Perform function every second

Perform function every second

I have created a page that grabs some data from a php page every second using a timer. However, I am pretty sure there is a way to make the code a lot shorter and neater, perhaps using a loop.

Here is the code

  2. <script type="text/javascript">

  4. $(document).ready(function() {
  5. var delay = 10 ;
  6. function countdown() {
  7. setTimeout(countdown, 1000) ;
  8. $('#countmesg').html("Ends in "  + delay  + " seconds.");
  9. delay --;

  11. if (delay == 10 ) {
  12. $.post('grab.php', {name: name}, function(data) {
  13. $('div#name-data').text(data);
  14. });
  15. }

  17. if (delay == 9 ) {
  18. $.post('grab.php', {name: name}, function(data) {
  19. $('div#name-data').text(data);
  20. });
  21. }

  23. if (delay == 8 ) {
  24. $.post('grab.php', {name: name}, function(data) {
  25. $('div#name-data').text(data);
  26. });
  27. }

  29. if (delay == 7 ) {
  30. $.post('grab.php', {name: name}, function(data) {
  31. $('div#name-data').text(data);
  32. });
  33. }

  35. if (delay == 6 ) {
  36. $.post('grab.php', {name: name}, function(data) {
  37. $('div#name-data').text(data);
  38. });
  39. }

  41. if (delay == 5 ) {
  42. $.post('grab.php', {name: name}, function(data) {
  43. $('div#name-data').text(data);
  44. });
  45. }

  47. if (delay == 4 ) {
  48. $.post('grab.php', {name: name}, function(data) {
  49. $('div#name-data').text(data);
  50. });
  51. }

  53. if (delay == 3 ) {
  54. $.post('grab.php', {name: name}, function(data) {
  55. $('div#name-data').text(data);
  56. });
  57. }

  59. if (delay == 2 ) {
  60. $.post('grab.php', {name: name}, function(data) {
  61. $('div#name-data').text(data);
  62. });
  63. }

  65. if (delay == 1 ) {
  66. $.post('grab.php', {name: name}, function(data) {
  67. $('div#name-data').text(data);
  68. });
  69. }




  74. if (delay < 0 ) {
  75. $('#countmesg').html("Auction ended.");
  76. delay = 0 ;
  77. }
  78. }
  79. countdown() ;
  80. });
  81. </script>
