Question

I have just downloaded the TypeScript documentation. I have a some JavaScript classes and I would like to create and use these class in a TypeScript test application

How can I call a JavaScript function of an included JavaScript from TypeScript. I do not want to create a “d.ts” file. Just to create my classes, call its methods, access its properties.

How do I do that?

I am trying to use kendoUI with TypeScript.

For instance to show a window I have to do:

1. Have a HTML to represent the content of a window. I have a div with an id logonDialog. This div
   is initially hidden;
2. I create the window: logonDlg.kendoWindow(logOnParams);
3. Then using jQuery I show the div: using logonDlg.show();

Example

var logonDlg = $("logonDialog");

if (!logonDlg.data("kendoWindow")) {
   logonDlg.kendoWindow(logOnParams);
   logonDlg.show();
}

It is working OK. The JS is generated as I want but I receive an error since The property ‘kendoWindow’ does not exist on value of type ‘JQuery’.

How can I disable this kind of error. I could not make, what Ryan said, to work.

You just do it. TypeScript won’t stop you. You will see warnings in the compiler output but tsc will generate your JS file just fine.
