blocks|key|311777|text|如果输入json是稳定的，并且不需要控制任何边缘情况(任意深度，顶级类型不匹配，例如"key1":+"not+a+dict")，那么这就解决了您的问题：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|311778|ret+=+[]

<p>if your input json is stable and you do not need to control any edge cases (arbitrary depth, a top-level type mismatch, e.g. <code>"key1": "not a dict"</code>) then this solves your problem:</p>

<pre><code>ret = []
for k, v in js.items():
    if v.get("filterkey") == "filtervalue":
        ret.append(k)
</code></pre>

blocks|key|990387|text|在这个示例中，"key1“出现了几次，但看起来您需要最外层的键名。如果是这样的话，那么使用to_entries是一个很好的方法，例如：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|990388|to_entries[]
%7C+if+.value.filterkey+==+"filtervalue"+then+.key+else+empty+end|code-block|syntax|javascript|990389|或相当于：|990390|to_entries[]

%7C+.key|990391|entityMap^0|19|A|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|P|$]]

<p>In the example, "key1" appears several times, but it looks like you want the outermost key name.  If that's the case, then using <code>to_entries</code> is a good way to go, e.g.:</p>

<pre><code>to_entries[]
| if .value.filterkey == "filtervalue" then .key else empty end
</code></pre>

<p>Or equivalently:</p>

<pre><code>to_entries[]
| select(.value.filterkey == "filtervalue" )
| .key
</code></pre>


<p>I have a json file with key and the value is a json with key value pair. I would like to filter and extract the key based on the inner key value pair. Any help is greatly appreciated</p>

<p>Example json data:</p>

<pre><code>{
    "key1": {
      "filterkey": "filtervalue",
      "key1": "value1"
    },
    "key2": {
      "key1": "value1",
      "key2": "value2"
    }
}
</code></pre>

<ul>
<li>Filter: "filterkey": "filtervalue"</li>
<li>expected output: "key1"</li>
</ul>
