"circle": "2;3;4;5;6;1"
}
示例代码：

<style>
input{
appearance:none;
-moz-appearance:none; /* Firefox */
-webkit-appearance:none;
cursor: pointer;
margin:0;
}
input{
width:13px;
height:13px;
background: url(images/check.png);

}

}
</style>
</head>
<body>
<div class="modal-body form">
<div class="col-md-7 col-sm-7col-xs-7">
<input name="circle" type="checkbox" value="2" />周一
<input name="circle" type="checkbox" value="3" />周二
<input name="circle" type="checkbox" value="4" />周三

</body>
<script type="text/javascript">
$.ajax({
url: "data.json",
type: 'GET',
dataType: 'json',
success: function(data) {
$.each(data.circle.split(";"), function(i, item) {
$('input').attr('checked', 'checked')
})
}
});
</script>
</html>
2：当返回值是数组对象的时候
data.json:
{
"tasks": [{
"id": 1,
"name": "任务一"
}, {
"id": 2,
"name": "任务二"
},{
"id": 3,
"name": "任务三"
},{
"id": 4,
"name": "任务四"
}]
}
