Before using the ajaxForm method, you first need to install the form.js plug-in, which is available online;
First, let’s talk about usage. AjaxForm can receive 0 or 1 parameters. This parameter It can be a variable, an object or a callback function. This object mainly has the following parameters:
var object= { url:url, //form提交数据的地址 type:type, //form提交的方式(method:post/get) target:target, //服务器返回的响应数据显示的元素(Id)号 beforeSerialize:function(){} //序列化提交数据之前的回调函数 beforeSubmit:function(){}, //提交前执行的回调函数 success:function(){}, //提交成功后执行的回调函数 error:function(){}, //提交失败执行的函数 dataType:null, //服务器返回数据类型 clearForm:true, //提交成功后是否清空表单中的字段值 restForm:true, //提交成功后是否重置表单中的字段值,即恢复到页面加载时的状态 timeout:6000 //设置请求时间,超过该时间后,自动退出请求,单位(毫秒)。 } ajaxForm js的code $(function(){ $("form").ajaxForm(object); })

php upload upload class upload.class.php file
'empty_name','type'=>$type); echo json_encode($arr); exit(); } return true; } /** *检测文件类型 */ public function check_type($get_type) { if (( $get_type == ".docx" ) || ( $get_type == ".doc" )) { //这里只是判断上传word文档可以自己添加 }else{ $type = "check_type"; $arr = array('error'=>'format','type'=>$type); echo json_encode($arr); exit(); } return true; } /** *检测文件大小 */ public function check_size($get_file) { if ( $get_file != "" ) { if ( $get_file > $this->file_size ) { $arr = array('error'=>'large'); echo json_encode($arr); exit(); } }else{ return false; exit(); } return true; } /** *文件保存 */ public function save_file($file_type,$file_tmp_name) { $rand = rand(1000, 9999); $pics =date('YmdHis') . $rand . $file_type; $path = $this->file_path."/".$pics; $result = move_uploaded_file($file_tmp_name, $path); if($result){ return $pics; }else{ return false; exit(); } } } ?>
ajax submit php processing file upload.php
check_file($get_fileName); if($check_result){ $result_type = $up_obj->check_type($get_fileType);//检查文件类型 if($result_type){ $result_size = $up_obj->check_size($get_fileSize);//检查文件大小 if($result_size){ $pics = $up_obj->save_file($get_fileType,$get_TmpFiles); //文件上传保存 $size = round($get_fileSize/1024,2); $arr = array( 'name' => $get_fileName, 'pic' => $pics, 'size'=> $size, 'error' => 2, 'list' =>$_POST['list'] ); if($pics){ //检查文件上传状态 echo json_encode($arr); } } } } ?>
