The use of the deprecated initMouseEvent method

[Lemraj]

Issue:
TS6387 (JS) The signature '(typeArg: string, canBubbleArg: boolean, cancelableArg: boolean, viewArg: Window, detailArg: number, screenXArg: number, screenYArg: number, clientXArg: number, clientYArg: number, ctrlKeyArg: boolean, altKeyArg: boolean, shiftKeyArg: boolean, metaKeyArg: boolean, buttonArg: number, relatedTargetArg: EventTarget): void' of 'evt.initMouseEvent' is deprecated.

Possible solution:
The warning is due to the use of the deprecated initMouseEvent method, which has been replaced by MouseEvent constructors in modern JavaScript.

To resolve this warning, you can update the code that uses evt.initMouseEvent to use the MouseEvent constructor instead. Here is an example of how you can migrate from initMouseEvent to MouseEvent:

Old (deprecated) way with initMouseEvent:

var evt = document.createEvent('MouseEvent'); evt.initMouseEvent('click', true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null); element.dispatchEvent(evt);

New way using the MouseEvent constructor:

var evt = new MouseEvent('click', { bubbles: true, cancelable: true, view: window, detail: 1, screenX: 0, screenY: 0, clientX: 0, clientY: 0, ctrlKey: false, altKey: false, shiftKey: false, metaKey: false, button: 0, relatedTarget: null }); element.dispatchEvent(evt);
