原意是点击左侧上传头像，在infoView中显示avatarUpload界面。
问题：在原界面写
<jsp:include page="/avatarUpload.jsp"></jsp:include>
效果都出来了且可以剪切头像：
但是用ajax动态切换界面的时候，界面可以显示，但是不能剪切上传头像。。
js代码：
* function avatarUploadJsp(){
* $(".infoView").empty();//avatarUpload.jsp
* $.ajax({
* url:"http://localhost:8080/Pilgrim/test/goAvatarUploada",
* type:"POST",
* data:{"aaa":"nihao"},
* success:function(data){
* $(".infoView").append(data);
* //$(window).load(data);
* },
* error:function(){
* alert(" ajax trans error");
* }
* });
*
* }
求解，是什么原因造成的，js都引入了
