Question

我想在点击它时显示Francis的ID。同样在数据库中有一个员工姓名和ID列表。所以，如果我点击Francis或Ivann。在文本框（箭头）中，它将显示仅在员工姓名中指定的他/她的ID。 :)

这里也是我的代码。

    if($_POST['id']!=null && $_POST['en']!=null && $_POST['date']!=null && $_POST['dp']!=null && $_POST['deduc']!=null){
       $stmt = $mysqli->prepare("INSERT INTO personal(id_personal,name,date,datepaid,deduction) VALUES (?,?,?,?,?)");
       $stmt->bind_param('sssss', $id, $en, $date, $dp, $deduc);

       $id = $_POST['id'];
       $en = $_POST['en'];
       $date = $_POST['date'];
       $dp = $_POST['dp'];
       $deduc = $_POST['deduc'];

您可以直接在员工选择框的选项中构建这种功能（顺便说一下，您的代码中有两个关闭的选择标记）。无论如何，为此，您可以利用HTML5 data属性，如下所示：

    <select class="form-control" id="en" name="en">
        <option>Choose</option>
        <?php
            include("alqdb.php");

            // ALSO ADD THE ID COLUMN TO YOUR SELECT QUERY SO YOU HAVE IT AVAILABLE TO YOU.
            $result =   mysqli_query($con, "SELECT EmpFName, id FROM employee");

            while($row  = mysqli_fetch_assoc($result)){
                // YOUR OPTION SHOULD HAVE A VALUE ATTRIBUTE IF YOU WISH TO SAVE THE FORM.
                // CHANGE $row["id"] TO THE APPROPRIATE NAME OF THE FIELD
                // CORRESPONDING TO EMPLOYEE ID.
                echo "<option value='{$row["EmpFName"]}' data-emp-id='{$row["id"]}'>";
                echo $row["EmpFName"] . "</option>";
            }
        ?>
    </select>

然后在Javascript（这里使用的JQuery）中：

    <script type="text/javascript" src="js/jquery.js"></script>
    <script language="javascript">
        (function($) {
            $(document).ready(function(){
                var empName = $("#en");
                var empID   = $("#id");

                empName.on("change", function(evt){
                    var eN  = $(this);          
                    var eID = eN.children('option:selected').attr("data-emp-id");
                    empID.val(eID);
                });

                $("#amnt, #sal").keyup(function() {
                    $("#deduc").val(($("#sal").val() - $("#amnt").val()).toFixed(2));
                });
            });
        })(jQuery);
    </script>

选择员工姓名，他/她的ID将显示在PHP的文本框中
