<template>
  <div class="iframe-container">
    <iframe id="iframeContainer" :src="iframeUrl" frameborder="0" />
  </div>
</template>
 

<script>
import { mapGetters } from 'vuex'

    iframeUrl: {
      type: String,
      default: ''
    }
  },
  data() {
    return {}
  },
  computed: {
    ...mapGetters([
      'sidebar'
    ])
  },
  watch: {
    'sidebar.opened': {
      handler: function() {
        this.initIframe()
      },
      immediate: true
    }
  },
  mounted() {
    this.initIframe()
 
    window.onresize = () => {
      this.initIframe()
    }

      iframeContainer.style.height = (Number(deviceHeight) - 110) + 'px'
