javascript库 “linq.js” 的5种使用示例

今天研究了一下linq.js，很实用。
下面是写的几个小例子：
< html > <head > <script type = "text/javascript"src = "linq.min.js" > </script>

<script>
var peoples = [
    { Name: "张三峰", Sex: "男",City: "北京",Age:23 },
    { Name: "张三峰", Sex: "男",City: "北京",Age:11 },
    { Name: "韩美美", Sex: "女",City: "天津",Age:9 },
    { Name: "李丽丽", Sex: "女",City: "上海",Age:13 },
    { Name: "赵亮亮", Sex: "男",City: "重庆",Age:14 }
  ];

    var filteredPeoples = Enumerable.from(peoples).distinct("x=>x.Name").toArray();/ / 根据姓名去重dw(filteredPeoples, "去重");

var orderedPeoples = Enumerable.from(peoples).orderBy("x=>x.Age").toArray(); //正向排序
dw(orderedPeoples, "正向排序");

var orderedPeoples = Enumerable.from(peoples).orderByDescending("x=>x.Age").toArray(); //倒序
dw(orderedPeoples, "倒序");

var wherePeoples = Enumerable.from(peoples).where("x=>x.Name=='李丽丽'").toArray(); //Where条件
dw(orderedPeoples, "Where条件");

var firstPeople = Enumerable.from(peoples).firstOrDefault("x=>x.City=='北京'"); //Where条件
dw([firstPeople], "firstOrDefault取出首行");

//输入信息到屏幕
function dw(infos, title) {
    document.write("<b>" + title + "</b><br/>") Enumerable.from(infos).forEach(function(value, index) {
        document.write(value.Name + " - " + value.Sex + " - " + value.City + " - " + value.Age + "<br/>");
    });
    document.write("<br/><br/>")
} < /script>
</head > <body >
