jquery - Repeating functions -


i seem repeat alot of functions when coding simple, there better way of doing this?

  $('#bt1').click(function() {       $('#txt1').show();       $(this).css("background-image", "url(site_images/08/btn_over.png)");   });     $('#bt2').click(function() {       $('#txt2').show();       $(this).css("background-image", "url(site_images/08/btn_over.png)");   });     $('#bt3').click(function() {       $('#txt3').show();       $(this).css("background-image", "url(site_images/08/btn_over.png)");   });     $('#bt4').click(function() {       $('#txt4').show();       $(this).css("background-image", "url(site_images/08/btn_over.png)");   });

so i'm not repeating code?

give buttons class, such btn, , can like:-

$('.btn').click(function() {   $('#' + this.id.replace('bt', 'txt')).show();   $(this).css("background-image", "url(site_images/08/btn_over.png)");  });
