如何在 TypeScript 中实现 jQuery 自动完成？

小开

最佳答案

You need to add a reference to the jQuery definition at the top of your .ts file.

/// <reference path="jquery.d.ts" />

You can find type annotations for jQuery in this sample.

Checklist of things that need to be set up for this to work:

Ensure the TypeScript extension is installed. Check Tools -> Extension Manager and make sure "TypeScript for Microsoft Visual Studio" extension is installed. If it isn't, run the .vsix file found in the TypeScript folder (Program Files\Microsoft SDKs\TypeScript\<version>) to install the extension.
Ensure your file references the jquery.d.ts file. You should have a comment at/near the top of your file that looks like this:

/// <reference path="the/path/to/jquery.d.ts" />

If you need to download it, you can find the jquery.d.ts file as part of the Warship sample at http://www.typescriptlang.org/Samples/

Check out these type definitions for TypeScript: https://github.com/borisyankov/DefinitelyTyped#readme. They're being updated regularly and are more complete than the ones in the examples. On Nuget: http://www.nuget.org/profiles/DefinitelyTyped/
