由于项目多个文件上传之等于上传总文件大小，就想到用异常上传文件来处理解决，网上找了些资料拿过来不能直接用。其中遇到一些问题，ajaxfileupload.js报错jQuery.handleError is not a function，由于jquery版本1.4.2之前的版本才有handlerError方法，还有就是eaysui filebox获取不到id，$("input[name='testDoc']").attr("id");这样获取，自己整理了下，测试成功
语法：$.ajaxFileUpload([options])
options参数说明：
1、url 上传处理程序地址。
2，fileElementId 需要上传的文件域的ID，即<input type="file">的ID。
3，secureuri 是否启用安全提交，默认为false。
4，dataType 服务器返回的数据类型。可以为xml,script,json,html。如果不填写，jQuery会自动判断。
5，success提交成功后自动执行的处理函数，参数data就是服务器返回的数据。
6，error 提交失败自动执行的处理函数。
7，data 自定义参数。这个东西比较有用，当有数据是与上传的图片相关的时候，这个东西就要用到了。
8, type 当要提交自定义参数时，这个参数要设置成post
jsp代码
<td class="popTD1 bottom_1" style="text-align: right;">测试资料：</td><td class="popTD2 bottom_1"><input type="text" id="testDoc" name="testDoc" style="width: 240px" value="" /></td>
js代码
var testDoc= $("input[name='testDoc']").attr("id");
$.ajaxFileUpload({url: ivs.root + '/qism/rest/consignation/saveTestDoc', secureuri: false, //fileElementId: testDoc, dataType: 'json',type:'post',success : function (data) {if(data.successful){console.log(data);$('#testDocName').val(data.tag.fileName);$('#testDocPath').val(data.tag.filePath);$('#frmConsignationApplyDetail').submit();}else{$.messager.alert("提示", data.message);}} });
服务端代码：
