How to set custom tabindex in html

javascript tabindex focus
tab order html
tabindex not working
angular tabindex
tabindex accessibility
jquery set tabindex
html tabindex skip
html focusable

I have a dynamic html page, and I have an element (div.id=myComponent) in this html, that has three input element inside.

The direction of the body element is rtl and div.id="myComponent" element is ltr like this:

<html>
<body style="direction: rtl;">
    <input type="text" />  <!-- I can not set tabindex for this elements. beacuse these are generate the dynamically. -->
    ...
    <!-- any elements -->
    <div style="direction: ltr;" id="myComponent">
        <span> <input tabindex="3" type="text" placeholder="y" /></span>
        <span><input tabindex="2" type="text" placeholder="m" /></span>
        <span><input tabindex="1" type="text" placeholder="d" /></span>
    </div>
    <input type="text"  />
    ...
</body>

</html>

I need it, when the focus enters the div.id="myComponent", like below:

d => m => y

but is reverse.

I use the tabindex attribute, but it is not working correctly.

How do you fix this problem?

Thanks.

Remove direction from div.id="myComponent" setting multiple direction will cause problem or is confusing. Rearrange the #myComponent elements.

    <body style="direction: rtl;">
        <input type="text" />  <!-- I can not set tabindex for this elements. beacuse these are generate the dynamically. -->
        ...
        <!-- any elements -->
        <div id="myComponent" >
            <span><input type="text" placeholder="d" /></span>
            <span><input type="text" placeholder="m" /></span>
            <span><input type="text" placeholder="y" /></span>
        </div>
        <input type="text"  />
    </body>

Working example can be found at here

Update:

  1. To set ltr direction to elements inside #myComponent use following css property -

    #myComponent > *{ 
     direction: ltr 
    }  
    
  2. To preserve the element placing direction in 'ltr', wrap the span elements inside other div with property float:left. The updated example can be found at here

HTML Global tabindex Attribute, Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java� The tabindex attribute specifies the tab order of an element (when the "tab" button is used for navigating). The tabindex attribute can be used on any HTML element (it will validate on any HTML element. However, it is not necessarily useful).

You just simple to change your tabindex

    <html>
<body style="direction: rtl;">
    <input type="text" />  <!-- I can not set tabindex for this elements. beacuse these are generate the dynamically. -->
    ...
    <!-- any elements -->
    <div style="direction: ltr;" id="myComponent">
        <span> <input tabindex="1" type="text" placeholder="y" /></span>
        <span><input tabindex="2" type="text" placeholder="m" /></span>
        <span><input tabindex="3" type="text" placeholder="d" /></span>
    </div>
    <input type="text"  />
    ...
</body>

</html>

Please try to focus on your div first by JS script

document.getElementById("myComponent").focus();

And tabindex should work like you expect

tabindex, If you set the tabindex attribute on a <div> , then its child content cannot be scrolled with the arrow keys unless you set tabindex on the content,� Using tabindex, you can specify an explicit order for focusable page elements, insert an otherwise unfocusable element into the tab order, and remove elements from the tab order. For example:

Body tag have style direction: rtl and child #myComponent have too direction: rtl. That means reverse and again reverse - "ymd" (body) reverse to "dmy" and (#myComponent ) reverse to "ymd" which is first order. Need to chose which one have to used. Example with body style="direction: rtl; only :

<body style="direction: rtl;">
    <input type="text" />  <!-- I can not set tabindex for this elements. beacuse these are generate the dynamically. -->
      ...
    <!-- any elements -->
    <div id="myComponent">
        <span><input type="text" placeholder="y" /></span>
        <span><input type="text" placeholder="m" /></span>
       <span><input type="text" placeholder="d" /></span>
    </div>
    <input type="text"  />
      ...
</body>

Tab-indexes are not relevant to this problem - you can added if are needed.

How and when to use the tabindex attribute, When to use a tabindex value of zero For example, we may need to create a custom button element, which will not be focusable by default because it's not actually a <button> . We can add this functionality back with the tabindex attribute, and specify its focus order as any regular button element would have. After tabbing sequentially thru all the elements with positive tabindex values, tabbing will navigate thru the other focusable elements (links, form controls and objects) that have their tabindex set to zero (tabindex="0"), or no tabindex attribute set at all. tabindex="0" allows a non-form/link/object element to be placed in the default

A negative value (usually tabindex="-1") means that the element is not reachable via sequential keyboard navigation, but could be focused with Javascript or visually. It's mostly useful to create accessible widgets with JavaScript. You can observe the Tabindex Accessibility example below to clear confusion.

A negative value is useful when you have off-screen content that appears on a specific event. The user won't be able to focus any element with a negative tabindex using the keyboard, but a script can do so by calling the focus() method.

tabindex="0" means that the element should be focusable in sequential keyboard navigation, but its order is defined by the document's source order.

A positive value means the element should be focusable in sequential keyboard navigation, with its order defined by the value of the number. That is, tabindex="4" is focused before tabindex="5", but after tabindex="3". If multiple elements share the same positive tabindex value, their order relative to each other follows their position in the document source. The maximum value for tabindex is 32767. If not specified, it takes the default value 0.

Comments
  • Is there any reason you cannot just reorder the elements in the HTML for myComponent rather than use the tabindex attribute? Use of the tabindex attribute is considered a bit of an anti-pattern.
  • the myComponent has been used in many place. in that case, I should reorder the elements in the all of documents.

  • Body tag have style direction: rtl and child #myComponent have direction: ltr, Please read the question more carefully.
  • I'm sorry if I wasted time, but that creates the needed order "d => m => y". You can see this. I'll see how this happens, because it confused me.
