转账问题时如何获取信息

同学你好，通过js获取信息，代码如下：

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
        <form class="form-inline" action="select.php" method="post" enctype="multipart/form-data">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title" id="myModalLabel">转账</h4>
                </div>
                <div class="modal-body">
                    <p>
                        收款人：
                        <select name="id" id='transfer-person' class="form-control">
                            <?php foreach ($data as $row):?>
                                <option value="<?php echo $row['id'];?>"><?php echo $row['name'] ?></option>
                            <?php endforeach ?>
                        </select>
                    </p>
                    <br />
                    <p>转账金额：<input type="text" class="form-control" id="exampleInputEmail1" name="trans_money" placeholder="请输入数字"></p>
                </div>
                <div class="modal-footer">
                    <button type="submit" class="btn btn-primary" name="submit" id="submit" onclick="show(this)">确认转账</button>
                    <button type="reset" class="btn btn-default">重置</button>
                </div>
            </div>
        </form>
    </div>
</div>
<script type="text/javascript">
    $("#exampleModal").modal("hide");
    $('#myModal').on('show.bs.modal', function (event) {
     // relatedTarget 事件属性返回与事件的目标节点相关的节点。
         var a = $(event.relatedTarget) 
         var userName = a.context.dataset.user;
         var modal = $(this);
         //获取select option value值
        // console.log(userName);
        $("#transfer-person").each(function(){
            $('#transfer-person').val(userName);
        });
    });
</script>

祝学习愉快！
