Question

我有一个POST请求，它接收一个JSON字符串作为结果。字段，值或数组的深度是多少？这些都是未知的。所以，我需要遍历每个json值，它的索引和它的值，并根据它执行操作。

$.post(
    "test.php", 
    { action: 'someaction', param: '2' },
    function(data) {
      //now data is a json string
      $.each(data, function() {
       key = data.key; //i need to retrieve the key
       value = data.value; //i need to retrieve the value also

       //now below here, I want to perform action, based on the values i got as key and values
      }
    },
    "json"
);

如何将JSON的值分隔为key和value？

对不起，伙计们，但我自己解决了。请不要生我的气。（如果社区需要，我会删除该问题。）

$.post(
    "test.php", 
    { action: 'someaction', param: '2' },
    function(data) {
      //now data is a json string
      $.each(data, function(key,value) {
       alert(key+value);
       //now below here, I want to perform action, based on the values i got as key and values
      }
    },
    "json"
);

好吧，JSON被解析为JavaScript对象。您可以使用for...in遍历它们：

for(var key in data) {
    if(data.hasOwnProperty(key)) {
        var value = data[key];
    }
}
