The node-red-contrib-cool-loop package provides two nodes for Node-RED: cool-loop-start and cool-loop-join. These nodes work together to process an array of elements one by one through a user-defined flow, using events to coordinate continuous execution....
nodered循环loop案例 一、介绍Node-RED循环loop的概念 Node-RED是一个基于Node.js运行时的开源可视化编程工具，可用于连接物联网设备、API和上线服务。Node-RED的循环loop是一种循环控制结构，允许用户创建重复执行特定任务的流程。循环可以通过条件判断或者固定次数来控制执行次数，能够帮助用户简化流程逻辑，提高编程效率...
you return an array of messages in the output message array. Listing 5.15 shows how to write a function that returns 10 new messages containing number payloads from 0 to 9. Line 1 creates a new array, msgList, to hold the messages. Lines 2 and 3 loop 10 times adding a new ...

Same as calling elements(); implemented so that convenience "for-each" loop can be used for looping over elements of JSON Array constructs. long longValue() Returns 64-bit long value for this node, if and only if this node is numeric (isNumb...
use this.send({}) to pass result to Node-RED. (to avoid a loopback addui_control.callback="someText")this.send({topic: "anyTopic",payload:"anyPayload",ui_control: {callback:"myCallback"}});all parameters are named according to tabulator documentation. Use field instead of Property ...
For those using Red Hat Enterprise Linux (RHEL), Node.js support will start after the release is promoted to LTS in October, which means you can expect to find packages for the RPM Package Manager (rpm) and containers around that time. However, to facilitate advanced testing, the Red Hat...
