Question

我如何显示当天，我一周内的价值最高，但我需要将最高值与一周中正确的日期相匹配。如果您有任何想法请使用jsfiddle或其他程序来显示！谢谢！

＆＃13;

<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;
</script>

Answer 1

试试这个

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

Answer 2

<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];
var days = ["Monday","Tuesday",...];
var dayOfMax = 0;

for(var i = 1;i < arr.length;i++) {
	if(arr[i-1] < arr[i]) {
  	max = arr[i];
    dayOfMax = i; // why not just get the index
  }
}

alert("Maximum hours you have gamed in one day is " + max);
alert("The day when you have gamed the maximum is " + days[dayOfMax]);
// 0 for Monday, 1 for Tuesday, 2 for Wednesday, and so on
}





button.onclick = total;
</script>

Answer 3

您应该创建一周中的日期数组，如下所示：

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

然后找到indexOf数组yo中的最大数字yo，称为'arr'，以星期几的形式查找星期几（从星期一开始）（当然，在您的代码中找到最大值后，Thi）

var dayNumber = arr.indexOf(max);

然后通过

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，如此

Math.max.apply(null, arr)

如何显示星期几（我有最高价值）？
