如何动态传递数据以选择列表？

将您的Javascript代码更改为此

var kunnr;$(document).ready(function () {    $('#NAME1').autocomplete({        source: function (request, response) { $.ajax({     url: "Form2",     method: 'POST',     data: {         term: $('#NAME1').val()     },     success: function (data) {         response(data);     } });        },        select: function (event, ui) { kunnr = ui.item.kunnr; $.ajax({     url: "Form3",     method: 'POST',     data: {         kunnr: kunnr     },     success: function (data) {         var selectData = JSON.parse(data);//use JSON.parse(), if the data is not already json formatted         $("#Subaccount").empty();         selectData.forEach(function (obj) {         //NOTE the Value and Text are what you assigned them when you fetched them  $('#Subaccount').append($('<option></option>').val(obj.Value).html(obj.Text));         });     } });        }    });});
