如何检查mongodb中的值是否相同值

Question

我想检查值是否与mongodb聚合值相同。我想使用聚合方法查找结果。非常感谢你。

var id = 5995cc31f36d28126e46e670 

{ _id: 5995cc31f36d28126e46e670, 
    income: [ '23', '23', '232', '', '', '', '' ], 
    incomedetail: [ '23', '23', 'ew', '', '', '', '' ], 
    outcome: [ '23', '23', '43', '', '', '', '' ], 
    outcomedetail: [ '23', '23', 'fsdf', '', '', '', '' ], 
    date: 
    [ '2017-08-18', 
    '2017-08-18', 
    '2017-08-17', 
    '2017-08-11', 
    '2017-08-26', 
    '2017-08-26', 
    '11/02/2345' ] } 
{ _id: 5995d9f8f36d28126e46ed17, 
    income: [ '', '', '' ], 
    incomedetail: [ '', '', '' ], 
    outcome: [ '40', '40', '72' ], 
    outcomedetail: [ '23', '32', '32' ], 
    date: [ '2017-08-18', '2017-08-18', '2017-08-18' ] } 

输出

我不知道如果我理解你的问题，但也许这可以帮助你：

function exampleCheck(JSONObj, theID){ 
if(JSONObj._id == theID){ return "match"; } 
else{ return "no match"; } 
} 

var testObj = { 
    _id: 5995d9f8f36d28126e46ed17, 
    income: [ '', '', '' ], 
    incomedetail: [ '', '', '' ], 
    outcome: [ '40', '40', '72' ], 
    outcomedetail: [ '23', '32', '32' ], 
    date: [ '2017-08-18', '2017-08-18', '2017-08-18' ] 
}; 

console.log(exampleCheck(testObj, '5995cc31f36d28126e46e670'));
