前导:false
用法
js
import { refThrottled } from '@vueuse/core'
import { shallowRef } from 'vue'
const input = shallowRef('')
const throttled = refThrottled(input, 1000)
尾随
如果您不想监听尾随更改,请将第三个参数设置为 false
(默认为 true
)
js
import { refThrottled } from '@vueuse/core'
import { shallowRef } from 'vue'
const input = shallowRef('')
const throttled = refThrottled(input, 1000, false)
前导
允许立即调用回调(在 ms
超时的前导边缘)。如果您不想要此行为,请将第四个参数设置为 false
(默认为 true
)
js
import { refThrottled } from '@vueuse/core'
import { shallowRef } from 'vue'
const input = shallowRef('')
const throttled = refThrottled(input, 1000, undefined, false)

类型声明
typescript
/**
* Throttle execution of a function. Especially useful for rate limiting
* execution of handlers on events like resize and scroll.
*
* @param value Ref value to be watched with throttle effect
* @param delay A zero-or-greater delay in milliseconds. For event callbacks, values around 100 or 250 (or even higher) are most useful.
* @param [trailing] if true, update the value again after the delay time is up
* @param [leading] if true, update the value on the leading edge of the ms timeout
*/

value: Ref<T>,
