Pertanyaan yang Sering Diajukan
Why escape HTML?
Unescaped characters like < and > are interpreted as HTML tags. Without escaping, user-submitted text containing <script> tags can execute arbitrary JavaScript — a cross-site scripting (XSS) attack.
Which characters are escaped?
The five core HTML special characters: & → &, < → <, > → >, " → ", ' → '.
What is the difference between HTML escaping and URL encoding?
HTML escaping converts characters to HTML entities for safe rendering inside HTML. URL encoding converts characters to %XX hex format for safe use in URLs.
Should I escape or sanitize user content?
For displaying user content as plain text in HTML, escaping is sufficient. If you need to allow some HTML tags, use a trusted HTML sanitizer library.
Is HTML escaping enough to prevent XSS?
Escaping is the primary defense when inserting text into HTML content. However, the correct escaping strategy depends on context — JS strings, HTML attributes, and URLs each require different rules.
What does &amp; mean?
&amp; is a double-encoded ampersand — it renders as & in the browser. This usually occurs when content is escaped twice.
Is my data sent to a server?
No. All escaping and unescaping is performed in your browser using JavaScript string replacement.
Can I use this to prepare content for JSON inside HTML?
For JSON in HTML (e.g., inside a <script> tag), use JSON.stringify and ensure the string is placed correctly. HTML entity escaping alone is not sufficient.
