Check out this link。這個PHP/IFRAME文件上傳是如何工作的?
代碼如何工作?我的意思是IFRAME的src
屬性設置爲#
那麼upload.php
怎麼知道表單已提交?
下面是代碼:index.php
:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Max's AJAX File Uploader</title>
<link href="style/style.css" rel="stylesheet" type="text/css" />
<script language="javascript" type="text/javascript">
<!--
function startUpload(){
document.getElementById('f1_upload_process').style.visibility = 'visible';
document.getElementById('f1_upload_form').style.visibility = 'hidden';
return true;
}
function stopUpload(success){
var result = '';
if (success == 1){
result = '<span class="msg">The file was uploaded successfully!<\/span><br/><br/>';
}
else {
result = '<span class="emsg">There was an error during file upload!<\/span><br/><br/>';
}
document.getElementById('f1_upload_process').style.visibility = 'hidden';
document.getElementById('f1_upload_form').innerHTML = result + '<label>File: <input name="myfile" type="file" size="30" /><\/label><label><input type="submit" name="submitBtn" class="sbtn" value="Upload" /><\/label>';
document.getElementById('f1_upload_form').style.visibility = 'visible';
return true;
}
//-->
</script>
</head>
