Here we create a simple tab control in JavaScript. In this case when we mouse over the tab it activates and we are able to see the contents.

Step 1: First we create a table for the tabs.

<table style="width: 239px" border="1">
<tr>
<td id="td1" >Tab1</td>
<td id="td2>Tab2</td>
<td id="td3>Tab3</td>
<td id="td4">Tab4</td>
</tr>
</table>

After that we create four tables for different tabs:

<table border="1">
<td class="style2">
<table id="Table1" border="1" >
<tr><td class="style4">One</td></tr>
<tr><td class="style4">Two</td></tr>
<tr><td class="style4">Three</td></tr>
</table>
<table id="Table2" border="1" style="display:none;" >
<tr><td class="style4"><a href="http://www.yahoo.com">Yahoo</a></td></tr>
<tr><td class="style4"><a href="http://www.Google.com">Google</a></td></tr>

</table>
<table id="Table3" border="1" style="display:none;" >
<tr><td class="style5">
<img alt="" src="Image/168241_1780007696922_1141309985_2052634_3074841_n.jpg"
style="height: 69px; width: 84px" /></td><td class="style4">1st </td></tr>
<tr><td class="style5">
<img alt="" src="Image/168488_1809301029237_1141309985_2105127_5934469_n.jpg"
style="height: 58px; width: 85px" /></td><td class="style4">2nd</td></tr>
<tr><td class="style5">
<img alt="" src="Image/180540_1801174706084_1141309985_2089035_3914864_n.jpg"
style="height: 50px; width: 82px" /></td><td class="style4">3rd</td></tr>
</table>
<table id="Table4" border="1" style="display:none;" >
<tr><td class="style4">First Heading</td></tr>
<tr><td class="style4">Second Heading</td></tr>
<tr><td class="style4">Third Heading</td></tr>
</table>
</td></tr>
</table>

Note: Here we take an Image folder to store our images.

Step 2: Now we can write the JavaScript functions. We write it on the tabs (td elements).

<td id="td1" onmouseover="Show1()" onmouseout ="Hide1()" class="style1">Tab1</td>
<td id="td2" onmouseover="Show2()" onmouseout ="Hide2()" style="text-align: center"><b>Tab2</b></td>
<td id="td3" onmouseover="Show3()" onmouseout ="Hide3()" class="style3">Tab3</td>
<td id="td4" onmouseover="Show4()" onmouseout ="Hide4()" style="text-align: center"><b>Tab4</b></td>

Show1(): Shows the particular tab content and changes the color of the tab.

Hide1(): Activates on the onmouseout event; sets the default color of each tab.

<script language="javascript" type="text/javascript">

function Show1() {
            document.getElementById('Table1').style.display = 'Block';
            document.getElementById('Table2').style.display = 'None';
            document.getElementById('Table3').style.display = 'None';
            document.getElementById('Table4').style.display = 'None';
            document.getElementById('td1').style.backgroundColor = "Red";
            document.getElementById('td1').style.color = "White";

        }
        function Show2() {
            document.getElementById('Table1').style.display = 'None';
            document.getElementById('Table2').style.display = 'Block';
            document.getElementById('Table3').style.display = 'None';
            document.getElementById('Table4').style.display = 'None';
            document.getElementById('td2').style.backgroundColor = "Red";
            document.getElementById('td2').style.color = "White";

}

        function Show4() {
            document.getElementById('Table1').style.display = 'None';
            document.getElementById('Table4').style.display = 'Block';
            document.getElementById('Table3').style.display = 'None';
            document.getElementById('Table2').style.display = 'None';
            document.getElementById('td4').style.backgroundColor = "Red";
            document.getElementById('td4').style.color = "White";

}

        function Show3() {
            document.getElementById('Table1').style.display = 'None';
            document.getElementById('Table3').style.display = 'Block';
            document.getElementById('Table2').style.display = 'None';
            document.getElementById('Table4').style.display = 'None';
            document.getElementById('td3').style.backgroundColor = "Red";
            document.getElementById('td3').style.color = "White";

        }
        function Hide1() {
            document.getElementById('td1').style.backgroundColor = "White";
            document.getElementById('td1').style.color = "Black";

        }
        function Hide2() {
            document.getElementById('td2').style.backgroundColor = "White";
            document.getElementById('td2').style.color = "Black";

        }
        function Hide3() {
            document.getElementById('td3').style.backgroundColor = "White";
            document.getElementById('td3').style.color = "Black";

        }
        function Hide4() {
            document.getElementById('td4').style.backgroundColor = "White";
            document.getElementById('td4').style.color = "Black";

}
</script>

Note: Here we set the display property. It displays the table according to the Tab. At this time we set the display property of the other table to 'None'.

Complete Program:

<head runat="server">
<title></title>
<script language="javascript" type="text/javascript">

function Show1() {
document.getElementById('Table1').style.display = 'Block';
document.getElementById('Table2').style.display = 'None';
document.getElementById('Table3').style.display = 'None';
document.getElementById('Table4').style.display = 'None';
document.getElementById('td1').style.backgroundColor = "Red";
document.getElementById('td1').style.color = "White";

}
function Show2() {
document.getElementById('Table1').style.display = 'None';
document.getElementById('Table2').style.display = 'Block';
document.getElementById('Table3').style.display = 'None';
document.getElementById('Table4').style.display = 'None';
document.getElementById('td2').style.backgroundColor = "Red";
document.getElementById('td2').style.color = "White";

}

function Show4() {
document.getElementById('Table1').style.display = 'None';
document.getElementById('Table4').style.display = 'Block';
document.getElementById('Table3').style.display = 'None';

document.getElementById('td3').style.color = "White";

}
function Hide1() {
document.getElementById('td1').style.backgroundColor = "White";
document.getElementById('td1').style.color = "Black";

}
function Hide2() {
document.getElementById('td2').style.backgroundColor = "White";
document.getElementById('td2').style.color = "Black";

}
function Hide3() {
document.getElementById('td3').style.backgroundColor = "White";
document.getElementById('td3').style.color = "Black";

}
function Hide4() {
document.getElementById('td4').style.backgroundColor = "White";
document.getElementById('td4').style.color = "Black";

}
