问题描述

这是使用PHP产生JSON

  [{卖:{ID:1,CUSTOMER_ID:创建,15,:1,量,2014- 05-17}}]

排序依据:ID 显然是行不通的。我在一个排序依据功能需要为这种数据结构要创建其他职位读取。我不能够创建功能。谁能告诉我什么是解决这个正确的方法是什么?


解决方案

这些类型的数据操纵我喜欢让他们在适当的角度对象,因为这个原因我会创造我的自定义过滤器,是这样的:

  VAR sampleSource = [{卖:{ID:8,CUSTOMER_ID:1,量:15,创造: 2014年5月17日}},{卖:{ID:5,CUSTOMER_ID:6,量:15,创造:2015年5月17日}}];VAR对myApp = angular.module('对myApp',[]);myApp.filter('myFilter',函数(){
 返回功能(项){
    items.sort(功能(A,B){
        如果(parseInt函数(a.Sale.id)GT; parseInt函数(b.Sale.id))
            返回1;
        如果(parseInt函数(a.Sale.id)LT; parseInt函数(b.Sale.id))
            返回-1;
        返回0; })
});


  

重要:我推荐的自定义过滤器,因为个人preference我不喜欢超负荷我的控制器或其他物体与任务(code),我可以在其他对象分开这给了我更多的独立性和清洁code(我爱约角度的原因之一),但是除此之外的个人preference我会说,这是的的唯一途径,但如果你分享它背后我的原因,我希望它能帮助。


This is the json that is generated using PHP

[{"Sale":{"id":"1","customer_id":"1","amount":"15","created":"2014-05-17"}}]

Doing orderBy:id is obviously not working. I read in other posts that an orderBy function needs to be created for this kind of data structure. I am not able to create the function. Can anyone please tell me what is the correct way to approach this?

解决方案

These type of data manipulations I like to keep them in the proper angular objects and for that reason I would create my custom filter, something like:

var sampleSource=  [{"Sale":{"id":"8","customer_id":"1","amount":"15","created":"2014-05-17"}}, {"Sale":{"id":"5","customer_id":"6","amount":"15","created":"2015-05-17"}}];

var myApp = angular.module('myApp',[]);

myApp.filter('myFilter', function() {
 return function(items) {  
    items.sort(function(a,b){   
        if (parseInt(a.Sale.id) > parseInt(b.Sale.id))
            return 1;
        if (parseInt(a.Sale.id) < parseInt(b.Sale.id))
            return -1;         
        return 0; })
});

Important: I recommend the custom filter because as personal preference I do not like to overload my controllers or other objects with tasks(code) that I can separate on other objects which gives me more independence and cleaner code(one of the things I love about angular) but besides this personal preference I would say that this is not the only way but if you share my reasons behind it I hope it helps.
