Jerry has been in touch with SAP UI5 since joining the CRM Fiori development team of SAP Chengdu Research Institute in 2014. He has published many articles on the working principle and source code analysis of SAP UI5 in the SAP community and the WeChat public account "Wang Zixi".

In Jerry's article for newbies who know nothing about SAP UI5, which materials are better to start with? once mentioned that Jerry has come all the way from SAP UI5 rookie, and knows that it is not easy for developers with only ABAP development background to transform to the SAP UI5 development field, so I designed this study for SAP UI5 beginners in my spare time. The tutorial divides the process of developing a complete SAP UI5 application into several steps, and strives to cover all the knowledge points involved in each step. These knowledge points may not be as in-depth as my UI5 source code analysis series articles, but strive to be easy to understand and easy for SAP UI5 beginners to understand.

The source code of each step of this tutorial is stored in my Github , identified by folders 01, 02, 03, etc. respectively.

Each step builds on the previous step with several new features added. It is recommended for beginners with zero foundation or little knowledge of SAP UI5 to learn step by step from the first step in order, download these codes to the local, cooperate with the text explanation of the tutorial, and do it yourself to deepen your understanding.

If you have any questions about each step of the tutorial, you are welcome to comment and leave a message in the article corresponding to the steps of the tutorial.

In the previous series of steps in this tutorial, we have more or less used Chrome developer tools to learn the development of SAP UI5 applications, such as viewing the controls defined in the SAP UI5 XML view through the Elements tab, and the native HTML code generated at runtime. , or in the Console tab, view the INFO or ERROR message when SAP UI5 is running in debug mode.

In the next series of steps starting from this step, let's systematically learn how to use Chrome developer tools to help us better develop SAP UI5.

This step focuses on how to use the Elements panel in Chrome developer tools to dynamically modify the standard css classes of SAP UI5 controls:
