循环json

可以写成：

var data=[{name:"a",age:12},{name:"b",age:11},{name:"c",age:13},{name:"d",age:14}]

for(var o in data){

alert(o)

alert(data[o])

alert("text:"+data[o].name+" value:"+data[o].age )

}

或是

<script type="text/javascript">

function text(){

var json = {"options":"[{/"text/":/"王家湾/",/"value/":/"9/"},{/"text/":/"李家湾/",/"value/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}

json = eval(json.options)

for(var i=0i<json.lengthi++)

{

alert(json[i].text+" " + json[i].value)

}

}

</script>

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)

}
