我将如何显示日期，我在一周中有最高值，但我需要将最大值与一周中的正确日期相匹配。如果您有想法，请使用jsfiddle或其他程序来显示！谢谢！

<script>
function total() {
	var th = Number(monday.value) + Number(tuesday.value) + Number(wednesday.value) + Number(thursday.value) + Number(friday.value) + Number(saturday.value) + Number(sunday.value);
	alert("You gamed for " + th + " hours this week");
var ah = th / 7;
alert("Your average is " + ah + " hours this week");
var arr = [Number(monday.value), Number(tuesday.value), Number(wednesday.value), Number(thursday.value), Number(friday.value), Number(saturday.value), Number(sunday.value)]
var hh = 0;
var max = arr[0];
for(var i = 1;i < arr.length;i++) {
	if(arr[i-1] < arr[i]) {
  	max = arr[i];
  }
}
alert("Maximum hours you have gamed in one day is " + max);
}

button.onclick = total;

试试这个 

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

你应该创建一个星期几的数组，如下所示：

var days = ['monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday', 'sunday']

然后在名为"arr"的数组中找到 indexOf max 数字，以查找星期几作为数字（从星期一开始）（当然，这是在代码中找到最大值之后）

var dayNumber = arr.indexOf(max);

然后通过 do 找到与该数字对应的星期几

var day = days[dayNumber]

希望这有帮助！

另外：找到最大值的更简单方法是使用内置的 Math.max 函数，如下所示

Math.max.apply(null, arr)
