title: Javascript alert popup form
body: <p>i have search this whole site and google but cannot find it so, here goes!</p>
  
  <p>i would like a way to show a form when using alert.</p>
  
  <p>for example, when user click post, a dialog pop with asking user a few question like a html form and allow user to click submit or reset or cancel, without loading a new page.</p>
