[英]Creating a Generic Type in Typescript
I had a problem with generic types.我遇到了泛型类型的问题。 I have a user defined type(interface) like this:
我有一个像这样的用户定义类型(接口):
IList1: {
prop1: string,
prop2: number,
prop3: string
.
.
.
}
IList2:...
IList3:...
and after some serverside response, I get response in the type of Array<Array<,IListx>> .在一些服务器端响应之后,我得到了Array<Array<,IListx>>类型的响应。 So I tried to create a function like this:
所以我尝试像这样创建一个 function :
function fun<T>(args:T):Array<Array<T>> {
return Array<Array<typeof args>>;
}
and variables like this:和这样的变量:
let a:fun<IList1> = ...;
let b:fun<IList2> = ...;
let x:fun<IListx> = ...;
This didn't work.这没有用。 Also I'm not sure this is the correct way of creating a generic type.
另外我不确定这是创建泛型类型的正确方法。 I know I did something wrong but couldn't find the proper solution.
我知道我做错了什么,但找不到合适的解决方案。 Any help would be appreciated.
任何帮助,将不胜感激。
After some trials, I think I found a way by both defining and initializing:经过一些试验,我想我通过定义和初始化找到了一种方法:
function fun<T>():Array<Array<T>> {
return Array<Array<T>>();
}
let a= fun<IList1>();
let b= fun<IList2>();
worked as expected.按预期工作。 I don't know if there are possible better solutions.
我不知道是否有更好的解决方案。
