Introduction

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.
Tab1.gif
Step 1: First we create a table for the tabs.
  1. <table style="width: 239px" border="1">
  2. <tr>
  3. <td id="td1" >Tab1</td>
  4. <td id="td2>Tab2</td>
  5. <td id="td3>Tab3</td>
  6. <td id="td4">Tab4</td>
  7. </tr>
  8. </table>
After that we create four tables for different tabs:
  1. <table border="1">
  2. <td class="style2">
  3. <table id="Table1" border="1" >
  4. <tr><td class="style4">One</td></tr>
  5. <tr><td class="style4">Two</td></tr>
  6. <tr><td class="style4">Three</td></tr>
  7. </table>
  8. <table id="Table2" border="1" style="display:none;" >
  9. <tr><td class="style4"><a href="http://www.yahoo.com">Yahoo</a></td></tr>
  10. <tr><td class="style4"><a href="http://www.Google.com">Google</a></td></tr>
  12. </table>
  13. <table id="Table3" border="1" style="display:none;" >
  14. <tr><td class="style5">
  15. <img alt="" src="Image/168241_1780007696922_1141309985_2052634_3074841_n.jpg"
  16. style="height: 69px; width: 84px" /></td><td class="style4">1st </td></tr>
  17. <tr><td class="style5">
  18. <img alt="" src="Image/168488_1809301029237_1141309985_2105127_5934469_n.jpg"
  19. style="height: 58px; width: 85px" /></td><td class="style4">2nd</td></tr>
  20. <tr><td class="style5">
  21. <img alt="" src="Image/180540_1801174706084_1141309985_2089035_3914864_n.jpg"
  22. style="height: 50px; width: 82px" /></td><td class="style4">3rd</td></tr>
  23. </table>
  24. <table id="Table4" border="1" style="display:none;" >
  25. <tr><td class="style4">First Heading</td></tr>
  26. <tr><td class="style4">Second Heading</td></tr>
  27. <tr><td class="style4">Third Heading</td></tr>
  28. </table>
  29. </td></tr>
  30. </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).
  1. <td id="td1" onmouseover="Show1()" onmouseout ="Hide1()" class="style1">Tab1</td>
  2. <td id="td2" onmouseover="Show2()" onmouseout ="Hide2()" style="text-align: center"><b>Tab2</b></td>
  3. <td id="td3" onmouseover="Show3()" onmouseout ="Hide3()" class="style3">Tab3</td>
  4. <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.
  1. <script language="javascript" type="text/javascript">
  3. function Show1() {
  4. document.getElementById('Table1').style.display = 'Block';
  5. document.getElementById('Table2').style.display = 'None';
  6. document.getElementById('Table3').style.display = 'None';
  7. document.getElementById('Table4').style.display = 'None';
  8. document.getElementById('td1').style.backgroundColor = "Red";
  9. document.getElementById('td1').style.color = "White";
  11. }
  12. function Show2() {
  13. document.getElementById('Table1').style.display = 'None';
  14. document.getElementById('Table2').style.display = 'Block';
  15. document.getElementById('Table3').style.display = 'None';
  16. document.getElementById('Table4').style.display = 'None';
  17. document.getElementById('td2').style.backgroundColor = "Red";
  18. document.getElementById('td2').style.color = "White";
  20. }
  22. function Show4() {
  23. document.getElementById('Table1').style.display = 'None';
  24. document.getElementById('Table4').style.display = 'Block';
  25. document.getElementById('Table3').style.display = 'None';
  26. document.getElementById('Table2').style.display = 'None';
  27. document.getElementById('td4').style.backgroundColor = "Red";
  28. document.getElementById('td4').style.color = "White";
  30. }
  32. function Show3() {
  33. document.getElementById('Table1').style.display = 'None';
  34. document.getElementById('Table3').style.display = 'Block';
  35. document.getElementById('Table2').style.display = 'None';
  36. document.getElementById('Table4').style.display = 'None';
  37. document.getElementById('td3').style.backgroundColor = "Red";
  38. document.getElementById('td3').style.color = "White";
  40. }
  41. function Hide1() {
  42. document.getElementById('td1').style.backgroundColor = "White";
  43. document.getElementById('td1').style.color = "Black";
  45. }
  46. function Hide2() {
  47. document.getElementById('td2').style.backgroundColor = "White";
  48. document.getElementById('td2').style.color = "Black";
  50. }
  51. function Hide3() {
  52. document.getElementById('td3').style.backgroundColor = "White";
  53. document.getElementById('td3').style.color = "Black";
  55. }
  56. function Hide4() {
  57. document.getElementById('td4').style.backgroundColor = "White";
  58. document.getElementById('td4').style.color = "Black";
  60. }
  61. </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'.
