在制作数据可视化大屏时，尤其是在触摸屏演示时，需要开发和设计对应的数据大屏引导页。基于常见场景，单独开发数据大屏引导页。
- 前端可自行配置大屏引导页背景图、标题信息；
- 前端可自行引导菜单（根据大屏的特殊要求，案例菜单最多6个，最少1个）；
- 基于php原生代码开发，未使用任何模版引擎；
- 适合于菜鸟入门使用；
1.引入外部js库
项目使用到layui.js的图标和弹窗功能，因此作为常备js库引入页面；其他都外部文件为项目自定义文件。
<script type="text/javascript" src="js/jquery.min.js"></script> <script type="text/javascript" src="js/functions.js"></script> <!--layui封装库--> <script src="js/layui/layui.js" charset="utf-8"></script> <link rel="stylesheet" href="js/layui/css/layui.css"> <!--核心样式表--> <link rel="stylesheet" href="css/common.css">
2.HTML排版
- 为实现大屏背景的自行配置，body的背景css直接写在了页面中，通过
style="background: #0a0d26 url('./images/mainbg1.jpg')进行代码的切换。
<body style="background: #0a0d26 url('./images/mainbg1.jpg') no-repeat top center; "> <div class="panel"> <div class="title"> <p>科为数据可视化服务中心</p> <p>Kewei Data Visualization Service Center</p> </div> <div class="guid_menu"> <a href="https://www.baidu.com/"><div class="subMenu sub_bg1"> <p><i class="layui-icon layui-icon-website"></i></p> <p>数据中心</p> <p>Kewei Service</p> </div></a> <a href="https://www.baidu.com/"><div class="subMenu sub_bg2"> <p><i class="layui-icon layui-icon-upload-drag"></i></p> <p>用户中心</p> <p>Kewei Service</p> </div></a> <a href="https://www.baidu.com/"><div class="subMenu sub_bg3"> <p><i class="layui-icon layui-icon-user"></i></p> <p>后台管理</p> <p>Kewei Service</p> </div></a> <a href="https://www.baidu.com/"><div class="subMenu sub_bg4"> <p><i class="layui-icon layui-icon-set"></i></p> <p>服务支持</p> <p>Kewei Service</p> </div></a> <a href="https://www.baidu.com/"><div class="subMenu sub_bg5"> <p><i class="layui-icon layui-icon-app"></i></p> <p>产品概况</p> <p>Kewei Service</p> </div></a> <a href="https://www.baidu.com/"><div class="subMenu sub_bg6"> <p><i class="layui-icon layui-icon-tabs"></i></p> <p>城市管理</p> <p>Kewei Service</p> </div></a> </div> </div>
3.项目配置文件
项目配置文件位置:conf/config.php。初始代码如下，可以通过表单进行全局更新。
<?php return [ 'sys_title' => '数据可视化服务中心', 'sys_title_en' => 'Data Visualization Service Center', 'sys_bg_img' => './images/mainbg3.jpg', 'links' => [ ['title' => '数据中心', 'links' => 'http://www.baidu.com/'], ['title' => '用户中心', 'links' => 'http://www.baidu.com/'], ['title' => '后台管理', 'links' => 'http://www.baidu.com/'], ['title' => '服务支持', 'links' => 'http://www.baidu.com/'], ['title' => '产品概况', 'links' => 'http://www.baidu.com/'], ['title' => '智慧城市', 'links' => 'http://www.baidu.com/'] ] ];
4.菜单图标自动匹配
通过循环配置文件conf/config.php中’links’数据，来判断不同菜单的坐标显示方式。
function getIcon($num) { switch ($num) { case 1: echo 'layui-icon-website'; break; case 2: echo 'layui-icon-upload-drag'; break; case 3: echo 'layui-icon-user'; break; case 4: echo 'layui-icon-set'; break; case 5: echo 'layui-icon-app'; break; case 6: echo 'layui-icon-tabs'; break; default: echo 'layui-icon-website'; } }
5.php与html混排
示例代码为生产环境下，php和 html共同作用展示项目内容。
<body style="background: #0a0d26 url('<?php echo $DATA['sys_bg_img'] ?>') no-repeat top center; "> <div class="panel"> <div class="title"> <p><?php echo $DATA['sys_title'] ?></p> <p><?php echo $DATA['sys_title_en'] ?></p> </div> <div class="guid_menu"> <?php for ($i = 0; $i < count($DATA['links']); $i++) { ?> <?php if ($DATA['links'][$i]['title'] !="" && $DATA['links'][$i]['links'] !="") {?> <a href="<?php echo $DATA['links'][$i]['links'] ?>"><div class="subMenu sub_bg<?php echo ($i + 1) ?>"> <p><i class="layui-icon <?php getIcon(($i + 1)) ?>"></i></p> <p><?php echo $DATA['links'][$i]['title'] ?></p> <p>Kewei Service</p> </div></a> <?php }} ?> </div> <div class="copyright"><p><span onclick="getZoomUrl('导航链接', 'links.php', '', '', '')"><i class="layui-icon layui-icon-component"></i> </span> 备案号：<a href="https://beian.miit.gov.cn/" target="_blank">粤ICP备2022021238号-2</a> </p></div> </div>
6.CSS样式表
主要是导航菜单的CSS
/*导航菜单*/ .guid_menu { text-align: center; margin: 5% 0 10% 0; width: 100%; } .subMenu { display: inline-block; color: #fff; text-align: center; padding: 2%; margin: 0 1%; border-radius: 5%; } .sub_bg1 { background-image: linear-gradient(-120deg, #c8d138, #51933b); } .sub_bg2 { background-image: linear-gradient(-120deg, #31c9a3, #107392); } .sub_bg3 { background-image: linear-gradient(-120deg, #4ccaf3, #326eea); } .sub_bg4 { background-image: linear-gradient(-120deg, #4a8fea, #1749bc); } .sub_bg5 { background-image: linear-gradient(-120deg, #5451e8, #611eb9); } .sub_bg6 { background-image: linear-gradient(-120deg, #bb3a8c, #ba6e3d); } .subMenu:hover { background: #cc0058; cursor: pointer; } .subMenu > p { margin: 8px 0; font-family: "宋体"; } .subMenu > p:first-child > i { font-size: 26px; } .subMenu > p:nth-child(2) { font-size: 18px; font-weight: bold; } .subMenu > p:nth-child(3) { font-size: 10px; color: rgba(255, 255, 255, 0.5); font-family: "Arial"; }
7.添加/编辑信息
<div class="layui-fluid" style="margin-top: 20px;"> <form class="layui-form layui-form-pane" lay-filter="component-form-group"> <div class="layui-card"> <div class="layui-card-header" style="font-weight: bold;text-align: center;">导航链接配置</div> <div class="layui-card-body" style="padding: 15px;"> <div class="layui-form-item"> <label class="layui-form-label">系统标题<span class="x-red">*</span></label> <div class="layui-input-inline"><input type="text" id="sys_title" name="sys_title" autocomplete="off" lay-verify="required" class="layui-input" value="科为数据可视化服务中心"></div> <label class="layui-form-label">英文标题<span class="x-red">*</span></label> <div class="layui-input-inline"><input type="text" id="sys_title_en" name="sys_title_en" autocomplete="off" lay-verify="required" class="layui-input" value="Kewei Data Visualization Service Center"></div> </div> <div class="layui-form-item"> <label class="layui-form-label">背景图片<span class="x-red">*</span></label> <div class="layui-input-inline"> <select name="sys_bg_img" id="sys_bg_img" class="layui-select"> <option value="./images/mainbg1.jpg" selected>mainbg1.jpg</option> <option value="./images/mainbg2.jpg" >mainbg2.jpg</option> <option value="./images/mainbg3.jpg" >mainbg3.jpg</option> </select> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">链接名称1<span class="x-red">*</span></label> <div class="layui-input-inline"><input type="text" id="title1" name="title1" autocomplete="off" lay-verify="required" class="layui-input" value="数据中心"></div> <label class="layui-form-label">链接地址1<span class="x-red">*</span></label> <div class="layui-input-inline"><input type="text" id="links1" name="links1" autocomplete="off" lay-verify="required" class="layui-input" value="https://www.baidu.com/"></div> </div> <div class="layui-form-item"> <label class="layui-form-label">链接名称2</label> <div class="layui-input-inline"><input type="text" id="title2" name="title2" autocomplete="off" class="layui-input" value="用户中心"></div> <label class="layui-form-label">链接地址2</label> <div class="layui-input-inline"><input type="text" id="links2" name="links2" autocomplete="off" class="layui-input" value="https://www.baidu.com/"></div> </div> <div class="layui-form-item"> <label class="layui-form-label">链接名称3</label> <div class="layui-input-inline"><input type="text" id="title3" name="title3" autocomplete="off" class="layui-input" value="后台管理"></div> <label class="layui-form-label">链接地址3</label> <div class="layui-input-inline"><input type="text" id="links3" name="links3" autocomplete="off" class="layui-input" value="https://www.baidu.com/"></div> </div> <div class="layui-form-item"> <label class="layui-form-label">链接名称4</label> <div class="layui-input-inline"><input type="text" id="title4" name="title4" autocomplete="off" class="layui-input" value="服务支持"></div> <label class="layui-form-label">链接地址4</label> <div class="layui-input-inline"><input type="text" id="links4" name="links4" autocomplete="off" class="layui-input" value="https://www.baidu.com/"></div> </div> <div class="layui-form-item"> <label class="layui-form-label">链接名称5</label> <div class="layui-input-inline"><input type="text" id="title5" name="title5" autocomplete="off" class="layui-input" value="产品概况"></div> <label class="layui-form-label">链接地址5</label> <div class="layui-input-inline"><input type="text" id="links5" name="links5" autocomplete="off" class="layui-input" value="https://www.baidu.com/"></div> </div> <div class="layui-form-item"> <label class="layui-form-label">链接名称6</label> <div class="layui-input-inline"><input type="text" id="title6" name="title6" autocomplete="off" class="layui-input" value="城市管理"></div> <label class="layui-form-label">链接地址6</label> <div class="layui-input-inline"><input type="text" id="links6" name="links6" autocomplete="off" class="layui-input" value="https://www.baidu.com/"></div> </div> <div class="layui-form-item"> <a class="layui-btn layui-btn-fluid layui-btn-normal" lay-filter="save" id="L_add" lay-submit=""><i class="layui-icon layui-icon-search"></i> 确定配置 </a> </div> </div> </div> </form> </div>
8.生成配置文件
$act = $_GET['act']; if ($act == "annual") { $sys_title = $_POST['sys_title']; $sys_title_en = $_POST['sys_title_en']; $sys_bg_img = $_POST['sys_bg_img']; $title1 = $_POST['title1']; $links1 = $_POST['links1']; $title2 = $_POST['title2']; $links2 = $_POST['links2']; $title3 = $_POST['title3']; $links3 = $_POST['links3']; $title4 = $_POST['title4']; $links4 = $_POST['links4']; $title5 = $_POST['title5']; $links5 = $_POST['links5']; $title6 = $_POST['title6']; $links6 = $_POST['links6']; //生成数据分表的配置文件config.sys.php $config_table = "<?php return [ 'sys_title' => '" . $sys_title . "', 'sys_title_en' => '" . $sys_title_en . "', 'sys_bg_img' => '" . $sys_bg_img . "', 'links' => [ ['title' => '" . $title1 . "','links' =>'" . $links1 . "'], ['title' => '" . $title2 . "','links' =>'" . $links2 . "'], ['title' => '" . $title3 . "','links' =>'" . $links3 . "'], ['title' => '" . $title4 . "','links' =>'" . $links4 . "'], ['title' => '" . $title5 . "','links' =>'" . $links5 . "'], ['title' => '" . $title6 . "','links' =>'" . $links6 . "'] ] ];"; //对应文件夹具备权限; @file_put_contents('conf/config.php', $config_table); $res['code'] = 1; $res['msg'] = "配置成功"; die(json_encode($res));
