选择输入元素时如何显示数据？

Question

我希望在我的表格中输入员工时选择员工时显示数据，实际上我只能显示所有元素但是当员工被选中时没有，有人可以用if条件帮助我吗？

<div id="EmployeeView" class="tabcontent">
<div class="row" style="padding: 0px 0px 0px 15px;">
<tr>
    <td><input list="Assigment" required name="Assigment" class="list-assignment col-md-8" placeholder="Employee"style="border-radius: 5px;"> 
        <datalist id="Assigment">

            for (int w = 0; w < nameList.size(); w++) {

            <option value="<%=nameList.get(w).getAttUid()%>">

            out.println(nameList.get(w).getFullName());

            </option>

            }

        </datalist>
    </td>
</tr>
</div>
<br>
<div class="row" style="padding: 0px 0px 0px 15px;" style="display: block;">

<table>
 <tr>

    int z;
    int sizeView = empDetailsMap.size();
    Employee employeeView = new Employee();
    out.println("<tr><th>Task Name</th>");
    out.println("<th>Status</th>");
    out.println("<th>Estimated Time</th>");
    out.println("<th>Actual Time</th></tr>");
    for (Map.Entry<String, Employee> entry : empDetailsMap.entrySet()) {
        String key = entry.getKey();
        employee = entry.getValue();


        for (z = 0; z < employee.getTaskAssignment().getMinorTaskName().size(); z++) {
            out.println("<tr><td>" + employee.getTaskAssignment().getMinorTaskName().get(z) + "</td>" + "\n");                          
            out.println("<td>" + employee.getTaskAssignment().getTaskStatus().get(z) + "</td>" + "\n");
            out.println("<td>" + employee.getTaskAssignment().getEstTime().get(z) + "</td>" + "\n");    
            out.println("<td>" + employee.getTaskAssignment().getEstTime().get(z) + "</td></tr>" + "\n");
