我的網頁有一個下拉框和三個輸入框。每當我在我的下拉框中進行選擇時，它會自動將信息填充到文本框中。每個文本框旁邊還有一個「保存」按鈕。這使我可以更新該字段，如果它需要更改一次我點擊保存按鈕。因此，例如，如果我將下拉框的值硬編碼到我的更新語句中，它就可以工作，但我無法在不對其進行硬編碼的情況下使其工作。所以我認爲我只需要讓Javascript讀取我的下拉框中選擇的值。我怎樣才能解決這個問題？根據輸入值更新數據庫
下拉框代碼：
<div>
<div id="vendor">
<strong>Vendor:</strong>
</div>
<div class="align">
<select name="vendor_dropdown" id="ven" onChange="updateinput();">
<option value="">Choose a Vendor</option>
<?php foreach($users->fetchAll() as $user): ?>
<option
data-name="<?php echo $user['MR_POC_N'];?>"
data-email="<?php echo $user['MR_POC_E'];?>"
data-phone="<?php echo $user['MR_POC_P'];?>"
>
<?php echo $user['MR_Name'];?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
聯繫信息代碼，該代碼自動填充：
<div>
<div id="contact_info">
<strong>Contact Information:</strong><br>
</div>
<div class="align1">
<table align="left" id="contact">
<tr>
<td align="left">Name:</td>
<td><input type="text" id="name" class="name" name="name" style="margin-left: 5px"></td>
<td><input type="button" class="edit" name="edit" value="Save"></td>
</tr>
<tr>
<td align="left">Email:</td>
<td><input type="email" id="email" class="email" name="email" style="margin-left: 5px"></td>
<td><input type="button" class="edit" name="edit" value="Save"></td>
</tr>
<tr>
<td align="left">Phone Number:</td>
<td><input type="tel" id="tel" class="tel" name="number" style="margin-left: 5px"></td>
<td><input type="button" class="edit" name="edit" value="Save"></td>
</tr>
</table>
</div>
</div>
