系统的学习了一下angularjs,发现angularjs的有些思想根php的模块smarty很像,例如数据绑定,filter。如果对smarty比较熟悉的话,学习angularjs会比较容易一点。这篇简单说一下angularjs的filter功能,angularjs的filter功能可分为二种,一种是内置的过滤器,一种是自定义的。
一,内置的过滤器
1,uppercase,lowercase大小转换
查看复制打印?
{{ "lower cap string" | uppercase }} //结果:LOWER CAP STRING
{{ "TANK is GOOD" | lowercase }} //结果:tank is good
|这里的竖线是一种管道功能,如果对linux比较熟悉的话,这块的|根linux的管道功能,基本是一样的
2,json格式化
查看复制打印?
{{ {foo: "bar", baz: 23} | json }} //结果:{ "foo": "bar", "baz": 23 }
注意:bza没格式前是没有双引号的,格式化后就转换成了json数据了。
3,date格式化
查看复制打印?
{{ 1304375948024 | date }} //结果:May 3, 2011
{{ 1304375948024 | date:"MM/dd/yyyy @ h:mma" }} //结果:05/03/2011 @ 6:39AM
{{ 1304375948024 | date:"yyyy-MM-dd hh:mm:ss" }} //结果:2011-05-03 06:39:08
4,number格式化
查看复制打印?
{{ 1.234567 | number:1 }} //结果:1.2
{{ 1234567 | number }} //结果:1,234,567
5,currency货币格式化
查看复制打印?
{{ 250 | currency }} //结果:$250.00
{{ 250 | currency:"RMB ¥ " }} //结果:RMB ¥ 250.00
6,filter查找
查看复制打印?
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}
] | filter:'s'}} //查找含有有s的行
//上例结果:[{"age":12,"id":11,"name":"sunm xing"},{"age":44,"id":12,"name":"test abc"}]
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}
] | filter:{'name':'iphone'} }} //查找name为iphone的行
//上例结果:[{"age":20,"id":10,"name":"iphone"}]
7,limitTo字符串,对像的截取
查看复制打印?
{{ "i love tank" | limitTo:6 }} //结果:i love
{{ "i love tank" | limitTo:-4 }} //结果:tank
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}
] | limitTo:1 }} //结果:[{"age":20,"id":10,"name":"iphone"}]
8,orderBy对像排序
查看复制打印?
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}
] | orderBy:'id':true }} //根id降序排
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}
] | orderBy:'id' }} //根据id升序排
二,自定filter功能
我找了一个基本angularjs的mvc框架,phonecat,自定义filter也是在这基础写的,这个框架挺好用的。
1,filters.js添加一个module
查看复制打印?
angular.module('tanktest', []).filter('tankreplace', function() {
return function(input) {
return input.replace(/tank/, "=====")
};
});
2,app.js中加载这个module
查看复制打印?
var phonecatApp = angular.module('phonecatApp', [
'ngRoute',
'phonecatControllers',
'facebookControllers',
'tanktest'
]);
3,html中调用
查看复制打印?
{{ "TANK is GOOD" | lowercase |tankreplace}} //结果:===== is good
注意:| lowercase |tankreplace管道命令可以有多个
