      Hi All,


           I am facing  issue in excessing XMLHttpRequest class object in my flex  application.

           Currently, I am embedding the javascript method inside my flex application rather than in a separate js file and call that using external interface.

           When I create an instance of XMLHttpRequest class inside that js method of my flex application, nothing happens, but if I put that method in a separate js

           file , then that works fine.

           Any help will be appreciated.

           -Thanks in advance

          Show some code.  I don't understand what it means to embed JS in a flex app.

            Hi ,


            Thanks for the response.


            here is some code:

            private static var FUNCTION_DELETE : String =
               "function (inStr, inAuthHeader, verb)" +
               "{" +
                "var xhr = new XMLHttpRequest();" +
                "xhr.onreadystatechange = function() " +
                "{" +
                 "if (xhr.readyState==4) " +
                 "{" +
                  "if (xhr.status == 204)" +
                  "{" +
            //       some method
                  "}" +
                 "}" +
                "}" +
                "xhr.open(verb, inStr, true);" +
                "xhr.setRequestHeader('Authorization, Basic '+inAuthHeader);" +
                "xhr.send();" +


            ExternalInterface.call(FUNCTION_DELETE, str, encodedString, verb);

            where verb is "DELETE".

              I don't see any mention in the doc that you can pass the code for a function

              as the first parameter to ExternalInterface.call.  Where did you see that?


              Normally the function is in the HTML wrapper.  You could have a generic

              function in the wrapper that would set up this function first then call it

                Thanks for the reply,


                After doing some googling, I found that one and that works fine, if we add  js alert inside that code.

                By the way, If the user wants to add authentication headers and pass that via external interface to the js  and call xmlhttprequest for some url, then it might be possible to intercept that username and password.
