@wordpress/escape-html

Escape HTML utils.

Installation

Install the module

npm install @wordpress/escape-html

This package assumes that your code will run in an ES2015+ environment. If you’re using an environment that has limited or no support for such language features and APIs, you should include the polyfill shipped in @wordpress/babel-preset-default in your code.

API

escapeAmpersand

Returns a string with ampersands escaped. Note that this is an imperfect implementation, where only ampersands which do not appear as a pattern of named, decimal, or hexadecimal character references are escaped. Invalid named references (i.e. ambiguous ampersand) are still permitted.

Parameters

Note we also escape the greater than symbol, as this is used by wptexturize to
split HTML strings. This is a WordPress specific fix

Note that if a resolution for Trac#45387 comes to fruition, it is no longer
necessary for __unstableEscapeGreaterThan to be used.

See: https://core.trac.wordpress.org/ticket/45387

Parameters

  • value string: Attribute value.

Returns
