JavaScript html entities

[siberia-man]

Last year my colleague asked me help to implement an insertion of html-entities. This task was interesting but the searching was attractive because there are many copies of the manual parsing of the datum list of entities - phpjs.org :: html_entity_decode. It is bombastic code, in our opinion is unreasonable - we was looking for the compact and easy code using internal features of browsers. We found the solution completely satisfying our requests - it is compact, easy and uses internal parsing algorithms of browsers.

var Entity = {
    encode: function(value)
    {
        var div = document.createElement('div');
        var text = document.createTextNode(value);
        div.appendChild(text);
        return div.innerHTML.replace(/"/g, '"').replace(/'/g, ''');
    }, 
    decode: function(value)
    {
        var textarea = document.createElement('textarea');
        textarea.innerHTML = value;
        return textarea.value;
    }
};

var original = '& is <ampersand>';
var encoded = Entity.encode(original);
var decoded = Entity.decode(encoded);

alert([original, encoded, decoded].join('\n'));
// will output
// & is <ampersand>
// &amp; is &lt;ampersand&gt;
// & is <ampersand>
