debouncing

Lodash debounce isn't preventing dispatch as expected onChange

问题 Currently, I have a list of checkboxes that onChange will make a request to the server to return some data. However, I am using lodash debounce to try and make a request only when the user has stopped selecting the multi-checkbox after a certain amount of time. Currently, it prevents dispatching straight away but will dispatch after the debounce time has met rather when the user has stopped interacting with the checkboxes. Can someone tell me how I would achieve this or where I am going wrong

Lodash debounce with React Input

问题 I'm trying to add debouncing with lodash to a search function, called from an input onChange event. The code below generates a type error 'function is expected', which I understand because lodash is expecting a function. What is the right way to do this and can it be done all inline? I have tried nearly every example thus far on SO to no avail. search(e){ let str = e.target.value; debounce(this.props.relay.setVariables({ query: str }), 500); }, 回答1: The debounce function can be passed inline

Why rxjs debounceTime does not work on observables created using 'of' operator?

问题 Using angular 7 and rxjs 6 : <input (input)="onChange($event.target.value)"> Why the following does not debounce? onChange(val: string) { of(val) .pipe( debounceTime(300) ).subscribe(valx => { console.log(valx); }); } But this does: searchTerm$: Subject<string> = new Subject(); this.searchTerm$.pipe( debounceTime(300), ).subscribe(val => { console.log(val); }); onChange(val: string) { this.searchTerm$.next(val); } 回答1: This isn't because of of() . In your first example every time you call
