I have the following code:
$(document).ready(function(){
$.ajax({
url: "svc/GetTweetsByUser.php",
type: "POST",
success: function(data) {
alert('success');
},
failure: function(){
alert('fail');
},
data: ({twitter_user : 'AdoboHobo'}),
dataType: "xml"
}
);//endof ajax
});
I'm kind of starting with web and ajax stuff... this worked perfectly by yesterday. I don't know what is happening now that neither success nor failure events are triggering. I'm shure that the request and response are perfectly working, I checked that with firebug.
Does anyone have any ideas for this? Thanks in advance.
use error: instead!
$.ajax({
url : "svc/GetTweetsByUser.php",
type : "POST",
success : function(data) {
alert('success');
},
error : function() {
alert('failure');
},
data : ( {
twitter_user : 'AdoboHobo'
}),
dataType : "xml"
});
Isn't it error instead of failure?

Currently, I open a url with
window.open("#iframeid", myurl);
However, ideally I want to check if the url exists before loading it.
I've changed my code to the following, but I cannot see where I'm going wrong.
Nothing appears to happen.
if I change .add to .src, I get an error.
Any help would be appreciated.
$.support.cors = true;
$.ajax({
url: myurl,
dataType: 'html',
success: function(data){
$("#iframeid").add(data);
},
error: function(data){
alert("didn't work");
}
});
You can execute code based on the statusCode:
$.ajax({
url: myurl,
dataType: 'html',
statusCode: {
200: function(){
//run your success code
},
404: function() {
alert( "page not found" );
}
}
});
$(function() {
var sineData;
$.ajax({
url : '../_php/loadFromDB.php',
type : 'POST',
data : 'getSines',
dataType : 'json',
success : function (result) {
console.log(result);
sineData=result;
},
error : function () {
alert("error");
}
})
});
Under Console->All->Response in firebug I get the below as expected:
[{"userID":"1","email":"user#mail.com","number":"800.256.6547","ext":"5788","startDay":"Sunday","endDay":"Thursday"}]
but when I look at sineData it is Undefined.
I want to be able to access these values like sineData[0].email
Where am I going wrong?
async: false, ended up fixing this for me but probably isnt the best solution for most aplications.
You are probably accessing sineData outside the ajax call. You are trying to access it before the asynchronous call is done. Try this:
function whenIsDone(result){
// Do whatever you want with the variable result
console.log(result[0].email);
}
$.ajax({
url : '../_php/loadFromDB.php',
type : 'POST',
data : 'getSines',
dataType : 'json',
success : whenIsDone,
error : function () {
alert("error");
}
})
Forgive me, I am a complete JSON newbie here. I'm trying to load a file of json information from an external file, and I'm not sure how I can tell if the information has loaded or not. Here's what I have so far:
$(document).ready(function(){
$.ajax({
dataType: 'json',
success: function(string) {
data = $.parseJSON(string);
console.log(data);
alert(data);
document.write(data);
},
url: 'http://www.site.com/mystuff.php'
});
});
I've tried putting all kinds of stuff to see if the info has loaded, as you can see, and nothing has. How do I know if I've even gotten anything? I would really appreciate any help!
As already pointed out, two things:
You don't need to parse the string when setting the datatype as JSON
Check if the request returned successfully at all
Which could look like this:
$(document).ready(function(){
$.ajax({
dataType: 'json',
success: function(json) {
console.log(data);
},
error : function(xhr, text) {
console.log('An error occurred', xhr, text);
},
url: 'http://www.site.com/mystuff.php'
});
});
When setting the datatype to JSON you also have to make sure that mystuff.php sets the Content-Type header to application/json:
<?php
header('Content-Type: application/json');
?>
No need to parse to json again.. you can directly use the object
Also add the error Function to keep a check if you are getting any error..
$(document).ready(function(){
$.ajax({
dataType: 'json',
beforeSend : function() {
console.log('Before Ajax Request Starts !!');
},
success: function(data) {
console.log(data);
alert(data);
document.write(data);
},
error : function(jqXHR, textStatus, errorThrown) {
alert("Error occurred: " + errorThrown);
},
beforeSend : function() {
console.log('Ajax Request Complete !!');
},
url: 'http://www.site.com/mystuff.php'
});
});
This makes sure you have feedback at every step..
I'm trying to do a jquery GET and i want to send a parameter.
here's my function:
$(function() {
var availableProductNames;
$.get("manageproducts.do?option=1", function(data){
availableProductNames = data.split(",");;
alert(availableProductNames);
$("#nameInput").autocomplete({
source: availableProductNames
});
});
});
This doesn't seem to work; i get a null in my servlet when i use request.getParameter("option");
If i type the link into the browser http://www.myite.com/manageproducts.do?option=1 it works perfectly.
I also tried:
$.get(
"manageproducts.do?",
{option: "1"},
function(data){}
which doesn't work either.
Can you please help me?
EDIT:
also tried
$.ajax({
type: "GET",
url: "manageproducts.do",
data: "option=1",
success: function(msg){
availableProductNames = msg.split(",");
alert(availableProductNames);
$("#nameInput").autocomplete({
source: availableProductNames
});
}
});
Still getting the same result.
If you say that it works with accessing directly manageproducts.do?option=1 in the browser then it should work with:
$.get('manageproducts.do', { option: '1' }, function(data) {
...
});
as it would send the same GET request.
Try this:
$.ajax({
type: 'get',
url: 'manageproducts.do',
data: 'option=1',
success: function(data) {
availableProductNames = data.split(",");
alert(availableProductNames);
}
});
Also You have a few errors in your sample code, not sure if that was causing the error or it was just a typo upon entering the question.
I got this working : -
$.get('api.php', 'client=mikescafe', function(data) {
...
});
It sends via get the string ?client=mikescafe
then collect this variable in api.php, and use it in your mysql statement.
This is what worked for me:
$.get({
method: 'GET',
url: 'api.php',
headers: {
'Content-Type': 'application/json',
},
// query parameters go under "data" as an Object
data: {
client: 'mikescafe'
}
});
will make a REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe
Good Luck.
I have a problem to refresh a bloc in my page.
Here is the request:
> $("#pwd_lost_link").click(function(){
alert('1');
$.ajax({
type : 'POST',
url: 'test.php',
dataType: 'json',
data :{"nom" : "akbar"},
success : function(data){
$("#main_bloc").append(data.msg);
alert('2');
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.responseText);
alert(errorThrown); }
}); })
and here is the php file
<?php
$return['nom'] = "ffrfrfrfr";
echo json_encode($return)
?>
It doesn't work. It give me a status error ( 0 ) and the page is automatically reloaded
Thanks
Michaël
Confusing question Michael, not sure what you mean by "the page is automatically reloaded" but you should do 2 things:
In the $.ajax() method, make sure your success called back is handling the data correctly. You are looking for data.msg but I don't see where .msg comes from.
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
data: {},
dataType: "json",
url: url,
success: function(data) {
// parse data object so you can see what's being returned ex. alert(data) or alert(data[0]) or alert(data.nom)
},
error: function (xhr, status, error) {
// XHR DOM reference: http://www.w3schools.com/dom/dom_http.asp
// check for errors ex. alert(xhr.statusText);
}
});
On the PHP side, you may want to debug there to see what is being received and what you are sending back.
Aside from that using an XHR viewer like Firebug or Chrome's built-in utility (CTRL+SHIFT+I) can be very helpful.
And on a final note, if pwd_lost_link is a link elment a id="pwd_lost_link" href="..." then you will have to stop the browser from following the link before you process the AJAX.
$("#pwd_lost_link").click(function(e) {
e.preventDefault();
alert('1');
$.ajax({
...
});
If you aren't seeing the '1' being alerted then that is definitely your first problem.
You're trying to access data.msg, but your PHP script is only creating data.nom. So data.msg doesn't exist. Try changing data.msg to data.nom and see if this does what you want.
