用TypeScript创建一个自定义的Angular过滤器 [英] Creating a custom Angular filter with TypeScript
问题描述
我看到的所有代码示例都是这样使用的:
> myModule.filter(myFilter,function()
{
返回函数(输入)
{
//过滤这里的东西
返回结果;
}
}
...这工作,但似乎混乱,因为我想保持我所有的过滤代码分开。所以我想知道如何声明过滤器作为一个单独的文件(例如filters / reverse-filter.ts)所以我可以像这样创建它:
$ $ $ $ $ $ $ $ myModule.filter(filterName,moduleName.myFilter);
code>
...与控制器,服务等相同的方式。
< TS和Angular在一起的文档似乎很薄弱,特别是在过滤器方面 - 任何人都可以帮忙吗?
干杯!
<可以从这样的模块中导出函数:
pre $ module $ module $ module $ {
export function myFilter()
{
返回函数(输入)
{
//过滤这里的东西
返回结果;
$ / code $ / pre
然后在模块之外: / p>
myModule.filter(filterName,moduleName.myFilter);
然后就可以做一些事情,比如自动注册 moduleName
模块迭代其公共属性。
I'm trying to work out the best way of creating a custom Angular Filter with TypeScript.
All the code samples I see use something like:
myModule.filter( "myFilter", function()
{
return function( input )
{
// filter stuff here
return result;
}
}
... which works, but seems messy as I want to keep all my filter code separate. So I want to know how to declare the filter as a separate file (eg filters/reverse-filter.ts) so I can create it like:
myModule.filter( "filterName", moduleName.myFilter );
... the same way you would for Controllers, Services etc.
The documentation for TS and Angular together seems pretty thin on the ground, especially where filters are concerned - can anyone help out?
Cheers!
Functions can be exported from modules like this:
module moduleName {
export function myFilter()
{
return function(input)
{
// filter stuff here
return result;
}
}
}
then outside the module:
myModule.filter("filterName", moduleName.myFilter);
Then it would then be possible to do things like automatically register all of the filters defined in the moduleName
module by iterating over its public properties.
