首先要引入两个js
script src="/static/js/jquery.js" /script
script src="/static/js/ajaxfileupload.js" /script
注意顺序
$$(function(){ $$('#upload').click(function(){ $$("#submit_info").click( function() { var fileObj = document.getElementById("file_e").files; if (fileObj.length 1) { alert("请选择一个上传文件！"); } else { ajaxFileUpload();function ajaxFileUpload() { $$.ajaxFileUpload( url: '/student/openUpload/', type: 'post', secureuri: false, //是否需要安全协议，一般设置为false fileElementId: 'file_e', //文件上传域的ID dataType: 'json', //返回值类型 一般设置为json success: function (response) { // 处理完数据后前台的回调函数（即后台执行完之后前台接着要做的事） if (response['flag'] == true) { var data = response['msg']; alert(data); window.location = "/student/open/" } else { data = response['msg']; alert(data); error: function (data, status, e)//服务器响应失败处理函数 alert(e);
