Here's my AJAX code (btw, the PHP file is inside a FileZilla server): var xmlHttpObj=null; var isPostBack=false; function CreateXmlHttpRequestObject( ) { if (window.XMLHttpRequest) { xmlHttpObj=new XMLHttpRequest() } else if (window.ActiveXObject) { xmlHttpObj=new ActiveXObject("Microsoft.XMLHTTP") } return xmlHttpObj; } function MakeHTTPCall_Tags() { var link = "http://phpdev2.dei.isep.ipp.pt/~i110815/recebeXml.php"; xmlHttpObj = CreateXmlHttpRequestObject(); xmlHttpObj.open("GET", link, true); xmlHttpObj.onreadystatechange = stateHandler_Tags; xmlHttpObj.send(); } function stateHandler_Tags() { if ( xmlHttpObj.readyState == 4 && xmlHttpObj.status == 200) { var selectTags = document.getElementById("tag"); var option; var docxml = xmlHttpObj.responseXML; var nodelist = docxml.getElementById("name"); alert(nodelist.length); } } Here's the PHP code:

Now What Introduction You are a Visual Basic® developer and you receive some data in the form of an eXtensible Markup Language (XML) document. You now want to get the information from the XML document and integrate that data into your Visual Basic solutions. You could of course write code yourself to parse the contents of the XML file, which after all is just a text file. However, this isn't very productive and negates one of the strengths of XML: that

However, JS also makes use of "asynchronous" functions to make the program flow faster. This means the program will begin to run the function, but continue on to the next line of code without waiting for the function to complete. Loading images, external files, and URLs are generally handled by async functions. AJAX AJAX (Asynchronous JavaScript and XML) is a technique for communicating with a server and dynamically altering a page without leaving the page. It can be used to send as well as receive information in a variety of formats, including JSON, XML, HTML, and text files. It is made possible with the XMLHttpRequest object, a built-in feature of your browser. This diagram illustrates the basic flow: AJAX is a bit difficult to get working in a cross platform manner (see an example here) but there are quite a few libraries out there that have done the hard work. Following are some examples with p5.js and jQuery, but first, a brief note about callbacks. Callbacks A callback is a function that is passed to another function as a parameter, and called by that other function. A callback function is useful
