como usar o unescapeHTML no javascript es6

January 04, 2020

Unescapes escaped HTML characters.

Use String.prototype.replace() with a regex that matches the characters that need to be unescaped, using a callback function to replace each escaped character instance with its associated unescaped character using a dictionary (object).

const unescapeHTML = str =>
  str.replace(
    /&amp;|&lt;|&gt;|&#39;|&quot;/g,
    tag =>
      ({
        '&amp;': '&',
        '&lt;': '<',
        '&gt;': '>',
        '&#39;': "'",
        '&quot;': '"'
      }[tag] || tag)
  );

unescapeHTML('&lt;a href=&quot;#&quot;&gt;Me &amp; you&lt;/a&gt;'); // '<a href="#">Me & you</a>'
