Error when content with fixed position on scroll in yjose reactjs-popup

Explanation of the problem

Problem: In the new major version 2.0.3 of a tooltip component, the position of the tooltip inside a navigation bar becomes incorrect after scrolling the window. The issue can be seen in the provided test case link (https://codesandbox.io/s/reactjs-popup-issue-position-fixed-vpeih).

Cause: The problem is caused by the following line of code, which sets the top and left position of the tooltip to the current coordinates of the cursor, plus the current scroll values of the window:

contentRef.current.style.top = `${cords.top + window.scrollY}px`;
contentRef.current.style.left = `${cords.left + window.scrollX}px`;

This results in the tooltip’s position changing when the window is scrolled, which is not the expected behavior.

Expected behavior: The tooltip should maintain a fixed position on the content, regardless of the scroll values of the window.

Problem solution for error when content with fixed position on scroll in yjose reactjs-popup

One solution to resolve an issue with content with fixed position on scroll in yjose reactjs-popup is to use the CSS position property. By setting the position property to “fixed” on the content element, it will remain in the same location on the screen even when the window is scrolled.

In Javascript, this can be done by adding the following line of code to the element’s style:

contentRef.current.style.position = “fixed”;

Alternatively, you can also accomplish this by adding the position property with a value of “fixed” in a CSS class, and then applying that class to the element.

Another solution would be to update the positioning coordinates of the tooltip element in an event listener for the window’s scroll event, rather than updating them only when the tooltip is opened. This would ensure that the tooltip’s position stays accurate as the user scrolls the page.

An example of this would be:

window.addEventListener("scroll", () => {
  contentRef.current.style.top = `${cords.top + window.scrollY}px`;
  contentRef.current.style.left = `${cords.left + window.scrollX}px`;
});

This way the position of tooltip would be updated on every scroll event and would not be affected by the scroll.

Other popular problems with yjose reactjs-popup

Problem: Content with fixed position on scroll

With the new major version of yjose reactjs-popup, users have reported issues with the fixed position of content inside a navigationbar when scrolling the window. The problem is caused by the following code:

contentRef.current.style.top = `${cords.top + window.scrollY}px`;
contentRef.current.style.left = `${cords.left + window.scrollX}px`;

where the top and left positions of the content are set to the sum of the coordinates and the scroll values of the window.

Solution:

To resolve this issue, the fixed position of the content should be set independent of the scroll values of the window. This can be achieved by setting the position value to “fixed” and using CSS to control the top and left positions.

contentRef.current.style.position = "fixed";
contentRef.current.style.top = `${cords.top}px`;
contentRef.current.style.left = `${cords.left}px`;

Problem: Opening and closing animation issues

Some users have reported issues with the animation of the popup while opening and closing. The animation may be choppy or may not work at all.

Solution:

To resolve this issue, it is recommended to use CSS transitions to control the animation of the popup. This can be done by adding transition properties to the CSS class of the popup, such as transition-duration, transition-timing-function, and transition-property.

Problem: Popup not closing on overlay click

Some users have reported that the popup does not close when clicking on the overlay.

Solution:

To resolve this issue, it is recommended to add an onClick event to the overlay that triggers the function to close the popup.
