Property does not exist on type JQueryStatic

Question

I have written a jQuery plugin where I use jQuery's internal _data method. Which leads to the above compiler error.

(function ($) {     

var evts = $._data(document, 'events'); // internal method
....

Can I supress this error and how? What is the recommended way to approach this issue?

I know I could do the following:

$["_data"]

or

($ as any)._data

but I would prefer making a $._data a valid method call.

Answer 1

but I would prefer making a $._data a valid method call.

The types intentionally don't allow internal API calls as the jquery team doesn't want you to use these methods . If you want to write unsafe code like this you are free to use $ as any as you have figured out.

If you want such unsafe access to be done safely you can extend the JQuery interface with new functionality

interface JQuery {
  _data: any; // Replace with your types
}

Answer 2

你可以试试：

declare var $: any;
