php中ajaxfileupload.js怎么使用

$target_dir = "uploads/"; // 上传文件保存的目录$target_file = $target_dir . basename($_FILES["file"]["name"]); // 上传文件的路径$uploadOk = 1; // 上传是否成功的标识if(isset($_POST["submit"])) {$check = getimagesize($_FILES["file"]["tmp_name"]);if($check !== false) {echo "File is an image - " . $check["mime"] . ".";$uploadOk = 1;} else {echo "File is not an image.";$uploadOk = 0;}}if ($uploadOk == 0) {echo "Sorry, your file was not uploaded.";} else {if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {echo "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.";} else {echo "Sorry, there was an error uploading your file.";}}

$.ajaxFileUpload({url: 'upload.php', // 处理文件上传的PHP文件路径secureuri: false,fileElementId: 'file_upload', // 文件input元素的id属性dataType: 'json',success: function (data, status) {// 文件上传成功后的处理逻辑alert(data.message);},error: function (data, status, e) {// 文件上传失败后的处理逻辑alert('File upload failed.');}});

以上是使用ajaxfileupload.js进行文件上传的基本步骤。根据你的具体需求，你可能需要进行一些额外的配置和处理。
