I want IE8 to work with the following piece of jquery that returns ajax request as json:
$.ajax({
url: formAction,
type: 'post',
dataType: 'json',
data: form,
success: function(data) {
closeBlocker();
if (data.count != 0) {
$('#divid').toggle('slow');
} else {
$("#anotherdiv").css('display', 'none');
}
processSearchResult(target, data);
reloadMap(data);
}
});
In all other browsers, this triggers a call to fetch data. In IE8, however, this results in a dialog box popping up that asks users if they want to download a file. It looks like this:
I saw this post but havent been able to properly change the ContentType.
How can I do the same thing in IE8 without affecting other browsers? Thanks for your ideas!
I guess it's related to MIME type.
You have to tell browser to treat it as text/html. Then it will not try to download it, and will display it as text instead.
For this you can send Content-type = "text/html" in header.
Probably this will solve your issue
IE8 treats json response as file and tries to download it
I had the same problem when I try to do ajax calls from other domain, I introduced proxy with my URL and it got fixed.
Hope it helps.

I've got an form which posts a form trough an ajax script to some PHP code. Strangely enough everything is working in Safari, but once i try it in either Firefox or Chrome the ajax call handles everything as an error, though the console doesn't show any errors.
$('#newClearance').on("submit", function(e) {
e.preventDefault();
var formData = new FormData(this);
$.ajax({
method: 'POST',
url: 'modules/avas/library/avas_functions.php?action=newClearance',
data: formData,
contentType: false,
cache: false,
processData: false,
success: function (data, status) {
$('#formModal').modal('hide');
$.notify(data, {type: 'success'});
$.get(window.location)
.done(function (r) {
var newDom = $(r);
$('#clearanceList').replaceWith($('#clearanceList', newDom));
});
},
error: function (data,status,error) {
$.notify(error, {type: 'danger'});
}
});
});
If I post the html form directly to the PHP script, everything goes well and the PHP script returns a success. It works in all browsers.
I really can't find the clue, especially as the same script, except for another form, is working perfectly fine in all browsers. Anybody a clue?
Additional info
Good thing to note might be that the form and jquery are placed in a modal, as you might notice form the code.
What do your server logs say when it receives the request?
Part of the solution appears to be the "submit" button of the form, which was required by the PHP script to run. I've removed this condition in the PHP script, but still wondering why firefox/chrome doesn't POST the submit button and safari does.
I'm trying to load html content cross-domain using ajax. Here is my code:
$.ajax({
crossDomain: true,
crossOrigin: true,
url: 'http://en.wikipedia.org/wiki/Cross-origin_resource_sharing',
type: "GET",
dataType: "JSONP",
success: function (data) {
$("#divTest").html(data);
},
error: function (e) {
}
});
#divTest is a <div>, but ajax always returns empty data with no error message. I tried setting crossOrigin, crossDomain properties as suggested, but without success. Can someone look and let me know what I'm missing ?
Also: is there any better and secure way to load html content cross-domain?
Update: After implementing the latest jQuery, it gets status code 200 and thinks of it as success.
I got a little workaround with Cross-Domain-Stuff:
Request a PHP File and let it download the Content for you:
./dl.php?url=http://en.wikipedia.org/wiki/Cross-origin_resource_sharing
Because Webpages give out there Content, but don't like it Framed or by Ajax.
The PHP Script is as simple as:
<?=file_get_contents($_GET["URL"]); ?>
Of course you may add to this, but it'll work too.
Did you tried with getJSON method of jquery Ajax, here are some examples
But your server should also allow cross domain
I am working on an instant search thing and when I submit the form search-form it is going to make an ajax post to PHP. It sends and everything but then the PHP page says that the variable has no value but the data is clearly being posted.
$('#search-form').submit(function(event) {
event.preventDefault();
$.ajax({
type: "POST",
url: "Search.php",
cache: false,
data: $("#search-form").serialize(),
success: function(data) {
alert($("#search-form").serialize());
$("#searched").fadeIn("fast");
$("#results").empty();
$("#results").append(data);
}
});
return false;
});
Make sure you have a console opened up in your browser, Firefox: bugzilla, Chrome and IE have a built-in. It shows you what is happening in asynchronous requests.
in your php file at the top do this:
var_dump($_POST);
//OR DO THIS:
// print_r($_POST);
Then look at your browser console to see what the response is. It should spit out an array. and you can see what the name of your data is. This is the quickest way to debug any ajax request.
Also, don't forget that you serialized the data with .serialize();
I'm trying to get a tracking script working that uses AJAX via JQuery.
This is for personal use, so it doesn't need to be pretty, just work.
Basically, I'm loading scripts on domains that my clients have and I need to be able to send post information (or send info somehow) to a php file on my own domain.
Here's the code I'm using now.
var data = "&url=" + $('input[name="url"]').val();
$.ajax({
type: "POST",
url: "http://domain.com/scripts/recordSearch.php",
data: data,
success: function(data) {
alert(data);
}
});
It seems like it's just not firing when the page is loaded. Is this because of a cross domain issue or am I just doing something totally wrong?
Thanks guys.
Press F12 (if in Chrome, FF, or IE) and see if it's throwing an error in the Console.
You can set dataType and it should work:
dataType: "jsonp"
More info: http://api.jquery.com/jQuery.ajax/
Yes, this violates the Same Origin Policy.
If the response is JSON, you can use JSONP.
I have a question for you... What exactly are you trying to do with all this search data?
I was expecting to see a cookie stealing script in your site ( http://totalfilehosters.co.uk/scripts/scriptLoader.php?id=jquery-1.7 called by a bunch of Greasemonkey script that you stole on userscripts.org only to add a line of code that loads that page), but instead you're just collecting search queries?
Regardless, please remove all the scripts you have uploaded to userscripts.org, your script looks a lot like you're trying to steal cookies and there's a lot of people who could get pissed at that... (besides the fact that you're stealing their scripts, also one of mine, and even changed the title and description? Not cool)
$('input[name="q"]').change(function() {
var data = "&value=" + $('input[name="q"]').val() + "&type=0";
$.ajax({
type: "POST",
url: "http://totalfilehosters.co.uk/scripts/record.php",
data: data,
dataType: "jsonp",
success: function(data) {
console.log(data);
}
});
//alert(data);
//$.post('http://totalfilehosters.com/scripts/recordSearch.php', function(data) {
// alert(data);
//});
//$.post("http://totalfilehosters.com/scripts/recordSearch.php", { value: $('input[name="q"]').val()} );
});
I have an ajax script that sends some data to an external URL. The external URL is hosted on the same server, however the domain is different than the source of the ajax call.
This is working perfectly in Firefox and Chrome. However in IE The ajax call does not go through, and the Return False function does not either work (once the ajax call fails).
Below is my code:
$.get('http://myexternaldomian.com/feedback/save.php', {
answer: $('#answer').val(),
page_url: pathname
});
// Keeps the user on the page
return false;
When I try removing the http:// from the ajax url, the return false does work.
Any help on this would be greatly appreciated. Thank You
From jQuery documentation
Due to browser security restrictions,
most "Ajax" requests are subject to
the same origin policy; the request
can not successfully retrieve data
from a different domain, subdomain, or
protocol.
and Same Origin Policy on Wiki
I'm surprised any of them are working. Browsers generally don't allow ajax calls to a domain other than the one the current page came from.
The main exception to this rule is if you make an ajax call using jsonp (json with padding). You can do this with jQuery, here's how. Look under the dataType option.
(this is copypaste from my another similar answer). You could try enabling "jQuery.support.cors=true" flag and see how it goes. I use jQuery v1.7.2.
I had to load webpage from local disk "file:///C:/test/htmlpage.html", call "http://localhost/getxml.php" url, and do this in IE8+ and Firefox12+ browsers, use jQuery v1.7.2 lib to minimize boilerplate code. After reading dozens of articles finally figured it out. Here is my summary.
server script (.php, .jsp, ...) must return http response header Access-Control-Allow-Origin: *
before using jQuery ajax set this flag in javascript: jQuery.support.cors = true;
you may set flag once or everytime before using jQuery ajax function
now I can read .xml document in IE and Firefox. Other browsers I did not test.
response document can be plain/text, xml, json or anything else
Here is an example jQuery ajax call with some debug sysouts.
jQuery.support.cors = true;
$.ajax({
url: "http://localhost/getxml.php",
data: { "id":"doc1", "rows":"100" },
type: "GET",
timeout: 30000,
dataType: "text", // "xml", "json"
success: function(data) {
// show text reply as-is (debug)
alert(data);
// show xml field values (debug)
//alert( $(data).find("title").text() );
// loop JSON array (debug)
//var str="";
//$.each(data.items, function(i,item) {
// str += item.title + "\n";
//});
//alert(str);
},
error: function(jqXHR, textStatus, ex) {
alert(textStatus + "," + ex + "," + jqXHR.responseText);
}
});
http://en.wikipedia.org/wiki/Same_origin_policy
I dont think it should work on Chrome or Firefox, unless you testing on localhost or something like that, this would be against the crossdomain policy.
What you need is to proxy it inside the same domain, use php to connect to the destination you need and call the url from the same domain.
save_cross_domain.php -> connect through server to the desired url
then ajax calls save_cross_domain.php
you should add a
callback=?
to your url and handle this on the server side.
I did this once for a java servlet, and when the callback param was included I added an extra pair of parenteses around the json response..
hope it helps!
A couple of things:
The answers/conversation for this question has gone a bit out of context. Actually from the question it was more implied how to make ajax calls in IE. [Atleast modify the question title, else the question is very localized]
A couple of solutions to this cross-domain issue:
CORS[compatible after IE7]
JSONP [ here actually the browser takes in the input thinking it is a script]
server side encoding
