Why don't I see anything until after I quit?

Hey Matt,

Are you talking about quitting Workspaces or Treehouse.

Changes you make in Workspaces, do NOT auto-refresh in the browser. So, after every change, you will need to refresh the browser window, and sometimes even clear the cache.

Personally, I don't use Workspaces, but my suggestion is after every 'view,' close the tab the preview is in, and this way when you re-open a preview, it is (usually) a fresh one.

Hey Matt,

The way you've constructed your if statement is causing the loop to continue iterating, even after a decision other than quit is made.

By adding break statements to each of the decisions, the loop will stop and the print statements will show as desired. If you wanted the prompt to reappear, you would have to trigger it again with another line of code, but the code below will solve the current problem and prevent the behavior you're having trouble with at the moment.

Here's the modified code I used:

var inStock = [ 'apples', 'eggs', 'milk', 'cookies', 'cheese', 'bread', 'lettuce', 'carrot', 'broccoli', 'pizza', 'potato', 'crackers', 'onion', 'tofu', 'frozen dinner', 'cucumber'];
            var search;

            function print(message) {
              document.write( '<p>' + message + '</p>');
            }

            while(true){
              search = prompt("Search for a product in our store. Type 'list' to show all of the produce and 'quit' to exit");
              search = search.toLowerCase();
              if(search === 'quit'){
                break;
              }else if (search === 'list') {
                print(inStock.join(', '));
                break;
              }else{
                if(inStock.indexOf(search) > -1){
                  print('Yes, we have ' + search + ' in the store.');
                  break;
                } else {
                  print(search + ' is not in stock.');
                  break;
                }
              }
            }

Good luck with the course!

If you have this problem again you can go to the console and usually it will say where the problem is.

When you open the Workspace for this video, you'll notice that Dave posted a comment about this problem:

"/* Important note The behavior of most browsers has changed since this video was shot, so you won't see the same thing as I demonstrate in the video. In the video, you'll see that my script is able to print out to the browser using document.write( ) while inside a loop.

Most browsers no longer do that: they wait until the loop finishes and then they print to the window. So, you'll see a blank page until you type quit in the prompt window — then you'll see all the output printed to the screen.

Sorry for the confusion, and we'll update the video soon. */"

Now, to solve this problem, replace all instances of "print" with "alert" and you'll see your list as well as the other messages.

Example:

From

print( instock.join(', '));

To

alert( instock.join(', '));
