js弹窗出错。高手帮改一下。急急急!!!!!!
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?php $qq=$_POST['qq'];if(!$qq==""){ if( strlen( $qq ) > 12 || strlen( $qq ) alert('对不起,你输入的QQ号码无效.请重新输入.');history.back();"; exit(); }?>
加粗部分出错。不会弹出提示。请高手帮看下，谢谢。/
if语句的前段好用。$qq ) > 12 || strlen( $qq ) 后段不好用。 !is_numeric( $qq ) || $qq
------解决方案--------------------
可以用正则 /^[1-9][\d]{4,11}$/ 匹配
is_numeric 对于 “00000001”，“1e10”等都是合法的
