实现输入框用户输入时按指定词汇类型实时高亮格式化文本是否可行？

Absolutely—this kind of real-time, context-aware text formatting is completely achievable with standard development tools (whether you're building for the web, desktop, or mobile). Here's a quick breakdown of why it works and the core ideas that make this possible:

• Real-time input monitoring: You can listen for when the user types or edits text in the input field (using events like input in web dev, or equivalent in other frameworks). This lets you trigger your formatting logic instantly as the user types.
• Tokenizing the input: Split the user's text into individual words (tokens). For example, turning AB add medication aspirin into a list of separate words makes it easy to check each one against your predefined groups.
• Matching tokens to your predefined lists:
  • Any token in your attributes list (like "medication") gets your uppercase formatting.
  • Tokens that don't match any of your patients, attributes, or commands (like "aspirin") get wrapped in quotes.
  • Tokens from patients and commands can stay as-is (or you could add other formatting later if you want).
• Updating the display: Once you've applied the right formatting to each token, you can show the formatted text either in a separate display area (next to the plain input box, which avoids editing conflicts) or even modify the input field itself if that makes sense for your use case.

Your examples align perfectly with this approach:

Input: AB add medication aspirin → Formatted output: AB add MEDICATION "aspirin"
Input: JS get medication → Formatted output: JS get MEDICATION

This logic can also handle edge cases, like partial input (you could wait until the full word is typed before applying formatting, or show a partial highlight as the user types) or multiple matches in one input string.

You don't need any fancy, complex tools for this—basic JavaScript (for web) or similar logic in your framework of choice will cover all these steps. Since your predefined lists are small and the formatting rules are straightforward, the effort required is totally manageable.
