如何使用lodash從對象中刪除屬性？

Question

這是我的目標：

var obj = { 
    "flag": false, 
    "text": "good text", 
    "someArray": [ 
    { 
     "questionId": 11, 
     "text": "qwe", 
     "TypeId": "B", 
     "source": "oooooo" 
    }, 
    { 
     "questionId": 12, 
     "text": "zxc", 
     "TypeId": "A", 
     "source": "pppppp" 
    }, 
    { 
     "questionId": 13, 
     "text": "asd", 
     "TypeId": "D", 
     "source": "cccccc" 
    } 
    ] 
} 

我試圖做的是從對象someArray性能TypeId和source刪除。我如何用lodash做到這一點？我正在嘗試使用_.pick，但我不知道如何在someArray中使用這個。

你想用的_.pick相反，這是_.omit通過與_.map

var obj = { 
 
    "flag": false, 
 
    "text": "good text", 
 
    "someArray": [{ 
 
    "questionId": 11, 
 
    "text": "qwe", 
 
    "TypeId": "B", 
 
    "source": "oooooo" 
 
    }, { 
 
    "questionId": 12, 
 
    "text": "zxc", 
 
    "TypeId": "A", 
 
    "source": "pppppp" 
 
    }, { 
 
    "questionId": 13, 
 
    "text": "asd", 
 
    "TypeId": "D", 
 
    "source": "cccccc" 
 
    }] 
 
} 
 

 
obj.someArray = _.map(obj.someArray, o => _.omit(o, ['TypeId', 'source'])); 
 

 
console.log(obj)
