編輯將醫療手術事件添加到Google日曆的表單。在表單上是一個（外科醫生列表）選擇框，它從index.php文件中提取選項值。我試圖改變這種情況，讓用戶通過在文本框中輸入名稱然後單擊「添加」按鈕來將「外科醫生」添加到該選擇框列表中。需要用戶能夠將「添加選項」添加到選擇列表中
我的解決方案是在「外科醫生列表」選擇框下添加一個文本字段和一個按鈕。在名稱中鍵入，然後單擊提交按鈕會將新的外科醫生姓名寫入XML文件。然後，我將「外科醫生列表」選擇框從XML文件中拉出它的選項值。
我能夠創建輸入框和按鈕，將新的外科醫生名稱添加到XML文件，但現在我有兩個提交按鈕。當我嘗試將新的外科醫生姓名添加到XML文件時，它認爲我已經完成了整個表單，並且正在嘗試提交它。如何在不提交表單的情況下將新選項值發送到XML文件？任何信息表示讚賞。
這是當前選擇框（不是從XML文件還拉）和我下面的XML添加現場...
<input type="hidden" name="action" value="<?php if($edit) echo 'edit';else echo 'insert';?>">
<input type="hidden" name="event_id" value="<?php if($edit) echo $event_data['id'];else echo '0';?>">
<div class="col-md-6 col-sm-6 col-xs-12">

目前提交我的除了與衝突在窗體上按鈕在這裏...

最簡單的方法是如果用戶添加了一個新的外科醫生姓名，請將其作爲提交操作的一部分（從此將其添加到框中），而不是試圖在即時執行該操作。 –
你會碰到一個我能看到的例子嗎？任何信息apprecaited！ –
