if the data is not reactive

Here is a snippet of my Vue component code highlighting a specific issue:

<template>
    <span splitpanes-default="70">
      Details Pane
            <uploader v-if="isUpload" class="uploader-example">
                <uploader-unsupport></uploader-unsupport>
                <uploader-drop>
                    <p>Drop files here to upload or</p>
                    <uploader-btn>select files</uploader-btn>
                    <uploader-btn :directory="true">select folder</uploader-btn>
                </uploader-drop>
                <uploader-list></uploader-list>
            </uploader>
    </span>
</template>

<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
import uploader from 'vue-simple-uploader';

Vue.use(uploader);

@Component()
export default class In extends Vue {

  public isUpload: boolean = false;

  public upload() {
      this.isUpload = true;
  }

 }
</script>

After calling the upload method (for example, on a button click), the "isUpload" property is correctly set to true, but the uploader component does not display.

It appears that the property is not reactive. What steps should I take to ensure reactivity?

Answer №1

Consider implementing the :key="" attribute on that specific component

<template>
    <span splitpanes-default="70">
      Details Pane
        <span v-if="isUpload">
            <uploader :key="uploaderKey" class="uploader-example">
                <uploader-unsupport></uploader-unsupport>
                <uploader-drop>
                    <p>Drop files here to upload or</p>
                    <uploader-btn>select files</uploader-btn>
                    <uploader-btn :directory="true">select folder</uploader-btn>
                </uploader-drop>
                <uploader-list></uploader-list>
            </uploader>
        </span>
    </span>
</template>

<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
import uploader from 'vue-simple-uploader';

Vue.use(uploader);

@Component()
export default class In extends Vue {
  uploaderKey = 0;
  public isUpload: boolean = false;


  public upload() {
      this.uploaderKey = this.uploaderKey + 1;
      this.isUpload = true;
  }

 }
</script>

Answer №2

It turned out that the issue stemmed from the splitpanes component (the outer part of which I didn't originally include in my question because I believed it wasn't relevant).

Therefore, the splitpane with the property "watch-slots" must be present to ensure that the inner content is fully reactive.
