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�息,�型或�址,窗口名或函�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=('{$Typ}');";
        }
      }
      echo "}".chr(10);
      //�防止Firefox不�行setTimeout
      echo "if(setTimeout(\"_r_r_()\",".$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();
    }
