javascript 从对象数组中 按字段/属性取最大值或最小值

Posted 2023-01-04 subendong

var array=[
        
            "index_id": 119,
            "area_id": "18335623",
            "name": "满意度",
            "value": "100"
        ,
        
            "index_id": 119,
            "area_id": "18335624",
            "name": "满意度",
            "value": "20"
        ,
        
            "index_id": 119,
            "area_id": "18335625",
            "name": "满意度",
            "value": "80"
        
];

取最大值：Math.max.apply(Math, array.map(function(o) return o.value))

取最小值：Math.min.apply(Math, array.map(function(o) return o.value))

说明：array是我们上面定义的数组，o.value就是要比较的字段。
