求助json转为数组，并根据ID获得数组中值

Question

var json=[{name:"张三",age:25,sex:"男"},{name:"李四",age:35,sex:"男"},{name:"王五",age:45,sex:"女"}] 
function jsonToArray(){
   //这里要写个函数
}
想通过jsonToArray转化为以下格式：//初始化演示数据
personObj1=new Object()
personObj1.name="张三";
personObj1.sex="男";
personObj1.age=34;
personObj2=new Object()
personObj2.name="李四";
personObj2.sex="女";
personObj2.age=50; var psnArray = new Array();
psnArray[0] = personObj1;
psnArray[1] = personObj2;

Answer 1

var json='[{name:"张三",age:25,sex:"男"},{name:"李四",age:35,sex:"男"},{name:"王五",age:45,sex:"女"}]';
function jsonToArray(str){
    var reg=/\{.*?\}/g;
str=str.match(reg);
var arr=[];
for(var i in str){
arr.push(eval("("+str[i]+")"));
}
return arr;
}
var arr=jsonToArray(json);
for(var i in arr){
document.write(arr[i].name+":"+arr[i].age+":"+arr[i].sex+"<br/>");
}
这样？

Answer 2

还需要个key，如果我想提取json中name为"张三"的数据，只将这一部分转换为数组呢？

Answer 3

<script type="text/javascript">
    var on=[{name:"张三",age:25,sex:"男"},{name:"李四",age:35,sex:"男"},{name:"王五",age:45,sex:"女"}];
    function jsonToArray(){
        var l=on.length;
        var psnArray = new Array();
        for(var i=0;i<l;i++){
            window["personObj"+(i+1)]=new Object();
            window["personObj"+(i+1)].name=on[i].name;
            window["personObj"+(i+1)].sex=on[i].sex;
            window["personObj"+(i+1)].age=on[i].age;
            psnArray[i]=window["personObj"+(i+1)];
        }
    }
</script>

Answer 4

可以的<script type="text/javascript">
    var tt=new Object();
        tt.b1=1;
        tt.b2=2;
        tt.b3=3;
        tt.b4=4;
    var i=3;
    alert(tt["b"+i]);
</script>

Answer 5

var on=[{name:"张三",age:25,sex:"男"},{name:"李四",age:35,sex:"男"},{name:"王五",age:45,sex:"女"}]
    function jsonToArray(str){
        var l=str.length;
        var psnArray = new Array();
        for(var i=0;i<l;i++){
            window["personObj"+(i+1)]=new Object();
            for(var key in str[i]){
                window["personObj"+(i+1)].key+"="+str[i][key];
             }         
            psnArray[i]=window["personObj"+(i+1)];
        }
        alert (psnArray[2].age);
    }
    jsonToArray(on);我这样写出来就是动态获取key，但是获得的是undefined

Answer 6

var json='[{name:"张三",age:25,sex:"男"},{name:"李四",age:35,sex:"男"},{name:"王五",age:45,sex:"女"}]';
function jsonToArray(str){
    var reg=/\{.*?\}/g;
str=str.match(reg);
var arr=[];
for(var i in str){
arr.push(eval("("+str[i]+")"));
}
return arr;
}
var arr=jsonToArray(json);
for(var i in arr){
for(var j in arr[i]){
document.write(i+":"+j+"="+arr[i][j]+"<br/>");
}
}
j是你要的key吗？

Answer 7

就差一点点了：
    var on=[{name:"张三",age:25,sex:"男"},{name:"李四",age:35,sex:"男"},{name:"王五",age:45,sex:"女"}]
    function jsonToArray(str){
        var l=str.length;
        var psnArray = new Array();
        for(var i=0;i<l;i++){
            window["personObj"+(i+1)]=new Object();
            for(var key in str[i]){
                window["personObj"+(i+1)][key]=str[i][key];
            }
            psnArray[i]=window["personObj"+(i+1)];
        }
        alert (psnArray[2].age);
    }
    jsonToArray(on);

Answer 8

谢谢楼上的
还有个大问题看下面的jsonvar str=[
{id:"1",name:"张三",age:12},
{id:"2",name:"李四",age:34},
{id:"3",name:"王五",age:38},
{id:"4",name:"赵六",age:40},
{id:"5",name:"使命召唤",age:20},
{id:"6",name:"黑色行动",age:32}
];
根据str的信息制作了一个表格，每条信息前有个input[type=checkbox],我想提取选中状态中的json，并生成数组，并且我想随意调取选中状态中的name、age

Answer 9

这里的windown是什么意思呀
