在猫鼬的find()查询中,我得到的结果是:
[
{
"services":[
{
"location":[
17.4374614,
78.4482878
]
},
{
"location":[
17.4020637,
78.48400519999996
]
},
{
"location":[
17.387031788259197,
78.47838450137715
]
}
]
}
]
是否有任何方法可以提取输出,使得我只需要一个位置值的数组,例如:-
[
'17.4374614',
'78.4482878',
'17.4020637',
'78.48400519999996',
'17.387031788259197',
'78.47838450137715'
]
编辑:我知道map方法可以完成这项工作,但是我无法找到解决上述查询的map方法的方法。
我的模式:
var serviceSchema = new mongoose.Schema({
location:[{type: Number}]
})
答案 0 :(得分:0)
我使用了for-of循环和map函数来获得所需的结果
var your_output =[
{
"services":[
{
"location":[
17.4374614,
78.4482878
]
},
{
"location":[
17.4020637,
78.48400519999996
]
},
{
"location":[
17.387031788259197,
78.47838450137715
]
}
]
}
]
var location_array = []
for (var services of output[0].services) {
for(var loc of services.location){
location_array.push(loc)
}
}
location_array.map(String)
