在AJAX和jQuery中使用HTML5文件上传
提交表单后，赶上提交过程并尝试运行以下代码片段进行文件上传-
// File 1
var myFile = document.getElementById('fileBox').files[0];
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = myFunc;
function myFunc(event) {
var res = event.target.result; var fileName = document.getElementById('fileBox').files[0].name;
$.post('/myscript.php', { data: res, name: fileName }, continueSubmission);
}然后，在服务器端（即myscript.php）-
$data = $_POST['data'];
$fileName = $_POST['name'];
$myServerFile = time().$fileName;
//防止覆盖
$fp = fopen('/uploads/'.$myServerFile,'w');
fwrite($fp, $data);
fclose($fp);
$retData = array( "myServerFile" => $myServerFile );
echo json_encode($retData);
