Challenge - Student records - Final Step - stuck

Hey guys,

I've messed something up in the challenge, which took me a bit longer than I've expected... but it was a cool refresher of all the stuff covered earlier on.

Here's the issue: I only see the records after closing the prompt window

Here's the code:

var message = " "; var searchInput = " ";

function print(message) { var outputDiv = document.getElementById("output"); outputDiv.innerHTML = message; }

function studentReport(student) { var report = '<h2>' + 'Student: ' + students[i].name + '</h2>'; report += '<p>' + 'Track: ' + students[i].track + '</p>'; report += '<p>' + 'Achievements: ' + students[i].achievements + '</p>'; report += '<p>' + 'Points: ' + students[i].points + '</p>'; return report; }

while (true) { searchInput = prompt("Enter the name of the student you want to stalk"); if (searchInput.toLowerCase() === "quit" || searchInput === null) { break; } for(var i = 0; i < students.length; i++) { student = students[i] if (student.name === searchInput) { message = studentReport(searchInput); print(message); } } }

Frankly I just want to move on, tried to figure out what I've messed up but it's taking too long, seriously. If you can take a look and let me know, that would be awesome.

If you're seeing the records when you close the prompt window, I think you're experiencing the problem Dave mentions in the Teacher's Notes for the video:

Important Update

Since this video was shot, the behavior of most browsers has changed, 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.

If that isn't what you're experiencing, I'm happy to take a look at your code if you format it with the Markdown Cheatsheet or take a snapshot of your workspace! Let me know!
