javascript - 使用 node.js 从 json 数据中过滤值

Question

这里是json数据

var myArray = [{  
        id: '71',   
        os: 'VM-WIN7-64'
    }, {    
        id: '45',
        mode: 'weekly',
        os: 'VM-WIN7-32'
    }, { 
        id: '37',   
        os: 'VM-WIN7-64',
    }, { 
        id: '67',
        mode: 'daily',
        os: 'VM-WIN7-32-1',
    }];

从这里我如何才能过滤 mode:daily, mode:weekly 如下。我必须删除除 mode:daily``mode 之外的其他值:每周

var myArray = [{    
        id: '45',
        mode: 'weekly',
        os: 'VM-WIN7-32'
    }, { 
        id: '67',
        mode: 'daily',
        os: 'VM-WIN7-32-1',
    }];

Answer 1

使用 Array#filter方法。

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

myArray = myArray.filter(function(o){
    return (o.mode === 'weekly' || o.mode === 'daily');
});
