我想在提交表单时呈现等待时间动画，但我更喜欢使用SweetAlert而不是标准加载图像。
这是基本代码：
$("form").submit(function (e) {
e.preventDefault(); // stops the default action
$("#loader").show(); // shows the loading screen
$.ajax({
url: test.php,
type: "POST"
success: function (returnhtml) {
$("#loader").hide(); // hides loading sccreen in success call back
}
});
});这是 SweetAlert 想要实现的代码：
window.swal({
title: "Checking...",
text: "Please wait",
imageUrl: "images/ajaxloader.gif",
showConfirmButton: false,
allowOutsideClick: false
});
//using setTimeout to simulate ajax request
setTimeout(() => {
window.swal({
title: "Finished!",
showConfirmButton: false,
timer: 1000
});
}, 2000);<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
