Is there a straightforward method to populate a div by fetching a PHP script (and sending data like POST or GET) to determine what data should be returned?
I'm searching for a solution that doesn't rely on a library... All I seem to come across are examples using prototype and jquery.
Has anyone accomplished this without using a library?
let request;
function displayUser() {
request = createHttpRequestObject();
if (request == null) {
alert("Your browser does not support HTTP requests");
return;
}
let url = "yourpage.php";
url = url + "?q=" + str;
request.onreadystatechange = handleStateChange;
request.open("GET", url, true);
request.send(null);
}
function handleStateChange() {
if (request.readyState == 4) {
document.getElementById("yourdiv_id").innerHTML = request.responseText;
}
}
function createHttpRequestObject() {
if (window.XMLHttpRequest) {
return new XMLHttpRequest();
}
if (window.ActiveXObject) {
// code for IE6, IE5
return new ActiveXObject("Microsoft.XMLHTTP");
}
return null;
}
Check out this code for a great example of how to manage XHR objects with some helpful syntax.
This "library" is less than one hundred lines long and does exactly what you need it to without any unnecessary extras.
