ObjectiveAnti-shake, throttling is mainly used for frequent event triggering, such as mouse movement, changing window size. Lodash and other function libraries have corresponding APIs, _.debounce _.throttle .Core technology: Closures.Difference: Anti-shake, continuous trigger, first and last trigger valid Throttling, triggering only once (first time) over a period of time This article is t

destroyed. For example, it determines whether to destroy it by checking whether the memory usage increases. 2. Use Native JavaScript or Lodash Lodash simply overwrites some basic logic, rather than relying on the built-in AngularJS method to improve application performance. If your application does not contain Lodash, you may need to rewrite all the code in Nati

Now use

User on the slide load more time, because of the speed or the server returned data is slow, how to limit the slide to load only once paging data, how to implement the code Reply content: User on the slide load more time, because of the speed or the server returned data is slow, how to limit the slide to load only once paging data, how to implement the code Then request the data to be returned successfully and render to the page and then add 1 pages This is also the basic need to prevent

When a user slides on and loads more data, how can he restrict sliding multiple times to load paging data only once due to the speed of the network or the slow speed of data returned by the server, how does the code implement the code implementation when the user is loading more slide, and when the network speed or the server returns data slowly, how does the code limit the sliding multiple times to load the paging data only once? Reply content: When a user slides on and loads more data, how c

, second:2 } _ (obj). each (function (value, key) {return Obj[key] = value + 1; }); The map () method has the same function and parameters as the each () method, but it records the results returned by each iteration function to a new array and returns. 7. Function throttlingfunction throttling is the control of the execution frequency or spacing of a function (like the gate that controls the flow), underscore provides debounce () and

that the original program can run normally, suddenly become unable to work or a pile of bugs. NPM is also very sensitive to the order in which packages are introduced, such as executing the following command in an empty project NPM init-y npm install globule@0.1.0-s npm install babel-generator@6.19.0-s npm Install Babel-helper-define-map@6.18.0-s We have 3 packages installed here that depend on Lodash, but Globule relies on

);While (id> 0 ){If (id! = Gid ){ClearTimeout (id ); }Id --; } }})();After running the above code, it is actually invalid to set any setTimeout.The following is an example of the actual clearTimeout application. Some websites transmit users' input in the text box to the server via Ajax in real time. jQuery is written as follows.$ ('Textarea '). on ('keylow', ajaxAction );One major drawback of writing is that if you press keys consecutively, the keydown event is triggered con

the same function as the each () method, but it records the result returned by each iteration function to a new array and returns.5.7 Function throttlingfunction throttling is the control of a function's execution frequency or interval (just like the gate that controls the flow of water), underscore provides the debounce () and throttle () Two methods for function throttling.To describe these two methods more clearly, let's say we need to implement t

What is a dithering function? We need to understand this concept before learning JavaScript to shake the function. Many people confuse the concept of shaking with throttling, but these two concepts are well understood.The Debounce function is a function that can limit the frequency of the specified function firing. We can understand that to call the same function more than once, only to get the result of executing the function once, but again at some

This article mainly gives you a summary of the most basic JavaScript 7 functions, very practical, the need for small partners can refer to.
