I have a getJSON call that is called back correctly, but the data variable is null. The python code posted below is executed by the getJSON call to the demandURL. Any ideas?
javascript:
var demandURL = "/demand/washington/";
$.getJSON(demandURL, function(data) {
console.log(data);
});
python:
data = {"demand_count":"one"}
json = simplejson.dumps(data)
return HttpResponse(json, mimetype="application/json")
Switch out your getJSON with an ajax call so you can have a look at the error message. Try something like this:
$.ajax({
url: url,
dataType: 'json',
data: data,
success: function(data) {
console.log(data);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
}
});

i'm trying to get only the returned URL from ajax request
like this
$.ajax({
type: "GET",
dataType : "jsonp",
async: false,
url: $('#FaceBookProfileLink').attr('href'),
success: function(response) {
console.log(response);
},
error: function (jqXHR, textStatus, errorThrown) {
console.log(jqXHR);
console.log(textStatus);
console.log(errorThrown);
}
});
but i can't.
the returned URL showing in the console as js file but i can't get it
please any help and many thanks in advance.
As you are using 'GET' method, retrieve them with $_GET[], ie:
echo $_GET['code']
I want to get base64 data and i have a url which will be give me the file.
I have tried the below mentioned way to get base64 data from URL
I have made a ajax call to the the given URL
$.ajax({
type: "GET",
url: DownloadUrl,
success: function (data, textStatus, jqXHR){
if (data){
}
},
error: function (xhr, statusText, errorThrown) {
console.log(statusText);
}
});
In the success event, i am getting some decoded data, I have encoded that using "window.btoa". But now my file is getting corrupted after this way.
Is this the right way to get base64 data?
Any other Way to get this data?
Did you try to call encodeURIComponent on the returned data?
$.ajax({
type: "GET",
url: DownloadUrl,
success: function (data, textStatus, jqXHR) {
if (data) {
data = btoa(encodeURIComponent(data));
}
},
error: function (xhr, statusText, errorThrown) {
console.log(statusText);
}
});
I'm trying to test the successful submission of data from javascript to a php file by having that php file return the results of the javascript post back to javascript. I'm getting a successful response in the ajax post, but the data is an empty string. How do I find out what data was posted? Here's my code:
JAVASCRIPT:
var benefitsArray = ["someData","someOtherData"];
$('#drop-submit').on('click',function(){
if (benefitsArray.length > 0){
var formData = { "benefits" : benefitsArray };
debugger;
$.ajax({
url : "dd-receiver.php",
type: "POST",
data : formData,
success: function(data, textStatus, jqXHR)
{
console.log(data); //result is "";
debugger;
//data - response from server
},
error: function (jqXHR, textStatus, errorThrown)
{
console.log('failure');
}
});
}
});
PHP:
<?php
echo $_POST["benefits"]
?>
UPDATE:
I got a response by, in the php code, doing:
echo json_encode($_POST['benefits']);
but the problem is that in the javascript, if I log the data, the result is
"["someData","someOtherData"]" (a string)
and not
["someData","someOtherData"] (an array)
how do I get it to return an array and not a string?
You're not parsing the JSON being sent to you.
You can make jQuery do this for you by adding dataType: 'JSON' to your $.ajax options...
$.ajax({
dataType: 'JSON',
url : "dd-receiver.php",
type: "POST",
data : formData,
success: function(data, textStatus, jqXHR) ...
Or manually with JSON.parse:
success: function(data, textStatus, jqXHR) {
benefits = JSON.parse(data);
...
}
How to access this json data in JavaScript.
when I alert it the result is undefined
Here is jQuery code
$.ajax({
type: "POST",
url: "frmMktHelpGridd.php",
data: {
labNo: secondElement
},
dataType: "json",
beforeSend: function () {
// Do something before sending request to server
},
error: function (jqXHR, textStatus, errorThrown) {
alert('error has occured');
alert(errorThrown);
},
success: function (data) {
//Here is the problem
alert(data[0]['Result']);
}
});
This is PHP code
$data=array($no);
for($i=0;($i<$no && ($row=mysql_fetch_array($result)));$i++)
{
$data[$i]=array();
$data[$i]['Result'] = $row['Result'];
$data[$i]['TestCode'] = $row['TestCode'];
$data[$i]['TestStatus'] = $row['TestStatus'];
$data[$i]['SrNo'] = $row['SrNo'];
}
$data1=json_encode($data);
echo $data1;
exit;
I have tested the PHP file independently,
The json data is output as follows:
[{"Result":"1","TestCode":"22","TestStatus":"0","SrNo":"1"},{"Result":"1","TestCode":"23","TestStatus":"1","SrNo":"2"}]
$.ajax({
type: "POST",
url: "frmMktHelpGridd.php",
data: {
labNo: secondElement
},
dataType: "json",
beforeSend: function () {
// Do something before sending request to server
},
error: function (jqXHR, textStatus, errorThrown) {
alert('error has occured');
alert(errorThrown);
},
success: function (data) {
//Added parse json
var data = jQuery.parseJSON(data)
alert(data[0]['Result']);
}
});
You can access to your data by doing
data[0].Result
It's an Object, not an array.
so data[0]['Result'] it's not the proper way
EDIT:
Since you have more objects, you have to do a loop this way:
$.each(data, function(key, val){
console.log(val.Result);
console.log(val.TestCode);
//...
});
When you see something like
{
"foo":"bar",
...
}
you can access to it the same way as above:
name_of_the_object.foo
that will have the value "bar"
Try to add parse JSON. I have added. Now it may be work.
$.ajax({
type: "POST",
url: "frmMktHelpGridd.php",
data: {
labNo: secondElement
},
dataType: "json",
beforeSend: function () {
// Do something before sending request to server
},
error: function (jqXHR, textStatus, errorThrown) {
alert('error has occured');
alert(errorThrown);
},
success: function (data) {
//Added parse json
var data = $.parseJSON(data)
alert(data[0]['Result']);
}
});
I use Backbone.js and jQuery 1.7 in my application and I have some problems in building collection. In collection I have the method, which should return some object. I do "return" in $.ajax(...) success() function.
In this case i receive "undefined" instead of expected object. I understand, that the problem is in the "return" - it make success() function return some value. But I need getDomainZones() method do a return. How can I do it?
window.DmnList = Backbone.Collection.extend({
model: DmnItem,
localStorage: new Store("hosting.WhoIs"),
destroyAll: function (options) {
while (this.models.length > 0) {
this.models[0].destroy(options);
}
},
getDomainZones: function(){
$.ajax({
url: 'http://hosting/rest/getDomains',
type: 'GET',
dataType: 'json',
cache: 'false',
timeout: 5000,
success: function(data) {
console.log(data);
return data;//problem here
},
error: function(jqXHR, textStatus, errorThrown) {
console.log("Error[getDomainZones]: " + textStatus);
console.log(jqXHR);
},
});
}
});
"Where I should place return statement"
Nowhere. You can't return the result of an asynchronous AJAX request.
Any code that relies on the data, must be called inside the success callback.
One possibility is to have your getDomainZones method receive a function that will be called when the response is received.
getDomainZones: function( callback ){
$.ajax({
url: 'http://hosting/rest/getDomains',
type: 'GET',
dataType: 'json',
cache: 'false',
timeout: 5000,
// success: callback, // alternative if there's no other work to do.
success: function(data) {
console.log(data);
callback( data ); // invoke the function received
},
error: function(jqXHR, textStatus, errorThrown) {
console.log("Error[getDomainZones]: " + textStatus);
console.log(jqXHR);
},
});
}
So then you'd pass a function to getDomainZones, and when the response is received, getDomainZones will invoke the function you passed, passing it the data.
getDomainZones( function( d ) {
// do something with the data
console.log( d );
});
