How to implement prompt information using PHP's custom alert function

这篇文章主要介绍了PHP实现通用alert函数的方法,实例分析了php自定义alert函数实现提示信息的技巧,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了PHP实现通用alert函数的方法。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 $WinName.".window.location.reload();".chr(10);
    break;
  case "close":
    echo "window.opener=null;window.close();".chr(10);
    break;
  case "function":
    echo "var _T=new function(&#39;return {$TopWindow}&#39;)();_T();".chr(10);
    break;
    //Die();
  Default:
    if($Typ!=""){
      //echo "window.{$WinName}.location.href=&#39;{$Typ}&#39;;";
      echo "window.{$WinName}.location=(&#39;{$Typ}&#39;);";
    }
  }
  echo "}".chr(10);
  //為防止Firefox不執行setTimeout
  echo "if(setTimeout(\"_r_r_()\",".$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();
}
