By using Bean Shell Form Data Store, we are able to load and update our Environment Variable values by using a form.

Let's create a form with each Text Field to represent a Environment Variable in our app and set all the field id to the ID of the Environment Variable.

โดยใช้ Bean Data Store แบบฟอร์มเราสามารถโหลดและปรับปรุงค่า Environment Variable ของเราโดยใช้แบบฟอร์ม

มาสร้างแบบฟอร์มพร้อมฟิลด์ข้อความแต่ละฟิลด์เพื่อเป็นตัวแทนของตัวแปรสภาพแวดล้อมในแอพของเราและตั้งค่า ID ฟิลด์ทั้งหมดเป็น ID ของตัวแปรสภาพแวดล้อม
