HTML5 canvas online paint drawing tool (I) function Introduction

This is the first program I wrote with Javascript. It took a lot of detours in the writing process. So I want to share it after writing it and give it to beginners like me as a reference for learning, at the same time, I encountered some problems when writing this program. Here I will also discuss it with you, so that we can all make progress. Because it is a beginner in javascript, the level is low. You are welcome to raise comments.

The program contains the following content: 1. tool bar 2. Basic Drawing commands. Currently, only straight lines, rectangles, and circles are available. Some commands will be added later. 3. Linear Selection

4. select color 5. Save the Theme 6. Open the graph.

The following is my son's work. I 'd like to thank you!
