Function interception in Vue is a technique used to limit the number of times a function is called within a specified time period and prevent performance problems. The implementation method is: import the lodash library: import { debounce } from 'lodash'; Use the debounce function to create an intercept function: const debouncedFunction = debounce(() => { / Logical/ }, 500); call the intercept function, and the control function is called at most once within 500 milliseconds.
Function intercept in Vue
What is function intercept?
Function interception is a technique that limits the number of times a function is called within a specified time period. This is very useful to prevent performance problems caused by frequent event triggering.
How to use function intercept in Vue?
In Vue, third-party libraries such as lodash can be used to implement function interception. Here is how to use the debounce function in lodash for function intercept:
<code class="javascript">import { debounce } from 'lodash'; // 創(chuàng)建一個截流后的函數(shù)const debouncedFunction = debounce(() => { // 在此處執(zhí)行你的邏輯}, 500); // 在需要時調(diào)用截流后的函數(shù)this.debouncedFunction();</code>
Parameter description:
- Function: The function to be intercepted.
- Waiting time: Controls the number of milliseconds when the function is called within a specified time.
effect:
When debouncedFunction is called, it will be called at most once in 500 milliseconds. If it is triggered multiple times in 500 milliseconds, only the last trigger will be executed.
Other options:
- **
leading：**布爾值，表示是否在等待時間開始時執(zhí)行函數(shù)。（默認(rèn)為false`) - **
trailing：**布爾值，表示是否在等待時間結(jié)束時執(zhí)行函數(shù)。（默認(rèn)為true`)
Notice:
- Make sure the lodash library is imported correctly in the Vue instance.
- When using the
lodashfunction, you need to install it in the component.
