PHP實現(xiàn)通用alert函數(shù)的方法

這篇文章主要介紹了PHP實現(xiàn)通用alert函數(shù)的方法,實例分析了php自定義alert函數(shù)實現(xiàn)提示信息的技巧,非常具有實用價值,需要的朋友可以參考下
    本文實例講述了PHP實現(xiàn)通用alert函數(shù)的方法。分享給大家供大家參考。具體如下：
    函數(shù):通用提示
    參數(shù):提示訊息,類型或網(wǎng)址,窗口名或函數(shù)名,延時毫秒
    Alert("","function","close2",300);
    代碼如下:
    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=('{$Typ}');";
    }
    }
    echo "}".chr(10);
    //為防止Firefox不執(zhí)行setTimeout
    echo "if(setTimeout(\"_r_r_()\",".$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();
    }
    希望本文所述對大家的php程序設計有所幫助。
