javascript - lodash通过多个过滤器过滤数据

Question

我有这些数据，需要使用 lodash 应用所有过滤器。最终输出为空白。

filters = [{'gender':'M'}, {'division':'police'}]

data = [{'name':'tom', 'gender':'M', 'division':'police'},
        {'name':'bob' , 'gender':'M', 'division':'police'},
        {'name':'dave' , 'gender':'F', 'division':'IT'},
        ]

data = _.filter(data, function(item){			
      _.forEach(filters, function(filter){					
            data_found = _.filter([item], filter)
            console.log('data_found - ', data_found)
        })        
      })	

console.log(data)

Answer 1

您可以将过滤器数组组合到单个对象并将其用作过滤器

combined = filters.reduce((acc,item) =>  ({...acc, ...item})) 
// combined is = {'gender':'M', 'division':'police'}

data = _.filter(data, combined)

如果您不想使用其余运算符，可以使用 lodash function将对象数组组合成单个对象
