排序，数组对象排序

排序，数组对象排序

数组对象排序法一：

let getTableData = JSON.parse(JSON.stringify(res.data.list))

let compare = function (property) {
  return function (obj1, obj2) {
    let val1= obj1[property]
    let val2 = obj2[property]
    return val2 - val1 // 降序
  }
}
getTableData.sort(compare('createTime'))
console.log(getTableData)

数组对象排序法二：

var compare1 = function (prop) {
  return function (obj1, obj2) {
    var val1 = obj1[prop]
    var val2 = obj2[prop]
    if (!isNaN(Number(val1)) && !isNaN(Number(val2))) {
       val1 = Number(val1)
       val2 = Number(val2)
    }
    // 降序
    if (val1 < val2) {
       return -1
    } else if (val1 > val2) {
       return 1
    } else {
       return 0
    }
  }
}

数组值排序：

var arr = [23, 9, 4, 78, 3];
var compare = function (x, y) { //比 较函数
    if (x < y) {
        return -1;
    } else if (x > y) {
        return 1;
    } else {
        return 0;
    }
}
console.log(arr.sort(compare));
