Uncaught syntaxerror: missing ) after argument list

Question

Problem:

My code isn't running. In the console the error is “Uncaught SyntaxError: missing ) after argument list” but there are no missing ) I find.

Here is my code below:

var nav = document.getElementsByClassName('nav-coll');
for (var n = 0; n < button.length; n++) {
    nav[n].addEventListener('click',function(){
            console.log('haha');
        }
    }, false);
};

I’d be thankful to him if somebody pulls me up from here.

Thanks.

We should always keep a sharp eye on our details in the code. Even a single semicolon (;) does matter here a lot.

As I can see all your logic, declaration and iteration are fine except parenthesis. You put an extra parenthesis in your code after the line

​console.log('haha');

I’ve removed the extra parenthesis from your code. Now it should run error-free. Give it a try now.

var nav = document.getElementsByClassName('nav-coll');
for (var n = 0; n < button.length; n++) {
    nav[n].addEventListener('click',function(){
            console.log('haha');
    }, false);
};

Thanks.
