5秒后打开弹出窗口我在做什么错？

Question

I placed a popup on page load, but I would prefer to appear after 5 seconds. I inserted tie out code, but it is not working what am I doing wrong?

<script type="text/javascript">

        var link;
        var element;
                    t=setTimeout(openpopupFunction,5000);
        function openPopUp(url)
        {
            link = url;
            element = document.getElementById("background");
            element.style.display = "block";
            element = document.getElementById("popup");
            element.style.display = "block";

        }
</script>

You are using a different function name when you try to call it. Use:

var t = setTimeout(openPopUp, 5000);

You only need the variable t here if you need to stop the timeout.

Side note: You would normally declare the variables link and element inside the function so that they are local, not global variables. Try to keep as little as possible in the global scope, to minimise the risk of conflicts between scripts and with other things that are already in the global scope.
