PHP Echo函数中的Javascript确认框

Question

我在PHP Echo函数中有一个名为“Delete”的链接。当用户单击它时，将调用delete.php页面并从数据库中删除所选书籍。所以，我想插入一个确认框，询问用户是否确定要删除该书，但我不知道该怎么做。

这是代码：

echo "<td><a class = 'echo_link' href='delete-book.php?ID={$Book->ID}'> Delete </a></td> \n";

Answer 1

使用此代码：

echo "<td>
<a class = 'echo_link' href='#' onclick='if(confirm(\"message\")) location.href=\"delete-book.php?ID={$Book->ID}\";'> Delete </a>
</td> \n";

Answer 2

它完美无缺......

 <a  href='http://www.google.com' onclick="return confirm('Are U sure?');"> Delete </a>

Answer 3

请试试这个：

echo "<td><a class = 'echo_link' href='delete-book.php?ID=5' onclick='return confirm(\"Are you sure to delete?\")'> Delete </a></td> \n";

Answer 4

你可以试试这段代码

<?php $bookid =  $Book->ID; ?>
<td>

</td> 
<?php echo"\n";
?>
