在我的项目跟踪器程序中,我有一个表,其中的行对应于项目,列对应于项目的不同信息(名称、截止日期、状态等)。最后一列应该是“更多”列,当您按下它时,它应该显示项目附加属性的下拉列表。我如何在 Grails 中做到这一点?下面是我的list.gsp:

<calendar:resources lang="en"/>

<!doctype html>
<html>
    <head>
        <meta name="layout" content="layoutMain"/>
        <g:set var="entityName" value="${message(code: 'project.label', default: 'Project')}" />
        <title><g:message code="default.list.label" args="[entityName]" /></title>
    </head>
    <body>
        <div class="nav" role="navigation">
            <ul>
                <li><g:link class="create" action="create"><button>New Project</button></g:link></li>
            </ul>
        </div>
        <div id="list-project" class="content scaffold-list" role="main">
            <h1><g:message code="default.list.label" args="[entityName]" /></h1>
            <g:if test="${flash.message}">
            <div class="message" role="status">${flash.message}</div>
            </g:if>
            <table>
                <thead>
                    <tr>

                        <g:sortableColumn property="name" title="${message(code: 'project.name.label', default: 'Name')}" />

如果你想使用标准的 Grails,你可以使用g:select标签在 Grails 中创建一个下拉菜单。一个更漂亮的解决方案可能是使用 jQuery(或类似的)来显示隐藏 HTML 块。

如果您的项目域看起来像:

class Project {

    String name
...
    // more info
    String  attr1
    int     attr2
    boolean isAttr3

}

您可以向您的域添加一种便捷方法,以将字段聚合到一个列表(或可能是另一个对象)中,该列表可用于下拉框。例如

// utility getter to aggregate the fields into an array 
def getMoreInfo() {
    [attr1, attr2, isAttr3]
}

然后,您可以在 GSP 中使用以下内容:

<td><g:select name="more" from="${projectInstance.moreInfo}" /></td>

单击更多列时,您可以向某个操作发送 Ajax 请求,该操作可以为您带来两个数组的 JSON:

{extraColumns:{c1,c2}, columnValues:{{v11,v12}, {v21,v22}}}

在 Ajax 的响应中,您可以解析 JSON 并为标题创建附加列并为行创建附加列值。
