jQuery plugin in Vue component: Cannot pass value to prop

Question

I have added the jquery redactor plugin in a vue component. The plugin is working fine but I need to access the html so I can see it in Vue.

I have tried everything I can think of, methods, computed properties but I can't find a way. It's particularly tricky because Redactor adds new html into the dom, and I need to get the data from the added html.

Currently I am getting this error, this.$emit is not a function. I need to get the html value of .redactor-editor into the prop so it will be available in the vue data. The var textContent prints out correctly in console but I can't get that to show in the prop. Any help is greatly appreciated.

Component

<template>
  <div>
    <textarea class="form-control question-create-editor" id="question_description" placeholder="Go wild with all the details here - make image upload work" rows="3">
  </div>
</template>

<script>
  export default {
    props: ['redactorValue'],
    mounted: function(){
          $('#question-create-form .question-create-editor').redactor({
            imageUpload:'/urlGoesHereBro/',
            plugins: ['video', 'imagemanager', 'counter', 'limiter'],
            buttonsHide:['html', 'formatting', 'deleted', 'indent', 'outdent', 'alignment', 'horizontalrule']
          });
    },
    computed: {
      redactorValue: function(){
        $('#question-create-form .redactor-editor').on('keyup', function(){
          var textContent = $('#question-create-form .redactor-editor').html();
          console.log( 'textContent = ' + textContent );
          this.$emit('redactorValue', textContent);
        });
      }
    }
};

HTML

<vueredactor></vueredactor>

Answer

The this.$emit is not a function issue is because this is pointing to the window.

Also I moved the keyup definition into mounted.

export default {
    data(){
        return {
            redactorValue: null
        }
    },
    mounted: function(){
          $('#question-create-form .question-create-editor').redactor({
            imageUpload:'/urlGoesHereBro/',
            plugins: ['video', 'imagemanager', 'counter', 'limiter'],
            buttonsHide:['html', 'formatting', 'deleted', 'indent', 'outdent', 'alignment', 'horizontalrule']
          });

          $('#question-create-form .redactor-editor').on('keyup', function(){
              this.redactorValue = $('#question-create-form .redactor-editor').html();
          }.bind(this));
    }
};
