Pre-Steps

In order to use this npm package there are a few pre-steps that need to be done first.

1. Ensure that the component that you are attaching the event listener to as well as the component that the event listener will be affecting all have ids attached to them. This will allow the functionality selector to find the elements through the dom.
2. If you have any video/audio content ensure that it is displayed using the azure media player and that it is wrapped in a div. The div must have an id attached to it and the video tag itself must have the same id with a "-vid" attached to it. This is because the different functionality will be attached to wither the div or the video depending on what type of event you want the functionality to trigger on. It might also be able to work on normal video tags that follow this format but this has not been tested.

Usage

After the pre-steps are done, this function is easy to call. Import the FunctionalitySelector method and the IFuncParams interface into your component. Then within the componentDidMount function of react, call the FunctionalitySelector with the appropriate parameters.

Example to toggle the visibility of a element when you click on the main element :

1let compId = "example-1"
2
3const funcInfo : IFuncParams[] = [
4    {
5        type: "click",
6        func: "showHide",
7        funcData: [{
8            id: "example-2"
9        }]
10    }
11]
12
13componentDidMount() {
14    FunctionalitySelector(compId, "Any Component type" funcinfo, true)
15}
