radio 写法:


$(function(){
  $("tbody>tr:odd").addClass("odd"); 
  $("tbody>tr:even").addClass("even"); 
  $('tbody>tr').click(function(){
    $(this).addClass('selected').siblings().removeClass('selected').end().find(':radio').attr('checked', true);
  });
// $('table :radio:checked').parent().parent().addClass('selected');
  $('table :radio:checked').parents("tr").addClass('selected');
//$('tbody>tr:has(:checked)').addClass('selected');

})


checkbox写法:


$(function(){
  $("tbody>tr:odd").addClass("odd");
  $("tbody>tr:even").addClass("even"); 
  $('tbody>tr').click(function(){
    if($(this).hasClass('selected')){
      $(this).removeClass('selected').find(':checkbox').attr('checked', false);
    }else{
      $(this).addClass('selected').find(':checkbox').attr('checked', true);
    }
  });
// $('table :checkbox:checked').parent().parent().addClass('selected');
  $('table :checkbox:checked').parents("tr").addClass('selected');
  //$('tbody>tr:has(:checked)').addClass('selected');
})
