怎么在java后台代码里拼接html代码

                <div class="FormInput">
                    <select name="typeId" id="select" onchange="ChangeResourceType(this);">
                    </select>
                    <!--<html:select id="typeId" name="typeId"  fistOption="{$jsp.common.select.firstoption#}"   list="<%=PropKey.RESOURCE_TYPE_LIST%>">
                        <html:option label="typeName" value="typeId" />
                    </html:select>
                --></div>
            </div>  
            <div class="FormItemRight" >  
                <div styleClass="edit-talbe-label"><html:label label="{$jsp.cra.resource.speccifytype.amount#}"/></div> 
                <div class="FormInput"><input type="text" name="amount" id="amount" value='1'/></div>
            </div>  
        </div>

就像上面这段代码怎么写在java代码里，然后怎么通过js切换

strData.append("

" + map.get("AvgScoreRank")+ "以上" + "");
js:
$(doc).html('').html(data);

        String ss = "";
        ss +=   "<div class=\"FormInput\">";
        ss +=   "<select name=\"typeId\" id=\"select\" onchange=\"ChangeResourceType(this);\">";
        ss +=   " </select>";
        ss +=   " <!--<html:select id=\"typeId\" name=\"typeId\"  fistOption=\"{$jsp.common.select.firstoption#}\"   list=\"<%=PropKey.RESOURCE_TYPE_LIST%>\">";
        ss +=   "<html:option label=\"typeName\" value=\"typeId\" />";
        ss +=   "  </html:select>";
        ss +=   "  --></div>";
        ss +=   "</div>  ";
        ss +=   " <div class=\"FormItemRight\" > "; 
        ss +=   "  <div styleClass=\"edit-talbe-label\"><html:label label=\"{$jsp.cra.resource.speccifytype.amount#}\"/></div> ";
        ss +=   " <div class=\"FormInput\"><input type=\"text\" name=\"amount\" id=\"amount\" value='1'/></div>";
        ss +=   " </div> "; 
        ss +=   " </div>";

一般在后台将数据格式转成JSON,在前台页面接收数据后拼接
给你一个我做的例子.

把网页以文件形式保存，然后调用这个文件
