基于Jquery的回车成tab焦点切换效果代码(Enter To Tab )

第一种方法：

$(document).ready(function () { 
$(':input:text:first').focus(); 
$(':input:enabled').addClass('enterIndex'); 
// get only input tags with class data-entry 
textboxes = $('.enterIndex'); 
// now we check to see which browser is being used 
if ($.browser.mozilla) { 
$(textboxes).bind('keypress', CheckForEnter); 
} else { 
$(textboxes).bind('keydown', CheckForEnter); 
} 
}); 
function CheckForEnter(event) { 
if (event.keyCode == 13 && $(this).attr('type') != 'button' && $(this).attr('type') != 'submit' && $(this).attr('type') != 'textarea' && $(this).attr('type') != 'reset') { 
var i = $('.enterIndex').index($(this)); 
var n = $('.enterIndex').length; 
if (i < n - 1) { 
if ($(this).attr('type') != 'radio') 
{ 
NextDOM($('.enterIndex'),i); 
} 
else { 
var last_radio = $('.enterIndex').index($('.enterIndex[type=radio][name=' + $(this).attr('name') + ']:last')); 
NextDOM($('.enterIndex'),last_radio); 
} 
} 
return false; 
} 
} 
function NextDOM(myjQueryObjects,counter) { 
if (myjQueryObjects.eq(counter+1)[0].disabled) { 
NextDOM(myjQueryObjects, counter + 1); 
} 
else { 
myjQueryObjects.eq(counter + 1).trigger('focus'); 
} 
}
