问题描述

我有嵌套的JSON对象,如

I have nested JSON object like

{"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"]
                                 }
                                  ]
                                   }}}}

我需要获取_events数组并解析它。但我不知道_events之前会在细胞中发生什么,以及它们将如何发展。我如何使用这种结构?

And i need get _events array and parse it too. But I don't know what will be in cells before _events and how they will. How do I work with this structure?

推荐答案

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);
        }
    }
}

只需像这样使用它:

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

这是一个有效的jsFiddle:( note :它输出到控制台,所以你需要 / 在Chrome中或在Firefox中打开firebug,然后重新运行它)

Here's a working jsFiddle: http://jsfiddle.net/ErHng/ (note: it outputs to the console, so you need to / in chrome or open firebug in Firefox and then re-run it)
