Javascript无法在浏览器中运行？ （Firefox，Chrome和Safari）

Question

http://pastebin.com/K2miHiAj

That's where the code is located ^

I use both Coda 2 and BBEdit to run the code on and test it, and it works perfectly fine on them! However, whenever I try a browser, the code never runs properly. For this assignment the code has to work on Firefox.

Answer 1

You've defined the function myFunction AFTER trying to attach it to the onclick , therefore the thing in onclick="myFunction()" is undefined .
Solution: seperate your JavaScript from your HTML.

// attach listener to window.load
window.addEventListener('load',function () {
    // attach listener to your button
    document.getElementById('clickme')
        .addEventListener('click',
                          myFunction,
                          false);
}, false);

Look at this fiddle .
