How to Remove HTML Tags from Strings in JavaScript?

Stripping HTML Tags from Strings in JavaScript

Stripping HTML tags from a string is a common necessity in JavaScript. One approach involves employing regular expressions to match and remove tag structures.

Regex Approach

The following regular expression can be used to replace HTML tags with empty strings:

cleanText = strInputCode.replace(/<\/[^>]+(>|$)/g, "");

This regex targets HTML end tags (e.g.,

) and replaces them with empty strings. It also handles situations where end tags are missing or have incorrect formatting.

Examples

  • Input: '
    Hello
    '
  • Output: 'Hello'
  • Input: 'Unterminated Tag
  • Output: 'Unterminated Tag '

Limitations

While the regex is effective in most cases, it may struggle with certain HTML structures. For instance:

  • Input: 'If you are < 13 you cannot register'
  • Output: 'If you are '
  • Input: '
    Hello
    '
  • Output: ' 42">Hello'

Considerations

Regular expressions can only be used to remove basic HTML tags. For more complex HTML structures, consider using a dedicated HTML parser or a sanitization library like sanitize-html.
