Javascript 为什么每次我在我的网站上打印一个部分时，它都会显示字符和符号，而不是实际的文本？
我试图在我的网站上有一个打印功能。我已经看到一些代码可以做到这一点，所以我把它集成到我的程序中。然而，在打印示例页面期间，打印的只是符号和字符，而不是实际的格式和文本。请。帮助这是我的密码。多谢各位Javascript 为什么每次我在我的网站上打印一个部分时，它都会显示字符和符号，而不是实际的文本？,javascript,php,html,Javascript,Php,Html,我试图在我的网站上有一个打印功能。我已经看到一些代码可以做到这一点，所以我把它集成到我的程序中。然而，在打印示例页面期间，打印的只是符号和字符，而不是实际的格式和文本。请。帮助这是我的密码。多谢各位 <!--database connection--> <?php session_start(); include('connection.php'); ?> <!--end database connection--> <html>

这是因为div没有得到css。因此，添加内联css或在打印div中保留相关css。谢谢。我试过了，但它仍然显示符号和字符。打印函数是否读取php代码？因为我认为问题在于，当页面加载后，它不能在Echoc中打印值，它被转换成纯html，所以我们可以使用html并打印。你试过内联css吗？因为它会起作用。我在我的一个项目中做到了这一点。所以，在测试html代码中尝试一下，然后再去做。
