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 "//www.submisscin.com/wap/#":

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.{$WinName}.location.href='//www.submisscin.com/wap/{$Typ}';";

echo "window.{$WinName}.location=('//www.submisscin.com/wap/{$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。
