Decoding hex-containing escape sequences in JavaScript strings

rated 0 times [ 163] [ 5] / answers: 1 / hits: 42344 / 14 Years ago, wed, november 17, 2010, 12:00:00

I have a string in JS in this format:

httpx3ax2fx2fwww.url.com

How can I get the decoded string out of this? I tried unescape(), string.decode but it doesn't decode this. If I display that encoded string in the browser it looks fine (http://www.url.com), but I want to manipulate this string before displaying it.

Thanks.

You could write your own replacement method:

String.prototype.decodeEscapeSequence = function() {

    return this.replace(/\x([0-9A-Fa-f]{2})/g, function() {

        return String.fromCharCode(parseInt(arguments[1], 16));

    });

};
