I have created a very simple ajax script to interact with a php file that handles the database ineractions.
$(document).ready(function(){
var imgId = $(".imageVoteBtn").attr("id");
$.ajax({
url: "https://myurl.com/getvotes.php",
type: "post",
data: {imgId:imgId},
success: function(data){
$("#voteCount").text(data);
}
})
});
The php files are on a completely separate server and for now it works but we need to move our sitefinity project to another host and they don't allow any connections to the outside.
So now my question is how do I correctly setup database interactions using sitefinity, because the current solution was just a quick hack to get the system working at all. As I understand I should use an ASP.NET solution but because I have never used ASP before, also my knowledge about MVC model is very limited so I don't rightly know where to even begin.
Any help is appreciated

The following code works fine in iPads and iPhone (4,5) in Safari and Chrome. In contrast, the ajax call won't work (runs straight to the onError function) in Android devices and desktop browsers.
When I exchange the absolute URL for a relative one, the success/failure outcomes are reversed in these two groups.
How do I get around this problem (I'm running jquerymobile 1.3.0 beta)? Thanks/Bruce
$(document).ready(function() {
$("#submit").click(function(){
var formData = $("#loginf").serialize();
$.ajax({
type: "POST",
url: "http://mydomain.org/m2/scripts/site/bpg_process.asp?id=lg",
cache: false,
data: formData,
dataType: 'json',
success: onSuccess,
error: onError
});
return false;
});
});
Do you know that cross-domain Ajax calls are not allowed ?
Your problem may be linked to the URL from which you're making the request, and not to the browser you're testing in.
Read this for more details : http://en.wikipedia.org/wiki/Same_origin_policy
The important thing here for you is that the policy excludes different subdomains.
Ex. if you're sending a request from http://www.mydomain.org to http://mydomain.org it will fail, and vice versa.
What i do in your case usually is use the complete URL "/m2/scripts/site/bpg_process.asp?id=lg" without the protocol and host but with the starting "/" so it can be referenced from anywhere in the URL tree.
What is the "relative URL" that you're using and that "doesn't work"?
Like darma has mentioned. "cross-domain Ajax calls are not allowed".
Use absolute "local" pathing instead.
a slash '/' at the beginning of a link referees to the document root.
if you need to refer to an external domain, use ajax to call a local .asp document that calls the external page for you and returns the data you want in json.
Im not sure what this is in asp but in php, curl works.
I have the following Knockout.js code:
this.submitRequest = function () {
var url = '#Url.Action("GetDetails", "BrowseItems")';
$.ajax({
url: url,
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: ko.toJSON(self.searchRequest),
success: function (data) { }
});
};
This ajax call is supposed to hit a GetDetails Action inside a BrowseItems Controller and it does work for my partner, but not for me. The exact same code. I even went so far as blast my whole project and reload it from TFS to make sure that there are no code quirks. So, I know that I have the same code as my partner, yet it works for him, but not for me. This seems to me like I have to set some sort of Visual Studio environment setting. Can anyone help me out with this?
First off how are you testing for whether it is getting hit or not? Debugging? because if so that can be a problem as if you are running through IIS and using the IIS pages and debugging through visual studios local server you will never have visual studio detect a bug on IIS. However lets say you simply are clicking run (debug) which it sounds like. The next thing I would check then is your Global.asax file which has your routes setup. If you dont see something like {controller}/{action} that could possibly be causing a problem. A last suggestion is that instead of wrapping the #Url in ' ' wrap it in " ".
I know there are several screen scraping threads on here but none of the answers quite satisfied me.
I am trying to scrape the HTML from an external web page using javascript. I am using $.ajax and everything should work fine. Here is my code:
$.ajax({
url: "my.url/path",
dataType: 'text',
success: function(data) {
var myVar = $.get(url);
alert(myVar);
}
});
The only problem is that it is looking for the specified url within my web server. How do I use a proxy to get to an external web page?
Due to Cross Site Scripting restrictions, you're going to have to pass the desired URL to a page on your server that will query the URL in question from serverside, and then return the results to you. Take a look at the thread below and the incorporate that into your application and have it return the source when that page is hit by your AJAX function.
How to get the HTML source of a webpage in Ruby
Using a GET request is going to the be easiest way to transfer the URL of the page you want to fetch your server so you'll be able to call something like:
$.ajax("fetchPage.rb" + encodeURI(http://www.google.com))
Because you can't access the side in question directly from the server, you're going to have to pipe the serverside script through a proxy for the request to work, which really kind of depends on your setup. Taking a look at the Proxy class in Ruby:
http://ruby-doc.org/stdlib-1.9.3/libdoc/net/http/rdoc/Net/HTTP.html#method-c-Proxy
My application is located on the server under a separate virtual directory. To access my ASP.NET MVC application users have to go to:
http://server-dev/superApp
I have a problem with Ajax/Json server requests ignoring the "superApp" directory part. Whenever an Ajax request is made Fiddler shows 404 because instead of http://server-dev/superApp/User/GetUsersJson for example, http://server-dev/User/GetUsersJson is called (note the missing superApp name).
Example of an Ajax request:
function GetUsers(id) {
$.ajax({
url: "/User/GetUsersJson/",
data:{ id: id},
datatype: 'json',
type:'post',
success: function (result) {
////Do stuff with returned result
}
});
}
Registered route:
r.Match("User/GetUsersJson", "User", "GetUsersJson");
Where should I look and what can I change to make sure that my application virtual folder is ALWAYS included in all URL requests ?
p.s. Please note that all Javascript/Ajax logic is kept in separate .js files so no RAZOR syntax is available.
Did you try using the HTML helper method ?
url: "#Url.ACtion("GetUsersJson","User)"
EDIT : As per the comment
You may get the Path name using the HTML Helper method and Keep that in a Global variable and access that in the external javascript file
In the view
<script type="text/javascript>
var globalGetJSONPath='#Url.ACtion("GetUsersJson","User)';
</script>
And now you can use it in the external file like this
$.ajax({
url: globalGetJSONPath,
data:{ id: id},
//remaining items....
});
I solved this stuff by passing variable to js that contains hostname+vdir. Because of heavy js url generation.
In other cases Shyju's answer is best way to solve this.
No way to do it without some server-side code generation. Easiest thing would be defining global variable (sorry) holding you application root and initializing it somewhere in master page.
Javascript generation of route urls always was one of the messiest parts of asp.net mvc.
I want to get xml data from google server using it's API. so, i can't make any changes to response. So, How do I make this call that work for me:
$.ajax({
type: 'POST',
url: 'https://www.google.com/accounts/ClientLogin',
contentType: 'application/x-www-form-urlencoded',
data: { accountType : "HOSTED", Email : ""+Adminemail+"", Passwd : ""+adminpass+"", service : "cp"}, // cp for contact service..
success: function (response) {
alert(response); });
I want make some GET, PUT, DELETE call as well so, I don't want to use any function like $.getJSON();I want to make it possible through $.ajax() only.
I think only way to do this is use of server side scripting language.
Most browsers won't allow cross site scripting. (An ajax call that is not in your own domain).
So if you want to call such an url (https://www.google.com/accounts/ClientLogin), do it server side.
Cross domain posting is blocked by the browser. You could write your own browser. Since this is probably not an option, you could post to your own server and from there post to the other server. I think you can post data to another server using cUrl if you're using PHP.
There's a nice example here.
The third party must provide a jsonp api.
