Issue - PerfectScrollbar : Unable to call a function on a type without a defined call signature. The data type 'Number' does not have any suitable call signatures

The following code is running smoothly:-

$(".info).scrollTop(0);

However, the equivalent code below is encountering an error:-

let ele : HTMLElement =  document.querySelector('.info');
 ele.scrollTop(0);  <---- Error

Error: - Error - PerfectScrollbar : Cannot invoke an expression whose type lacks a call signature. Type 'Number' has no compatible call signatures

Answer №1

The two methods are not equal.

In the initial example, JQuery is utilized and the object returned by it features a method called scrollTop.

Contrastingly, the following example makes use of the browser DOM api which delivers an HTMLElement. In this case, scrollTop is a number that denotes the scroll offset. To navigate to a specific position, the scrollTo method must be employed:

element.scrollTo({
  top: 10
})
