问如何在DOM上加载google字体？

EN

// Check if a cookie exists suggesting fonts are cached
if (!fonts_are_cached) {
    // Don't slow down rendering
    $(window).load(function() {

        // Load in custom fonts
        $.ajax({
            url: 'https://fonts.googleapis.com/css?family=KoHo:400'
        });

        // Don't actually do anything with them, just request them so they are cached.
        // Set cookie indicating fonts are cached

    });
}
