基本变量有错误的变量

Question

我想我知道问题所在。 承诺进入后台，循环继续进行，但是我如何才能使此代码起作用？

对于每个vm.applicantsDetails，我需要检查customerNumbers var relatedCustomerNumbers = vm.applicantsDetails[i].RelatedCustomerNumbers的数组，对于每个relatedCustomerNumbers，我都需要发出REST请求

for (var i = 0; i < vm.applicantsDetails.length; i++) {
  var relatedCustomerNumbers = vm.applicantsDetails[i].RelatedCustomerNumbers;

  for (var j = 0; j < relatedCustomerNumbers.length; j++) {
    // get the customer number
    var customerNumber = relatedCustomerNumbers[j];
    
    // To here everything is fine
    
    service.getCustomerData(customerNumber).then(function(response) {

        // This prints always the vm.applicantsDetails.length - 1!!!
        console.log(i);
        
        // i is always 1 , which is the vm.applicantsDetails.length - 1
        var applicantType = null;
        switch (i) {
          case 0:
            applicantType = "primary";
            break;
          case 1:
            applicantType = "secondary";
            break;
        }
        console.log(applicantType); // Always secondary
      }
    }
}
