This question has been asked a couple of time here, but I haven't seen any of the responses work for me.
I have this piece of code built with cakePHP which successfully returns the data in JSON format, but I haven't been able to insert this JSON data into HTML div using Javascript.
$('.book-click').click(function (e) {
e.preventDefault();
var getHotel = $(this).attr('hotel-id');
$.ajax({
type: "POST",
url: "<?php echo $this->Html->URL(array('action' => 'postBook')); ?>",
data: {
hotel: getHotel
},
cache: false,
dataTye: "json",
success: function (JSONObject) {
var myData = "";
for (var key in JSONObject) {
if (JSONObject.hasOwnProperty(key)) {
myData += JSONObject[key];
}
}
/*console.log(myData);*/
alert(myData[key]["hotelname"]); //Giving undifined in alert
}
});
});
And this is the JSON data I get when I log the data on browser console:
[
{
"id": "11",
"hotelname": "Sheraton hotel",
"hoteladdress": "Abule Ikeja",
"state": "Lagos State",
"lga": "Ikeja",
"hotelphone": "65645545454",
"hotelwebsite": "",
"adminphone": "6565656565",
"adminemail": "mail@hotel.com",
"hotelemail": "",
"facilities": ",,",
"roomscategory": "Diplomatic",
"standardrate": "150000",
"leanrate": "",
"aboutHotel": "",
"requestStatus": "0",
"createdOn": "1424360902",
"updatedOn": "1424360902"
}
]
How do I successfully, get this JSON data into HTML. Something like this:
$('#myDiv').html(myData[key]["hotelname"]);
I tried this, but it's just giving me Undefined
.
Any help is appreciated.
Use $.each()
to iterate:
success: function (JSONObject) {
$.each(JSONObject, function(k,item){
$('#myDiv').html(item.hotelname);
});
}
var json = [ { "id": "11", "hotelname": "Sheraton hotel", "hoteladdress": "Abule Ikeja", "state": "Lagos State", "lga": "Ikeja", "hotelphone": "65645545454", "hotelwebsite": "", "adminphone": "6565656565", "adminemail": "mail@hotel.com", "hotelemail": "", "facilities": ",,", "roomscategory": "Diplomatic", "standardrate": "150000", "leanrate": "", "aboutHotel": "", "requestStatus": "0", "createdOn": "1424360902", "updatedOn": "1424360902" } ] $.each(json, function(i, item){ $('body').append(item.hotelname); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
As per your error, it seems that you either you don't have a valid json or that is a json string. So before loopin you have to parse it:
success: function (JSONObject) {
var data = $.parseJSON(JSONObject); // parse it
$.each(data, function(k,item){
$('#myDiv').html(item.hotelname);
});
}
var myData = "";
for (var key in JSONObject) {
if (JSONObject.hasOwnProperty(key)) {
myData += JSONObject[key];
}
}
myData
here is simply just a string
. Hence the call myData[key]["hotelname"]
will return undefined, because you're trying to access something that does not exist.
Why not just use the result as-is from the Ajax call?
