The URL is not appearing in the browser's address bar

Below is the code I am using for ajax requests:

// JavaScript Document
function createTeam() {
    var name=document.getElementById("name").value;
    if(name==null || name==""){
        var div3 = document.getElementById("errorMessage");
        var text = "Enter Team";
        div3.style.display = "block";
        div3.style.color = "red";
        div3.style.fontSize = "65%";
        div3.innerHTML = text;
    }else{
        xmlhttp=new XMLHttpRequest();
        xmlhttp.open("POST","/TeamServlet?name="+name+"&task=create",true);
        xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
        xmlhttp.send();
        xmlhttp.onreadystatechange= readResponse;
    }
    function readResponse(){
        if (xmlhttp.readyState == 4)
        {
            response = xmlhttp.responseText;
            $('#button').hide("slow");
            if(response == "false"){
                var div2 = document.getElementById("errorMessage");
                var text = "Unable to create team.";
                div2.style.display = "block";
                div2.style.color = "red";
                div2.style.fontSize = "65%";
                div2.innerHTML = text;
            }
            if(response == "true"){
                var div = document.getElementById("errorMessage");
                var text1 = "Team created.";
                div.style.display = "block";
                div.style.color = "red";
                div.style.fontSize = "65%";
                div.innerHTML = text1;
            }
        }
    }
}

When using this ajax code, the URL does not appear in the address bar of the browser. How can I achieve that? The only URL that appears is after I submit my login form, which is http://localhost:8080/LoginServlet?task=login. However, after this, even if I navigate to other JSPs/servlets, none of those URLs show up. How can I fix this issue with the ajax code?

Answer №1

The concept behind AJAX is to make asynchronous requests in the background without triggering the loading icon of the browser or changing the current URL.

If you're interested in achieving similar effects, consider exploring the HTML5 History API. Since this topic is extensive, I can't provide just one answer, but here are some resources to help you dive deeper:

One challenge you may encounter is limited browser support for this API, so utilizing a polyfill is necessary to ensure cross-browser compatibility. Here's a list of cross-browser polyfills that can assist in meeting this need:

This compilation is managed by the Modernizr team, and the latest version can be accessed at https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills

Answer №2

What is the purpose of showing the URL of an AJAX request in the address bar? Typically, AJAX requests are used to communicate with the server without refreshing or changing the current page. If the goal is to change the URL displayed in the address bar, it's usually done by redirecting the user to a new location, which doesn't require the use of AJAX.
