$('input[name="merchantIds"]').each(function(){
    $(this).click(function () {

        $('input[name="merchantIds"]:checked').each(function(i, o){
            chkStr += $(this).val()+",";
        });

            success: function(msg) {
                if (msg.success) {
                    var obj = msg.obj;
                    $("#shopIdsControl .checkboxSpan").hide();
                    $.each(obj, function(shopIndex, shop){
                        $("#shopIdsControl input[value='"+shop.id+"']").parents(".checkboxSpan").show();
                    });
