node-red教程之dashboard简介与输入型仪表板控件的使用

既然你想了解“node-red教程之dashboard简介与输入型仪表板控件的使用”的完整攻略，我将会为你详细介绍。

1. 什么是Node-RED Dashboard

Node-RED Dashboard 是一个能够帮助用户可视化呈现数据的用户界面框架。它是一款基于 Node-RED 的 UI 组件库，提供了基础（tab/panel/widget）和输入型（button/switch/slider）等多种控件，且都是基于 AngularJS 编写而成，同时也是开放式的，能够根据用户的需求进行自定义开发。

2. Node-RED Dashboard 如何完成输入型仪表板控件的使用

在 Node-RED 中，dashboard 的构建十分简单，只需要通过 npm 安装 node-red-dashboard 模块，并在 Node-RED 界面中添加 Dashboard 节点，即可进入 Dashboard 的设置页面，那么掌握了基础的构建与设置，我们可以来尝试使用具体的控件了。

3. Button 控件的使用

Button 控件是一个可以执行某些逻辑操作的简单按钮。想要实现它的事件，只需要通过设置其 msg.payload 参数的值即可。例如，你可以将 msg.payload 设置为 true 来执行命令，或将 msg.payload 设置为 false 来停止某个进程。

以下这是一个示例代码：

[{"id":"5a3d73fc.bd761a","type":"ui_button","z":"ffbc8f07.68a968","name":"","group":"f6c0b80b.348fd8","order":4,"width":0,"height":0,"passthru":false,"label":"button","tooltip":"","color":"","bgcolor":"","icon":"","payload":"true","payloadType":"bool","topic":"","x":210,"y":280,"wires":[["f0072a7f.902848"]]},{"id":"f0072a7f.902848","type":"debug","z":"ffbc8f07.68a968","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":410,"y":280,"wires":[]},{"id":"f6c0b80b.348fd8","type":"ui_group","z":"","name":"Default","tab":"8cd6cf4d.afc978","order":1,"disp":true,"width":"6","collapse":false},{"id":"8cd6cf4d.afc978","type":"ui_tab","z":"","name":"Home","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

4. Slider 控件的使用

Slider 控件是一个滑块控件，它允许你进行精细的调整或设置某个数值范围。你可以通过它来实现 volume（音量）和 brightness（亮度）等操作。

以下这是一个示例代码：

[{"id":"2043807f.3d9d92","type":"ui_slider","z":"ffbc8f07.68a968","name":"","label":"slider","tooltip":"","group":"f6c0b80b.348fd8","order":2,"width":0,"height":0,"passthru":true,"outs":"end","topic":"","min":0,"max":10,"step":1,"x":220,"y":360,"wires":[["f0072a7f.902848"]]},{"id":"f0072a7f.902848","type":"debug","z":"ffbc8f07.68a968","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":410,"y":280,"wires":[]},{"id":"f6c0b80b.348fd8","type":"ui_group","z":"","name":"Default","tab":"8cd6cf4d.afc978","order":1,"disp":true,"width":"6","collapse":false},{"id":"8cd6cf4d.afc978","type":"ui_tab","z":"","name":"Home","icon":"dashboard","order":1,"disabled":false,"hidden":false}]
