Is there any way to create prompt with two input fields?

This is not possible with an OS or native browser window popping up. You will have to create a custom overlay dialog.

I would advise using a library like jQuery UI to do this. You can then customize whatever is in the popup.

You can view a demo of the dialog here

Short of constructing your own using DOM methods and Input elements: No.

JavaScript Code

           <script>             $( "#create-user" )             .button()             .click(function() {             $( "#dialog-form" ).dialog( "open" );               });            });           </script>

Html Code:

          <div id="dialog-form" title="Create new user">          <p class="validateTips">All form fields are required.</p>          <form>         <fieldset>         <label for="name">Name</label>          <input type="text" name="name" id="name" class="text">          <label for="email">Email</label>         <input type="text" name="email" id="email" value="" class="text">         <label for="password">Password</label>          <input type="password" name="password" id="password" value="" class="text">        </fieldset>        </form>       </div>        <button id="create-user">Create new user</button>
