如何在嵌套JSON中导航

json

我有嵌套的JSON对象，例如

{"baseball": 
            {"mlb": 
                   {"regular": 
                             {"_events": [{"start_time": "2011-07-31 17:35", "lines":
[{"comment": "", "coeff": "2.35", "title": "2", "old_coeff": "2.35", "is_main": true}, 
{"comment": "", "coeff": "1.59", "title": "2", "old_coeff": "1.59", "is_main": true}, 
{"comment": "", "coeff": "1.59", "title": "2", "old_coeff": "1.59", "is_main": true}, 
{"comment": "", "coeff": "2.35", "title": "2", "old_coeff": "2.35", "is_main": true}], 
"members": ["atlanta", "florida"]
                                 }
                                  ]
                                   }}}}

而且我需要获取_events数组并对其进行解析。但是我不知道_events之前的单元格中的内容以及它们的状态。如何使用这种结构？

function recursiveGetProperty(obj, lookup, callback) {
    for (property in obj) {
        if (property == lookup) {
            callback(obj[property]);
        } else if (obj[property] instanceof Object) {
            recursiveGetProperty(obj[property], lookup, callback);
        }
    }
}

就像这样使用它：

recursiveGetProperty(yourObject, '_events', function(obj) {
    // do something with it.
});

这是一个有效的jsFiddle：http :

：它会输出到控制台，因此您需要Ctrl+Shift+J/
Cmnd+Option+I在chrome中或在Firefox中打开firebug，然后重新运行它）
