試圖根據點擊事件從數據庫獲取信息並將數據加載到稍後將在表單中使用的變量中。這是代碼的一部分。已經使用PDO連接到銷售代表表格:pdo調用填充變量以便稍後使用

{
var country_id = evt.target.id
document.getElementById('country_name').firstChild.data = country_id
<?php
$country = $_GET['country_name'];

這與我關於svg的其他問題有關。 (displaying data from sql from clicking on svg map)一旦我點擊某個svg,它就會填充用於顯示有關所點擊國家/地區的數據的變量。這些變量也用於填充聯繫表單。
它不想填充表格?

嘿。你應該在這裏複製/粘貼確切的錯誤(即使它對你來說似乎是一個簡單的語法錯誤。)另外,你提到你的其他問題?還有什麼問題?你能添加一個鏈接嗎?如您所說, –
