First of all, thank you @jdkleo for your valuable suggestions!
To be honest, if you don’t scold me for playing Tetris, long live it. It’s not completely finished yet, it’s only 50% complete, and there are still a lot of bugs.
Functions that can be implemented:
1. Drop blocks
2. Randomly generate new blocks
3. Block movement.
There are still a lot of bugs at the moment. Since this is my first time writing such a "big" game with more than 1,000 lines of code, I'm asking for advice from experts. There are too many bugs.
Press START to start the game.
Please give me some suggestions. This is my first time writing a JS game.
I referred to other people's codes on the Internet, but I didn't copy them.
The code can be run directly without referencing JQUERY.
I hope the experts can give me some advice! ! ! ! Not very grateful! ! !

Ver 0.2 has been released (2014-12-26), the latest code:
Things revised this time:
1. The left and right sides can be moved.
2.Can rotate
3. A full row of blocks can be eliminated.

Code:
