With jQuery 1.4.2 and many previous version it is possible to select inputs like this:
$(\'input[value=test]\')
But with 1.4.3 and higher t
By this code you can select/make checked the input (type radio) by value, which is the same like "for" param in his label.
jQuery('label').click(function() {
labelID = jQuery(this).attr('for'); //find item and save "for" value
jQuery('input[type=radio][value='+labelID+']').trigger('click') ; // find input with value and click
});
