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

How do you do this???

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

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>");
  //option's value is the href
  //option's text is the text of link
  //append option to select

//Create button 
//Bind click to button
  //Go to select's location
//Modify CSS to hide links on small width and show button and select
  //Also hides select and button on larger width and show's links
//Deal with selected options depending on current page

Hey Theodore,

The challenge tells you it just wants you to use the function that goes over each of the links within "#menu" and pass in an anonymous function. So, all you gotta do is just that!

$("#menu a").each(function () {});

Thank you Marcus. Great answer . . .

I'm not going to automatically assume that's sarcasm, although the ellipsis at the end do give off the impression of that. The challenge is so straightforward you can't really go into more detail than that unless I explained that an anonymous function is one that doesn't have a name on it. So, it's just function () {}.

Marcus, I wasn't meaning to be sarcastic. I meant that your answer was exactly what I needed to allow me to continue. It worked, and I was able to go to the next challenge. Thank you for the help.

As I said, I didn't automatically assume it was, although it does give off the appearance of sarcasm. You're welcome.
