如何用js（jQuery）动态输出json数据

var data=[{"keyid":"5","optype":"3","starttime":"2015-05-30 09:30:00","endtime":"2015-05-30 09:31:00","palletbarcode":"T00006","slocbarcode":"C00001","deviceno":"001","stateid":"1","autoid":"0","isplan":"F"},
{"keyid":"4","optype":"2","starttime":"2015-05-30 09:30:00","endtime":"2015-05-30 09:31:00","palletbarcode":"T00004","slocbarcode":"C00002","deviceno":"001","stateid":"1","autoid":"0","isplan":"T"},
{"keyid":"3","optype":"2","starttime":"2015-05-30 09:30:00","endtime":"2015-05-30 09:31:00","palletbarcode":"T00003","slocbarcode":"C00011","deviceno":"001","stateid":"1","autoid":"0","isplan":"T"},
{"keyid":"2","optype":"1","starttime":"2015-05-30 09:30:00","endtime":"2015-05-30 09:31:00","palletbarcode":"T00002","slocbarcode":"C00043","deviceno":"001","stateid":"1","autoid":"0","isplan":"T"},
{"keyid":"1","optype":"1","starttime":"2015-05-30 09:30:00","endtime":"2015-05-30 09:31:00","palletbarcode":"T00001","slocbarcode":"C00001","deviceno":"001","stateid":"1","autoid":"0","isplan":"F"}]
主键 keyid
操作类型 optype 1：上架2：下架3：移仓4：收货5：打托6：出货
开始时间 starttime
结束时间 endtime
托盘条码 palletbarcode
仓位条码1 flocbarcode
仓位条码2 slocbarcode
叉车代码 deviceno
状态 stateid 0未解析（未确认）1已解析（已确认）
自动标志 autoid 0：自动1：手工
是否计划内 isplan T:计划内；F:计划外
计划编号 plankeyid
在ul里面循环输出li，li显示的内容为9:30--09：31 托盘T0001从仓位C0001下架
计划内操作这种形式 有字符串有变量

写循环
<ul>
<script>
$().ready(function(){
for (var i = 0; i < data.length; i++) {
←←←←1←←←
if(data[i].optype=='2')｛

document.write("<li>"+data[i].palletbarcode+"</li>");←←←←2←←←
｝
}
});

</script>
</ul>
上面的代码能在ul内自动填充所有下架的托盘条码，并以li表现出来，如果你有别的需要显示出来，只需要在箭头2处添加不同的属性就可以，如果你还有别的条件筛选，只需要在箭头1处添加if块即可。

楼上的能实现 就是用循环 也可以用eval去做 个人觉得eval比较好点

我刚刚试了，没有问题啊 返回数据： weatherinfo: object radar: "jc_radar_az9010_jb" sd: "23%" wd: "北风" ws: "2级" wse: "2" city: "北京" cityid: "101010100" isradar: "1" njd: "暂无实况" qy: "1031" temp: "5" time: "12:35"
