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();

}
