Jquery Code to show link while checkbox is checked on initial page load

I have a following piece of code which works fine, when i check or uncheck the checkbox, but when i initially loads my page and some of my checkboxes are already checked, i want to show the div box to be visible but the code is not doing so, am i missing anything

please guide through the following code

Thanks

$(document).ready(function() {
    //check the state of the checkox
    $(".showinvoice").is(':checked') {
        var stats = $(this).attr('data-id');
        $("#"+stats).css('display','block');
    }
    //check the code only when the click button is triggered    
    $(".showinvoice").click(function(e) {
        var getStudent = $(this).attr('data-id');
        if ($(this).is(':checked')) {
            $("#"+getStudent).css('display','block');
        } else {
            $("#"+getStudent).css('display','none');
        }
    });
});
