API

props

handler

Type: function
Required: true

The handler function to run after you scroll to the bottom of the list. It will also be invoked on component mounted and the mugen-scroll component is visible in viewport.

handleOnMount

Type: boolean
Default: true

Invoke the handler function on component mounted.

shouldHandle

Type: boolean
Default: true

Add an additional condition to check if it should invoke the handler function, for example you don't want it to be invoked again as it's loading.

threshold

Type: number
Default: 0

Set the ratio of the <mugen-scroll>'s height and width that needs to be visible for it to be considered in viewport. This defaults to 0, meaning any amount. A threshold of 0.5 or 1 will require that half or all, respectively, of the element's height and width need to be visible. threshold must be a number between 0 and 1

scrollContainer

Type: string

If the container of your list is scrollable, you can specific the reference ID of the container, so that we can detect the scroll event of this element instead of window.

<template>
  <div class="wrap"
    <!-- the container is scrollable here -->
    style="height: 200px; overflow: auto;"
    <!-- add the ref -->
    ref="wrap">
    <div class="list"><!-- your list --></div>
    <mugen-scroll
      <!-- pass the ref id -->
      scroll-container="wrap">
      Loading...
    </mugen-scroll>
  </div>
</template>
