Functionblock status
For a single status
// Single status notification
node.status({text:msg.payload});
// Multiple status notifications
node.status({ text: flow.get('Loop') + " " + msg.payload});
return msg;
TIME
msg.payload = Date.now(); > Unix time msg.payload = Date(); > Readable date and time
Divide long code in multiple lines
After a function you can start a new line.
var var1 = true;
var var2 = false;
if (var1 === true &&
var2 !== true) {
msg.payload = true;
}
return msg;
Conversion between number and string
"function node" // Number to string msg.payload = String(msg.payload); return msg; // OR // String to number msg.payload = Number(msg.payload); return msg;
If with multiple conditions
"function node"
var var1 = true;
var var2 = false;
if (var1 === true && var2 === !true) {
msg.payload = true;
}
return msg;
// && = AND
// || = OR
// ! = NOT
Output True Only (Function)
"Code in function node"
if (msg.payload===true){
return msg;
}
Output on change only (Function)
"Code in function node"
var payload_prev=context.get('payload_prev') || false;
if (msg.payload !== payload_prev){
payload_prev=context.set('payload_prev',msg.payload);
return msg;
}
Delay with variable time and reset (Example)
"Code in function node"
if (msg.payload===true){
return msg;
}
if (msg.payload===false){
msg.reset=true;
return msg;
}
if (msg.topic === "delay"){
msg.delay=2000;
msg.payload = true;
return msg;
