I've successfully inserted the data from my sign-up form i just want to inform the user that they successfully registered on the alert box
Maybe it's not succeeding. Have you tried throwing in an error handler to see if it's failing?
$.ajax({
type: "POST",
url: url,
data: data,
success: function(response){
alert("success"); --> this is the one
},
error: function (XHR, status, error){
console.log('error', error);
}
});

what is the opposite of -> success: function(data)
$.ajax({
type: "POST",
cache: false,
url: "/p.php",
data: info,
success: function(data){
I want to check if it is not success instead of if it is success...
You catch success situation with success function and there is also error function. Please see the documentation http://api.jquery.com/jquery.ajax/
And please see this for detailed xhr catch mechanizm
$.ajax({
type: "POST",
cache: false,
url: "/p.php",
data: info,
success: function(data){
//do something
},
error: function(jqXHR, textStatus, errorThrown){
console.log(errorThrown);
}
I am trying to fetch the message table and append the response on the previous fetched results...
here are 2 approaches I have tried, but all failed
1st: recursive fetch
function fetch(){
$.ajax({
url: url,
type: "post",
data:data,
timeout: 3000,
success: function(data){
$(selector).append(data);
setTimeout(function(){fetch()},3000);
}
})
}
2nd: setInterval()
setInterval(function(){fetch()},3000);
function fetch(){
$.ajax({
url: url,
type: "post",
data:data,
timeout: 3000,
success: function(data){
$(selector).append(data);
}
})
}
after few successful ajax call, the browser went frozen and console shows "net::ERR_EMPTY_RESPONSE " OR "ERR_CONNECTION_TIMED_OUT"
please advise
thank you
You may this this if you want to make a recursive call after success or failure
function fetch(url, selector){
$.ajax({
url:url,
type:"post",
data:data,
timeout:3000,
success:function(data){
$(selector).append(data);
fetch();
},
error:function(data){
fetch();
}
});
}
I'm trying to use an ajax call to bring back data from a web api. I wrote 2 similar functions and neither work. I can see the data come back through Fiddler, but it won't go to the success call, for both of the functions below. What am I doing wrong? The data comes back in both functions in Fiddler, it just doesn't go to success.
Here is attempt 1:
function PopulateDivisions()
{
$.support.cors=true;
$.ajax({
type:'GET',
url:'http://IP/Service/api/DivisionSearch/GetAllDivisions',
data: {},
contentType: 'application/json; charset=utf-8',
dataType: 'jsonp',
success: function(data) {
alert(data);
$("#divisionSelect").append($('<option></option>').val("-99").html("Select One"));
$.each(data, function(i, item){
$("#divisionSelect").append($('<option></option>').val(item.Name).html(item.Name));
});
},
error: function(xhrequest, ErrorText, thrownError) {
alert("Original: " + thrownError + " : " + ErrorText);
}
});
}
Error: jQuery19102671239298189216_1382022403977 was not called : parser error
Here is the data Fiddler is showing comes back:
[{"Id":1,"Description":"Executive","Name":"Executive "},{"Id":2,"Description":"ASD","Name":"Administrative Services Division "},{"Id":3,"Description":"COM","Name":"Communications "},{"Id":4,"Description":"CP","Name":"Contracts and Procurement "},{"Id":5,"Description":"PMD","Name":"Program Management Division "},{"Id":6,"Description":"RED","Name":"Research and Evaluation Division "},{"Id":7,"Description":"IT","Name":"Information Technology "}]
Here is attempt #2:
function PopulateDivisions2()
{
$.support.cors=true;
$.ajax({
type:'GET',
url:'http://IP/Service/api/DivisionSearch/GetAllDivisionsJsonP',
data: {},
contentType: 'application/json; charset=utf-8',
dataType: 'jsonp',
jsonp: false,
jsonpCallback: "myJsonMethod",
success: function(data) {
//data = JSON.parse(data):
alert(data);
$("#divisionSelect").append($('<option></option>').val("-99").html("Select One"));
$.each(data, function(i, item){
$("#divisionSelect").append($('<option></option>').val(item.Name).html(item.Name));
});
},
error: function(xhrequest, ErrorText, thrownError) {
alert("PopulateDivisions2: " + thrownError + " : " + ErrorText);
}
});
}
Error: myJsonMethod was not called : parsererror
Here is the data Fiddler shows is coming back:
"myJsonMethod([{\"Id\":1,\"Description\":\"Executive\",\"Name\":\"Executive \"},{\"Id\":2,\"Description\":\"ASD\",\"Name\":\"Administrative Services Division \"},{\"Id\":3,\"Description\":\"COM\",\"Name\":\"Communications \"},{\"Id\":4,\"Description\":\"CP\",\"Name\":\"Contracts and Procurement \"},{\"Id\":5,\"Description\":\"PMD\",\"Name\":\"Program Management Division \"},{\"Id\":6,\"Description\":\"RED\",\"Name\":\"Research and Evaluation Division \"},{\"Id\":7,\"Description\":\"IT\",\"Name\":\"Information Technology \"}]);"
contentType: 'application/json; charset=utf-8' Tells your server that you are sending JSON data, but you don't have any data you are sending. Try leaving that setting out.
If you were to brows to your url in the browser do you get json back?
I'm not sure if this would matter, but I would remove the error setting because it says in the jQuery Ajax documentation that This handler is not called for cross-domain script and cross-domain JSONP requests.
I would try to run this with the least amount of configuration like this:
$.ajax({
url:'http://IP/Service/api/DivisionSearch/GetAllDivisions',
dataType: 'jsonp',
success: function(data) { console.log(data); }
});
See if this works and then build on top of it. Without jsfiddle it's hard to debug what's going on.
Here is a link that should be a good resource for you: Basic example of using .ajax() with JSONP?
function PopulateDivisions2(){
$.support.cors=true;
$.ajax({
type:'GET',
url:'http://IP/Service/api/DivisionSearch/GetAllDivisionsJsonP?callback=?',
data: {},
contentType: 'application/json; charset=utf-8',
dataType: 'jsonp',
jsonpCallback: "myJsonMethod" });
function myJsonMethod(data) {
//data = JSON.parse(data):
alert(data);$("#divisionSelect").append($('<option></option>').val("-99").html("Select One"));
$.each(data, function(i, item){
$("#divisionSelect").append($('<option></option>').val(item.Name).html(item.Name));
});
}}
Can you try the above code? I have removed the success callback and included callback in query string.
I am trying to use jsonp to access the data at:
https://github.com/users/jbranchaud/contributions_calendar_data
However, none of the solutions I have tried are resulting in either the callback or the success function getting invoked. When I use Chrome/Firefox inspection tools, I can look at the script and see that the response was 200 Ok and that the response text contains the data from the above URL. Nevertheless, neither the callback function nor the success function get called at any point. Any ideas about how to get this to work?
Here is my most recent attempt at getting this to run:
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
function parseResults(results) {
console.log('hello function callback.');
}
$.ajax({
url: 'https://github.com/users/jbranchaud/contributions_calendar_data',
type: 'post',
dataType: 'jsonp',
jsonp: true,
jsonpCallback: 'parseResults',
success: function(data, textStatus, jqXHR) {
console.log('success_function');
console.log(data);
},
error: function() {
console.log('error with jsonp request');
}
});
</script>
When I load the page, I see the 'error with jsonp request' in the console, so there is an error with the ajax request. Ideas of why this request isn't succeeding?
In the ajax request, try to set the attribute 'jsonp' to false (jsonp: false).
Basically, JQuery generate an automatic function callback name, like this : JQuery1223...34.
In your case, you ,already, explicitly set the jsonpCallback function name. so you have to put jsonp attribut to false.
your code should be like this :
$.ajax({
url: 'https://github.com/users/jbranchaud/contributions_calendar_data',
type: 'post',
dataType: 'jsonp',
jsonp: false,
jsonpCallback: 'parseResults',
success: function(data, textStatus, jqXHR) {
console.log('success_function');
console.log(data);
},
error: function() {
console.log('error with jsonp request');
}
});
I am trying to submit a form with the user's inserted data and get the html back from the page called (update.asp).
How do I get the html response and how do I write it to a div on the page? The response would be "success".
If my page throws a 500 or other type of error, how can I handle that?
$('input#btnUpdate').click( function() {
$.ajax({
url: 'update.asp',
type: 'post',
dataType: 'json',
data: $('form#myForm').serialize(),
success: function(data) {
// how do i catch the response? is this the right place?
},
error: function(data) {
// how do I catch the error code here?
}
});
The response from the server in both cases would be passed to the callback as the data variable in your example. Try using console.log(data) inside of your callbacks to see the result in your developer console.
$('input#btnUpdate').click( function() {
$.ajax({
url: 'update.asp',
type: 'post',
dataType: 'json',
data: $('#myForm').serialize(),
success: function(response) {
$("#yourDIV").html(response);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(thrownError); //output, 500
}
});
});
