How to make ajax call cross domain

I have access to the API, which is a JSP file and is in JSON format. I am trying to extract this data from a JSP page in a PHP script and process it and then save it in my MySQL server.

The JSON string is valid on the JSP page that I checked in several JSON formatters and an online validator.

This is my code that I use to get JSON data from the page, but every time my ajax call fails.

$('#button').click(function(e){
var url = 'http://xxxxx:8080/StudentAPI/index.jsp';
$.ajax({
    url : url,
    dataType : 'json',
    success : function(response) {
        alert('Success');
    },
    error : function(request, textStatus, errorThrown) {
        alert(request+textStatus+errorThrown);
    }
});
e.preventDefault();
})

Please help me, and any suggestion to make it better is always welcome.

You are making an ajax call to the cross domain. This way it will not work if you try it like a regular ajax call.

One way is similar to

  • "Access-Control-Allow-Origin" "*" , ajax.

  • jquery ajax 'crossDomain' 'true' .

jsonp

, .

UPDATE

w3c, , Java. . Java.

, , ajax, "Access-Control-Allow-Origin", "*" .
