How can I loop an function changing the variable each time it loops until all variables are used?

I want to loop a function changing the variable each time it runs until all variables are used. Currently, I have this function duplicated 20+ times changing out the "sa_g_week" for each one.

    if (sa_g_week_24_7 !== "yes" && sa_g_week_24_7 !== "closed" &&
        sa_g_week_24_7 !== 'n/a') {
        if (hkg_time >= sa_g_week_start && hkg_time < sa_g_week_end) {
            if (hkg_time >= sa_g_week_soon && hkg_time < sa_g_week_end) {
                document.getElementById("sa_gdot").classList.add('close_soon');
                document.getElementById("sa2_gdot").classList.add('close_soon');
            } else {
                document.getElementById("sa_gdot").classList.add('open');
                document.getElementById("sa2_gdot").classList.add('open');
            }
        } else {
            document.getElementById("sa_gdot").classList.add('closed');
            document.getElementById("sa2_gdot").classList.add('closed');
        }
    }
    if (sa_g_week_24_7 == "yes") {
        document.getElementById("sa_gdot").classList.add('open');
        document.getElementById("sa2_gdot").classList.add('open');
    }
