freemarker循環數字及取下標

循環數字與循環集合的區別是循環集合是<#list arrayList as list >，循環數字是<#list 1..(max要循環的數字) as n別名 >
取當前循環的下標沒什麼區別，list_index，n_index;下面是我使用的代碼


<#list 1..(6-patientMedicals?size) as n >
    <#if (patientMedicals?size+n_index+1)==4>
        <label for="inputname" class="col-sm-2 control-label text-center-u"></label>
    </#if>
    <div class="col-sm-3 col-sm-3-a">
        <input type="hidden" id="imgId${patientMedicals?size+1+n_index}" value="0"/>
        <input type="hidden" id="coverUrl${patientMedicals?size+n_index+1}" name="cover${patientMedicals?size+n_index+1}" value=""/>
        <div id="box">
            <div id="coverImg${patientMedicals?size+n_index+1}" class="left-alt align-1 left-8"></div>
        </div>
        <img src="" id="coverOld${patientMedicals?size+n_index+1}" style="max-width: 300px;" class="png-size">
    </div>
</#list>
