本文实例讲述了PHP实现通用alert函数的方法。分享给大家供大家参考。具体如下：

函数:通用提示
参数:提示訊息,類型或網址,窗口名或函數名,延时毫秒
Alert("","function","close2",300);

代码如下：

function Alert($Str,$Typ="back",$TopWindow="",$Tim=100){ echo "<script>".chr(10); if(!empty($Str)){ echo "alert(\"Warning:\\n\\n{$Str}\\n\\n\");".chr(10); } echo "function _r_r_(){"; $WinName=(!empty($TopWindow))?"top":"self"; switch (StrToLower($Typ)){ case "#": break; case "back": echo $WinName.".history.go(-1);".chr(10); break; case "reload": echo $WinName.".window.location.reload();".chr(10); break; case "close": echo "window.opener=null;window.close();".chr(10); break; case "function": echo "var _T=new function('return {$TopWindow}')();_T();".chr(10); break; //Die(); Default: if($Typ!=""){ //echo "window.{$WinName}.location.href='{$Typ}';"; echo "window.{$WinName}.location=('{$Typ}');"; } } echo "}".chr(10); //為防止Firefox不執行setTimeout echo "if(setTimeout(\"_r_r_()\",".$Tim.")==2){_r_r_();}"; if($Tim==100){ echo "_r_r_();".chr(10); }else{ echo "setTimeout(\"_r_r_()\",".$Tim.");".chr(10); } echo "</script>".chr(10); Exit();}

希望本文所述对大家的php程序设计有所帮助。
