Keyboard KeyCode Tool - Online Get KeyCode and KeyAscii Values

Welcome to use our Keyboard KeyCode Tool! This tool provides developers with a convenient way to get the KeyCode and KeyAscii values of each keyboard key online. You can easily obtain the code values of keys and perform corresponding encoding conversions to enhance encoding efficiency.

Tool Features

  • KeyCode Query: With this tool, users can quickly query the KeyCode value for each keyboard key. Just press any key on the keyboard to get the corresponding KeyCode value.
  • KeyAscii Code Query: This tool not only supports obtaining KeyCode values but also extracts the Ascii code of each key. It is especially suitable for developers who need to handle keyboard input.
  • Letters and Special Characters Handling: If the key pressed is a letter, the KeyCode value equals the Ascii value of that uppercase letter; if it is another character, the KeyCode and the Ascii value of that key’s lower-case character will be the same.
  • Convenient Online Query: This tool requires no software installation, and can be used directly online, making it convenient for developers to quickly query key codes during programming, saving time.

How to Use the Keyboard KeyCode Tool?

Using this tool is very simple, just follow the steps below:

  1. Click or press any key on the keyboard on the tool page.
  2. The tool will automatically extract and display the KeyCode and Ascii code of that key.
  3. You can view the code values of each key to understand the encoding method of keyboard input, helping you with program development or debugging.

Example:


Input Key: A
KeyCode: 65
KeyAscii Code: 65
                

Input Key: 1
KeyCode: 49
KeyAscii Code: 49

Common Uses

  • Development and Debugging: The keyboard key code query tool can help developers quickly obtain the KeyCode and Ascii code of keys when handling keyboard input, facilitating debugging input events.
  • Form Input Validation: In forms or user input validation, ensure that the input characters comply with regulations; you can validate by checking the Ascii code of the keys.
  • Game Development: During the game development process, handling keyboard events is necessary, and this tool can easily determine the KeyCode corresponding to user input.
  • Keyboard Mapping: It can help developers map keyboard keys to different coded values according to actual needs, accommodating different systems or program designs.

Frequently Asked Questions

1. How to obtain the KeyCode and Ascii code for a specific key?

Just click the key or use the keyboard to input; the tool will automatically extract and display the corresponding KeyCode and Ascii code. No extra operations are needed, it's very convenient.

2. Why does the KeyCode of letters match their Ascii code?

For letter characters, the KeyCode value is the same as the Ascii code. Specifically, the uppercase letter’s Ascii code pressed is the KeyCode value. For example, the Ascii code for the letter "A" is 65, so the KeyCode is also 65.

3. How is the KeyCode determined if the key is a special character?

For special characters, the KeyCode value will be determined based on the Ascii code of that character's lower-case letter or symbol. For instance, the Ascii code for the number key "1" is 49, and its KeyCode is also 49.

Summary

Using the Keyboard KeyCode Tool, developers can quickly query and extract the KeyCode and Ascii code of keyboard keys. Whether handling keyboard events or developing games, applications, etc., this tool can provide precise key code support to enhance development efficiency.
