如何在TypeScript中将字符串中的__占位符替换为文本框？

Got it, let's figure out how to swap every __ placeholder in your string with an interactive text box. The approach depends a bit on what environment you're working in, so here are the most common solutions:

Frontend (JavaScript/HTML) #

If you're building a web page and want users to fill in the boxes directly in the browser, use JavaScript's replace() method with a global regex to target all instances of __:

// Your original string
const originalText = "How are __ doing today ?. I'm doing __.";

// Replace every __ with a styled text input
const textWithInputs = originalText.replace(/_+/g, '<input type="text" class="fill-in-box" placeholder="Type here..." />');

// Insert the result into your webpage
document.getElementById('content-area').innerHTML = textWithInputs;

You can add CSS to style the input boxes for better visibility:

.fill-in-box {
  border: none;
  border-bottom: 2px solid #2c3e50;
  padding: 2px 5px;
  margin: 0 3px;
  width: 120px;
}

Backend/Automation (Python) #

If you're generating content (like HTML or a document) server-side, use Python's regex module to do the replacement:

import re

original_str = "How are __ doing today ?. I'm doing __."
# Replace all __ with HTML input elements
output_str = re.sub(r'__', '<input type="text" class="fill-in-field" />', original_str)

# Print or save the result
print(output_str)

Notes for Other Tools #

If you're using a word processor (like Microsoft Word) or a markdown editor that supports rich content, you can use the Find and Replace feature:

• Search for __
• Replace with the text box control specific to your tool (in Word, this is under the "Developer" tab > "Text Box Content Control")

Hope these options work for you! If you need tweaks for a specific platform, just let me know.
