如何检查所有字段都填充了一些下拉列表中的第二级字段？

Question

任何人都知道如何检查所有字段都填充了某个下拉列表中的第二级字段？我尝试了一种来自互联网的方法，但它检查了所有字段，包括隐藏字段。如何查看可见的字段？

这是我的代码：

    所有表单字段都是必填字段。

<form id="FORM"  name="frmname" action="./../ScheduleServlet" method="post">
    <fieldset>
        <table style="width: 600px">
            <tr>
                <td style="width: 200px"><label for="jobName">Job Name</label></td>
                <td><input type="text" name="jobName" id="jobName"
                    class="text ui-widget-content ui-corner-all" /></td>
            </tr>


            <tr id="option0" >
            <td><label for="ProfileName">Profile Name</label></td>

                <td><select id="ProfileName" name="ProfileName">    
                <option >...Choose Profile Name...</option>
            <% 
            try{
                OverlayManager overlayMgr = new OverlayManager();
                ArrayList<OverlayDTO> currentList = overlayMgr.findAllOverlay();
                String name = "";
                for(int i = 0; i<currentList.size(); i++)
                {
                    name = currentList.get(i).getProfileName();
                    System.out.println("Here is name : "+name);
                        %>
                        <option ><%=name%></option>
                    <% }




            }        

                        catch(Exception e)

                        {
