PHP popup dialog

This article mainly introduces the PHP pop-up dialog box. Interested friends can refer to it. I hope it will be helpful to everyone.

1. PHP pops up a dialog box

< ?PHP 
echo "< script language=
\"JavaScript\">alert
(\"你好\");< /script>"; 
?> 
//或者
< ?PHP 
print "< script language=
\"JavaScript\">alert
(\"你好\");< /script>"; 
?>

2. If you need PHP to pop up a dialog box and return to the original page, you can write like this

< ?PHP 
echo "< script language=
\"JavaScript\">\r\n"; 
echo " alert(\"你好\");\r\n"; 
echo " history.back();\r\n"; 
echo "< /script>"; 
exit; 
?> 
//或者
< ?PHP 
print "< script language=
\"JavaScript\">\r\n"; 
print " alert(\"你好\");\r\n"; 
print " history.back();\r\n"; 
print "< /script>"; 
exit; 
?>

3. If you need PHP to pop up a dialog box and replace the original page with a new page (replace the current history record), the original page can be written like this

< ?PHP 
echo "< script language=
\"JavaScript\">\r\n"; 
echo " alert(\"你好\");\r\n"; 
echo " location.replace
(\"http://www.jb51.net/\");
\r\n"; // 自己修改网址 
echo "< /script>"; 
exit; 
?> 
或者

< ?PHP 
print "< script language=
\"JavaScript\">\r\n"; 
print " alert(\"你好\");\r\n"; 
print " location.replace
(\"http://www.jb51.net/\");
\r\n"; // 自己修改网址 
print "< /script>"; 
exit; 
?>
