ShowMsg函数妙用

在对DedeCMS做2次开发的时候可能提示信息会经常用到，为了方便在此将ShowMsg方法提取出来，使用方法：

ShowMsg（“提示信息”，“进行跳转的页面URL”）;

ShowMsg的代码如下：

function ShowMsg($msg, $gourl, $onlymsg = 0, $limittime = 0) //系统提示信息
{

    global $dsql, $cfg_ver_lang;
    if (eregi ( "^gb", $cfg_ver_lang ))
    $cfg_ver_lang = 'utf-8';
    $htmlhead = "rnrnrn                  content="text/html; charset=utf-8" />rn";
    $htmlhead .= "rnrnrn

rnrnrnrnrn";
 
    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 = "";
    } else {
        $func = "     var pgo=0;
      function JumpUrl(){
        if(pgo==0){ location='$gourl'; pgo=1; }
      }rn";
        $rmsg = $func;
        $rmsg .= "document.write("
";
        $rmsg .= "                  background:#DBEEBD url(wbg.gif)';'>提示信息！");rn";
        $rmsg .= "document.write("
");rn";
        $rmsg .= "document.write("".str_replace(""","“",$msg)."");rn";
        $rmsg .= "document.write("";
        if ($onlymsg == 0) {
            if ($gourl != "javascript:;" && $gourl != "") {
                $rmsg .= "

如果你的浏览器没反应，请点击这里...";
            }
            $rmsg .= "

");rn";
            if ($gourl != "javascript:;" && $gourl != "") {
                $rmsg .= "setTimeout('JumpUrl()',$litime);";
            }
        } else {
            $rmsg .= "

");rn";
        }
        $msg = $htmlhead . $rmsg . $htmlfoot;
    }
    if (isset ( $dsql ) && is_object ( $dsql ))
        @$dsql->Close ();
    echo $msg;
}
