4. Js

导入 uploadV3.js

<script defer>

 

var saveDir="00upQ4";

saveDir=encodeURIComponent(saveDir);

uploadSrv=new  AtiUploadV3("#userHeadImage");

uploadSrv.up_url=$approot+"/upServlet?savepath="+saveDir;

 

uploadSrv.upload_finish_handler=function(data){

data=data.trim();

console.log("upload_finish_handler:"+ data);

console.log("上传结束返回结果:"+data);

$("#thumb").val(data);

//图片本地预览

var url=getPicSrc4createObjectURL("userHeadImage");

console.log(url);

$("#headImage").attr("src",url);

};

</script>

 

 

5. uploadV2.js

// JavaScript Document

function AtiUpload()

{

this.up_url;

this.upload_finish_handler;

}

AtiUpload.prototype. upload=function()

{

var self=this;

try{

 $("#process_div").progressBar(99);

}catch(e){

console.log(e);

}

var fd = new FormData();

//fd.append("upload", 1);

fd.append("upfile", $("#filex").get(0).files[0]);

$.ajax({

url: this.up_url,

type: "POST",

processData: false,

contentType: false,

data: fd,

success: function(d) {

console.log(d);

console.log("----fini");

//$("#file_val").val(d);

// writeCookie("file_url_frmJS",$("#file_val").val(),10);

 self.upload_finish_handler(d);

 upload_finish();

}

});

}

6. upServlet &  FileUploadService {  

 

7. 注意::去除struts的干扰

当项目有struts框架,配置了监控所有的url  /*的时候 (默认)。。会获取不到数据,需要去除struts的干扰

 

  <constant name="struts.action.excludePattern" value="/upServlet,
