var handleFileSelect=function(evt) {

      var file = evt.currentTarget.files[0];//reader.result,evt.target.result;

      var reader = new FileReader();

      reader.onload = function (evt) {

        scope.$apply(function(scope){

          scope.myImage = evt.target.result;

        });

      };

      reader.readAsDataURL(file);



    };



    element.find('#fileInput').on('change',handleFileSelect);

base64轉文件

如圖片

var avatarImage = new Image();

  avatarImage.src = baseData;
