HTML表单：为什么行动无法获得价值？ [英] HTML Form: why action can't have get value in it?

问题描述

当我尝试以下结构时，它不会发送 id = value

 < form action =some.php？id = valuemethod =get> 
< input name =name1value =value1> 
< input type =submit> 
< / form> 
  

我知道我可以发送 id = value 在隐藏的领域，但它很有趣，为什么它不允许这样的结构？

解决方案

这是因为method = get 表单的部分意味着查询值必须来自表单值。

包含id = value的集合由包含表单值的集合覆盖。

这种行为似乎是嵌入到每个浏览器中的，所以我期望它是HTML规范的一部分。

更新

ahah：

之前已经询问过：
提交带有查询字符串参数的GET表单和隐藏的参数消失

要引用：

如规范（RFC1866，第46页; HTML 4.x第17.13.3节）所述：

如果方法是get，action是一个HTTP URI，用户代理接受action的值，附加一个'？'，然后附加表单数据集，使用application / x-www-form-urlencoded 内容类型。

When i try the following structure, it does't send id=value

<form action="some.php?id=value" method="get">
   <input name="name1" value="value1">
   <input type="submit">
</form>

I know that i can send id=value in hidden field, but it's interesting, why it doesn't allow such structure?

解决方案

It's because the "method=get" section of the form implies that the query values have to come from the form values.

The collection which contains "id=value" is overidden by the collection containing the form values.

This behaviour seems to be built into each browser, so I expect that it's part of the HTML specification.

Update

Ahah:

This has been asked before: submitting a GET form with query string params and hidden params disappear

To Quote:

As the specifications (RFC1866, page 46; HTML 4.x section 17.13.3) state:

If the method is "get" and the action is an HTTP URI, the user agent takes the value of action, appends a `?' to it, then appends the form data set, encoded using the "application/x-www-form-urlencoded" content type.
