未捕获的类型错误：elem.getClientRects 不是在 MVC 上使用多选时的函数

Question

Uncaught TypeError: elem.getClientRects is not a function

    at HTMLDivElement.dispatch (jquery-3.2.1.js:5206)
    at HTMLDivElement.elemData.handle (jquery-3.2.1.js:5014)

I was trying 2 ways such as HTML and MVC on http://demos.telerik.com/kendo-ui/multiselect/index

But it will display errors. on MVC, added

  <script src="js/jquery.min.js"></script>
   <script src="js/kendo.all.min.js"></script>

• Jquery version is 3.2.1

Answer 1

According the error, elem seems like a jQuery object.

jQuery objects don't have a getClientRects method, only native DOM nodes does, so you probably want to extract the underlying DOM node first, using get()

elem.get(0).getClientRects()

Answer 2

You need the proper mix of jquery and jquery-ui .

The combo required to use the new jquery version 3 is:

https://code.jquery.com/ui/1.12.1/jquery-ui.min.js
https://code.jquery.com/jquery-migrate-3.0.0.js

Migrate is also needed.
