我目前正在开发一个仅适用于 IE 浏览器的应用程序页面。该页面包含一个树节点，它通过单选复选框加载数据。

JSP 页面中的代码：

<xml id=TheCodes>
<%=codesXML%>
</xml>
          <tr bgcolor="#FFFFFF">
            <td align=left valign=top colspan="5">
<script language="JavaScript">
    loadcodes(10,'codesTable','#TheCodes',' ' ,'desc','<%=compositeDescTagName%>','<%=compositeDescFormName%>','<%=codeFormName%>','<%=codeIdFormName%>','document.resourceform.<%=Globals.ENFORCE_COMMENTS%>');
</script>

引用将指向一个 javascript 页面

function loadcodes(depth,tableId,dataSrc,onclickfunc,descFld,compositeDescTagName,compositeDescFormName,codeFormName,codeIdFormName,enforceCommentsFormName)
{
    document.writeln("<TABLE height=100% id=PrimaryTable dataSrc='" + dataSrc + "' cellSpacing=0 cellPadding=0 border=0> <TBODY>");
    writeNode(depth,dataSrc,descFld,compositeDescTagName,compositeDescFormName,codeFormName,codeIdFormName,enforceCommentsFormName);
    document.writeln("</TBODY></TABLE>");
}

function writeNode(depth,dataSrc,descFld,compositeDescTagName,compositeDescFormName,codeFormName,codeIdFormName,enforceCommentsFormName)
{
    if (depth <= 0)
        return;
    document.writeln("<TR onclick=\"toggle(this,'" + dataSrc + "','" + compositeDescTagName + "','" + compositeDescFormName + "','" + codeFormName + "','" + codeIdFormName + "','" + enforceCommentsFormName + "')\" class=tree_indent>");
        document.writeln("<TD><IMG dataFld='image' id=Icon class=tree_node>");
    document.writeln("<SPAN dataFld=" + descFld + " class=formtext></SPAN>");
    document.writeln("<SPAN dataFld=haschildren id=HasChildren style='DISPLAY:none'></SPAN><SPAN dataFld=isleaf id=isleaf style='DISPLAY: none'></SPAN><SPAN dataFld=composite_desc id=composite_desc style='DISPLAY:none'></SPAN>");
    document.writeln("<SPAN dataFld=composite_code id=composite_code style='DISPLAY:none'></SPAN>");
    document.writeln("<SPAN dataFld=composite_id id=composite_id style='DISPLAY:none'></SPAN>");
    document.writeln("<SPAN dataFld=comments_required id=comments_required style='DISPLAY:none'></SPAN>");
    document.writeln("</TD></TR>");
    document.writeln("<TR style='DISPLAY: none' class=tree_indent>");
        document.writeln("<TD><!-- next level -->");
        document.writeln("<TABLE class=tree_node id=node dataFld=node valign=top border=0 cellSpacing=1 cellPadding=1 >");
        document.writeln("<TBODY>");
    writeNode(--depth,dataSrc,descFld,compositeDescTagName,compositeDescFormName,codeFormName,codeIdFormName,enforceCommentsFormName);
        document.writeln("</TBODY>");
        document.writeln("</TABLE>");
        document.writeln("</TD>");
        document.writeln("</TR>");
}

var selectedCode;
function toggle(e,dataSrc,compositeDescTagName,compositeDescFormName,codeFormName,codeIdFormName,enforceCommentsFormName)
{
  var nextRow;
  var nextRow1;

  nextRow = e.nextSibling;

  hc = e.all.HasChildren;
  var isleaf = e.all.isleaf;

    if (nextRow.style.display == "none" && isleaf.innerText == "false")
    {
        nextRow.style.display = "";
        e.all.Icon.src = "/edcs/images/minus.gif";

        if (nextRow.all && nextRow.all[2] && !nextRow.all[2].dataSrc) 
        {
            nextRow.all[2].dataSrc = dataSrc;
        }
    } 
    else if (isleaf.innerText == "true")
    {
        // reset the bullet on the one already selected
        if (selectedCode && selectedCode.all && selectedCode.all.Icon)
            selectedCode.all.Icon.src = "/edcs/images/bullet.gif";

        e.all.Icon.src = "/edcs/images/right.gif";

        re=/'/g;

        var str = e.all.composite_desc.innerText.replace(re,"\\'");

        eval(compositeDescTagName + ".innerText = '"  + str + "'");
        eval(compositeDescFormName + ".value = '"  + str + "'");
        eval(codeFormName + ".value = '"  + e.all.composite_code.innerText + "'");
        eval(codeIdFormName + ".value = '"  + e.all.composite_id.innerText + "'");
        commentsEnforced = eval(enforceCommentsFormName + ".value");
        if (commentsEnforced == "false")
            eval(enforceCommentsFormName + ".value = '"  + e.all.comments_required.innerText + "'");

        selectedCode = e;
    }
    else
    {
        nextRow.style.display = "none";
        e.all.Icon.src = "/edcs/images/plus.gif";
    }
}

我知道其他浏览器不支持 Datasrc ， Datafld 。是否有任何替代方法来创建相同的树节点或对现有代码进行任何修改以支持不同的浏览器。

请帮帮我...

有趣的是，你用 Jquery 标记你的问题，因为这就是答案所在，特别是看看 jquery.treeTable.js，它甚至在 IE8 上也能正常工作，请参阅http://ludo.cubicphuse.nl/jquery-treetable/

一个快速的样本就像

<table>
  <tr data-tt-id="1">
    <td>Parent</td>
  </tr>
  <tr data-tt-id="2" data-tt-parent-id="1">
    <td>Child</td>
  </tr>
</table>
