使用JSON,返回每个ID的投票数量

我在PHP中有一个API文件,它以JSON方式返回投票:

[{"10002" : "-1"},{"10003" : "2"}]

现在,我基本上需要能够在for循环中检查每个ID的投票,例如:

var parsed = JSON.parse(document.body.innerHTML); //[{"10002" : "-1"},{"10003" : "2"}] in string
for (i=0;i<parsed.length;i++) 
 {
     var toAlter = document.getElementById(parsed[i].something); //I need to retrieve the ID somehow
     toAlter.childNodes[2].innerHTML = parsed[i].something; //Need to retrieve the vote amount for the ID here
 }

尝试

var parsed = JSON.parse(document.body.innerHTML); //[{"10002" : "-1"},{"10003" : "2"}] in string
for (i=0;i<parsed.length;i++) {
    var obj = parsed[i];
    for(key in obj){
        if(obj.hasOwnProperty(key)){
            var toAlter = document.getElementById(key); //I need to retrieve the ID somehow
            toAlter.childNodes[2].innerHTML = obj[key]; //Need to retrieve the vote amount for the ID    here     
        }
    }
