How do I skip the first iteration of an $.each()?

Question

I have a JSON list that I want to iterate over, but skip the first entry, like thus:

$.each(
    data.collection,
    function() { DoStuffButOnlyIfNotTheFirstOne(); }
);

Any ideas?

Answer 1

Is this good enough?

$.each(
    data.collection,
    function(i) {
        if (i > 0)
            DoStuff();
    }
);

Answer 2

$.each(
    data.collection,
    function(i) { if (i>0) DoStuffButOnlyIfNotTheFirstOne(); }
);

Answer 3

$.each(
    data.collection,
    function(i) {
        if(i)
            DoStuffButOnlyIfNotTheFirstOne();
    }
);

or, probably more efficiently:

$.each(
    data.collection.slice(1),
    function() {
        DoStuff();
    }
);

Answer 4

You can use the good old firstFlag approach:

var firstFlag = true;
$.each(
data.collection,
  function() { 
    if(!firstFlag) DoStuffButOnlyIfNotTheFirstOne(); 
    firstFlag = false;
}

But instead, I'd recommend that you filter your data collection first to remove the first item using a selector.
