Js Linq

Linq是对前端集合变量进行操作的一种技术框架,引用文件linq.min.js。
var myList = [
            { Name: "Victor", Age: 28 },
            { Name: "Jack", Age: 30 },
            { Name: "Simon", Age: 26 },
            { Name: "Hellen", Age: 27 },
            { Name: "Felix", Age: 28 }
    ];
1.where条件筛选
var results=myList .where(function(t){return t.Name=="Victor"});
//返回[{ Name: "Victor", Age: 28 }]

2.select获取指定的属性
var results=myList .select(function(t){return t.Age});
//返回[28, 30, 26, 27, 28]

3.orderBy排序
var results=myList.orderBy(function(t){return t.Age});
//返回[{ Name: "Simon", Age: 26 }, { Name: "Hellen", Age: 27 },{ Name: "Victor", Age: 28 }, { Name: "Felix", Age: 28 }, { Name: "Jack", Age: 30 }]

4.distinct去重
var results=myList.distinct(function(a,b){return a.Age==b.Age});
//[{ Name: "Simon", Age: 26 }, { Name: "Hellen", Age: 27 },{ Name: "Victor", Age: 28 }, { Name: "Jack", Age: 30 }]

5.forEach遍历
myList.forEach(function(value,index){console.log("Name:"+value.Name+"Age:"+value.Age);})
