单击警报时打破内部

Question

我有一个带有警报的按钮字段，然后才会被执行。那＆＃34; onclick＆＃34;警报代码包含文本。我无法在文本中制动。我该如何解决这个问题？我发现了[这个问题] [1]，但我还是无法修复它。问题是当我点击按钮时根本没有任何事情发生。

＆＃13;

＆＃13;

echo "<tr><td><strong>
<form action='respondent.php' method='post'>
 <input type='hidden' name='rid' value='".$row['rid']."'>
 <input type='hidden' name='firstname' value='".$row['firstname']."'> 
<a href='respondent.php'><button>".$row['firstname']." ".$row['lastname']."</button></a>

 <input type='submit' name='submit' value='Select'>
 </form>
 </strong></td> 
 
 <td>".$row['email']."</td> 
 <td>".$row['pointsummary']."</td> 
 <td>".$row['datetime']."</td>
 
<td> 
<input type='button' action='deleterespondent.php' value='Delete' 
onclick="return confirm('Are you sure you \n want to delete?');">
</td>
</tr>";

＆＃13;

＆＃13;

＆＃13;

Answer 1

以这种方式使用<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> \n \ n在字符串中使用，因此无需使用confirm('Are you sure you \n want to delete?');

删除single quotes＆＃39;在\n附近

<input type='button' action='deleterespondent.php' value='Delete' 
onclick=\"return confirm('Are you sure you \\n want to delete?');\">
