codepen doesn’t like my js?

Why isn’t codepen using my js? http://codepen.io/MattSanford/pen/LxKea

You haven’t selected a library when you click the cog at the top-right of the JavaScript box? Is this right?

[matt_sanford]

I tried selecting a library but it didn’t affect anything.

var displayMain = function()
{
document.getElementById(“main”).style.display=”block”;
alert(‘js is loaded’)
}();

[JoniGiuro]

you need to add “()” at the end of the function if you want to run it whenever the browser sees it.

function funcitonName(){
//do your magic here
}();

He doesn’t want it to run on load, he wants it to run on click.

If you want to call the function from the HTML you need to store it as a variable, like so:

displayMain = function () {

document.getElementById(“main”).style.display=”block”;

}

That got it working for me.

@tbwii Thanks! is this just a codepen issue? Because it works just fine on my development page, prior to your solution.

@matt_sanford I think it might be an iframe issue – I have had similar things happen with jsFiddle. Chris could say for sure though.
