httpRequest.responseXML – returns the response as an XMLDocument object you can traverse with JavaScript DOM functions,Make requests to the server without reloading the page,We'll also add a line to our event handler to get the user's data from the text box and send it to the makeRequest() function along with the URL of our server-side script:,What should this function do? First, the function needs to check the request's state. If the state has the value of XMLHttpRequest.DONE (corresponding to 4), that means that the full server response was received and it's OK for you to continue processing it.

// Old compatibility code, no longer needed.
if (window.XMLHttpRequest) { // Mozilla, Safari, IE7+ ...
   httpRequest = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE 6 and older
   httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
