I'm hoping someone can find what my issue is. my script only fires when scrolled down... I need that functionality. What it doesn't do is fire on page load too which I need it to do initially. So it loads the content first, then I can scroll down the page for more new content. 

I tried putting the ajax inside a function with the function name outside and it still didn't fire.

```
$(document).ready(function() {
    $(window).scroll(function() {
        if ($(window).scrollTop() >= $(document).height() - $(window).height() - 100) {
            flag = true;
            first = $('#first').val();
            limit = $('#limit').val();
            no_data = true;
            if (flag && no_data) {
                flag = false;
                $('#loadmoreajaxloader').show();
                $.ajax({
                    url: "commentedoncontent.php",
                    dataType: "json",
                    method: "POST",
                    cache: false,
                    data: {
                        start: first,
                        limit: limit
                    },
                    success: function(data) {
                        flag = true;
                        $('#loadmoreajaxloader').hide();
                        if (data.count > 0) {
                            first = parseInt($('#first').val());
                            limit = parseInt($('#limit').val());
                            $('#first').val(first + limit);
                            $.each(data.posts, function(i, response) {
                                //post content here
                            });
                        } else {
                            alert('No more data to show');
                            no_data = false;
                        }
                    },
                    error: function(xhr, ajaxOptions, thrownError) {
                        alert(xhr.status);
                        flag = true;
                        no_data = false;
                    }
                });
            }
        }
    });
});
