I create a debounced version of a function with underscore:
var debouncedThing = _.debounce(thing, 1000);
Once debouncedThing is called...
debouncedThing();
...is there any way to cancel it, during the wait period before it actually executes?
If you use the last version of lodash you can simply do:
// create debounce
const debouncedThing = _.debounce(thing, 1000);
// execute debounce, it will wait one second before executing thing
debouncedThing();
// will cancel the execution of thing if executed before 1 second
debouncedThing.cancel()
Another solution is with a flag:
// create the flag
let executeThing = true;
const thing = () => {
// use flag to allow execution cancelling
if (!executeThing) return false;
...
};
// create debounce
const debouncedThing = _.debounce(thing, 1000);
// execute debounce, it will wait one second before executing thing
debouncedThing();
// it will prevent to execute thing content
executeThing = false;
