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

Hope this wins the race due to its performance and most important not a chained logic using .replace('&','&').replace('<','<')...

var mapObj = {
   '&':"&",
   '<':"<",
   '>':">",
   '"':""",
   '\'':"'"
};
var re = new RegExp(Object.keys(mapObj).join("|"),"gi");

function escapeHtml(str) 
{   
    return str.replace(re, function(matched)
    {
        return mapObj[matched.toLowerCase()];
    });
}

console.log('');
console.log(escapeHtml(''));
