Text to HTML

This lesson is part of Web Developer Tools · All levels

Summary

Text to HTML converts plain text into HTML pieces that are ready to be displayed, generally by wrapping paragraphs using the p tag and new line with br. Special characters such as <, >, and & must be evaporated so as not to be considered markup. The blank line is usually used as a paragraph separator. If the text is from the user, do not paste it raw into the innerHTML because of the risk of injection.

Key points

The normal text is broken down into paragraphs based on the blank lines
New line in paragraph can be converted to tag br
Characters <, >, and & must be escaped
Use textContent or escaping when displaying user input
HTML results should be checked to ensure that the paragraph structure is consistent.
