用途：方便js操作查詢json數據。

下載網址：http://jslinq.codeplex.com/

使用方法：只需要引用linq.js即可。

查詢方法：

一、where查詢

var myList = [{ Name: "Jim", Age: 20 },{ Name: "Kate", Age: 21 },{ Name: "Lilei", Age: 18 },{ Name: "John", Age: 14 },{ Name: "LinTao", Age: 25 } ]; var arrRes = Enumerable.From(myList).Where("x=>x.Name=='Jim'").ToArray();

?

二、排序：OrderBy

var myList = [{ Name: "Jim", Age: 20 },{ Name: "Kate", Age: 21 },{ Name: "Lilei", Age: 18 },{ Name: "John", Age: 14 },{ Name: "LinTao", Age: 25 } ]; var arrRes = Enumerable.From(myList).OrderBy("x=>x.Age").ToArray();//降序OrderByDescending()

　

?

三、去重：Distinct

var myList = [{ Name: "Jim", Age: 20 },{ Name: "Kate", Age: 20 },{ Name: "Lilei", Age: 20 },{ Name: "John", Age: 14 },{ Name: "LinTao", Age: 25 } ]; var arrRes = Enumerable.From(myList).Distinct("x=>x.Age").ToArray();

?

四、遍歷：ForEach

var myList = [{ Name: "Jim", Age: 20 },{ Name: "Kate", Age: 20 },{ Name: "Lilei", Age: 20 },{ Name: "John", Age: 14 },{ Name: "LinTao", Age: 25 }];Enumerable.From(myList).ForEach(function(value, index){document.write("值="+value+",索引="+index); });

?

五、取唯一對象：First、FirstOrDefault、Last、LastOrDefault、Single、SingleOrDefault

var myList = [{ Name: "Jim", Age: 20 },{ Name: "Kate", Age: 20 },{ Name: "Lilei", Age: 20 },{ Name: "John", Age: 14 },{ Name: "LinTao", Age: 25 } ]; var arrRes = Enumerable.From(myList).FirstOrDefault("x=>x.Age>18");

　

六、Skip、Take

Enumerable.Range(1,10).Skip(5)//結果[6,7,8,9,10] Enumerable.Range(1,10).Take(5)//結果[1,2,3,4,5]

　　

?
