title: What is the use of target attribute in HTML form tag?
body: <p>While I was implementing a file upload progress bar in PHP, I saw this target attribute in <code>form</code> tag. The code was like this:</p>
  
  <pre><code>&lt;form action="&lt;?php echo $_SERVER["PHP_SELF"]; ?&gt;" 
        method="POST" id="myForm" 
        enctype="multipart/form-data" 
        target="hidden_iframe"&gt;
  </code></pre>
  
  <p>What is the use of this <code>target attribute</code> here?</p>
  
  <p>Actually, after submitting this form data (file) we track the upload progress from another page say <code>upload.php</code>. Could we implement this without the target attribute?</p>
