通过HTML表单旋转的tabindex [英] Rotate tabindex through html form

问题描述

我有被用作开票接口，一个PHP生成的形式。用户通过形式由pressing 设置页工作的方式。我需要通过的形式，直到他们完成开票流程旋转Tab键。

I have a PHP-generated form that is used as an invoicing interface. Users work their way through the form by pressing tab. I need to rotate the tab key through the form until they finalize the invoicing process.

例如，用这种形式：

 <form>

 <input type = "text" name="a" tabindex=1>
 <input type = "text" name="b" tabindex=2>
 <input type = "text" name="c" tabindex=3>
 <input type = "text" name="d" tabindex=4>
 <input type = "text" name="e" tabindex=5> 
 <input type = "text" name="f" tabindex=6>
 <input type = "button" name="g" tabindex=7>

 <input type = "submit" name="h" tabindex=8>

 </form>

我需要的选项卡索引移动从1到7，然后标签应该将他们带回领域的。它需要旋转，我需要将光标移动到时候我preSS ESC小时。

I need to move the tab index from 1 to 7, and then tab should move them back to field a. It needs to rotate and I need to move cursor to h when I press ESC.

示例 -

Tab键移动从A-> B-> C-> D-> E-> F-> G-> A-> B光标 - > ......->先按g

ESC键只需将光标移动到h

我怎么能做到这一点的HTML或JavaScript？

How can I do this in HTML or javascript?

推荐答案

我使用的名称的ID来代替。猜猜这有助于：

I used id instead of names. Guess this helps:

 <form>
     <input type = "text" id="a" tabindex=1/>
     <input type = "text" id="b" tabindex=2/>
     <input type = "text" id="c" tabindex=3/>
     <input type = "text" id="d" tabindex=4/>
     <input type = "text" id="e" tabindex=5/> 
     <input type = "text" id="f" tabindex=6/>
     <input type = "button" id="g" value="next" tabindex=7/>
     <input type = "submit" id="h" value="ok" tabindex=8/>
 </form>
    <script type="text/javascript">
    $('input').keydown(function(event){
        if(event.keyCode == 9 && $(event.target).is('#g') ){
            $('#a').focus(); 
            event.preventDefault();
        }
        else if (event.keyCode == 27){
            $('#h').focus(); 
            event.preventDefault();
        }
    });
    </script>
