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。
