废话不多说了，直接给大家贴代码了，具体代码如下所示：
// 上传目标触发点 <input type="file" /> // 引入插件 <script type="text/javascript" src="https://www.jb51.net/{$IMG}/bstage/js/jquery.form.js" language="javascript"></script> /**方法调用**/ setFileUpload({ name: 'fileupload1', backfun: upback1, beforefun: checkUp1, loadfun:loadup, phpUrl: '/ossphp/php/get.php?ft=video' }); // 上传前验证 function checkUp1(n){ // 查看视频大小(mb) var fileObj = document.getElementById(n).files[0]; var relSize = parseInt(fileObj.size/1024/1024); if(relSize > 10){ // 大于10mb alert('提示','视屏超过10MB,请重新上传！'); return false; } // 查看视频类型 var tv_id =document.getElementById(n).value;//根据id得到值 var index= tv_id.indexOf("."); tv_id=tv_id.substring(index).toLowerCase(); if(tv_id!=".rb"&&tv_id!=".rmvb"&&tv_id!=".mp4"&&tv_id!=".flv"){ alert("提示","不是指定视频格式,重新选择"); return false; } return true; } //上传中 function loadup(){ } // 上传成功后操作 function upback1(data){ // data 成功后的参数 } /**上传功能封装**/ function setFileUpload(options){ var n = options.name; var phpUrl = options.phpUrl; var backfun = options.backfun; var beforefun = options.beforefun; var loadfun = options.loadfun; var accessid = ''; var accesskey = ''; var host = ''; var policyBase64 = ''; var signature = ''; var callbackbody = ''; var filename = ''; var dirname = ''; var expire = 0; var upflag = true; if(phpUrl==null || phpUrl==''){console.log('phpurl is null');return false;} if(n==null || n==''){console.log('object is null');return false;} var backfun1 = $.isFunction(backfun) ? backfun : function(success, error){ console.log('no backfun'); }; var beforefun1 = $.isFunction(beforefun) ? beforefun : function(success, error){ return true; }; var loadfun1 = $.isFunction(loadfun) ? loadfun : function(success, error){ return true; }; var obj = $('#'+n); obj.change(function(){ if(beforefun1(n)){ if(n=="fileupload1"){ fileEmb1(n); }else if(n == 'fileupload2'){ fileEmb2(n); }else if(n == 'fileupload3'){ fileEmb3(n); } } }); function fileEmb1(n){ //oss add $("#"+n).attr('name','file'); var file1 = $("#"+n).val(); var fileName = getFileName(file1); phpUrl = phpUrl + '&fname='+fileName; get_signature(); var ldot = fileName.lastIndexOf("."); var filetype = fileName.substring(ldot + 1); $("#"+n).wrap("<form action='"+host+"' method='post' enctype='multipart/form-data'></form>"); $("#myupload1").prepend("<input type='hidden' value=''></input><input type='hidden' value='"+dirname+"."+filetype+"' ></input><input type='hidden' value='"+policyBase64+"'></input><input type='hidden' value='"+accessid+"'></input><input type='hidden' value='200' ></input><input type='hidden' value='"+callbackbody+"'></input><input type='hidden' value='"+signature+"'></input>"); //speed_width进度条类 //percent进度数字类 //load_content上传区域 $('#myupload1').ajaxSubmit({ dataType: 'json', //数据格式为json data:'', beforeSend: function() { loadfun1(); if(!upflag)return false; upflag=false; }, uploadProgress: function(event, position, total, percentComplete) { $('.upck_b').hide(); $('.videspeed').show(); percentComplete = percentComplete>=100?99:percentComplete; var percentVal = percentComplete + '%'; //获得进度 $('.speed_num').css('width',percentVal); $('.persent_em').html(percentComplete); }, success: function(data) { //成功 $('.load_content').html('<em >图片上传</em>'); //上传成功后还原 $("#"+n).attr('name',''); setFileUpload(options); upflag=true; backfun1(data); }, error:function(xhr){ //上传失败 $('.load_content').html('<em >图片上传</em>'); upflag=true; } }); } function getFileName(path){ var pos1 = path.lastIndexOf('https://www.jb51.net/'); var pos2 = path.lastIndexOf('\\'); var pos = Math.max(pos1, pos2) if( pos<0 ) return path; else return path.substring(pos+1); } now = timestamp = Date.parse(new Date()) / 1000; new_multipart_params = ''; function send_request(){ var xmlhttp = null; if (window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else if (window.ActiveXObject) { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } if (xmlhttp!=null && phpUrl) { //phpUrl = '/ossphp/php/get.php?ft=resources'; xmlhttp.open( "GET", phpUrl, false ); xmlhttp.send( null ); return xmlhttp.responseText; } else { alert("Your browser does not support XMLHTTP."); } }; function get_signature() { //可以判断当前expire是否超过了当前时间,如果超过了当前时间,就重新取一下.3s 做为缓冲 now = timestamp = Date.parse(new Date()) / 1000; //if (expire < now + 3) //{ body = send_request() var obj = eval ("(" + body + ")"); host = obj['host'] policyBase64 = obj['policy'] accessid = obj['accessid'] signature = obj['signature'] expire = parseInt(obj['expire']) callbackbody = obj['callback'] dirname = obj['dir'] return true; //} }; }
注:里面的细节还可以继续封装
