前台通过ajaxfileupload插件上传提价数据：
$.ajaxFileUpload({
url : "${ctx}/h5/h5preventiveEdu/updateEdu",//增加与修改通用
secureuri : false,
fileElementId : elementId,
dataType:'text/html',
async : false,
data : {
name : elementId,
fileds : elementId,
optType : obj['optType'],
title : obj['title'],
content : obj['content'].replace(/[\n\r]/g, "<br>").replace(/<br><br>/g,"<br>"),
id : preventiveEduId
},
success : function(data, status) {
$this.removeData("ajax");
if(opt == 'add'){
swal({title:"", text:"成功！请等待后台视频处理", confirmButtonText:"确定"});
}
window.location.href = "${ctx}/h5/h5preventiveEdu/police/preventiveEdu";
},
error : function(data, status, e) {
$this.removeData("ajax");
}
});
