Tabindex不适用于<a>HTML中的</a>字段集<a>内</a>的<a>标记</a>

Question

I have designed a HTML for with the tabindex set to the fieds. There are 3 fieldsets. The lower fieldset contains the submit tab with the proper tabindex specified. But the tab is not pointing to the tag. After fieldset2 it is moving directly to fieldset.

Please find the following code described:

<form action="#" method="post" id="registrationfrm">
            <fieldset id="personalinfo">
            <div class="fieldwrapper">
                <label for="register_firstname">first name</label> 
                <div class="inputwrapper">    
                    <input type="text" tabindex="201" value="" name="register_firstname" id="register_firstname">
                </div>
            </div>
            <div class="fieldwrapper">
                <label for="register_lastname">last name</label>
                <div class="inputwrapper">
                    <input type="text" tabindex="202" name="register_lastname" id="register_lastname">

        </fieldset>
            </form>

CSS

#registration .fieldwrapper {
display:inline;
float:left;
padding:0 3px;
}


.inputwrapper {
display:block;
font-size:12px;
padding-bottom:10px;
}


a#registration_submit {
-moz-background-clip:border;
-moz-background-inline-policy:continuous;
-moz-background-origin:padding;
background:transparent url(/images/global/CreateNewAccountSubmit.png) no-repeat scroll 0 0;
float:left;
height:21px;
position:relative;
text-indent:-9000px;
width:160px;
}

I would be very glad to have your sugestion.

Thanks, Nirmal

Answer 1

I tried your code, and it does give focus to the registration link. But the registration link isn't shown due to the text indentation being set to -9000px . In order to do so, you can use the focus pseudo class and remove the text indentation. Eg

a#registration_submit:focus {
    text-indent:0;
}

Keep in mind that this doesn't work in the older IE browsers. To fix that, you might have to resort to JavaScript.
