Notes

  • HTML escaping covers five characters: &, <, >, " and '. Everything else is output as is.
  • Escaping alone is not a complete security measure. The correct handling depends on where the text is inserted: HTML body, attribute, JavaScript or URL.
  • JS string escape is meant for embedding text in JavaScript string literals and is different from HTML entities.

Glossary

HTML escaping

Converting characters that have special meaning in HTML ("&", "<", ">", '"', and "'") into character references (such as &amp; or &lt;) so they display as literal text. It is also a common defense against XSS (cross-site scripting) when embedding user input into HTML.

JavaScript string escaping

Converting characters such as newlines, quotes, and backslashes into backslash-prefixed sequences (like \n or \") so they can safely appear inside a JavaScript string literal ('...' or "...").

FAQ

Why is HTML escaping necessary?

Characters such as "<" and "&" are interpreted as HTML. If user input is displayed without escaping, unintended tags can run, which leads to cross-site scripting (XSS).

Which characters are escaped?

Five characters are converted to their entities: ampersand (&), less-than (<), greater-than (>), double quote (") and single quote (').

When should I use JS string escape?

Use it to embed text in a JavaScript string literal. Line breaks and quotes are converted into backslash escape sequences.
