title: Use textarea input in JavaScript
body: <p>I'm trying to create a script that uses the input.</p>
  <pre><code>&lt;textarea id=&quot;textareabox&quot; name=&quot;textarea1&quot; placeholder=&quot;Start here...&quot;&gt;&lt;/textarea&gt;
  
  function hintbutton4() {
      document.getElementById(&quot;textareabox&quot;).innerHTML = 'ID=textareabox';
  }
  </code></pre>
  <p>I've got this, but I don't know how to grab the text as input...
  How can I do it? What should I search for?</p>
  <p>I want the input from the text area used in the script in the last part 'ID=textareabox'. That's all.</p>
