具有两个同名的输入元素是否有效？ [英] Is it valid to have two input elements with the same name?

问题描述

即：

 <表格1> 
< input type =hiddenname =urlvalue =1> 
< / form 1> 
  

和

 <表格2> 
< input type =hiddenname =urlvalue =2> 
< / form 2> 
  

这是否允许且有效？

解决方案

是，有效

这是好的

 < form name =form1> 
< input type =hiddenname =urlvalue =1> 
< / form> 
 
< form name =form2> 
< input type =hiddenname =urlvalue =2> 
< / form> 
  

这也很好，通常会被解释为一个值数组，例如 {url：[1，2]} ，具体取决于您的服务器的功能。在URL编码中，它看起来像 url = 1& url = 2 。

 < form name =form1> 
< input type =hiddenname =urlvalue =1> 
< input type =hiddenname =urlvalue =2> 
< / form> 
  

i.e.:

<form 1>
<input type="hidden" name="url" value="1">
</form 1>

and

<form 2>
<input type="hidden" name="url" value="2">
</form 2>

Is this allowed and valid?

解决方案

Yes, it is valid

This is Good

<form name="form1">
  <input type="hidden" name="url" value="1">
</form>

<form name="form2">
  <input type="hidden" name="url" value="2">
</form>

This is also fine and will generally be interpreted as an array of values, e.g. {url: [1, 2]}, depending on what your server does. In a URL encoding, it will look like url=1&url=2.

<form name="form1">
  <input type="hidden" name="url" value="1">
  <input type="hidden" name="url" value="2">
</form>
