我使用数据库中的数据创建了一个表,为了创建它,我使用了一个循环来从我需要的列中获取每条数据。现在,我打了一个javascript HTML 中的函数onClick的输入。但是,我不断收到错误消息。该功能似乎确实有效,它只是实际的 echo这似乎是错误的。在第 58 行,您可以看到我正在创建一个表并插入行。

更新

我的 javascript 函数正在运行。错误是在它尝试设置 <td> 时出现的宽度和对齐方式。我得到的错误是:

最佳答案

正如我在上面的评论中提到的,您需要为所有属性和 JS 调用使用引号。此外,请记住您的 onClick 的内容必须是有效的 JS。因此,您作为参数传递给函数的字符串应该用引号引起来。

echo '<tr class="services"><td name="'.$num.'"><input type="submit" onClick="buy(\''.$userRow['userService'.$id].'\',\''.$userRow['userServiceCost'.$id].'\',\''.$userRow['userServiceEmail'].'\')"></td><td width="250" align="center">'.$userRow['userService'.$id].'</td><td width="250" align="center">'.$userRow['userServiceCost'.$id].'</td><td width="250" align="center">'.$userRow['userServiceDes'.$id].'</td><td width="250" align="center">'.$userRow['userServiceName'.$id].'</td></tr>';
