<input hidden id="cityCode" name="cityCode" value="${city}">

This is an HTML input element with three attributes:
1. "hidden" - This attribute indicates that the input element should be hidden from the user interface.
2. "id" - This attribute provides a unique identifier for the input element. In this case, the identifier is "cityCode".
3. "name" - This attribute specifies the name of the input element, which is "cityCode".
The value of the input element is set using the ${city} variable, which is likely populated elsewhere in the code. This input element is likely used to pass the city code value to the server when the form is submitted.

解释一下这段代码<input hidden id="cityCode" name="cityCode" value="${city}">
这段代码是一个HTML标签,其中包含一个隐藏的input元素。它有三个属性:id、name和value。
- id属性定义该元素的唯一标识符,可以在JavaScript中使用document.getElementById()方法获取该元素的引用。
- name属性定义该元素的名称,在提交表单时可以使用该名称来获取该元素的值。
- value属性定义该元素的值,它的值是从一个变量${city}中获取的,这个变量可能是在服务器端生成的,它的值将被提交到服务器端。
