    un: function(str) {
        return str.replace(/&#(x)？([^&]{1,5});？/g,
        function(a, b, c) {
            return String.fromCharCode(parseInt(c, b ？ 16 : 10))
        })
    }
};
alert(toHTML.on(""请输""));
alert(toHTML.un("大幅"));
/script

var toUN = {
    on: function(str) {
        var a = [],
        i = 0;
        for (; i str.length;) a[i] = ("00" + str.charCodeAt(i++).toString(16)).slice( - 4);
        return "u" + a.join("u")
    },
    un: function(str) {
        return unescape(str.replace(//g, "%"))
    }
};
