如何在星期日隐藏div（javascript上的开放时间）

var da = new Date();
document.getElementById("display").innerHTML = da.toDateString();

  var d = new Date();
    var n = d.getDay();

var z = document.getElementsByClassName("end")[0].innerText;
//var o = parseInt(x,10);
//var c = parseInt(z,10);

var startTime = Date.parseExact(x, "h:mm tt");
var endTime = Date.parseExact(z, "h:mm tt");

    $(".open").show();
    $(".closed").hide();
}
else if (d.getDay = 0){
       $(".closed").show();
    $(".open").hide();
}
else {  
    $(".closed").show();
    $(".open").hide();
}
