I am trying to convert my integers back into string data so that I may target the appropriate members of the array. It works fine when I console log the data (console logs the appropriate message for the proper number of members of said array for each condition). But when I try to put the variable in the add/remove class method, it throws up an error saying unrecognized expression [object OBJECT]. Could someone please point me in the right direction?

我正在尝试将我的整数转换回字符串数据，以便我可以针对数组的适当成员。当我通过控制台记录数据时，它工作得很好(对于每个条件，控制台为适当数量的所述数组成员记录适当的消息)。但是，当我尝试将变量放入Add/Remove类方法中时，它抛出一个错误，说无法识别表达式[Object Object]。有谁能给我指个方向吗？

Ive attempted to convert the integers back to strings but it does not seem to work for the add/remove class method.

我尝试将整数转换回字符串，但它似乎不适用于Add/Remove类方法。

With this you are taking an integer and passing it to the jQuery constructor.
I assume you meant to concat it with a '#' in order to get a CSS selector for the id (see http://api.jquery.com/id-selector/). I don't know what you're trying to achieve with toString. You are converting the jQuery element which is pointing at the DOM element and throwing it away and replacing it with a String. A string is fine for logging, but no good for calling jQuery methods on.

这样，您将获取一个整数并将其传递给jQuery构造函数。我假设您打算将它与‘#’连接起来，以便获得id的css选择器(请参阅http://api.jquery.com/id-selector/).我不知道您试图使用toString来实现什么。您正在转换指向DOM元素的jQuery元素，并将其丢弃并替换为字符串。字符串适用于日志记录，但不适用于调用jQuery方法。

var color = $(hourArray[i]).toString();

Probably want:

可能想要：

var color = $('#' + hourArray[i]);
color.removeClass("row time-block")

You could also simplify this if you wanted by using a class on all your objects and going through them with each loop. Also, keep in mind that an ID that is just a number isn't considered valid if you're trying to meet HTML standards. if you want to store info on an element a custom data attribute might be your ideal solution.

如果需要，还可以通过在所有对象上使用一个类并在每个循环中遍历它们来简化这一过程。此外，请记住，如果您试图满足HTML标准，则只是一个数字的ID不会被视为有效。如果您希望存储有关元素的信息，则自定义数据属性可能是您理想的解决方案。

const hourArray = $('.hour');

hourArray.each(function (index) {
    var offset = index + 9; //this is only needed because you start at nine
    if (offset === hour) {
        $(this).removeClass("row time-block");
    } else if (offset < hour) {
        //offset will be your color
    } else {
        //else stuff 
    }
});
