我想在响应完成之前显示我在 php 中刷新的信息。我搜索并编写了以下代码，进度完成后我得到响应，但我想在 php 脚本进程和用户查看正在执行的操作时显示结果。我怎样才能做到这一点？谢谢我的代码：<!doctype html><html lang=""><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title></head><body><form> <input type="text" id="ip" value="127.0.0.1"> <button type="button" onclick="save()">send</button></form><iframe id="loadarea"></iframe><script src="jquery-3.5.1.min.js"></script><script type="text/javascript"> function save() { let ip = $('#ip').val(); let req = $.ajax({ type: 'POST', url: 'xample.php', data: { ip: ip } }); ************************************************************** * * * req.progress(function (res) { * * document.getElementById('loadarea').src = 'nmap.php'; * * }); * * * ************************************************************** req.done(function (res) { if (res == "cant") { console.log('fail'); }else console.log('ok' ); }); }</script></body></html>

为了显示进度，您可以设置检查进程状态的时间间隔。如下所示：
<script type="text/javascript">
function save() {
let ip = $('#ip').val();
let req = $.ajax({
type: 'POST',
url: 'xample.php',
data: {
ip: ip
}
});
req.done(function (res) {
//================================
// set interval for check status of progress every 1 sec
setInterval(() => {
let reqStatus = $.ajax({
type: 'POST',
url: 'xampleStatus.php',
data: {
ip: ip
}
});
req.done(function (resStatus) {
console.log(resStatus);
});
}, 1000);
//================================
if (res == "cant") {
console.log('fail');
} else
console.log('Start progress');
});
}
</script>

我用这种方式解决了这个问题：
<script src="jquery.min.js"></script>
<script type="text/javascript">
function save() {
var ip = $('#ip').val();
var data = new FormData();
data.append('ip', ip);
var xhr = new XMLHttpRequest();
xhr.open('POST', 'example.php', true);
xhr.send(data);
xhr.onreadystatechange = function () {
if (xhr.status === 200) {
if (xhr.readyState === XMLHttpRequest.LOADING) {
$('#loadarea').html(xhr.response);
}
if (xhr.readyState === XMLHttpRequest.DONE) {
$('#loadarea').append("finished!!!");
}
}
}
}
</script>
