json内容，该如何循环输出（JS）

Posted 2023-04-01

"c4":564,"c6":14,"c7":1,"c1":573
以上为JSON内容，输出为以下格式，这段JS该如何写？
localStorage[4]=564;
localStorage[6]=14;
localStorage[7]=1;
localStorage[1]=573;

思路

1、获取key值cxxx和对应的value值

2、去掉c，获取数值

3、根据key获取到的数值把对应的value值放入数组中(把字符串转换为整数，parseInt(value,进制);)

var str = "c4":564,"c6":14,"c7":1,"c1":573;
var localStorage=[];
for(var key in str)
   localStorage[parseInt(key.replace('c',''),10)]=parseInt(str[key],10);

参考技术A <script type="text/javascript">
var json="c4":564,"c6":14,"c7":1,"c1":573;
var localStorage=[];
for(var item in json)
localStorage[item.replace("c","")] = json[item];

alert(localStorage);
</script>

var json=eval(str);
json.c4 取值
