orderBy过滤器

是用于角度js的便捷工具。

orderBy渠道鼓励你对展览品进行排序。

当然, 它将按顺序请求对字符串进行排序, 并在数字请求中对数字进行排序。

语法如下:

{{ orderBy_expression | orderBy : expression : reverse }}

参数说明:

表达:

它用于决定请求。很可能是字符串, 作品或集群。

反转:是自由裁量权。如果希望以相反的顺序显示数据, 请确保参数中的反向条件设置为true。

示例:通过名称进行排序

<!DOCTYPE html>  
< html >  
< script src =
"https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js" >
</ script >  
< body >  
< div ng-app = "myApp" ng-controller = "orderCtrl" >  
< ul >  
< li ng-repeat = "x in customers | orderBy : 'name'" >  
     {{x.name + ", " + x.city}}  
</ li >  
</ ul >  
</ div >  
< script >  
var app = angular.module('myApp', []);  
app.controller('orderCtrl', function($scope) {  
     $scope.customers = [  
         {"name" : "Amber", "city" : "ajmer"}, {"name" : "lakshay ", "city" : "vizag"}, {"name" : "karan", "city" : "London"}, {"name" : "bhaskar", "city" : "peshawar"}, ];  
});  
</ script >  
< p >The array items are arranged by "name".</ p >  
</ body >  
</ html >

输出:

输出1

示例:当我们通过"-"和" +" orderBy遍历gdp时, 按情况进行排序
