JS's function throttling and throttle and debounce detailed:Also realizes a function, may have the high efficiency, some efficiency is low, this phenomenon in the high energy dissipation execution process distinguishes is more obvious.A more common way to improve performance in this section, often called "function throttling," is described in code examples below.I. What is a function throttle:In the actual coding, MouseMove and resize are very frequen

Throttle The throttle here refers to the function throttling. In other words, the frequency controller of function calls is the continuous execution interval control. Main application scenarios include: 1. Move the mouse and move the mousemove event2. DOM element dynamic positioning, window object resize and scroll events Someone uses the above-mentioned event image as a machine gun scan. throttle is the trigger of the machine gun. If you don't trigger the trigger, it will always scan. The same

resizing n milliseconds to perform subsequent processing, while most of the other events need to perform subsequent processing at a certain frequency. There are two solutions to debounce and throttle in response to both of these requirements. Throttle and Debounce are two solutions to the mismatch between request and response speed. The difference lies in the choice of different strategies. Throttle perf

ThrottleThe throttle we're talking about here is the meaning of function throttling. Another popular point is the frequency controller of the function call, which is the continuous execution time interval control. The main application scenarios are as follows:1. Mouse movement, MouseMove eventDynamic positioning of 2.DOM elements, resize and scroll events for window objectsSome image of the image of the event described above as a machine gun fire, throttle is the trigger of machine guns, you do

First, prefaceThe following scenarios are often triggered by frequent events, so frequent DOM operations, resource loading, and other heavy behaviors can cause UI pauses and even browser crashes.1. Resize, scroll events for window objects2. MouseMove event when dragging3. MouseDown, KeyDown events in shooting games4. Text input, auto-complete KeyUp eventIn fact, for the Resize event of window, most of the actual demand is to stop changing the size of n milliseconds after the subsequent processin

Debounce, vue. jsdebounce Problem description In the search input box, subsequent operations, such as initiating an Http request, are performed only after the user stops entering the input. Those who have learned electronic circuits should be aware of the anti-shake button. The principle is the same: that is, this action is executed only after n milliseconds of the Call action. If this action is called again within n milliseconds, the execution time i

Throttle: Ignore all calls within a certain period of time. Debounce: If no call is made at a certain interval, we will introduce the Throttle amp; Debounce application. If you are interested, refer to the following: Throttle Ignoring all calls within a certain period of time is suitable for use when the frequency is high and the processing is heavy. The Code is as follows: Var throttle = function (fun

there are two requests, a request is a keyword, and a request is the AB keyword. The surface is ' A ' request sent out first, ' AB ' request sent out. If the after-issued ' AB ' request returns first, the ' A ' request returns, then the result of the ' a ' request will overwrite the result of the ' AB ' request. resulting in incorrect search results. Solve the problemThis problem can be solved by using the powerful Rxjava debounce operator.subsc

In JavaScript, Throttle, Debounce, and Immediate are regularly controlled. throttledebounce Preface We call these actions events and respond to callbacks ). A continuous event stream is called an event stream ). The speed at which these behaviors occur is not manually controlled. However, we can control when and how to activate the correct response. Some technologies provide us with precise control. Throttle In modern browsers, the frame rate of 60fps

can solve some problems, but also need to pay a high cost. In particular, the client and server models require the client to upgrade the hardware basically impossible.With limited resources, processing functions cannot respond to high-frequency calls in real time. Second, is it possible to respond only to part of the request? Dense requests under certain scenarios have strong homogeneity and continuity. For example, the trajectory parameter of the mouse movement. The more timely the response, t

Throttle Disregard for a certain period of time all the calls, suitable for the occurrence of relatively high frequency, the handling of heavier time to use. Copy Code code as follows: var throttle = function (func, threshold, Alt) { var last = Date.now (); Threshold = Threshold | | 100; return function () { var now = Date.now (); if (Now-last if (ALT) { Alt.apply (this, arguments); } Return } last = Now; Func.apply (this, arguments); }; };

example, when the user first enters the keyword ' AB ' This time there are two requests, one request is a keyword, and one request is the AB keyword. On the surface is ' A ' request to send out first, ' AB ' after the request sent out. If the ' AB ' request is sent back first and the ' a ' request is returned, the result of the ' a ' request will overwrite the result of the ' AB ' request. resulting in incorrect search results.
