nested createefect do recrire

我不确定，如果我正确地复制了我的问题，但是这里是：

在渲染信号上，我有某种形式的对象创建会导致更多取决于更新信号的创建效果。但是某种程度上，范围被处置了，在创建时间只会发射一次。即使我提到了这些对象，我如何确保嵌套的createefect继续射击？

import { render } from 'solid-js/web';
import { on, createSignal, createEffect } from 'solid-js'

function HelloWorld() {

  let [render, setRender] = createSignal(undefined, { equals: false })

  let [update, setUpdate] = createSignal(undefined, { equals: false })
let i = 0

  createEffect(on(render, () => {
    if (i++ === 1) {
      createEffect(on(update, () => {
        console.log('inside')
      }))
    }
  }))

  createEffect(on(update, () => {
    console.log('regular', i)
  }))

 setInterval(() => {
   setUpdate();
    setRender();
  })
  return <div>Hello World!</div>;
}

render(() => <HelloWorld />, document.getElementById('app'))

我想要常规和内部在每个间隔上日志。

I am not sure, if I have correctly reproduced my problem but here it is:

On render signal, I have some sort of object creation that leads to more create effects that depend on update signal. But somehow the scope gets disposed and it only fires once at creation time. Even though I have references to these objects, how can I make sure nested createEffect keeps firing?

import { render } from 'solid-js/web';
import { on, createSignal, createEffect } from 'solid-js'

function HelloWorld() {

  let [render, setRender] = createSignal(undefined, { equals: false })

  let [update, setUpdate] = createSignal(undefined, { equals: false })
let i = 0

  createEffect(on(render, () => {
    if (i++ === 1) {
      createEffect(on(update, () => {
        console.log('inside')
      }))
    }
  }))

  createEffect(on(update, () => {
    console.log('regular', i)
  }))

 setInterval(() => {
   setUpdate();
    setRender();
  })
  return <div>Hello World!</div>;
}

render(() => <HelloWorld />, document.getElementById('app'))

I want regular and inside logs on every interval.

您可以使用creatoroot覆盖嵌套createefect的根。否则，它将被处置在“父”效果的每个重播上。

createEffect(() => {
   createRoot(dispose => {
      // effect will be disposed only when
      // the dispose() fn get's called
      createEffect(() => {...})
   })
})

You can use createRoot to overwrite the root of the nested createEffect. Otherwise it will be disposed on each rerun of the "parent" effect.

createEffect(() => {
   createRoot(dispose => {
      // effect will be disposed only when
      // the dispose() fn get's called
      createEffect(() => {...})
   })
})
