Hi , I am implementing a number spinner which should take value like 1,2,3,4,5,6,7,8,9,10,20,30,40,50,75,100,100+
I am using jQuery UI to implement the spinner
I wanted to know is it even possible to display text values in the spinner…
I have been trying several diff variations of code… to do the job, but to no avail

here is one variation>>>


$(function(){
var ind=0;
var qty = Array("1", "2", "3" ,"4" ,"5" ,"6" ,"7","8","9","10","20","30","40","50","75","100","100+");
$('#spinner').spinner({step:1});
$('#spinner').on({"spin":function(e,ui){if(qty[ind+1] > $('#spinner').spinner("value"))
                                           {
                                                 if(ind<qty.length)
                                                             {$('#spinner').spinner("value",qty[++ind]);

                                                             }
                                                     else
                                                          {$('#spinner').spinner("value",qty[0]);
                                                             ind=0;
                                                           }
                                             }
                                        else if(qty[ind+1] < $('#spinner').spinner("value"))
                                                 {
                                                      if(ind > 0)
                                                         {
                                                          $('#spinner').spinner("value",qty[--ind]);
                                                          }
                                                       else
                                                         {
                                                           $('#spinner').spinner("value",qty[qty.length-1]);
                                                              ind=qty.length-1;
                                                         }
                                                 }
                                       }
                 });

});

As far as i can see in firebug , this code is changing value of the spinner but for only a split second…as soon as it executes the line

$(‘#spinner’).spinner(“value”,qty[++ind]);

the value changes back to normal spinner value

i have tried using ui.value = qty[++ind]

and $(this).val(qty[++ind])

can anyone tell me whats wrong with my code, or if I am doing it a wrong way, what is the right way to do this?

Thanks.
