how to keep track of a previous loop count using jquery?

put the variable outside the each or as global variable :

var loopCount = 0;
$("#list li").filter:gt('+ variable+').each(function(
{
       if(start > finish)
       {
            loopCount = loopCount + 1;
            $('#list2 li').append('<li>' + variable + '</li>');
       }

}))

Select allOpen in new window

or :

var loopCount = 0;
var loopCount = 0;
$(document).ready(function() {

$("#list li").filter:gt('+ variable+').each(function(
{
       if(start > finish)
       {
            loopCount = loopCount + 1;
            $('#list2 li').append('<li>' + variable + '</li>');
       }

}))

})

Select allOpen in new window

but how do I get the previous loop count in a current loop?

it's loopCount value

Let say for example, I have the following code

$("#click").click(function(
{
      var loopCount = 0;

       $("#list li").filter:gt('+ variable+').each(function(
       {
             if(start > finish)
            {
                  loopCount = loopCount + 1;
                 $('#list2 li').append('<li>' + variable + '</li>');
             }
          });
});

During each click of button, I want the loopCount to start at zero and count up. Upon additional clicks, I need to know what was the previous loopCount.

Thanks leakim but I wondering how to get lastLoopCountValue to read null during the first iteration of the loop.

var lastLoopCountValue = null;
$(document).ready(function() {

$("#click").click(function(
{
      var loopCount = 0;

       $("#list li").filter:gt('+ variable+').each(function(
       {
             if(start > finish)
            {
                  loopCount = loopCount + 1;
                 $('#list2 li').append('<li>' + variable + '</li>');
             }else
             {
                  alert(lastLoopCountValue); // its not reading a null value during the first iteration of the loop, which what I was expecting.
                  alert(loopCount);
             }
          });
       lastLoopCountValue = loopCount;
});

Put the alert before if(start > finish)

no?
