1. sort → new_ary click to toggle source sort { |a, b| block } → new_ary Returns a new array created by sorting self. Comparisons for the sort will be done using the <=> operator or using an optional code block. The block must implement a comparison
注:对象排序,就是对对象中的某一字段进行比较,以正序或倒序进行排序. 例: 需要排序的对象: public class Person { public int age; public String name; public Person (int age, String name){ this.age = age; this.name = name; }} 实现排序功能的类: import java.util.Comparator; public class OrderUtil imple
1.定义函数 /** * 数组对象排序函数 * @param {any} name 排序字段 * @param {any} order 升.降(这里事true.false记得处理下) */ var by = function (name,order) { return function (o, p) { var a, b; if (typeof o === "object" && typeof p === "object" && o
封装排序方法 对象排序方法 function compare(arr,styleName){ arr.sort((a,b)=>{ let x=a[styleName]; let y=b[styleName]; return x-y; }) } 数组排序方法 function compare(a,b){ return a-b; }
