width:150px;
display:block;
}
.CheckBoxLabelClass:hover{text-decoration:underline;}
.LabelSelected{background:url("mytest/jQuery/Check.png") no-repeat;}
</style>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".CheckBoxClass").change(function(){
if($(this).is(":checked")){
$(this).next("label").addClass("LabelSelected");
}
else{
$(this).next("label").removeClass("LabelSelected");
}
});
})
</script>
</head>
<body>
<div>

</div>
</body>
</html>

<title>脚本之家</title>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script>

$("document").ready(function(){
$("#all").click(function(){
if(this.checked)
{
$("input[name='checkbox']").each(function(){this.checked=true;});
$("#btn1").attr("value","反选");
}
else
{
$("input[name='checkbox']").each(function(){this.checked=false;});
$("#btn1").attr("value","全选");
}
});
$("#btn1").click(function(){
$("[name='checkbox']").attr("checked",'true');
})
$("#cancel").click(function(){
$("[name='checkbox']").removeAttr("checked");
})
$("#jishu").click(function(){
$("[name='checkbox']:even").attr("checked",'true');

$(this).attr("checked",'true');
}
})
})
$("#get").click(function(){
var str="";
$("[name='checkbox'][checked]").each(function(){
str+=$(this).val()+"/r/n";
})
alert(str);
})
})
</script>
</head>
<body>
<form name="form1" method="post" action="">
<input type="checkbox" id="all" name="all">
<input type="button" id="btn1" value="全选">
<input type="button" id="cancel" value="取消全选">
