title: What is Vue way to access to data from methods?
body: <p>I have the following code:</p>
  
  <pre><code>{
    data: function ()  {
      return {
        questions: [],
        sendButtonDisable: false,
      }
    },
  
    methods: { 
      postQuestionsContent: function () {
        var that = this;
        that.sendButtonDisable = true;
      },
    },
  },
  </code></pre>
  
  <p>I need to change <code>sendButtonDisable</code> to true when <code>postQuestionsContent()</code> is called. I found only one way to do this; with <code>var that = this;</code>.</p>
  
  <p>Is there a better solution?</p>
