ShowMsg函數妙用

POST TIME:2020-09-24

在對DedeCMS做2次開發的時候可能提示信息會經常用到，為了方便在此將ShowMsg方法提取出來，使用方法：

ShowMsg（“提示信息”，“進行跳轉的頁面URL”）;

ShowMsg的代碼如下：

function ShowMsg($msg, $gourl, $onlymsg = 0, $limittime = 0) //系統提示信息
{
/*
*$msg 信息提示的內容
*$gourl 需要跳轉的網址
*$onlymsg 1 表示不自動跳轉 0表示自動跳轉
*$limittime 跳轉的時間
*/
    global $dsql, $cfg_ver_lang;
    if (eregi ( "^gb", $cfg_ver_lang ))
    $cfg_ver_lang = 'utf-8';
    $htmlhead = "<html>\r\n<head>\r\n<title>系統提示</title>\r\n<meta http-equiv=\"Content-Type\"
                 content=\"text/html; charset=utf-8\" />\r\n";
    $htmlhead .= "<base target='_self'/>\r\n</head>\r\n<body leftmargin='0' topmargin='0'>\r\n<center>\r\n<script>\r\n";
    $htmlfoot = "</script>\r\n</center>\r\n</body>\r\n</html>\r\n";

    if ($limittime == 0)
        $litime = 3000;
    else
        $litime = $limittime;

    if ($gourl == "-1") {
        if ($limittime == 0)
            $litime = 3000;
        $gourl = "javascript:history.go(-1);";
    }

    if ($gourl == "" || $onlymsg == 1) {
        $msg = "<script>alert(\"" . str_replace ( "\"", "“", $msg ) . "\");</script>";
    } else {
        $func = "     var pgo=0;
      function JumpUrl(){
        if(pgo==0){ location='$gourl'; pgo=1; }
      }\r\n";
        $rmsg = $func;
        $rmsg .= "document.write(\"<br /><div style='width:450px;padding:0px;border:1px solid #DADADA;'>";
        $rmsg .= "<div style='padding:6px;font-size:12px;border-bottom:1px solid #DADADA;
                 background:#DBEEBD url(wbg.gif)';'><b>提示信息！</b></div>\");\r\n";
        $rmsg .= "document.write(\"<div style='height:130px;font-size:10pt;background:#ffffff'><br />\");\r\n";
        $rmsg .= "document.write(\"".str_replace("\"","“",$msg)."\");\r\n";
        $rmsg .= "document.write(\"";
        if ($onlymsg == 0) {
            if ($gourl != "javascript:;" && $gourl != "") {
                $rmsg .= "<br/><br/><a href='" . $gourl . "'>如果你的瀏覽器沒反應，請點擊這里...</a>";
            }
            $rmsg .= "<br/><br/></div>\");\r\n";
            if ($gourl != "javascript:;" && $gourl != "") {
                $rmsg .= "setTimeout('JumpUrl()',$litime);";
            }
        } else {
            $rmsg .= "<br/><br/></div>\");\r\n";
        }
        $msg = $htmlhead . $rmsg . $htmlfoot;
    }
    if (isset ( $dsql ) && is_object ( $dsql ))
        @$dsql->Close ();
    echo $msg;
}
