选择框值作为 ID 而不是数据

Question

我有一个包含 3 个表 country 、 state 和 city 的数据库，工作正常。

问题是我有一个表单，我可以在其中毫无问题地选择这三个，但是在选择并将所选值存储在 DB 中之后，它存储数字 ID 而不是这三个的名称

select的php部分：

<div class="section colm colm6">
<label class="field prepend-icon select">
<select name="country" class="countries" id="countryId">
<option value="">Select Country</option>
</select>
<span class="field-icon"><i class="fa fa-globe"></i></span> 
<i class="arrow double"></i>                             
</label>
</div>

JS部分：

    function ajaxCall() {
        this.send = function(data, url, method, success, type) {
          type = type||'json';
          var successRes = function(data) {
              success(data);
          };

          var errorRes = function(e) {
              console.log(e);
              alert("Error found \nError Code: "+e.status+" \nError Message: "+e.statusText);
          };
            $.ajax({
                url: url,
                type: method,
                data: data,
                success: successRes,
                error: errorRes,
                dataType: type,
                timeout: 60000
            });

          }

        }

function locationInfo() {
    var rootUrl = "../api.php";
    var call = new ajaxCall();
    this.getCities = function(id) {
        $(".cities option:gt(0)").remove();

            $('.cities').find("option:eq(0)").html("Select City");
            if(data.tp == 1){

                    option.attr('value', key).text(val);
                    $('.cities').append(option);
                });
                $(".cities").prop("disabled",false);
            }
            else{
                 alert(data.msg);
            }
        });
    };

    this.getStates = function(id) {

            }

我做了更多的更改，并制作了以下代码，最终对我有用

    function ajaxCall() {
        this.send = function(data, url, method, success, type) {

如果你想要这个名字，你应该改变你的选项 attr 行：

option.attr('value', val).text(val);

Answer 3

你用什么来存储在数据库中。??以上代码仅用于绑定。 检查您是否正在保存文本或值？？

您提供的绑定代码看起来是正确的。
