HtmlSpecialChars equivalent in Javascript?

Question

Apparently, this is harder to find than I thought it would be. And it even is so simple...

Is there a function equivalent to PHP\'s htmlspecialchars built into Javas

Answer 1

Here's a function to escape HTML:

function escapeHtml(str)
{
    var map =
    {
        '&': '&',
        '<': '<',
        '>': '>',
        '"': '"',
        "'": '''
    };
    return str.replace(/[&<>"']/g, function(m) {return map[m];});
}

And to decode:

function decodeHtml(str)
{
    var map =
    {
        '&': '&',
        '<': '<',
        '>': '>',
        '"': '"',
        ''': "'"
    };
    return str.replace(/&|<|>|"|'/g, function(m) {return map[m];});
}
