Javascript 表单结果是整数，而不是字符串值

我使用了这段代码并创建了数组：

对于（var i=0；i您是如何填充您的下拉列表的？我想它可能是这样的：

<select>
    <option value="1">Model 1<option>
    <option value="2">Model 2<option>
<select>


模式1
模式2

问题是，如果option标记的value属性中有一个整数，那么不管文本怎么说，都会得到这个整数。例如，这里如果我选择Model 2，表单的值仍然是2

这完全取决于您创建这些下拉列表的方式。
好吧，您正在将
i
作为第二个参数传递给
Option
（
新选项（json[car_make][i]，i）
），因此计数器的值将成为选项的值。如果您希望实际数组元素成为值，请将其传递：

new Option(json[car_make][i], json[car_make][i]);

或者，由于文本和值相同，只需省略第二个参数：

new Option(json[car_make][i]);

（对于
新选项（make，make）
也是如此，您只需使用
新选项（make）
）

如果
选项
元素没有明确的值，则其内部文本将成为值。
仅供参考，您的问题似乎与JSON无关。您命名为
JSON
的变量将对象作为值保存。JSON是一种数据交换格式，如XML、CSV或YAML。您需要显示下拉列表如何弹出的代码是的，这就是我怀疑的问题所在。@ptutt：它在代码示例的底部。谢谢Felix！就是它……duh；
