       var pos = getImageSrc.lastIndexOf(".");

       if(lastname!=".jpg" && lastname!=".png" && lastname!=".jpeg" && lastname!='.gif'){

           clickUpload(num);
          });
       } 
       num++;
    }
 
 
    function getFullPath(obj) {  //得到图片的完整路径
      if (obj) {
        if (window.navigator.userAgent.indexOf("MSIE") >= 1) {
          obj.select();
          return document.selection.createRange().text;
        }else if (window.navigator.userAgent.indexOf("Firefox") >= 1) {
          if (obj.files) {
            return obj.files.item(0).getAsDataURL();
          }
          return obj.value;
        }
          return obj.value;
      }
    } 
    function ajaxFileUpload(num) {
 
      $.ajaxFileUpload
      (
        {
          url: 'http://xxxx/updateImg', //用于文件上传的服务器端请求地址
          secureuri: false, //是否需要安全协议，一般设置为false
          fileElementId: 'file0', //文件上传域的ID
          dataType: 'json', //返回值类型 一般设置为json
          success: function (data) //服务器成功响应处理函数
          {
            var jsonText = data; 
            console.log(jsonText);
            if(jsonText['status']==1){ 
              if(jsonText['info']!=""){
