Q)  How you make AJAX call from a Browser ? Or What is XMLHttpRequest () ?


Ans)

We could make a AJAX call from browser using "XMLHttpRequest". The XMLHttpRequest
object provide a method for exchanging data asynchronously between browser and
server to avoid full page reloads.

Here is the quick example:

             function makeAjaxCall(){
                if(window.XMLHttpRequest){
                                alert("XMLHttpRequest supported by browser ee");
                                xhttp = new XMLHttpRequest();
                                        url='http://localhost:8080/test/post.do';
                                xhttp.open("GET", url, false);  
                                alert("reching your Request ?");
                                xhttp.send();

                        alert(xhttp.responseText);
                            }
                            if(window.ActiveXObject){
                                alert("ActiveXObject supported by browser");
                            }
             }
