debounce

问题 Background Assume we all know about the debounce function from lodash . If a user quickly input 1 , 12 , 123 , 1234 , it allows us to proceed an alert only once, with 1234 , after a certain delay time. This is quite used to reduce request amount, for optimization. Description For a normal input field, we can use that kind of debounce and it works. Problem : Once we add a setState inside the same callback with debounce , the debounce won't work as normal. Does anyone know the reason? import

问题 I'm using the Vuetify Autocomplete with remote data, and I would like to to throttle / debounce the API calls (wait 500 ms to call the API when the user is typing text in the autocomplete). How can I do that? I saw a Stack OverFlow post about the debounce-search attribute, but it didn't work for me, and I didn't see any Vuetify documentation on this attribute. 回答1: You could add debouncing to the function that makes the API calls. A debouncer could be implemented with setTimeout and

问题 Is there a way to do a leading debounce? The example on the recipes only shows a trailing debounce. So below is trailing debounce example where we delay the logic fro 500ms: import { call, cancel, fork, take, delay } from 'redux-saga/effects' function* handleInput(input) { // debounce by 500ms yield delay(500) ... } function* watchInput() { let task while (true) { const { input } = yield take('INPUT_CHANGED') if (task) { yield cancel(task) } task = yield fork(handleInput, input) } } where as

问题 Been looking for a debounce function or way to debounce in Jquery. The build up of animations can get super annoying. Heres the code: function fade() { $('.media').hide(); $('.media').fadeIn(2000); } var debounce = false; function colorChange() { if (debounce) return; debounce = true; $('.centered').mouseenter(function() { $('.centered').fadeTo('fast', .25); }); $('.centered').mouseleave(function() { $('.centered').fadeTo('fast', 1); }); } function colorChange2() { $('.centered2').mouseenter

问题 In my React Hooks app I need to let user type to an input field for 1000ms. When 1000ms expire an API request is sent with the input value. <input type='text' name='name' className='th-input-container__input' onChange={evt => testFunc2(evt.target.value)} /> The value is set in testFunc2(evt.target.value) : const testFunc2 = useCallback(debounce((text) => setNameFilter(text), 1000), []); Once nameFilter is set to a new value useEffect issues an API request since nameFilter is its dependency.

问题 I have a functional component built around the React Table component that uses the Apollo GraphQL client for server-side pagination and searching. I am trying to implement debouncing for the searching so that only one query is executed against the server once the user stops typing with that value. I have tried the lodash debounce and awesome debounce promise solutions but still a query gets executed against the server for every character typed in the search field. Here is my component (with

问题 I am trying to use Ben Alman's debounce code. I have the following code but I don't see anything executing at all. onChange() { var this_ = this if (this.autoRefreshOn) { Cowboy.debounce(function(e) { console.log("debounce worked"); this_.doSomethingFunction(); }, 250); } } This onChange() function is fired from multiselect boxes like this: <ss-multiselect-dropdown (ngModelChange)="onChange($event)"></ss-multiselect-dropdown> <ss-multiselect-dropdown (ngModelChange)="onChange($event)"></ss
