title: Disable button after submit with jQuery
body: <p>I know there are a lot of questions about it, but I tried several solutions, and nothing works.</p>
  
  <p>In my django app I have a form:</p>
  
  <pre><code>&lt;form method='post'&gt;
      &lt;button type='submit'&gt;Send&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I wan't to disable the button once the user has submitted the form. Using other questions, I tried several things, like:</p>
  
  <pre><code>&lt;button type='submit' onclick="this.disabled=true"&gt;Send&lt;/button&gt;
  </code></pre>
  
  <p>When I click, the button is disabled... but the form is not submitted. And for each try I had the same issue: either the button is disabled or the form is submitted. I can't find how to do both...</p>
  
  <p>I'm using Chrome. Any idea on why I have this problem?  Thank you for your help.</p>
