WebStorm 和 TypeScript 智能感知 [英] WebStorm and TypeScript intellisense

问题描述

我正在尝试为在 WebStorm 中工作的 TypeScript 获取智能感知.

I am trying to get intellisense for TypeScript working in WebStorm.

在我的测试中，我试图为 Knockout 获取它.

In my test here I am trying to get it for Knockout.

我已经添加了类型定义文件和其他必要的文件，在我的 .ts 文件的顶部添加了引用标签.

I have added the type definition file and other files necessary, added the reference tag to the top of my .ts file.

这是我设置的屏幕截图:

Here is a screenshot of my setup:

当我输入ko"时.我可以滚动列表并找到可观察的，但除此之外我没有其他智能感知.

When I type 'ko.' I can scroll through the list and find observable but other than that I get no other intellisense.

我的设置有问题吗?当我在输入 'ko.observable' 后打开一个括号时，我期望重载等是错误的吗?

Is there something wrong with my setup? Am I wrong to expect overloads and such when I open a paren after typing 'ko.observable'?

如果我改变线路

declare var ko : KnockoutState

到

declare var ko : KnockoutObservable<string>;

我收到错误

'Error:(3, 13) TS2403: 后续变量声明必须具有同类型.变量ko"必须是KnockoutStatic"类型，但这里类型为KnockoutObservable".

'Error:(3, 13) TS2403: Subsequent variable declarations must have the same type. Variable 'ko' must be of type 'KnockoutStatic', but here has type 'KnockoutObservable'.

(更新)注意:我提到上述错误只是为了表明它似乎正在读取 Knockout 的类型定义.当我把它留在 KnockoutStatic 或完全删除类型时，我仍然没有得到任何智能感知.

(UPDATE) NOTE: I mention the above error only to show that it does seem to be reading the type definition for Knockout. I still do not get any intellisense when I leave it at KnockoutStatic or remove the type out completely.

推荐答案

当我输入ko"时.我可以滚动列表并找到可观察的，但除此之外我没有其他智能感知.

When I type 'ko.' I can scroll through the list and find observable but other than that I get no other intellisense.

您需要在代码中使用它来获取智能感知.我可以看到你尝试过:

You need to use it in code to get intellisense. I can see you tried that with :

declare var ko : KnockoutObservable<string>;

这是一个无效用法......因此你得到了错误TS2403.

Which is an invalid usage ... and hence you got the error TS2403.

正确使用ko:

var myObservableArray = ko.observableArray<any>();  // intellisense on `ko.`
myObservableArray.push('Some value');               // intellisense on `.p`
var anotherObservableArray = ko.observableArray([
    { name: "Bungle", type: "Bear" },
    { name: "George", type: "Hippo" },
    { name: "Zippy", type: "Unknown" }
]);
