为什么有一个文本输入的FORM输入，而有两个文本INPUT的输入没有？ [英] Why does a FORM with one text INPUT submit on enter while one with two text INPUTs does not?

问题描述

但是一个至少包含两个INPUT的表单（包含至少两个INPUT没有隐藏）在按回车时不会提交。

（任何脚本都没有提交/按钮/输入[type = submit]里面）

查看这个 jsfidle 。这种行为有解释/标准吗？

 < form id =form1method =POST> 
< p>是否提交：< / p> 
< input type =textplaceholder =focus and press enter/> 
< / form> 
 
< form id =form2method =POST> 
< p>是否< strong>不&< / strong>提交：其中/ p为H. 
< input type =textplaceholder =does not submit/> 
< input type =textplaceholder =/> 
< / form> 
  

解决方案

此行为是在HTML 2.0规范中引入的。有关更多详情，请参阅以下文章：

表单提交和ENTER键？

当表单中只有一个单行文本输入字段时，
用户代理应接受该字段中的Enter作为提交
表单的请求

来源： W3C规范

I have just found out that a FORM containing only one INPUT (not hidden) will automatically submit when pressing Enter.

But a form containing at least two INPUTS (not hidden) will NOT submit when pressing enter.

(None of the scripts have a submit/button/input[type=submit] inside)

Take a look at this jsfidle. Is there an explanation/standard for this behavior?

<form id="form1" method="POST">
    <p>Does submit:</p>
    <input type="text" placeholder="focus and press enter"/>
</form>

<form id="form2" method="POST">
    <p>Does <strong>not</strong> submit:</p>
    <input type="text" placeholder="does not submit"/>
    <input type="text" placeholder=""/>
</form>

解决方案

This behaviour was introduced in the HTML 2.0 specification. See the following article for more details:

Form submission and the ENTER key?

When there is only one single-line text input field in a form, the user agent should accept Enter in that field as a request to submit the form
