It's been a while that PyCharm (I suppose it's the same with WebStorm and other JetBrains IDEs) raise a weak warning on the event variables I use in my code.
For instance in the following code
<div id="my-div" onclick="event.preventDefault();">...</div> PyCharm displays this message "Deprecated symbol used, consult docs for better alternative".
The problem seems to be that the event variable refers to Window.event, and according to MDN Web Docs:
You should avoid using this property in new code, and should instead use the Event passed into the event handler function. This property is not universally supported and even when supported introduces potential fragility to your code.
I know that a correct workaround would be to write in a javascript tag:
document.getElementById("my-div").addEventListener("click", function(event) { console.log("And use this " + event + " instead"); }); I am just wondering what would be, if it exists, the correct way to use events in the HTML code (onclick attribute).

I do not know if it is still important for someone or not, but tested on WebStorm 2020.3 the following works, and the IDE does not complain about deprecation. Additionally, WebStorm identifies the event as Event.
Code snippet below.
(function() { const checkBox = document.querySelector("#id-checkbox"); checkBox.addEventListener('click', (event) => { event.preventDefault(); }, false); })();<head> <script src="click.js" defer></script> </head> <body> <p>Please click on the checkbox control.</p> <form> <label for="id-checkbox">Checkbox:</label> <input type="checkbox" id="id-checkbox"/> </form> <div id="output-box"></div> </body>If you love us?
