The code below does not run on IE and Chrome, error in xhttp.send(), but Mozilla works. What happens?
<!DOCTYPE html>
<html>
<body>
<div id="demo">
<h2>The XMLHttpRequest Object</h2>
<button type="button" onclick="loadDoc()">Change Content</button>
</div>
<script>
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("demo").innerHTML = this.responseText;
}
};
xhttp.open("GET", "teste.txt", true);
xhttp.send();
}
</script>
</body>
</html>
Error message:
ajax.html:20 Failed to load file://D:/Desktop/studentJs/ajax/teste.txt: Cross origin requests are only supported for Protocol schemes: http, data, Chrome, Chrome-Extension, https
Can you tell us the full error message?

The message says what is wrong: the requested URL must be in one of these mentioned protocols, not with
file://. It is certainly duplicate on the site, so I advise to use the search. If I find, I will put here.– Woss
