前臺js中程式碼

if(json.data.headPhoto!=null && json.data.headPhoto!=""){
                    	$('#headPhoto').attr('src', contextPath + '/o2oUser/getPhoto?photoURL=' + json.data.headPhoto);
                    }else{
                    	$('#headPhoto').attr('src', basePath + '/dist/img/SF.jpg');
                    }
