//-- 去掉sourceType为拍照

// Upload files to server

上传后更新图片地址

/* 修改我的资料 */
module.controller('ModifyMemberInfoCtl', function($scope,  $http) {
    
    $scope.submit=function(){
    
    }
    
    $scope.setImg=function(){
        
        navigator.camera.getPicture(function(imageURI){
                 var url=apiUrl+"/upload.aspx";
                 //alert(imageURI + "--" +url);
                  modal.show();
                 uploadFile(imageURI,url,function(path){ 
                 setTimeout( function(){modal.hide();},3000);
                 $scope.Avatar=imgUrl + path +"?width=280&height=280";
                 $scope.$apply();
                 });
