let arr:array = []
// 取最大值：Math.max.apply(Math, arr.map(function(o) {return o.value}))
// 取最小值：Math.min.apply(Math, arr.map(function(o) {return o.value}))

var array=[
{
“index_id”: 111,
“area_id”: “18335623”,
“name”: “满意度”,
“value”: “100”
},
{
“index_id”: 112,
“area_id”: “18335624”,
“name”: “满意度”,
“value”: “20”
}, {
“index_id”: 114,
“area_id”: “18335524”,
“name”: “满意度”,
“value”: “10”
},
{
“index_id”: 113,
“area_id”: “18335625”,
“name”: “满意度”,
“value”: “80”
}
];

Math.min.apply(Math, array.map(function(o) {return o.value}))

就这样获取了最大和最小数据
