Feature request: missing maxlength attribute support for <textarea>

[Massimo Lombardo]

Can you add support for the maxlength attribute when applied on textarea elements, please?

Current state of support: http://www.wufoo.com/html5/attributes/03-maxlength.html

Here's a shim I wrote (based on jQuery though)

if (!("maxLength" in document.createElement("textarea"))) {
    $("textarea[maxlength]").each(function () {
        var $this = $(this).on("keydown keyup focus blur", function (event) {
                var keyCode = event.which,
                    that = this;
                if (keyCode === 13 || keyCode >= 33) {
                    if (that.value.length >= limit) {
                        that.value = that.value.substr(0, limit - 1);
                        event.preventDefault();
                    }
                }
            }),
            limit = Math.abs(parseInt($this.attr("maxlength"), 10)) || -1;
    });
}

308 bytes once minified (according to Uglify.js)
