  }
function showPosition(position)
  {
     var latitude = position.coords.latitude;
     var longitude = position.coords.longitude;

那是因为您form不包含元素latitudeand longitude，而您定义的上述表单具有这些字段，但它们从未提交。

<form action="" method="post">
    <input type="hidden" name= "longitude" id="longitude"> <!-- I have added here-->
    <input type= "hidden" name ="latitude" id="latitude"> <!-- I have added here-->
    <input type="submit" name="ido" value="Click" /></td>
    </form>

如果您需要独立的表单 - 那么您应该考虑使用自定义提交方法并通过 ajax 提交。这将使您有机会解析所需的元素，然后提交数据。
