使用ko下拉列表绑定中的参数调用函数

Question

我想在knockout中绑定select标签的选项值，值   从ko viewmodel传入，输入参数依赖于   外循环。

它确实显示了populate droupdownlist

就像这个伪代码

 <-- ko for-each {data: travellerlist} -->

    <select data-bind =" foreach: GetYearList($data.passengerType())" >
       <option data-bind="value: key, text: value"></option>    <select>

 <--/ko-->

 function GetYear(passengerType) {

     $.ajax({
         url: baseUrl + 'JavascriptVariables/YearList',
         type: 'get',
         data: { passengerType: passengerType },
         success: function (data) {
             var yearList = [];
             if (data != null ) {
                 $.each(data, function (key, value) {
                     yearList.push(key, value);
                 });
                 debugger
                 return yearList;
            }
         },
         error: function (data) {
         }
     }); }
