Freemark備忘錄

一、顯示日期

1、選擇顯示格式

${(model.date?string("HH:mm"))!}

2、常規顯示

${(model.date?date)!}

${(model.date?datetime)!}

二、空字符串，空Map

<#if form.id?has_content>
      <a type="button" class="btn btn-warning catrgory-remove">刪除</a>
</#if>

<#assign pictureId=product.pictureIds?has_content?string(product.pictureIds[0],"")/>

三、便利Map

<#list map?keys as key>

${key}=${map[key]}<br />

</#list>

四、全局驗證

<#escape x as (x)!>

</#escape>

五、Select默認選中

1、${(a.id=(t.orientation.id!))?string('selected="selected"','')}

2、<#assign selected = (orientationId?? && ms.id==orientationId)?string("selected='selected'","") />
<option value="${ms.id}" ${selected}>${ms.name}</option>

3、<#list (industries)! as i>

<#assign check=""/>
<#list (incubationTeamSearcher.industries)! as ind>
<#if ind==i>
<#assign check="checked">
</#if>
</#list>
<input type="checkbox"  ${check} value="${i!}" name="industries" />${i}
    </#list>
