off
By using the off method, you can unregister the registered event handler to stop listening for the event.
Here is an example demonstrating how to use the off method to remove event listeners:
<script src="https://cdn.jsdelivr.net/gh/kirakiray/ofa.js@4.5.26/dist/ofa.min.js"></script>
<button id="target">add count</button>
<br>
<br>
<div id="logger" style="border:red solid 1px;padding:8px;">-</div>
<script>
let count = 0;
const f = ()=> {
$("#logger").text = count++;
if(count === 3){
$("#target").off("click", f);
}
}
$("#target").on("click", f);
</script>
In this example, we registered a click event handler f. When the button is clicked, the event handler will display the click count in #logger. Using the off method, we cancelled the event listener when the click count reaches 3.
