首先，先寫自定義的方法：

function (sex) {
    var Max = 2;
    var Min = 1;
    var Range = Max - Min;
    var Rand = Math.random();
    var res = (Min + Math.round(Rand * Range));
    if (sex == ‘女‘) {
        res = res + 2;
    }
    return res;
}

然後，在juicer裏註冊這個方法。

juicer.register(‘rand‘, app.rand);

最後，在模板裏使用這個方法：

{@each list as it,k}
    {@if k < 10}
        <li class="{@if k > 3} hide {@/if}">
            <div class="city-head">
                <img src="images/touxiang${it.sex|rand}.png" alt="" />
            </div>
            <div class="city-process"
 
>
                <div class="city-name">
                    ${it.name}
                    &nbsp;&nbsp;
                    ${it.tel}
                </div>
                <div class="progress progress-striped">
                    <div class="progress-bar progress-bar-info"
 
 role="progressbar progress-bar-success" aria-valuenow="${it.scale}" aria-valuemin="0" aria-valuemax="100" style="width: ${it.scale}%"></div>
                </div>
            </div>
            <div class="city-km">
                ${it.distance}km
            </div>
            <div class="clearfix"></div>
        </li>
    {@/if}
{@/each}
<li>
    <div id="citymore" class="more hidecity" onclick="app.showMoreCitys();">更多詳細信息<i class="icon icon-chevron-down"></i></div>
</li>
