Angularjsfilter filter _ AngularJS

This article mainly introduces angularjsfilter filter related information. If you need it, you can refer to the system to learn angularjs. It is found that some ideas of angularjs are similar to the php module smarty, such as data binding, filter. If you are familiar with smarty, learning angularjs is easier. The filter function of angularjs can be divided into two types: built-in filter and custom filter.

Filter is used to format data.

Basic Filter prototype (''is similar to the pipeline mode in Linux ):

{{ expression filter }}

Filters can be chained (that is, multiple filters are used continuously ):

{{ expression filter1 filter2 ... }}

Filter can also specify multiple parameters:

{{ expression filter:argument1:argument2:... }}

1. built-in filters

1, uppercase, lowercase size conversion

{"Lower cap string" | uppercase} // result: lower cap string {"TANK is GOOD" | lowercase} // result: tank is good

| The vertical line here is a pipeline function. If you are familiar with linux, this line is used. | the Pipeline Function of the root linux is basically the same.

2. json format

{Foo: "bar", baz: 23} | json} // result: {"foo": "bar", "baz": 23}

Note: bza is not formatted with double quotation marks. After formatting, it is converted into json data.

3, date Format

{1304375948024 | date }}// result: May 3, 2011 {1304375948024 | date: "MM/dd/yyyy @ h: mma" }}// result: 05/03/2011 @ 06:39:08 AM {1304375948024 | date: "yyyy-MM-dd hh: mm: ss"} // result:

4. number formatting

{1.234567 | number: 1 }}// result: 1.2 {1234567 | number} // result: 1,234,567

5. Format currency

{250 | currency }}// result: $250.00 {250 | currency: "RMB ￥" }}// result: RMB ￥250.00

6. filter search

{[{"Age": 20, "id": 10, "name": "iphone" },{ "age": 12, "id": 11, "name": "sunm xing" },{ "age": 44, "id": 12, "name": "test abc"}] | filter: 'S '} // find the row containing s // result of the preceding example: [{"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 '}}// find the row whose name is iphone // result of the previous example: [{"age": 20, "id": 10, "name ": "iphone"}]

7, limitTo string, screenshot of the image

{"I love tank" | limitTo: 6} // result: I love {"I love tank" | limitTo:-4} // result: tank {[{"age": 20, "id": 10, "name": "iphone" },{ "age": 12, "id": 11, "name": "sunm xing" },{ "age": 44, "id": 12, "name": "test abc"}] | limitTo: 1 }}// result: [{"age": 20, "id": 10, "name": "iphone"}]

8. Order

{[{"Age": 20, "id": 10, "name": "iphone" },{ "age": 12, "id": 11, "name": "sunm xing" },{ "age": 44, "id": 12, "name": "test abc"}] | orderBy: 'id ': true }}// sort the root id in descending order {[{"age": 20, "id": 10, "name": "iphone" },{ "age ": 12, "id": 11, "name": "sunm xing" },{ "age": 44, "id": 12, "name ": "test abc"}] | orderBy: 'id'} // sort by id in ascending order

Ii. Custom filter Function

I found a mvc Framework of angularjs, phonecat, and custom filter, which is also written on this basis. This framework is quite useful.

1. Add a module to filters. js.

angular.module('tanktest', []).filter('tankreplace', function() { return function(input) { return input.replace(/tank/, "=====") }; }); 

2. Load the module in app. js.

var phonecatApp = angular.module('phonecatApp', [ 'ngRoute', 'phonecatControllers', 'facebookControllers', 'tanktest' ]); 

3, called in html

{"TANK is GOOD" | lowercase | tankreplace} // result: ==== is good

Note: | lowercase | the tankreplace pipeline command can have multiple
