javascript - 如何根据选择选项访问变量的值？

Question

我有一个 SELECT 选项，根据所选值，我想更改变量 NumberHoliday 的值。

如何访问另一个函数中变量的值？

var NumberHoliday;
var finalTotal;

$(function() {
  $(document).on("change", "#deptType", function(e) {
      var totalValue = $('#deptType').val();

      if(totalValue == "Fraud"){
         NumberWeekValueFraud();

      }else{
       NumberWeekValueOther();
      }

  });
});

function NumberWeekValueFraud(){
  var NumberHoliday = 25.00;
  $('#totalDays2').val(NumberHoliday);
  return NumberHoliday;
}

function NumberWeekValueOther(){
  var NumberHoliday = 50.00;
  $('#totalDays2').val(NumberHoliday);
  return NumberHoliday;
}

function CountTotal(el){
   if(el.checked) {
       //use NumberHoliday here once checkbox is check,  depending on the select option value
}

Answer 1

可以将函数传递给函数

function CountTotal(el, fnValue){
   if (el.checked) {
   // do stuff with `fnValue`
   }
}

CountTotal(/* el */, NumberWeekValueFraud());

CountTotal(/* el */, NumberWeekValueOther());
