i have wsdl file and i need get data from. How i can do this ? i'm trying do this with ajax
like this:
jq.ajax({
url: 'http://url.wsdl',
type: 'get',
success: function(data){
alert("OK " + data);
},
error: function (x, y, z) {
alert("ERROR");
}
});
what i do wrong ?
Any other way to get data from wsdl web service using javascript, jquery and etc. is?
I think what you are missing is a data: {}
I read that there was some sort of bug if you did not include that when using $.ajax
Oh, and most likely you are going to need dataType: "json" or whatever datatype the service is using.
Here is an example i am using against an online webservice:
jQuery.support.cors = true; //enables cross domain queries for Ajax
$('#jqueryBtn').click
(function ()
{
$.ajax
(
{
type: "GET",
url: "http://www.webservicemart.com//uszip.asmx/ValidateZip",
data: { 'ZipCode': '22553' },
dataType: 'html',
success: jqSuccess,
error: jqError
}
);
}
Hopefully you can use this example to fix your own code
http://forum.jquery.com/topic/jquery-ajax-to-call-a-wsdl-web-service
The following link should explain why you cannot use AJAX for cross domain queries:
http://www.w3schools.com/xmL/xml_parser.asp:
Access Across Domains
For security reasons, modern browsers do not allow access across
domains.
This means, that both the web page and the file it tries to load,
must be located on the same server.
The examples on W3Schools all open XML files located on the W3Schools
domain.
If you want to use the example above on one of your web pages, the file you load must be located on your own server.
You can create a proxy web page in your web server to access to WSDL web service and return result to the AJAX request

I'm trying to make a wikipedia search bar. The idea is to send a new AJAX request every time search input is changed. I'm using https://www.mediawiki.org/wiki/API:Search_and_discovery as a guideline.
var search = $('#search');
search.keyup(function() {
if (search.val() === '') {
result.html('');
}
$.ajax({
url: '//en.wikipedia.org/w/api.php',
data: {
action: 'query',
list: 'search',
format: 'json',
srsearch: search.val()
},
dataType: 'jsonp',
success: function(response) {
console.log("success!");
}
});
});
However, success function is not even triggered.
On any keypress the error I get is this ("d" pressed):
jquery-2.1.1.min.js:4 GET file://en.wikipedia.org/w/api.php?>callback=jQuery21107844703783826772_1484403407494&action=query&list=search&srse>arch=d&format=json&_=1484403407495 net::ERR_FILE_NOT_FOUND
Thank you in advance for any help or guidance!
Well, you're probably trying to do a AJAX request without a local server (opening your file directly in the browser).
First of all, your url options starts with //en... (without the protocol). It indicates that it'll construct your full url using the same protocol you're using. In this case: file://. That's because your browser is trying to reach file://en.wikipedia.org/....
So, you can set your url to https://en.wikipedia.org/w/api.php to make it work.
Just replace:
url: '//en.wikipedia.org/w/api.php',
with:
url: 'https://en.wikipedia.org/w/api.php',
Looks like you're running it from a simple html file located in your filesystem, in other words not running it from a web server (even local).
Try calling the api with
url: 'https://en.wikipedia.org/w/api.php'
or run the file from a web server (can be a local one).
I create an account with yaler, to comunicate with my arduino yun. It works fine, and i'm able to switch on and off my leds.
Then i created a web page, with a button that calls an ajax function with GET method to yaler (yaler web server accept REST style on the URL)
$.ajax({
url: "http://RELAY_DOMAIN.try.yaler.net/arduino/digital/13/1",
dataType: "json",
success: function(msg){
var jsonStr = msg;
},
error: function(err){
alert(err.responseText);
}
});
This code seem to work fine, infact the led switches off and on, but i expect a json response in success function (msg) like this:
{
"command":"digital",
"pin":13,
"value":1,
"action":"write"
}
But i get an error (error function). I also tried to alert the err.responseText, but it is undefined....
How could i solve the issue? Any suggestions???
Thanks in advance....
If the Web page containing the above Ajax request is served from a different origin, you'll have to work around the same origin policy of your Web browser.
There are two ways to do this (based on http://forum.arduino.cc/index.php?topic=304804):
CORS, i.e. adding the header Access-Control-Allow-Origin: * to the Yun Web service
JSONP, i.e. getting the Yun to serve an additional JS function if requested by the Ajax call with a query parameter ?callback=?
CORS can probably be configured in the OpenWRT part of the Yun, while JSONP could be added to the Brige.ino code (which you seem to be using).
I had the same problem. I used JSONP to solve it. JSONP is JSON with padding. Basically means you send the JSON data with a sort of wrapper.
Instead of just the data you have to send a Java Script function and this is allowed by the internet.
So instead of your response being :
{"command":"digital","pin":13,"value":0,"action":"write"}
It should be:
showResult({command:"analog",pin:13,value:0,action:"write"});
I changed the yunYaler.ino to do this.
So for the html :
var url = 'http://try.yaler.net/realy-domain/analog/13/210';
$.ajax({
type: 'GET',
url: url,
async: false,
jsonpCallback: 'showResult',
contentType: "application/json",
dataType: 'jsonp',
success: function(json) {
console.dir(json.action);
},
error: function(e) {
console.log(e.message);
}
});
};
function showResult(show)
{
var str = "command = "+show.command;// you can do the others the same way.
alert (str);
}
My JSON is wrapped with a showResult() so its made JSONP and its the function I called in the callback.
Hope this helps. If CORS worked for you. Could you please put up how it worked here.
I am trying to access a WebAPI (in the same server but different IP). It works like a charm in IE 10 . But in IE 8 it goes worse. I have included $.support.cors=true and also included the jQuery.XDomainRequest.js which I got from
https://github.com/MoonScript/jQuery-ajaxTransport-DomainRequest/blob/master/jQuery.XDomainRequest.js
For the GET request it is working, but for the post its throwing out error. I learned that for POSt content type should be text/plain.
I tried to send my data as a plain text, probably the server is not parsing it properly.
I also tried jsonp as well, but didn't work
I am putting down my webapi call . Please suggest on how can I get this working. Thanks a lot .
function Authenticate() {
var UserInfoRequest = {
Email: $("#txtEmail").val(), SubDomain: subDomainName
};
//UserInfoRequest ="Email="+$("#txtEmail").val()+"&SubDomain="+subDomainName;
$.ajax({
url: defaultAPIurl + "Login/UserExistOrDualRole" ,
type: "POST",
dataType: 'json',
data: UserInfoRequest ,
success: function (data) {
//do something
},
error: function (data) {
Showerror();
return;
}
});
return false;
}
ASP.NET WEB API support CROS need extra library. Check this post:CORS support for ASP.NET Web API
Modified your project as this post written,it's will be working.
tips:The two library at their NightBuild Nuget server when I used it.
I am planning to create a Restful API in yii for cross domain communication. As what I have researched, cross domain communication can only be done via jsonp and my implementation is as follows:
UsersController:: actionCrossDomain
public function actionCrossDomain(){
$this->layout=false;
$data['data']['User']['name']= 'Johny';
$this->_sendResponse(200, CJSON::encode($data),'application/json');
}
UsersController::_sendResponse methdod it is the same as you can see in :Click here
On another server that i configured using virtual host, I am invoking the above method via ajax:
$( document ).ready(function() {
$.ajax({
type: "POST",
dataType: "jsonp",
url:'http:'http//uxaserver.local/alpha2/app/users/crossDomain' ,
data: null,
processData: false,
crossDomain: true,
contentType: "application/json",
success: function (data) {
console.log("done");
},
error: function (request, status, error) {
console.log(request);
}
});
});
The issue is my firebug is is complaining that : SyntaxError: invalid label
My requirement is such because I am helping my client's to do some customized analytic to his other websites and I need to put a script in his web pages of different domains so that the analytic data is recorded in the main server. I understand that I need to use the rest interface to communicate thus I am taking this approach. I am not sure if I have taken the right approach and please advice. I want to make it in a way where a client has an api key and can communicate with the api provided by me.
Is there any other approach to do this? Rather than jsonp?
As i see this string contents error
url:'http:'http//uxaserver.local/alpha2_uxarmy/app/users/crossDomain' ,
Should be
url:'http//uxaserver.local/alpha2_uxarmy/app/users/crossDomain' ,
I am new to Javascript. I need to parse XML using javascript or jQuery which is another server. I tried by using the below code. But when I executed it, it was not going to success method.
I was able to parse the XML which is in the same folder. Is it possible in javascript to access content from another server. I read the Same Origin Policy.
I was able to get the success message, but cant get the xml data
$.ajax({
type: 'GET',
url: 'http://10.47.5.69/myxml.xml',
dataType: "xml",
success: function(data){
alert('success');
$(data).find("Node").each(function() {
alert($(this).find("element").text());
});
},
error: err
});
function err(xhr, reason, ex)
{
alert('xhr.status: ' + xhr.status);
alert('ex "'+ex);
}
You cannot load something from another server due to cross-domain security checks.
However for javascript, there is a workaround: the JSONP technique: http://en.wikipedia.org/wiki/JSONP
It is used for JSON data but it can just as well be used for any string data. But it will only work if you have some degree of control (i.e. can install a script) on that server.
Another alternative is to proxy that URL on your own server. That might be easier.
