JavaScript jQuery Basics (2014) Creating a Mobile Drop Down Menu Using change()

Oops! Looks like task 1 is no longer passing...

I'm not sure why my code is no longer passing, All I had to do was removed the line of code that appends the button to the select element and change the click event to change...

Can anyone see why this may be happening?

js/app.js
//Problem: It look gross in smaller browser widths and small devices
//Solution: To hide the text links and swap them out with a more appropriate navigation

//Create a select and append to #menu
var $select = $("<select></select>");
$("#menu").append($select);

//Cycle over menu links
$("#menu a").each(function(){
  var $anchor = $(this);
  //Create an option
  var $option = $("<option></option>");

  //Deal with selected options depending on current page
  if($anchor.parent().hasClass("selected")) {
    $option.prop("selected", true);
  }
  //option's value is the href
  $option.val($anchor.attr("href"));
  //option's text is the text of link
  $option.text($anchor.text());
  //append option to select
  $select.append($option);
});
//Create button 
var $button = $("<button>Go</button>");
//Bind click to button
$button.change(function() {
  // Go to select's location
  window.location = $select.val();
});

Hey Karl,

Task 2 asked you to do this:

"Now modify the $button click code so it now performs the redirect when the $select is changed."

All you have to do is bind that existing change event to $select instead of $button. Like so:

$select.change(function(){
  //Go to select's location
  window.location = $select.val();
});

Looks like you've taken out the button create event altogether. You still need to create a button, just not append it to the #menu div. By not appending it, it will float up to the side of the select menu. Just remove the .append method and remove the parentheses from the button variable.
