JavaScript確認無法運作

Question

echo "<td><a onclick=\"confirm('Are you sure you want to permanently delete this post?');\" href='posts.php?id=".$res['id']."'>view</a></td>";

用PHP生成，確認不會彈出。我在做什么錯？ 感謝您的查詢。

Answer 1

采用

onclick="return confirm('Are you sure you want to permanently delete this post?');"

Answer 2

嘗試：

echo "<td><a onclick='return confirm('Are you sure you want to permanently delete this post?');' href='posts.php?id=".$res['id']."'>view</a>";

Answer 3

改用：

echo "<td><a onclick="return confirm('Are you sure you want to permanently delete this post?');" href="posts.php?id=".$res['id']."'>view</a></td>";

confirm返回true還是false

Answer 4

添加return false或true以避免進一步執行

    if(Confirm())
           return true;
        else
          return false;
