// example
+var arr = [
+            {"code":"000001","name":"上证指数","type":"指数","value":1000},
+            {"code":"000002","name":"A股指数","type":"指数","value":2000},
+            {"code":"000003","name":"B股指数","type":"指数","value":3000}
+          ];
+
+// 查询 code 大于 "000002" 并且 name 等于 "B股指数" 的数据，参数名前要加上符号 "@"
+// 查询语法关键词(用过sql的都懂的)：AND OR <> NOT = > < >= <= 
+// 也可自己在代码中扩展自定义查询语法
+arr.Query('@code>="000002" OR @value=3000'); 
+return [{...},{...},...];
+// 按照表达式输出结果
+arr.Select('@code,@value=3000,"nametype":@name+"#"+@type'); 
+return [{"code":"000001","value":"1000","nametype":"上证指数#指数"},{...},...];
+// 按照表达式拼接字符串
+arr.Join('@name+"#"+@type','|'); 
+return "上证指数#指数|A股指数#指数|B股指数#指数";
+// 查询第一个符合条件的元素的下标
+arr.IndexOf('@code>="000002"');
+return 1;
+// 删除并返回符合条件的元素
+arr.Remove('@code>="000002" OR @value=3000');
+return [{...},{...},...];
+// 正序
+arr.OrderBy("code"); 
+return [{...},{...},...];
+// 倒序
+arr.OrderByDesc("code"); 
+return [{...},{...},...];
