i am new in j query ajax.i don't have idea how to fetch data from rest API using j query ajax. here i have created JS function to check whether passing URL working proper or not.
kindly help me.
<script type="text/JavaScript">
$.ajax({
type: "GET",
dataType: "jsonp",
url: "https://www.propertyfinder.ae/en/find-broker/ajax/search?page=1",
success: function(data){
alert(data);
}
});
</script>
You cannot do a cross domain call using ajax. what you can do is to do a php call like :
$website = file_get_contents('http://google.com');
and store it in a text file and access that using your ajax on your server using the same ajax file you have.
i had similar case that i had a php call on scheduler to grab text from url every minute and update a json file. then simply use :
$.getJSON( "ajax/test.json", function( data ) {
//your function
});
or use ajax! whichever you fancy
I am a little new when it comes to JSON and Javascript , so please excuse me if if this is a stupid question, but I have run into a problem that is starting to drive me insane.
On a webpage I am including two scripts; jQuery and a file called "scripts2.js". In the same directory as scripts2.js, I have a JSON file; "settings.json". From within my "scripts2.js" file I am running he following code inside of a function.
var settingsPath = settings.json;
jQuery.getJSON(settingsPath, function (data){
jQuery.each(data, function(index){
console.log("!"+data[index].name);
/*unrelated other stuff */
});
});
Previously the settings.json file looked like this
[
{"name":"Standard Black"},
{"name":"Gold"},
{"name":"Silver"}
]
So naturally when I looked in the Chrome Dev Console the log would print out
!Standard Black
!Gold
!Silver
However, when testing what would happen upon editing my settings.json file I changed "name":"Gold" to "name":"Test".
[
{"name":"Standard Black"},
{"name":"Test"},
{"name":"Silver"}
]
After the json updates I tried refreshing the page but my console log is still printing out
!Standard Black
!Gold
!Silver
...
I am at a loss. I have no idea why the data being retrieved with jQuery.getJSON() is sending the data of my old settings.json even after the changes has been saved. I have perused my .php file (which is generating the HTML) , as well as my included javascript and there is no other mention of another json file or any sort of clone of my json file in any related directory.
I really have no idea what is going on and I am starting to go insane. Does anyone have an idea of what the issue might be?
I dont know if it matters but I am running a XAMPP stack on my localhost. All files (index.php, scripts2.js, and settings.json) are in a directory located inside XAMPP's htdocs folder.
EDIT: Thank you all for the speedy and thorough answers, many of you answered the question I was a bout to ask next. I really appreciate it!
This is because the browser is caching the file from your first request. Simply clear the cache and run it again and the new data will be retrieved.
UPDATE:
To prevent the browser from caching this file, change your AJAX settings like so:
jQuery.ajaxSetup({ cache: false });
Before you make the getJSON call
Try clearing web cache and restart local servers if you have not already
When using jQuery.ajax() instead of the shorthand method, you can disable caching like this:
jQuery.ajax(settingsPath, {cache: false})
jQuery will append a timestamp parameter to your request URL which changes with every request and therefore keeps the browser from caching the response.
To force the browser to get a new version each time you can use cache: false in jQuery.ajax()
$.ajax({
dataType: "json",
url: settingsPath,
cache: false,
success: function (data){
$.each(data, function(index){
console.log("!"+data[index].name);
});
}
});
Pass additional parameter to your requested url which value will change with every request.So,your browser will consider it as new request every time and will not cache the data.
var random = Math.round(new Date().getTime())
var settingsPath = 'settings.json&time=' + random;
jQuery.getJSON(settingsPath, function(data) {
});
});
You can use any algoritham that generate random new value everytime for random for every request.
OR
you can have same things with jQuery#Ajax method
jQuery.getJSON is a shorthand Ajax function, which is equivalent to:
$.ajax({
dataType: "json",
url: url,
data: data,
success: success
});
So, set the optional parameter cache to false (this value by default is always true):
$.ajax({
dataType: "json",
url: url,
data: data,
cache: false, // If set to false, it will force requested pages not to be cached by the browser
success: success
});
Therefore, your getJson becomes:
var settingsPath = settings.json;
jQuery.ajax({
dataType: "json",
url: settingsPath,
data: data,
cache: false,
success: function(data) {
jQuery.each(data, function (index) {
console.log("!" + data[index].name);
/*unrelated other stuff */
});
}
});
I am trying to run this code:
$(document).ready(function () {
$.ajax({
url: 'http://foodfetch.us/OrderApi/locations',
type: 'GET',
success: function(data){
alert(data);
//do work here
}
});
});
For some reason, the AJAX call returns HTML source code, not the JSON object that it should be returning. If you copy the URL into any web browser, the JSON object shows up in plain text.
Can anyone explain what silly thing am I doing wrong here?
As Patrick Evans has pointed out in the comments, the URL in the code links to a page with an embedded frame, I was able to get the code working by using the URL that the frame links to.
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 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
