gender(inList:["M","F"]);

}

<g:select name="gender" value="${userInstance?.gender}"

valueMessagePrefix="user.gender" />

<g:select optionKey="id" from="${NewsClass.list()}" name="newsClass.id" value="${newsInstance?.newsClass?.id}" noSelection="${['null':'===请选择===']}"></g:select>

② 单选框——

<g:radio name="gender" value="M" checked="${userInstance?.gender?.equals('M')}"></g:radio>

<g:radio name="gender" value="F" checked="${userInstance?.gender?.equals('F')}"></g:radio>

③ 文本编辑插件

<resource:richTextEditor type="full" />

<richui:richTextEditor name="aContent" value="${aritcleInstance?.aContent}" />

④ 时间控件插件

<resource:dateChooser />

<richui:dateChooser name="aDate" format="yyyy-MM-dd"

value="${aritcleInstance?.aDate}" style="width:200px" />

⑤ 标签

fieldValue标签：取出某一bean中的某一个field得值

${fieldValue(bean: aritcleInstance, field: "aSource")}

G:link标签：输出超级链接

指定controller和action属性构造链接

<g:link controller="user" action="show" id="${aritcleInstance.id}"></g:link>

<g:link action="show" params="[id:1,style: 'red']"></g:link>
