请注意，我们刚刚开始HTML和CSS，所以很抱歉的基本问题。
我们必须为一个学校项目做一个网站，由我们选择主题或事情。我选择了我叔叔的金属加工店。我想实现一个营业时间表。我搜索了网络，发现我必须使用JavaScript来完成这个，我从来没有使用过。我尝试了一些东西，但它不起作用。
它应该获取当前日期，然后通过工作日ID获取<tr>，并添加一个CSS类以进行进一步的格式化。

    function weekday() {
        var d = new Date();
        
        if (d.getDay() = 0)     {
                            document.getElementById("Sunday").classList.add('OpeningDay');
                            }
        
        if (d.getDay() = 1)     {
                            document.getElementById("Monday").classList.add('OpeningDay');
                            }
        
        if (d.getDay() = 2)     {
                            document.getElementById("Tuesday").classList.add('OpeningDay');
                            }
        
        if (d.getDay() = 3)     {
                            document.getElementById("Wednesday").classList.add('OpeningDay');
                            }
        
        if (d.getDay() = 4)     {
                            document.getElementById("Thursday").classList.add('OpeningDay');
                            }
        
        if (d.getDay() = 5)     {
                            document.getElementById("Friday").classList.add('OpeningDay');
                            }
        
        if (d.getDay() = 6)     {
                            document.getElementById("Saturday").classList.add('OpeningDay');
                            }                   
                        }

我想我可以用CASE Of来实现，但正如我所说的，我从来没有使用过Javascript

css

If condition应该是布尔值，比如d.getDay（）== 0。你正在做的是一个赋值。
