Change the page title if a data attribute is found

Question

I'm working on an userscript for a website. Would it be possible to change the title of the site if it finds a certain data attribute?

This is what I currently have:

if ($(document.attr('data-class="car"')) {
    $("title").text('*Car found!*');
}

Answer 1

I'm guessing that AJAX is involved, in which case you can use:

var titleCheckTimer = setInterval (checkAndChangeTitle, 333);

function checkAndChangeTitle () {
    if ($('[data-class="car"]').length) {
        document.title = "*Car found!*";

        clearInterval (titleCheckTimer);
    }
}

(This also works on static pages as well.)
