ADA compliance problem with Jtransform plugin
Hi ,
I am using the jquery transform , for a custom drop down box. I have added keyboard navigation , to the drop down box. I still need to make it ADA compliant. It doesnt read the names of the state when i navigate using keyboard. I dont get consistent results. I have included the code below ----------- any thoughts ??
jtransform code
(function($){
$(function(){
$('form').jqTransform();
});
/* Label Code */
var jqTransformGetLabel = function(){};
/* Hide all open selects */
var jqTransformHideSelect = function(oTarget){
var ulVisible = $('.jqTransformSelectWrapper ul:visible');
ulVisible.each(function(){
var oSelect = $(this).parents(".jqTransformSelectWrapper:first").find("select").get(0);
//do not hide if click on the label object associated to the select
if( !(oTarget && oSelect.oLabel && oSelect.oLabel.get(0) == oTarget.get(0)) ){$(this).hide();}
});
};
/* Select Code */
$.fn.jqTransSelect = function(){
return this.each(function(index){
var $select = $(this);
if($select.hasClass('jqTransformHidden')) {return;}
if($select.attr('multiple')) {return;}
var oLabel = jqTransformGetLabel($select);
/* First thing we do is Wrap it */
var $wrapper = $select
.addClass('jqTransformHidden')
.wrap('<div class="jqTransformSelectWrapper" tabindex="1"></div>')
.parent()
.css({zIndex: 10-index})
;
/* Now add the html for the select */
$wrapper.prepend('<div><span></span><a href="#" class="jqTransformSelectOpen"></a></div><ul role="menu"></ul>');
var $ul = $('ul', $wrapper).css('width',$select.width()).hide();
/* Now we add the options */
$('option', this).each(function(i){
var oLi = $('<li role="menuitem"><a href="#" index="'+ i +'">'+ $(this).html() +'</a></li>');
$ul.append(oLi);
});
/* Add click handler to the a */
$ul.find('a').click(function(){
$('a.selected', $wrapper).removeClass('selected');
$(this).addClass('selected');
//$(this).focus();
/* Fire the onchange event */
if ($select[0].selectedIndex != $(this).attr('index') && $select[0].onchange) { $select[0].selectedIndex = $(this).attr('index'); $select[0].onchange(); }
$select[0].selectedIndex = $(this).attr('index');
$('span:eq(0)', $wrapper).html($(this).html());
$ul.hide();
return false;
});
/* Set the default */
$('a:eq('+ this.selectedIndex +')', $ul).click();
$('span:first', $wrapper).click(function(){$("a.jqTransformSelectOpen",$wrapper).trigger('click');});
oLabel && oLabel.click(function(){$("a.jqTransformSelectOpen",$wrapper).trigger('click');});
this.oLabel = oLabel;
/* Apply the click handler to the Open */
var oLinkOpen = $('a.jqTransformSelectOpen', $wrapper)
.click(function(){
//Check if box is already open to still allow toggle, but close all other selects
if( $ul.css('display') == 'none' ) {jqTransformHideSelect();}
if($select.attr('disabled')){return false;}
$ul.slideToggle('fast', function(){
// var offSet = ($('a.selected', $ul));
//$ul.animate({scrollTop: offSet});
});
return false;
});
// Calculate the height if necessary, less elements that the default height
//show the ul to calculate the block, if ul is not displayed li height value is 0
$ul.css({display:'block',visibility:'hidden'});
var iSelectHeight = ($('li',$ul).length)*($('li:first',$ul).height());//+1 else bug ff
(iSelectHeight < $ul.height()) && $ul.css({height:iSelectHeight,'overflow':'hidden'});//hidden else bug with ff
$ul.css({display:'none',visibility:'visible'});
});
};
$.fn.jqTransform = function(){
return this.each(function(){
var selfForm = $(this);
if(selfForm.hasClass('jqtransformdone')) {return;}
selfForm.addClass('jqtransformdone');
if( $('select', this).jqTransSelect().length > 0 ){}
selfForm.bind('reset',function(){var action = function(){jqTransformReset(this);}; window.setTimeout(action, 10);});
});
};
})(jQuery);
$(document).ready(function() {
$('.jqTransformSelectWrapper').keypress(
function(event){
var code=event.keyCode;
var currentitem=$('.jqTransformSelectWrapper a.selected').attr('index');
//////Down arrow
if(code.toString() == 40){
currentitem=eval(currentitem)+1;
$('a:eq('+currentitem +')','ul').trigger('click');
}
//////Up arrow
if(code.toString() == 38){

$('a:eq('+currentitem +')','ul').trigger('click');
