Grails中使用ajax异步获取数据

<g:formRemote
     name="myForm"
     url="[controller: 'user', action: 'ajaxGetUsers']"
         update="message"
>
     <g:select
         class="form-control"
         name="rolename"
         from="${roles}"
         optionKey="id"
             noSelection="['':'-按角色查询工号-']"
    />
        <input type="submit" class="btn btn-primary" value="查询" />
</g:formRemote >

def ajaxGetUsers = {
        def role = Role.get(params.rolename.toInteger())
        def users = role?.users
        println users
        render(template:"userlists",model:[msg:users])
}

<div id="message">
  <g:render template="userlists"/>
</div>

格式可以自己定义
<g:each in="${msg}" var="m">
    ${m}<br/>
</g:each>

<g:select class="form-control"
      name="username" 
      from="${users}"
      optionKey="id"
          noSelection="['':'-按姓名查询信息-']"
          onchange="${remoteFunction(controller:'user',action: 'userinfo',
          update: 'userinfo',
          params: '\'id=\' + this.value')}"
/>

def userinfo(){
        println params
        def user = User.get(params.id)
        render(template:"userinfo",model:[user:user])
    }

<div id="userinfo">
    <g:render template="userlists"/>
</div>

姓名:${user.name}<br/>
工号:${user.jobId}<br/>
