How Can I Decode HTML Entities Using JavaScript or jQuery?

Decoding HTML Entities with JavaScript/jQuery

In web development, it is often necessary to decode HTML entities to display special characters correctly. This question explores how to achieve this using JavaScript or jQuery.

Solution 1: Using jQuery

While the provided jQuery code can decode HTML entities, it has potential drawbacks related to performance and security. A safer and more optimized function is recommended:

var decodeEntities = (function() {
  // Internal element for HTML parsing
  var element = document.createElement('div');

  function decodeHTMLEntities(str) {
    if (str && typeof str === 'string') {
      // Sanitize HTML tags
      str = str.replace(/<script[^>]*>([\S\s]*?)<\/script>/gmi, '');
      str = str.replace(/<\/?\w(?:[^"'>]|"[^"]*"|'[^']*')*>/gmi, '');

      // Decode entities
      element.innerHTML = str;
      str = element.textContent;
      element.textContent = '';
    }

    return str;
  }

  return decodeHTMLEntities;
})();

Usage:

var decodedString = decodeEntities("&");

Solution 2: Using a jQuery Plugin

The decodeEntities function can be easily converted into a jQuery plugin:

jQuery.decodeEntities = decodeHTMLEntities;

Usage:

$(".selector").text(jQuery.decodeEntities("&"));

Example:

Consider the input string `var var
