Question

How to loop through a jquery each loop using filter :eq for an unknown range?

for example, I would like to loop through the following:

$("#list li:eq("+ i +")").each(function(i)
{
      i++;
});

This code does not work

Answer 1

$("#list li:eq("+ i +")").each(function(i)
{
      i++;
});

The above code has two obvious flaws:

1. you’re trying to use i before you assign it a value, and
2. $('#list li:eq(' + i + ')') will only ever return one result (the li that’s equal to whatever value i holds.

To iterate through the li elements, simply use:

$('#list li').each(function(i)
    {
        // do whatever you like in here.
    });

If you need to work only on elements that are equal to a particular value of i:

$('#list li').each(function(i)
    {
        if (i == 3){ // for example...
            // do whatever you like in here.
        }
    });

Or simply:

$('#list li').eq(3)
