Question

我编写的代码可以计算预订的价格。此代码适用于Chrome，Firefox，Edge ......但它在IE（10）中不起作用。它根本不会触发，因为即使是一开始就没有显示警报。我已经允许DirectX并且还将安全性设置为安全选项中可能的最低选项。我不知道这可能是什么原因。

要进行实时测试，请填写表单的第一页，在第二页上，一旦您选择到达日期和出发日期，就应该触发脚本：https://www.vakantiehuislesforges.com/reserveren-stap1/

这是触发它的事件：

<input type="text" name="aankomstdatum" id="aankomstdatum" onchange="aankomstdatumInput();berekenPrijs()">

这是JavaScript代码：

var aankomstDatumDate;
var vertrekDatumDate;
var spans;
var totaalPersonen;

alert("IE test");

//Get arrival date from datepicker + aantal kinderen & volwassenen
function aankomstdatumInput() {
var aankomstDatum = document.getElementById("aankomstdatum").value;
//alert(aankomstDatum);
document.getElementById("aankomst").innerHTML = aankomstDatum;
var parts = aankomstDatum.split('-');
aankomstDatumDate = new Date(parts[2],parts[1]-1,parts[0]);
//alert(aankomstDatumDate);
document.getElementById("aankomstDate").innerHTML = aankomstDatumDate;
//get aantal kinderen en volwassenen
spans = document.querySelectorAll('#aantallen span');
totaalPersonen = Array.from(spans).reduce((sum, spanElm) => sum + Number(spanElm.textContent), 0);
//alert(totaalPersonen);
}

//Get departure date from datepicker
function vertrekdatumInput() {
vertrekDatum = document.getElementById("vertrekdatum").value;
//alert(vertrekDatum);
document.getElementById("vertrek").innerHTML = vertrekDatum;
var parts2 = vertrekDatum.split('-');
vertrekDatumDate = new Date(parts2[2],parts2[1]-1,parts2[0]);
document.getElementById("vertrekDate").innerHTML = vertrekDatumDate;
}

//fire function onchange and get the arrival date and departure date and make the array
function berekenPrijs() {
//var aankomst = new Date("November 25, 2017");
//var vertrek = new Date("December 2, 2017");
//alert(aankomstDatumDate);
//alert(vertrekDatumDate);
//alert(aankomst);
var maand = aankomstDatumDate.getMonth();
var verblijfDagen = [];
var day = 1000*60*60*24;
var diff = (vertrekDatumDate.getTime()- aankomstDatumDate.getTime())/day;

//calculate all seperate days from arrival date to departure date and put them in an array   
for(var i=0;i<=diff; i++)
{
   var xx = aankomstDatumDate.getTime()+day*i;
   var yy = new Date(xx);
   var zz = (yy.getDate()+"-"+(yy.getMonth()+1)+"-"+yy.getFullYear());
   var parts = zz.split('-');
   var zzDate = new Date(parts[2],parts[1]-1,parts[0]);
   //check if this date is a saturday and in the correct Date structure && zzDate mag niet gelijk zijn aan vertrekdatum of laatst
   if(zzDate.getDay() === 0) verblijfDagen.push(zzDate);
   //alert(verblijfDagen);
}
//check if all the days are in the array
//alert (verblijfDagen);

感谢您的帮助！

我猜你的ECMA 6 arrow在IE10上不受支持，在这一行：

Array.from(spans).reduce((sum, spanElm) => sum + Number(spanElm.textContent), 0);

JavaScript代码在IE 10中不起作用
