to send cookies
postix["windowwidth"] = encodeURIComponent($(window).width()); // optional but cool if you need to retrive more that just text....
postix["windowheight"] = encodeURIComponent($(window).height());
// this code will retrieve ALL localStorage and sessionStorage to send to php if you need
for (var i = 0; i < localStorage.length; i++){ postix[localStorage.key(i)] = localStorage.getItem(localStorage.key(i)); }
for (var i = 0; i < sessionStorage.length; i++){ postix[sessionStorage.key(i)] = sessionStorage.getItem(sessionStorage.key(i)); }
fetch("/path_to_php.php?pcache="+pcache, {
method: "POST",
body: JSON.stringify(Object.assign({}, postix)),
headers: {"Content-type": "application/json; charset=UTF-8"}
}).then(function (response) { return response.text(); })
.then(function (html) { $("#"+divid).html(html); })
.catch( err => console.log() );
}
I'm in traineeship in a company and I need to used the program of another trainee who programmed it in 2012. So I have done some update but I have a some problems :
When I press a button, I have a JS that make a xhr.get to recover a JSON. But I have this message on my firefox console :

The JS code is trying to load the absolute path /query/, but your Django patterns are setup to respond to ^home/query. Try using /home/query as your xhr URL.
For over a week I can not solve a problem with ajax . I have a form where the customer chooses the product to buy , the amount you are going to buy , and to what extent ( 1kg, 5kg, etc ) . Everything works properly, when you choose the product, the other two fields with the corresponding quantities and units will auto . When sending the form, tells me the following error:
The controller must return a response (null given). Did you forget to add a return statement somewhere in your controller?
I'll put all code , but actually the problem should be in the driver. To that reading is not so difficult to do , I will be commenting on each step.
1°: First, sending the form to the view. (obviously , first passes through the routing, but do not go if)
TablasController.php
public function pedidoAction()
{
$em = $this->getDoctrine()->getManager();
$prodped= new ProdPedido();//creo la entidad de los productos
$form = $this->createForm(new ProdPedidoType(), $prodped);
$nombres = $em->getRepository('ProyectoAdminBundle:Catalogo')->findByArticulo();
return $this->render('AtajoBundle:General:pedido.html.twig', array('form' => $form->createView(), 'nombres' => $nombres));
}
2°: I reduced a little code so that not so long . Here , I present the form, and make the corresponding javascript that handles dynamically add fields , and that I mentioned above, the auto-complete fields. Although this does not go much to the case , since the problem would be in the controller.
pedido.html.twig
{% block content %}

3°: This is where it is assumed that this error. For me it is the way to return the information to the ajax , but not really , because it seems like it's okay . Return information through a view, everything works fine , the fields will auto . But sending the form , I get this error.

a response object requires data in an associative array. Your code gives an entity object. You have to convert that entity to an array.
If you would like to convert all the entity data into an array then you could use JMSSerializer. See also this other stackoverflow topic
Try modifying the code as given below. It includes changes to your controller actions as well as the ajax call in the
template.
public function recuperarMedidasyUnidadesAction(){
$id = $_POST['id'];
$em = $this->getDoctrine()->getManager();
// busco las diferentes unidades que existen (1kg, 5kg, 10kg, etc)

//modified code
$status = 'error';

I get an "Uncaught SyntaxError: Unexpected string " when I try to parse my xhr.responseText, I've looked for answers but cannot find any that can relate to my problem directly. I seem to understand that my xhr.responseText may be JSONP because it is manipulated byt the callback but that doesn't help me, how can I just have a JSON? I want to be able to use my JSON in my Javascript with the Google Maps API. I'm really confused and just trying to make this work, thanks for reading and possibly helping.
Here's my PHP script.

} catch (PDOException $e) {
exit("Erreur lors de la connexion à la BD :<br />\n" . $e->getMessage());

strReperes = strReperes.replace(/}{/g, '}~{');
strReperes = strReperes.split('~');
var coordonnees;
var id;
reperes = '[';
for (var i = 0; i < strReperes.length; i++){
var numberPattern = /\d+/g;
id = strReperes[i].split(',')[0];
id = id.match( numberPattern );
coordonnees = strReperes[i].split(',')[1] + ',' + strReperes[i].split(',')[2];
coordonnees = coordonnees.replace(/"/g, '');
coordonnees = coordonnees.replace('coordinates: ', '');
coordonnees = coordonnees.split(',');
reperes += '{"long": ' + coordonnees[0] + ', "lat": ' + coordonnees[1] + ', "id": ' + id + '}';
if (i != strReperes.length - 1) {
reperes += ', ';
}
}
reperes += ']';
reperes = JSON.parse(reperes);
} catch (e) {
alert('ERREUR: La réponse AJAX n\'est pas une expression JSON valide.');
return;

}
As you can see in creeReperes() i need to do some unorthodox manipulation with the xrhresponsetext instead of using a JSON.
Oh and sorry if some of the code is in french.

Only works on Chrome/Firefox and Not on IE.
I don't know why, I googled about JQuery and IE errors, tried the 'fixes' and they still do not work.
Thank you in advance.
UPDATE
It now works.
The problem with IE is that the XML It was receiving was bad because IE doesn't allow áéíóú letters (commonly used in spanish) instead displaying a square character therfor it could't process the XML.
