tabindex attribute also specifies the exact tab order of elements. This is achieved when the value of the attribute is set to a positive number of 1 or higher.
Setting a tabindex="1" will bring keyboard focus to that element first. Then it cycles through the sequence of specified tabindex values (2, 3, etc.), before moving to default and tabindex="0" items.
It's important to note that when the tab order is set this way, it overrides the default order (which uses the HTML source). This may confuse users who are expecting to start navigation from the top of the page. This technique may be necessary in some circumstances, but in terms of accessibility, take care before applying it.
Here's an example:
<div tabindex="1">I get keyboard focus, and I get it first!</div>
<div tabindex="2">I get keyboard focus, and I get it second!</div>
input and submit input form controls to be the first two items in the tab order. Add a tabindex attribute set to "1" to the search input, and a tabindex attribute set to "2" to the submit input.
tabindex attribute to the search input tag.
testString: assert($('#search').attr('tabindex'), 'Your code should add a tabindex attribute to the search input tag.');
- text: Your code should add a tabindex attribute to the submit input tag.
testString: assert($('#submit').attr('tabindex'), 'Your code should add a tabindex attribute to the submit input tag.');
- text: Your code should set the tabindex attribute on the search input tag to a value of 1.
testString: assert($('#search').attr('tabindex') == '1', 'Your code should set the tabindex attribute on the search input tag to a value of 1.');
- text: Your code should set the tabindex attribute on the submit input tag to a value of 2.
testString: assert($('#submit').attr('tabindex') == '2', 'Your code should set the tabindex attribute on the submit input tag to a value of 2.');
