我试图根据用户对用户选择和输入的选项的输入来实现它，突出显示适合输入的时间和日期的单元格。
现在，我正在尝试这样做，以便获取一周中某一天的选项文本，并使用该文本进行搜索 <td>具有该文本的类的元素，并将其设置为变量单元格。然后，我为包含与当时选项文本相同 id 的元素设置一个变量，然后获取该元素的父节点及其子元素。在 child 中，它搜索 <td>也在可变单元格中的元素。

最佳答案
获取 selectedTime ，然后获取所有 td's是 tr 的第一个 child , 匹配 textContent与 selectedTime。如果匹配，将样式应用于 time td然后得到 parentElement其中，获取其所有子项并匹配 className or textContent与 selectedDay .
function enterAppointments() {
/** Remove previously selected styles */
document.querySelectorAll('td[style]').forEach(td => td.style.color = '');
const selectedTime = document.querySelector('#thetime').value;
const selectedDay = document.querySelector('#dayweek').value;
const timeTds = document.querySelectorAll('td:first-child');
[...timeTds].forEach(td => {
if(td.textContent === selectedTime) {
td.style.color = "blue";
[...td.parentElement.children].forEach(td => {
if(td.className == selectedDay) {
td.style.color = "yellow";
}
});
}
});
