what I need to do is read the content of a "public" google spreadsheet (by public I mean that I saved the sheet clicking on "File > Publish to the web", so it's accessible without the need to be logged in into a google account), and, why not, write something into it too.
googlin' around, I found that I can access the sheet and get the xml equivalent of the sheet content with something like
https://spreadsheets.google.com/feeds/list/<sheetCode>/od6/public/values
It works great if I load that url into a browser. But I need to find a "javascript-way" to get and handle the returned value, ie the xml (or json, but xml would be preferable).
I tried to use an ajax call, but I think there's something messy with the protocol.. I can't get the server response correctly.
$.ajax({
type: "GET",
url: "https://spreadsheets.google.com/feeds/list/<sheetCode>/od6/public/values",
success: function(data){alert("yeah");},
error: function(){alert("fail..");},
dataType:"xml",
});
I also tried to get the json instead of xml, adding "?alt=json" to the url and changing the datatype, but I still have the problem..
Any idea / suggestion?
Thanks in advance, best regards
You need to request with a JSONP call and you need to specifiy a callback - method. This can be done in jQuery using:
var url = 'https://spreadsheets.google.com/feeds/list/<CODE>/od6/public/values?alt=json-in-script&callback=?';
jQuery.getJSON(url).success(function(data) {
console.log(data);
}).error(function(message) {
console.error('error' + message);
}).complete(function() {
console.log('completed!');
});

I want to call the Google API from JavaScript code.
I have a URL to search nearby locations like this:
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=ww.www,yy.yyy&radius=50&key=XXXXX
When I run that through browser I get the correct JSON result.
But I want to get the JSON response from my JavaScript code.
I don't want to show these locations in Google Maps, just to get the JSON object and manipulate it according to my needs.
I tried to send it via an Ajax call, but it gives an error.
This is what I am using:
//remember to add your API KEY to the url below.
$.ajax({
url: 'https://maps.googleapis.com/maps/api/geocode/json?address=UK&key=<KEY-GOES-HERE>',
type: 'GET',
success: function(res) {
alert(res.status); //responds with "OK"
}
});
You will need to use the jQuery tag for it to function, as its using the jQuery ajax function:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Use the places-library of the Maps-Javascript-API: https://developers.google.com/maps/documentation/javascript/places#place_search_requests
You may use the nearbySearch of this library also without a map(but when you print data without a map you must include the Logo)
The URL you've posted may not be requested via AJAX, because the server doesn't send the appropriate headers for a XDomainRequest
I'm trying to use the API from https://developer.forecast.io and I'm getting a JSON response, this is the first time I'm using an API and all I really need to know is, how do I assign the JSON response I get back from their API to elements on my page. Thanks!
This is done with a script-tag in my header:
script(src='https://api.forecast.io/forecast/APIKEY/LAT,LON')
http://api.jquery.com/jQuery.ajax/ you need to add a success callback, at the bottom of that page are examples you can look at.
EDIT
ok i saw that you are using a script tag with the request, since the api is outside your current domain you need to make a JSONP request
$(document).ready(function(){
$.ajax({
url: 'https://api.forecast.io/forecast/APIKEY/LAT,LON',
dataType: 'jsonp',
success: function(data){
//do whatever you want with the data here
$("body").append(JSON.stringify(data));
}
});
});
off course you need to make some tweaks to that piece of block but you get the idea
What you're looking for is DOM manipulation. DOM is the HTML Document Object Model, an object representation of the HTML comprising a document. There are a lot of ways to go about this, but one of the more popular Javascript libraries for performing this task is jQuery. See their help documentation category on manipulation for more information.
OK, based on your clarification, you're not yet using AJAX. I say "not yet", because you're going to need to. Again, I'll recommend jQuery for that, and their own documentation as the best resource. For a simple "get", your easiest option is the getJSON method.
So, at a very simple level you might do something like:
$(function(){
$.getJSON('url_to_api', function(data) {
$("#SummaryBox").append("<div>" + data.hourly.summary + "</div>");
}
});
I am trying to make a simple ajax request(cross-domain) using Json.
Here's my code :
$("#unsub").live('click', function() {
$.ajax({
url: urly ,
type:'GET',
dataType:"json", //type JSON
success: function(data) { //do something
}
});
});
However, the response I am getting from the server is a html Div
<div id="handler"></div>
On button click I get an error on success "XML can't be the whole program".
Please note : i have to USE json to make the call no matter what and the call will always return a div. using jquery 1.3.2
Any help would be highly appreciated.
Thanks for the time.
Most of the time you need to provide the remote server a "callback" in url for the jsonp to be wrapped in. If API is not set up for JSONP, you need to use other methods to egt the JSOn with javascript. First check that API will deliver jsonp, and if so what params to put in the url
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
I have the following code I am using to send data to a MailChimp Newsletter List (API v3). Everytime I remove the type: POST from the function it attempts to post the data via GET and it sends the data properly (ok response in MailChimp API dashboard). When testing this in the browser (FF) I get a .part file with "true" response.
$(function(){
$("a#test").click(function(e){
e.preventDefault()
data = {
"apikey" : "667378947",
"id" : "90298590285",
"email_address" : "test#getmoxied.net",
"output" : "json"
}
$.ajax({
type: "POST",
url: 'http://us2.api.mailchimp.com/1.3/?method=listSubscribe',
data: data,
success: function(data){
alert(data);
},
error: function(){
alert("err");
}
})
});
});
Im pulling my hair out on this one, any insight is greatly appreciated.
Thanks in advance,

There is an undocumented endpoint that uses JSONP to do cross-domain ajax requests.
Just change 'post?' to 'post-json?' and add '&c=?' to the end of the standard url to get the JSONP endpoint. This doesn't requires the API key to be exposed on the client-side, or the creation of a server-side view.
I wrote a jQuery plugin that uses this method, if that's useful at all
https://github.com/scdoshi/jquery-ajaxchimp
The main issue is what jc commented on your original post - this simply won't work due to Same Origin Policy issues. Firebug is not as vocal about why the GET call fails, but that's why it returns no data. If you watch that with the POST, you'll see Firefox doesn't even make the call. Chrome's js console on the other hand straight explains the Same Origin policy to you.
All in all, this is a very good thing if for no other reason than it prevents you from publicly publishing your account's API Key, which is a very bad thing to do. If the reason why doesn't immediately sink in, go read through the large number of methods available in the API and then realize that all you need to access them is that API Key.
The correct way to do this is to POST data back to your server, then make the request from there. There are several fully built PHP examples (one using jquery, even), here.
e.preventDefault();
data = {
"apikey" : "667378947",
"id" : "90298590285",
"email_address" : "test#getmoxied.net",
"output" : "json"
};
