另一个函数调用的函数不使用CSS

标签： javascript css function

下面代码中的问题是从另一个函数调用一个函数然后所有格式都丢失了 - 函数domenu调用doarticle与相关的页码OK但是doarticle函数根本不用CSS格式化。如果我独立调用函数，那么一切正常，只有当我从另一个调用问题时才会出现问题。

使用FIREBUG监控CSS：调用doarticle函数时，所有CSS数据都会从DOM中消失。

上面的Metas和CSS

以下文章HTML渲染引擎...... 

<script type="text/javascript">
function doarticle (counter)
{
// document.body.innerHTML = "";
hhgaudio = 0;
strpos = 0;
hhgstring = "";

    if (hhgdata[counter][2].substring(strpos,(strpos+7)) === "<HHGML>")
    {
        strpos = 7;
        if (hhgdata[counter][2].substring(strpos,(strpos+8)) == "<BANNER>") // large banner at the top of the article
        {
            strpos = strpos +8;

            while (hhgdata[counter][2].substring(strpos,(strpos+9)) != "</BANNER>")
            {
                hhgstring = hhgstring + hhgdata[counter][2].substring(strpos,(strpos+1));
                strpos++;
            }
            strpos = strpos + 9;
            hhgstring = "<img id=\"banner\" src=\"" + imgpath + hhgstring + "\" style=\"vertical-align: top\"/>";
        }   
        hhgstring = "<img class=\"banner\" src=\"" + imgpath + "hhg_entry.jpg\" style=\"vertical-align: bottom\"/><br/>" + hhgstring;
        document.write(hhgstring);
        hhgstring = "<table frame=\"void\" border=\"0\" cellpadding=\"2\"><tr><td>";        
        hhgstring = hhgstring + "<div class=\"topic\">"+ (hhgdata[counter][0].toUpperCase()) + "<br/></div>"; // main article topic
        hhgstring = hhgstring + "<div class=\"title\">" + hhgdata[counter][1] + "</div>"; // main article title
        hhgstring = hhgstring + "<div class=\"summary\">" + (hhgdata[counter][3].toUpperCase()) + "</div>"; // article sub heading
        hhgstring = hhgstring + "</td></tr></table>"
        document.write(hhgstring);
        hhgstring = "";
        footernum = 0;


    }   
    document.write("<br/><table border=\"0\" cellpadding=\"10\"><tr><td><span>Entry Ends.</span></tr></table><br/>");
} // end of <HHGML> 

</script>

菜单列表功能...... 

<script type="text/javascript">
function domenu (lastrecord)
{
    hhgstring = "<br/><br/><table border=\"0\" cellpadding=\"0\">";
    for (counter=1; counter<lastrecord; counter++)
    {
        recnum = lastrecord - counter;
        // hhgstring = hhgstring + "<tr><td><img id=\"imgpadded\" src=\"" + imgpath + hhgdata[recnum][4] + "\" align=\"left\"></td>";
        hhgstring = hhgstring + "<tr><td>" + hhgdata[recnum][4] + "</td>";
        hhgstring = hhgstring + "<td><span class=\"menutitle\" onclick=\"doarticle('" +recnum+ "');\">" + tab + hhgdata[recnum][1] + "<br/></span>";
        hhgstring = hhgstring + "<span class=\"menusummary\">" + tab + hhgdata[recnum][3] + "</span></td></tr>";
    }
    hhgstring = hhgstring + "</table>";
    document.write(hhgstring);
    // return(hhgselect); // older idea now depreciated.
}
</script>

</head>

<body>

数据库位... 

<?php
    $con = mysql_connect("XXXX","XXXX","XXXX");
    mysql_select_db("HHG", $con);
    if (!$con)
    {
        die('Could not connect: ' . mysql_error());
    }
    else 
    {
        $result = mysql_query("SELECT * FROM articles", $con);
        $numrows = mysql_num_rows($result);
    }
?> 

<script type="text/javascript">
    numrows = <?php echo $numrows; ?>;
    hhgdata = new Array(numrows);
    hhgfooter = new Array(10);
</script>

<?php
    $counter = 0;
    while ($row = mysql_fetch_assoc($result))
    {
        $hhgtitle = $row["hhgtitle"];
        $hhgtopic = $row["hhgtopic"];
        $hhgarticle = mysql_real_escape_string($row["hhgarticle"]);
        $hhgsummary = mysql_real_escape_string($row["hhgsummary"]);
        $hhgidimg = $row["hhgidimg"];
    ?>

将PHP转换为Javascript vars ... 

    <script type="text/javascript">
        counter = <?php echo $counter; ?>; 
        hhgtitle = <?php echo '"'.$hhgtitle.'"'; ?>;
        hhgtopic = <?php echo '"'.$hhgtopic.'"'; ?>;
        hhgarticle = <?php echo '"'.$hhgarticle.'"'; ?>;
        hhgsummary = <?php echo '"'.$hhgsummary.'"'; ?>;
        hhgidimg = <?php echo '"'.$hhgidimg.'"'; ?>; 
        hhgdata[counter] = new Array(5);
        hhgdata[counter][0]= hhgtopic;
        hhgdata[counter][1]= hhgtitle;
        hhgdata[counter][2]= hhgarticle
        hhgdata[counter][3]= hhgsummary;
        hhgdata[counter][4]= hhgidimg;
    </script>

    <?php
    $counter++;
    }
mysql_close($con);
?>

调用菜单脚本...... 

<script type="text/javascript">
imgpath = "images/";
tab = "&nbsp;&nbsp;&nbsp;&nbsp;";
hhgselect = domenu (numrows);
doarticle (hhgselect);
// document.body.innerHTML = ""; // clears the screen


</script>

</body>

</html>

答案 0 :(得分：2)

在“domenu”函数中，您将返回变量hhgselect。但是这个变量没有用在那个函数中也没有通过php初始化。请验证。

答案 1 :(得分：0)

document.write函数应替换为：

document.getElementById(divname).InnerHTML = "contents"方法。

这就是我所做的，它现在运作良好。
