如何从javascript中的对象检索特定的字段?
问题描述:
我想要检索JavaScript对象的一部分。如何从javascript中的对象检索特定的字段?
最终的对象应该具有的所有hits.hits._source 我尝试不同的事情lodash或下划线,但我没有得到它
我inital对象是
{
"took": 7,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 3,
"max_score": 1,
"hits": [
{
"_index": "users",
"_type": "user",
"_id": "1",
"_score": 1,
"_source": {
"id": "112",
"type": "pro",
"email": "[email protected]"
}
},
{
"_index": "users",
"_type": "user",
"_id": "2",
"_score": 1,
"_source": {
"id": "2",
"type": "pro",
"email": "[email protected]"
}
}
]
}
}
我想获得
[
{
"id": "112",
"type": "pro",
"email": "[email protected]"
},
{
"id": "2",
"type": "pro",
"email": "[email protected]"
}
]

可以这样做:
var output=[];
var input=o.hits.hits;
for(i=0;i<input.length;i++)
output.push(input[i]._source);
console.log(output);
啃削从root.hits.hits “_source” – dandavis 2015-02-23 08:25:51
'B = [];对于(i的a.hits.hits){b.push(a.hits .hits [i] ._ source)}''会得到'b'作为你的答案 – itzMEonTV 2015-02-23 08:29:55
