Intermediate LevelHTML & Semantic Web
What is the difference between GET and POST form submission methods in HTML?
❓ Interview Prompt: Compare form method="GET" (URL query parameters, bookmarkable) vs method="POST" (request payload body, secure mutations).
1. Form 'method="GET"':
•
Appends form input data directly to the URL query string ('/search?query=html').
•
Idempotent: Best for search forms and data filtering.
•
Bookmarkable: URLs can be bookmarked and shared.
2. Form 'method="POST"':
•
Sends data in the HTTP request payload body.
•
Mutations: Used for state-changing operations (logging in, submitting orders).
•
Secrets: Never exposes passwords or credit card numbers in URL address bars!
Code Implementation Example
html
<!-- Search Form using GET method -->
<form action="/search" method="GET">
<input type="search" name="q" placeholder="Search...">
<button type="submit">Search</button>
</form>💡Search form using GET method to pass query parameters in URL.
🎯 Interview Key Takeaway
Use method="GET" for idempotent searches and data filtering; use method="POST" for state-changing form submissions.
