title: pause function until enter key is pressed javascript
body: <p>new to javascript.  i know this might be really simple but I can't figure it out.  I want to execute a function. Pause in the middle of the function and wait for the user to hit “enter” key which will allow function to continue again (or will call another function to fire).</p>
  
  <pre><code>function appear()
  {
  document.getElementById("firstt").style.visibility="visible";
  //here is where I want the pause to happen until the user presses "enter" key
  //Below is what I want to happen after the "enter" key has been pressed.
  document.getElementById("startrouter").style.visibility="visible";
  
  
  }
  </code></pre>
