debounce

问题 I'm trying to write a debounce function with typescript . I found an example of it in here. Code follows: export function debounce<Params extends any[]>( func: (...args: Params) => any, timeout: number, ): (...args: Params) => void { let timer: NodeJS.Timeout return (...args: Params) => { clearTimeout(timer) timer = setTimeout(() => { func(...args) }, timeout) } } Problem is: Function passed as a parameter is not getting called after the specified timeout I can't use lodash or any other

问题 it would be best to first look at my code: import React, { Component } from 'react'; import _ from 'lodash'; import Services from 'Services'; // Webservice calls export default class componentName extends Component { constructor(props) { super(props); this.state = { value: this.props.value || null } } onChange(value) { this.setState({ value }); // This doesn't call Services.setValue at all _.debounce(() => Services.setValue(value), 1000); } render() { return ( <div> <input onChange={(event,

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

问题 When user taps fast on the button the showDialog() method displays multiple times on top of each other, so when you dismiss it there is another one behind it. I am looking for a way to ignore the second tap for 1 second without using a handler or check the previous tap's time. //Button that opens a dialog button.setOnClickListener { showDialog() } I am looking for a solution using Kotlin coroutines or Kotlin flows for future implementations. 回答1: It's better to use a simple Flag for that

问题 I've read through the other posts but can't seem to fix mine. I'm new to VHDL so I'm sure it's a simple fix. In short, the button isn't debouncing. The code compiles and the bitstream programs. In the testbench, button presses work, but the output LEDs don't change. On the board, pressing a button makes random LEDs light up (I presume because of bouncing). According to the schematic the inputs are going through the debouncers. Can anyone identify the issue? And any other hints and tips are

问题 I have a very simple implementation of EasyMDE, which internally uses CodeMirror. So to check for change of input I need to do this as said in the EasyMDE docs. Which works fine and I can even detect for change and get the input value as well. The problem right now I facing is that, there is no debounce available in both EasyMDE/CodeMirror and I am syncing the input on change to my backend functionality. On every input event I cant afford to sync to backend as it is may become very expensive.

问题 In my template I have a field and two buttons: <div class="btn-plus" (click)="add(1)"> - </div> <div class="txt"> {{ myValue }} </div> <div class="btn-minus" (click)="add(-1)"> + </div> In my component .ts file I have: add(num) { this.myValue +=num; this.update(); // async function which will send PUT request } The this.update() function puts myValue in the proper field in a big JSON object and sends it to a server. Problem : When a user clicks 10x in a short period of time on button plus
