Hi all I am first time starting to learn ajax from website w3schools, and I follow the step by step I'm trying to get an AJAX example working but i'm unable to get it working. could you help me please ? thanks you.
这是我的代码
ajax.php
<!DOCTYPE html>
<html>
<body>
<div id="demo"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="loadDoc()">Change Content</button>
<script>
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
document.getElementById("demo").innerHTML = xhttp.responseText;
}
};
xhttp.open("GET", "ajax_info.txt", true);
xhttp.send();
}
</script>
</body>
</html>
推荐答案
您可以使用像这样的ajax，
You can use ajax like this,
<script>
function loadDoc() {
$.ajax({
xhr: function() {
var xhr = new window.XMLHttpRequest();
//progress
xhr.upload.addEventListener("progress", function(e) {
//progress value e
load_progress(e);
}, false);
return xhr;
},
type: "GET",
url: "ajax_info.txt",
success: function(msg) {
//when success //200 ok
document.getElementById("demo").innerHTML = msg;
},
error: function(jqXHR, textStatus, errorThrown) {
//when error
}
});
}
</script>
