"loaded" doesn't stop loading #55

Closed DaveSanders closed 7 years ago

DaveSanders commented 7 years ago

v2.1.3 - for some reason the "loaded" emit isn't stopping it from continuing to load results down the page. I'm pretty sure this was working before, but I can't figure out why this is happening.

So, basically even though I haven't scrolled down, it keeps hitting my server and loading more results. Here's my onInfinite function:

onInfinite () {
        api.tracks.get(PAGE_AMOUNT, this.tracks.length, tr => {
          console.log(`TRACKS: ${this.tracks.length}`)

          if (tr.length > 0) {
            this.tracks = this.tracks.concat(tr)
            if (tr.length < PAGE_AMOUNT) {
              this.$refs.infiniteLoading.$emit('$InfiniteLoading:complete')
            } else {
              this.$refs.infiniteLoading.$emit('$InfiniteLoading:loaded')
            }
          } else {
            this.$refs.infiniteLoading.$emit('$InfiniteLoading:complete')
          }
        })
      }

My template:

<template>
  <div id="track-list">
    <TrackItem v-for='(track, index) in tracks' :track='track' :index="index" :key='track.id'/>
    <infinite-loading :on-infinite="onInfinite" ref="infiniteLoading" spinner="waveDots"></infinite-loading>
  </div>
</template>

I did put console logs in and it IS hitting that else where it sends the loaded emit. I also changed it to :complete and it stopped calling at that point in the code. So it is emitting, it just seems like its not caring - or for some reason it thinks that its scrolled down.

Anything I'm doing wrong? Or any ideas on how to debug it further?

There will be one more case that causes calling handler multiple time.

Here is my handler. I've added a filter statement to make sure there are no duplicated records.

infiniteHandler($state) {
  axios.get(api, {
    params: {
      page: this.page,
    },
  }).then(({ data }) => {
    if (data.hits.length) {
      this.page += 1;
      const newHits = data.hits.filter((hit) => 
        this.list.every((item) => item.id !== hit.id)
      );
      this.list.push(...newHits);
      $state.loaded();
    } else {
      $state.complete();
    }
  });
}

The problem comes when the data.hits.length > 0 and newHits = [], so the list never changes and it keeps calling the handler.
