Image Rotator in Javascript

Introduction

There are many ways to create an Image Rotator in JavaScript.I have written two simple examples of how to create an Image rotator in JavaScript.

My First Program

Step 1. First, we create an image(img1) with the help of <img> tag. and place it in the <body> tag.

<body onload="show()">
    <h3>Image Rotator in JavaScript</h3>
    <img id="img1" width="120px"/>
</body>

Note. Here, we call a js function(show()) on the onload event.

Step 2. Create a javascript function(show()) in the <head> tag.

<script language="javascript">
      function show() {
        document.getElementById('img1').src = 'images/img1-.jpg';
        setTimeout('show2()', 1000);
      }
      function show2() {
        document.getElementById('img1').src = 'images/img2-.jpg';
        setTimeout('show3()', 1000);
      }
      function show3() {
        document.getElementById('img1').src = 'images/img3-.jpg';
        setTimeout('show4()', 1000);
      }
      function show4() {
        document.getElementById('img1').src = 'images/img4-.jpg';
        setTimeout('show()', 1000);
      }
</script>

Output

Here, we get the ID of the image(img1) with the help of getElementById (The getElementById() method accesses the element with the specified id). and sets the source(src) of the img1. Here, we create many functions and call them with the help of the setTimeout Method of JavaScript. In my second Program, Here, we set the image based on the onmouseover event of the particular Table's Text and set the image and its description based on it.

Step 1. First, We create a table in the <body> tag and set an image(img1) and multiple <p> tags in the table rows.

<body onload="show()">
    <table style="border: 1px solid Black">
      <tr>
        <td>
          <table> 
            <tr>
              <td>
                <img id="img1" src="images/img1-.jpg" width="120px" />
              </td>
            </tr>
            <tr>
              <td>
                <p id="pmain"></p>
              </td>
            </tr>
          </table>
        </td>
        <td>
          <table style="width: 140px">
            <tr>
              <td
                id="td1"
                align="center"
                style="border: 1px solid Black"
                onmouseover="show1()"
                onmouseout="hide1()"
                <p id="p1">Image1</p>
              </td>
            </tr>
            <tr>
              <td
                id="td2"
                align="center"
                style="border: 1px solid Black"
                onmouseover="show2()"
                onmouseout="hide2()"
                <p id="p2">Image2</p>
              </td>
            </tr>
            <tr>
              <td
                id="td3"
                align="center"
                style="border: 1px solid Black"
                onmouseover="show3()"
                onmouseout="hide3()">
                <p id="p3">Image3</p>
              </td>
            </tr>
            <tr>
              <td
                id="td4"
                align="center"
                style="border: 1px solid Black"
                onmouseover="show4()"
                onmouseout="hide4()">
                <p id="p4">Image4</p>
              </td>
            </tr>
          </table>
        </td>
      </tr>
    </table>
</body>
