我有一个json文件，如下所示
[{
"data": {
"aggregations": {
"openissue": {
"buckets": [{
"doc_count": 5,
"date": "25 aug"
},
{
"doc_count": 6,
"date": "26 aug"
},
{
"doc_count": 7,
"date": "27 aug"
},
{
"doc_count": 8,
"date": "28 aug"
}
]
}
}
},
"a": "not needed",
"b": "not needed"
},
{
"data": {
"aggregations": {
"closeissue": {
"buckets": [{
"doc_count": 9,
"date": "29 aug"
},
{
"doc_count": 10,
"date": "30 aug"
},
{
"doc_count": 11,
"date": "31 aug"
},
{
"doc_count": 12,
"date": "1 sept"
}
]
}
}
},
"a": "not needed",
"b": "not needed"
}, {
"data": {
"aggregations": {
"pendingissue": {
"buckets": [{
"doc_count": 13,
"date": "10 sept"
},
{
"doc_count": 14,
"date": "13 sept"
},
{
"doc_count": 15,
"date": "18 sept"
},
{
"doc_count": 16,
"date": "19 sept"
}
]
}
}
},
"a": "not needed",
"b": "not needed"
}
对象的数量是动态的，我通过ajax调用获得，这个json是在ajax调用之后创建的。我试图过滤掉json到所需的格式，其中对象的数量取决于日期的数量
Desired输出应该类似于
[
{
"Key_as_string": "25aug",
"values": [
{
"label": "open-issues",
"doc_count": 10
},
{
"label": "closed-issues",
"doc_count": 10
},
{
"label": "exempted-issues",
"doc_count": 10
}
]
},
{
"Key_as_string": "26aug",
"values": [
{
"label": "open-issues",
"doc_count": 10
},
{
"label": "closed-issues",
"doc_count": 10
},
{
"label": "pending-issues",
"doc_count": 10
}
]
}
]
我如何使用javascript或jquery
答案 0 :(得分：0)
我们的想法是将所有问题展平为一个数组，然后按日期分组，最后将其构建为所需的格式。
const payload = [
{
"data": {
"aggregations": {
"openissue": {
"buckets": [{
"doc_count": 5,
"date": "25 aug"
},
{
"doc_count": 6,
"date": "26 aug"
},
{
"doc_count": 7,
"date": "27 aug"
},
{
"doc_count": 8,
"date": "28 aug"
}
]
}
}
},
"a": "not needed",
"b": "not needed"
},
{
"data": {
"aggregations": {
"closeissue": {
"buckets": [{
"doc_count": 9,
"date": "29 aug"
},
{
"doc_count": 10,
"date": "30 aug"
},
{
"doc_count": 11,
"date": "31 aug"
},
{
"doc_count": 12,
"date": "1 sept"
}
]
}
}
},
"a": "not needed",
"b": "not needed"
}, {
"data": {
"aggregations": {
"pendingissue": {
"buckets": [{
"doc_count": 13,
"date": "10 sept"
},
{
"doc_count": 14,
"date": "13 sept"
},
{
"doc_count": 15,
"date": "18 sept"
},
{
"doc_count": 16,
"date": "19 sept"
}
]
}
}
},
"a": "not needed",
"b": "not needed"
}
]
//
let flat = []
payload.forEach(item => {
const preIssueType = Object.keys(item.data.aggregations)[0]
item.data.aggregations[preIssueType].buckets.forEach(issue => {
flat.push({label: preIssueType, doc_count: issue.doc_count, date: issue.date})
})
})
const grouped = _.groupBy(flat, 'date')
let result = []
for(const key in grouped){
result.push({'Key_as_string': key, values: grouped[key]})
}
console.log(result)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js"></script>
忘了说，lodash不是强制性的，但会为你节省一些编码工作。
