function unAllSelect(){
$("input[name='fruit']").removeAttr("checked");

$("#allBook").click(function(){
if(this.checked){//
$("input[name='book']").attr("checked", true);

</html>在实践中碰到一个问题——check全选失效。解决办法，使用prop方法代替attr。
$("input[name='book']").attr("checked", "checked");
$("input[name='book']").prop("checked", "checked");这或许是和jQuery版本有关。
