以下实例综合讲解了几个选择器的使用，同时演示了使用jQuery实现隔行换色、荧光棒特效、复选框checkbox全选反选效果
<scripttype="text/javascript">
$(function(){
$("table tr:even").addClass("tdOdd");
$("th:first").css("background","#B4C6C1");//首个
$("table tr").mouseover(function(){
$(this).addClass("tdOver");}).mouseout(function(){
$(this).removeClass("tdOver");}).click(function(){//荧光棒
$(".tdClick").removeClass("tdClick");$(this).addClass("tdClick");
})//行锁定
$("input:checkbox:first").click(function(){
$("input:checkbox:not(input:checkbox:first)").each(function(){//剔除本身
$(this).attr( "checked",$("input:checkbox:first").attr("checked"));
})
})
$("input:checkbox:not(input:checkbox:first)").click(function(){
var flag=true;
$("input:checkbox:not(input:checkbox:first)").each(function(){
if(!this.checked){flag=false;}//不可使用if($(this).attr("checked","false")){flag=false;}
<p>
<brdata-filtered="filtered">
</p>
});
$("input:checkbox:first").attr("checked",flag);
})
});
