title: Why is a script tag deleted automatically by Chrome?
body: <p>everyone.</p>
  
  <p>I don't use jQuery. I create a <code>script</code> tag and append it to <code>head</code> tag to get JSONP data. After JSONP callback function is executed, the <code>script</code> tag which is just added to <code>head</code> tag by me is automatically deleted by browser (Chrome). Why is the script tag deleted automatically by Chrome? I don't write any codes to delete this <code>script</code> tag.</p>
  
  <p>Thank you.</p>
