layui.laytpl的if else 写法

表格操作列

<!-- 表格操作列 -->
<script type="text/html" id="role-table-bar">
    <a class="layui-btn layui-btn-primary layui-btn-xs" lay-event="edit">修改</a>
    <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
    <a class="layui-btn layui-btn-xs" lay-event="menu">菜单管理</a>

    {{# if (d.systemName === 'saas-upms') { }}
    <a class="layui-btn layui-btn-xs" lay-event="auth">权限管理</a>
    {{# } else { }}
    <a class="layui-btn layui-btn-xs layui-btn-disabled" lay-event="auth">权限管理</a>
    {{# } }}

</script>

渲染表格

layui.use(['form', 'table', 'util', 'config', 'admin', 'formSelects'], function () {
        var form = layui.form;
        var table = layui.table;
        var config = layui.config;
        var layer = layui.layer;
        var util = layui.util;
        var admin = layui.admin;
        var formSelects = layui.formSelects;

        //渲染表格
        table.render({
            elem: '#role-table',
            url: 127.0.0.1 + '/roles',
            where: {
                access_token: config.getToken().access_token
            },
            page: true,
            cols: [[
                {type: 'numbers'},
                {field: 'id', sort: true, title: 'ID',width: 80},
                {field: 'name', sort: true, title: '角色名'},
                {field: 'systemName', sort: true, title: '所属系统'},
                {field: 'code', sort: true, title: 'Code'},
                {
                    field: 'createTime', sort: true, templet: function (d) {
                        return util.toDateString(d.createTime);
                    }, title: '创建时间'
                },
                {field: 'center',toolbar:'#role-table-bar', title: '操作',width: 250}
            ]]
        });
  });

效果图

这种直接在表格field判断也可以

treetable.render({
                    treeColIndex: 1,
                    treeSpid: -1,
                    treeIdName: 'id',
                    treePidName: 'parentId',
                    elem: '#menus-table',
                    url: config.base_server + 'api-user/menus/findAlls',
                    where: {
                        access_token: config.getToken().access_token
                    },
                    page: false,
                    cols: [[
                        {type: 'numbers'},
                        {field: 'name', minWidth: 200, title: '菜单名称'},
                        {field: 'systemName', title: '所属系统'},
                        {field: 'url', title: '菜单路由'},
                        {field: 'path', title: '菜单URL'},
                        {field: 'css',  align: 'center', title: '样式'},
                        {field: 'sort', width: 80, align: 'center', title: '排序号'},
                        {
                            field: 'isMenu', width: 80, align: 'center', templet: function (d) {
                                if (d.isMenu == 2) {
                                    return '<span class="layui-badge layui-bg-gray">按钮</span>';
                                }
                                if (d.parentId == -1) {
                                    return '<span class="layui-badge layui-bg-blue">目录</span>';
                                } else {
                                    return '<span class="layui-badge-rim">菜单</span>';
                                }
                            }, title: '类型'
                        },
                        {templet: '#menus-state', width: 120, align: 'center', title: '操作'}
                    ]]
                });
