In this program I created object and instances of it and stored those instances in array. I am retrieving array index by getting the modulo of minutes with the length of the array. I am trying to display link in div tag and I should be able to see different link every minute. Upon clicking link it should show different url. and set the timer to run every minute. For that I have created setInterval(). but it doesn't seem to work. Can anyone help me?

code:

```
<!DOCTYPE html>
<html>
<head>
    <style>

    .myDiv{
        width: 750px;
        height: 150px;
        border: #CED8BC 3px solid;
        border-radius: 20px;
        position: absolute;
        top: 30%;
        left: 20%;
    }

    div p {
        text-align: center;
        font-family: monospace;
        font-size: 30px;
    }

    a{
        text-align: center;
        text-decoration: none;
        color: #3bb570;

    }   

    a:hover{
        color:#efa5db
    }

</style>
<title>lab15</title>

</head>
<body background="lab15_images/pink.jpg">
    <div class="myDiv" id="div">
        <p> Click on the link to see a website. </p>
        <!-- <p><b><a href="#" id="link">  </a></b></p> -->
        <p id="link">  </p>
    </div>

    <script>
        function site(the_url, website_name) {
            this.the_url = the_url;
            this.website_name = website_name;
        }

        var myWebsite = new site("http://www.cnn.com/", "CNN");
        var myWebsite2 = new site("http://www.bbc.com/news", "BBC");
        var myWebsite3 =  new site("http://www.foxnews.com/", "FOX NEWS");
        var myWebsite4 =  new site("http://abcnews.go.com/", "ABC NEWS");
        var myWebsite5 =  new site("https://www.cbsnews.com/", "CBS NEWS");

        var instances = new Array(myWebsite, myWebsite2, myWebsite3, myWebsite4, myWebsite5);

        setInterval(changeLink, 60000);

        function changeLink() {

            var n = new Date().getMinutes();
            var index = n % instances.length
            var site = instances[index] 
            var counter = 0;

            var ele = document.getElementbyId("link");
            ele.innerHTML = instances[counter];
            counter++;

            if(counter >= instances.length) {
                counter = 0;
            }

            var a = document.createElement('a');
            var myDiv = document.getElementbyId("div");
            a.href = site.the_url;
            a.innerHTML = site.website_name
            myDiv.appendChild(a);
            document.body.appendChild(myDiv);

        }

    </script>
</body>
