Suggestion for fields — Automatically adding a TITLE ATRIBUTE based on MB ID

Well,

I just accomplished a satisfactory result injecting some custom jQuery on WordPress admin. Using the code below I can force the most common fields to have a TITLE attribute based on their IDs:

jQuery('input, textarea, select, .wp-color-picker').each(function(){
    jQuery(this).attr('title', jQuery(this).attr('id'));
});
jQuery('.rwmb-switch').each(function(){
    jQuery(this).next().attr('title', jQuery(this).attr('id'));
});
jQuery('label').each(function(){
    jQuery(this).attr('title', jQuery(this).attr('for'));
}); 

Hope to be useful to someone!

Hello, Long.

Yes yes, I understand perfectly, but I was talking about the attribute title IN A FIELD itself, not the general title of a array of fields — the whole metabox thing.

My suggestion:

<img id="my-id" src="xxx" alt="abc" TITLE="my-id" />
<input type="text" id="my-id2" size="30" TITLE="my-id2" />
<select id="my-id3" name="pick-a-boo" title="my-id3"> ... </select>

What we have today:

<img id="my-id" src="xxx" alt="abc" />
<input type="text" id="my-id2" size="30" />
<select id="my-id3" name="pick-a-boo"> ... </select>

It could be added on the metabox root code, however I can'r mess up the core code there, because it will me lost upon updating:

if ( class_exists( 'RWMB_Field' ) ) {
    class RWMB_Phone_Field extends RWMB_Field {
        public static function html( $meta, $field ) {
            return sprintf(
                '<input type="tel" name="%s" id="%s" value="%s" title="%s">',
                $field['field_name'],
                $field['id'],
                $meta,
                $field['id'] // <------- THIS
            );
        }
    }
}

Well, just and idea. I found a workaround using jQuery, but it would be great to have this implemented, at least on INPUT, SELECT, TEXTAREA.

Thank you!
