在实际开发中其实我们可以给用户一些提示，比如上传成功或者上传失败，废话不多说，走码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="jq183.js"></script>
<script>
function ajaxup(){
var ifname = ‘up‘+Math.random();
$("<iframe name=‘"+ ifname +"‘ height=‘0‘ width=‘0‘ frameborder=‘0‘ ></iframe>").appendTo($(‘body‘));
$(‘form:first‘).attr(‘target‘,ifname);
//return false;
}
</script>
</head>
<body>
<p id="mess"></p>
<form action="9.php" method="post" enctype="multipart/form-data" onsubmit="return ajaxup();">
<input type="file" name="pic"> <br> <br>
<input type="submit" value="GO">
</form>
<iframe src="" frameborder="0"></iframe>
</body>
</html>
<?php
if(empty($_FILES)){
exit(‘No file‘);
}
$errs = $_FILES[‘pic‘][‘error‘] == 0 ? ‘success‘:‘error‘;
echo "<script> parent.document.getElementById(‘mess‘).innerHTML = ‘$errs‘ </script>";
