codeigniter ajax internet explorer - ajax

the following code works fine in FF, opera and chrome but fails in IE
function get_modelo(modelo) {
var selState = modelo;
alert (selState);
console.log(selState);
$.ajax({
url: "site/ajax_call", //The url where the server req would we made.
async: false,
type: "POST", //The type which you want to use: GET/POST
data: "state="+selState, //The variables which are going.
dataType: "HTML", //Return data type (what we expect).
//This is the function which will be called if ajax call is successful.
success: function(data) {
//data is the html of the page where the request is made.
$('#city').html(data);
}
})
}
Can't understand the problem.

console.log in IE doesn't work or causes problems.
See here:
What happened to console.log in IE8?
and here:
Testing for console.log statements in IE
and here:
http://paulirish.com/2009/log-a-lightweight-wrapper-for-consolelog/
or just google search IE console log
Everything else in your code looks like it would work fine.

Try this. Below will work in IE8 :P
$.ajax({
url: "site/ajax_call", //The url where the server req would we made.
async: false,
type: "POST", //The type which you want to use: GET/POST
data: { state: selState }, //The variables which are going.
dataType: "html", //Return data type (what we expect).
//This is the function which will be called if ajax call is successful.
success: function(data) {
var newDiv = $('<div></div>');
newDiv.html(data);
newDiv.appendTo("#city");
}
});

ColdFusion 2016 Ajax

I'm trying to figure out what is Adobe Coldfusion and how to work on this platform.
I'm stuck at simple issue.
On submit I send form with jQuery ajax to server.
But I got response: 500 (Element MY_VAR is undefined in FORM.)
What I'm doing wrong?
JS
$loginForm.on('submit', function(e) {
e.preventDefault();
var formData = new FormData(e.target);
$.ajax({
url: 'test.cfm',
method: 'POST',
cache: false,
processData: false,
data: formData,
error: function(err) {
console.log(err);
},
success: function(data, status) {
console.log(status);
console.log(data);
}
});
});
CF
<cfoutput>
<p>#form.myvar#</p>
</cfoutput>
500 indicates an internal server error.
Are you trying to display your form values after sending them?
Maybe try and use the cfdump tag. Very useful for debugging.
Try dumping the form scope and see what variables are actually in there.

How to show AJAX response message in alert?

I am sending username and password as request parameter to the server in AJAX and trying to show the response message. But not able to showing the response message.In fiddler it is showing the response message. But while on the browser screen it is not showing.PLEASE somebody help me out where i am wrong or need to change anything..
I have written like this-
$(document).ready(function () {
$("#btnCity").click(function () {
$.ajax({
type: "POST",
url: "http://test.xyz.com/login",
crossDomain: true,
contentType: "application/json; charset=utf-8",
data: { username: "abc", password: "1234" },
dataType: "JSONP",
jsonpCallback: 'jsonCallback',
async: false,
success: function (resdata) {
alert(resdata);
},
error: function (result, status, err) {
alert(result.responseText);
alert(status.responseText);
alert(err.Message);
}
});
});
});
TL;DR: I guess the problem is on the server side of your code (that we don't know yet).
At first: I don't know why it fails for you. I've taken your code and ran it against a public available JSONP API, that returns the current IP of your system and it worked.
Please try yourself using the URL: http://ip.jsontest.com/.
So most probably, the server doesn't return the right response to the JSONP request. Have a look at the network tab in developer tools. With your current code, the answer of the server should be something like:
jsonCallback({'someResponseKeys': 'someResponseValue'});
Note: The header should contain Content-Type:application/javascript!
BTW, even if this doesn't for now solve your problem - here are some tweaks, I'd like to advice to you:
Don't set async to false, at the documentation of jQuery.ajax() says:
Cross-domain requests and dataType: "jsonp" requests do not support synchronous
operation.
You don't need to set a jsonpCallback, because jQuery will generate and handle (using the success function a random one for you. Quote from the docs:
This value will be used instead of the random name automatically generated by jQuery. It is preferable to let jQuery generate a unique name as it'll make it easier to manage the requests and provide callbacks and error handling.
So here comes my code:
$(document).ready(function () {
$("#btnCity").click(function () {
$.ajax({
type: "POST",
url: "http://ip.jsontest.com/",
crossDomain: true,
data: { username: "abc", password: "1234" },
dataType: "JSONP",
success: function (resdata) {
console.log("success", resdata);
},
error: function (result, status, err) {
console.log("error", result.responseText);
console.log("error", status.responseText);
console.log("error", err.Message);
}
});
});
});
A working example can be found here.
Another solution, like Yonatan Ayalon suggested, can be done with a predefined function and then setting the jsonpCallback explicitly to the function that should be called.
if you see the response in Fiddler, it seems that the issue is in the callback function.
you are doing a jsonP call - which means that you need a callback function to "read" the response data.
Do you have a local function that calls "jsonCallback"?
this is a simple jsonP request, which initiates the function "gotBack()" with the response data:
function gotBack(data) {
console.log(data);
}
$.ajax({
url: 'http://test.xyz.com/login' + '?callback=?',
type: "POST",
data: formData,
dataType: "jsonp",
jsonpCallback: "gotBack"
});
You can try with the following methods and close every instance of chrome browser in task manager, then open browser in web security disable mode by the command "chrome.exe --disable-web-security"
success: function (resdata) {
alert(resdata);
alert(JSON.stringify(resdata));
},
And the better option to debug the code using "debugger;"
success: function (resdata) {
debugger;
alert(resdata);
alert(JSON.stringify(resdata));
},

Cannot get Facebook friends array on IE, but working on other browsers

This function is working on Chrome and Firefox but not on IE9, where errorHandler is logging this error message:
ERROR: getFriendsArray {"readyState":0,"status":0,"statusText":"No Transport"}
getUserAccessToken() is returning the right value. Any ideas what could it be, that only affects IE?
EDIT: seems that https://graph.facebook.com/me/friends directly on IE browser returns HTTP 400 error.
function getFriendsArray() {
var friendsArray = [];
$.ajax({
url: 'https://graph.facebook.com/me/friends',
data: {
access_token: getUserAccessToken(),
fields: 'name,picture,gender'
},
dataType: 'json',
cache: true,
async: false,
success: function(response) {
var data = '';
$.each(response.data, function(indice, item) {
friendsArray.push(item);
});
},
error: function(err) {
errorHandler('getFriendsArray', JSON.stringify(err));
}
});
return friendsArray.sort(sortByName);
}
$.ajax only supports using XMLHttpRequest or XDomainRequest (IE), the latter only supporting a few scenarios, and requiring that your page is SSL if the requested resource is SSL.
Instead, use FB.api, which handles this and much more, ensuring that the call makes it through, either by using JSONP, XHR, XDomainRequest, or Flash.

How do I use data passed back in the response from ajax jQuery?

I am trying to use the response from a jQuery ajax request to set the innerHTML of a div with a certain id. This is the code I am using:
$(".show_comments").click(function(){
var articleName = $(this).closest("article").find(".articlename").attr('id')
$.ajax({
url: "commentView.php",
data: { 'articleName': articleName },
cache: false,
dataType: "html", // so that it will auto parse it as html
success: function(response){
$(this).closest("article").find(".comments").html(response);
}
});
however it doesn't seem to be doing anything at all, I've tried googling around, but everything I can find says to do it the way I am doing it... I have tested in Firebug and the ajax request is giving me the exact response I want it too... But I just cant access this to set the innerHTML of the div to the response!
In your ajax success handler there is another scope and this points to not what you think. So change your code to:
var articleName = $(this).closest("article").find(".articlename").attr('id'),
that = this;
$.ajax({
url: "commentView.php",
data: { 'articleName': articleName },
cache: false,
dataType: "html", // so that it will auto parse it as html
success: function(response){
$(that).closest("article").find(".comments").html(response);
}
});
What I've changed: I added that variable that points to this instance and use it in the success handler instead.
How would you debug it yourself: if you tried to output console.log(this) and console.log($(this).closest("article").find(".comments")); you would see that it returns a wrong object (in first case) and nothing in second.

Chrome jquery ajax callback on success not firing

As far as I know, $.ajax has always worked pretty smoothly in every browser until now.
I have a pretty simple function, called when a couple of actions from the user occur.
In Firefox, everything runs smoothly. But in Chrome, while the $.ajax request is launched, the callback on success doesn't fire.
Here's the actual snippet:
var form = $("#templateCreator"),
formType = form.attr("method"),
formData = form.serialize(),
action = form.attr('action');
$.ajax({
type: formType,
url: action,
data: formData,
success: function(){
console.log('Can\'t see me in Chrome, but ok in firefox !')
// Handle all form submit events to form validator first
validator(form, targetInput);
}
});
What's puzzling is nothing seems wrong, data is serialized, and sent properly. Does anyone know what I missed?
Start by adding an error and complete method as #Jasper suggested.
$.ajax({
type: formType,
url: action,
data: formData,
success: function(){
console.log('Can\'t see me in Chrome, but ok in firefox !')
// Handle all form submit events to form validator first
validator(form, targetInput);
},
error: function() {
console.log($.makeArray(arguments));
},
complete: function() {
console.log($.makeArray(arguments));
}
});
Then you can:
open Chrome debugger (F12), go to the scripts tag, and put a breakpoint inside success/complete/error; check out the stack trace and values for an epiphany ;)
have a look at the console logs
For great joy, take off every Zig!
I had this issue, and set async: false. This works for me in Chrome. Looks like Chrome has an issue with async: true.
restget = function(url, cb){
$.ajax({
url: url,
dataType: 'json',
crossDomain: true,
async: false,
success: cb
});
Try this .....
data: formData,
async: false,
Chrome has some issues with async calls.
I had a similar problem while trying to get a json array. I had to add dataType: 'json' to my ajax so that non-Firefox browsers know what my data type is. For instance:
$.ajax({
type: 'Get',
url: "http://api.geonames.org/earthquakesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&username=demo",
success: function(data){
var jsonArray = jQuery.parseJSON(data);
alert(jsonArray.status.message);
}
});
and
$.ajax({
type: 'Get',
url: "http://api.geonames.org/earthquakesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&username=demo",
dataType: 'json',
success: function(data){
var jsonArray = data;
alert(jsonArray.status.message);
}
});
will display the same thing when ran in Firefox firebug. But when you run this in Chrome DevTools it will only work on the bottom one. I hope this fixes your problem.
