需求：根据一段字符串，将checkbox反显，通常用在修改中。
<html>
<head>
<script type="text/javascript" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".btn1").click(function(){
var tt = "Bike,Airplane";
var array = tt.split(",");
$("input[name=‘vehicle‘]").each(function(){ //遍历checkbox
for(var i=0;i<array.length;i++){
if($(this).val()==array[i]){ //将checkbox的value与字符数组逐一比较
$(this).attr("checked","checked");
}
}
});
});
});
</script>
</head>
<body>
<form action="">
I have a bike:
<input type="checkbox" name="vehicle" value="Bike" />
<br />
I have a car:
<input type="checkbox" name="vehicle" value="Car" />
<br />
I have an airplane:
<input type="checkbox" name="vehicle" value="Airplane" />
</form>
<button class="btn1">Hide Checkboxes</button>
</body>
</html>
