请教一下jsp中使用inner HTML的问题

Question

 代码如下，执行是页面变成空白页面，前台也没报错，不知道什么原因了。

    <div class="box2">
        <div class="btn"><h2>产品类别</h2><span class="span2"></span></div>
        <div id="repostdiv" class="tab" onload="inhtml()">   


<script type="text/javascript">

<%-- function inhtml(){
    var html = [];
    html.push('<div class="leibie lb1">');
    html.push('<h3 class="lbt"><%=lr.optString("CC_NAME") %></h3>');
    html.push('<div class="lbc"><a href="#">儿童干脆面</a><a href="#">青食挂面</a><a href="#">青稞面食</a><a href="#">小苏打面</a>');
    html.push('</div><div class="clear"></div></div>');
    document.getElementById('repostdiv').innerHTML = html.join(''); 
} --%>

    function inhtml(){
        var html = [];
        for (var i = 0; i < lrs1.size() ; i++) {
            lrCP = lrs1.get(i);

            html.push('<div class="leibie lb1">');
            html.push('<h3 class="lbt"><%=lrCP.optString("CPC_NAME")%></h3>');
            html.push('<div class="lbc">');
            <%  
            LMRecord lrCPS = null;
            try{
                PublicBean.dbConnect();
                LMResultSet lrs2 = PublicBean.getrs2LMRs("SELECT DISTINCT cpc.cpc_name FROM cy_pro_class cpc LEFT JOIN cy_product cp ON cpc.cpc_order = cp.cp_class WHERE 1 = 1 AND cpc.cpc_level = '2'  AND cp_company = '"+seq+"' AND SUBSTRING_INDEX(substring_index(cpc_namepath, '/', 2),'/',-1) = '"+lrCP.optString("CPC_NAME")+"' ");
            }catch(Exception e){
                e.printStackTrace();
                lrCP = new LMRecord();
            }finally{
                PublicBean.closeResultSet();
            }
            %>
            for (var j = 0; j < lrs2.size() ; j++) {
                lrCPS = lrs1.get(j);
                html.push('<a href="#"><%=lrCPS.optString("CPC_NAME")%></a>');
            }
            html.push('</div><div class="clear"></div></div>');
        }
            document.getElementById('repostdiv').innerHTML = html.join(''); 
    } 

</script>

        </div>
    </div>

lrs2是服务器端的变量，你放js里面怎么可能引用到，前端肯定报错了。。

       function inhtml(){
            var html = [];
            for (var i = 0; i < lrs1.size() ; i++) {
                lrCP = lrs1.get(i);

                html.push('<div class="leibie lb1">');
                html.push('<h3 class="lbt"><%=lrCP.optString("CPC_NAME")%></h3>');
                html.push('<div class="lbc">');
                <%
                LMRecord lrCPS = null;
                try{
                    PublicBean.dbConnect();
                    LMResultSet lrs2 = PublicBean.getrs2LMRs("SELECT DISTINCT cpc.cpc_name FROM cy_pro_class cpc LEFT JOIN cy_product cp ON cpc.cpc_order = cp.cp_class WHERE 1 = 1 AND cpc.cpc_level = '2'  AND cp_company = '"+seq+"' AND SUBSTRING_INDEX(substring_index(cpc_namepath, '/', 2),'/',-1) = '"+lrCP.optString("CPC_NAME")+"' ");
                }catch(Exception e){
                    e.printStackTrace();
                    lrCP = new LMRecord();
                }finally{
                    PublicBean.closeResultSet();
            }

            for (var j = 0; j < lrs2.size() ; j++) {
                lrCPS = lrs1.get(j);////服务器端闭合标签放这里%>
                html.push('<a href="#"><%=lrCPS.optString("CPC_NAME")%></a>');
           <% }%>
            html.push('</div><div class="clear"></div></div>');
        }
    document.getElementById('repostdiv').innerHTML = html.join('');
    }
