js引用layer.js,ajaxfileupload.js,xlsx.core.min.js
layer.js是个很不错的弹出层解决方案
git地址：https://github.com/sentsin/layer
ajaxfileupload.js负责文件上传，不过由于很久没有更新，对于jquery1.4之后的版本不兼容，需要在源码处jQuery.extend中添加handleError函数
git地址：https://github.com/carlcarl/AjaxFileUpload
handleError: function( s, xhr, status, e ){
// If a local callback was specified, fire it
if ( s.error ) {
s.error.call( s.context || s, xhr, status, e );
}
// Fire the global callback
if ( s.global ) {
(s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError", [xhr, s, e] );
}
} ,
