title: Javascript Injection with Xamarin forms WebView
body: <p><strong>I want to change the value of an element inside a Xamarin forms <code>WebView</code></strong></p>
  
  <p>I created a new project and added a <code>WebView</code> page that loads <a href="https://www.google.com/" rel="nofollow noreferrer">https://www.google.com/</a><br>
  I have used .Eval</p>
  
  <p><code>m_GoogleWebView.Eval("alert('coolness!');");</code></p>
  
  <p>This alerts fine for me. However if I try to access the dom at all, it just replaces the WebView with the text 'test text'</p>
  
  <pre><code>m_GoogleWebView.Eval("document.getElementById('lst-ib').value='test text';");
  </code></pre>
  
  <p>How should I manipulate elements from Xamarin Forms?</p>
