How to attach an event listener to an HTML element with only an ID using Vue 3 and TypeScript (without directly accessing the element)

Currently, I am faced with a challenge while using a gantt chart Vue 3 component, which is a module that I have imported. Unfortunately, I do not have access to the underlying html of this component. Although I can view the ids and classes used through the Chrome inspector, I am unable to add a ref property or attach events as I cannot directly modify the html for each element. My workaround involved utilizing CSS to include a scroll bar for a specific id, but now I require adding an event listener to that particular element. How can I achieve this in Vue 3 using Typescript? The main purpose behind adding this event listener is to synchronize scrolling between two separate scroll areas. Given that I already have a scroll event implemented on my component, I need to find a way to interact with the scroll event of the external module's html element as well.

It's important to keep in mind that a Vuejs app functions like any typical web app, allowing you to utilize Javascript in various ways. Thus, it is advisable to have a strong foundation in Javascript in addition to learning Vuejs.

In response to your query, you can easily select your element by its ID and then assign any desired event to it:

const yourElement = document.getElementById('your-element-id')
// Ensure the element exists
if (yourElement) {
  yourElement.addEventListener('click', () => {
    // Perform actions here
  })
}

To successfully execute this method, there are two key factors to consider:

The element must already be present before being accessed
The ID should remain consistent

To address the first factor, accessing your element after rendering the chart is recommended. Utilizing nextTick or setTimeout functions could prove beneficial in this scenario.

As for the second factor, it largely depends on the specific library being utilized.

Unfortunately, it appears that you are unable to do so.

To find a solution, please take a look at this resource and select one of the events listed there. Based on the documentation you provided, I have identified the following events:

mousedown-bar
mouseup-bar
dblclick-bar
mouseenter-bar
mouseleave-bar
dragstart-bar
drag-bar
dragend-bar
contextmenu-bar

It is important to note that you do not necessarily need to access the HTML within a component to determine where to bind events. However, keep in mind that you cannot force events in components that do not emit such events.
