PHP实现通用alert函数的方法

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。
