unicorn/no-invalid-remove-event-listener Correctness ​
What it does ​
It warns when you use a non-function value as the second argument of removeEventListener
.
Why is this bad? ​
The removeEventListener
function must be called with a reference to the same function that was passed to addEventListener
. Calling removeEventListener
with an inline function or the result of an inline .bind()
call is indicative of an error, and won't actually remove the listener.
Example ​
Examples of incorrect code for this rule:
javascript
el.removeEventListener("click", () => {});
el.removeEventListener("click", function () {});
Examples of correct code for this rule:
javascript
el.removeEventListener("click", handler);
el.removeEventListener("click", handler.bind(this));
How to use ​
To enable this rule in the CLI or using the config file, you can use:
bash
oxlint --deny unicorn/no-invalid-remove-event-listener
json
{
"rules": {
"unicorn/no-invalid-remove-event-listener": "error"
}
}
