Show us what you have tried and tell us what doesn't work
Dear Sir :
It just a idea.
I hope it like C,below :
if(button==0) flag=1;
else flag=0;
Thank u.
better if you can read the documentation. You will come up with better idea.
Dear Sir :
Ok,I will try to understand...
Thank u.
That should work, assuming that button
is the variable you want to test and you want to set the value of an already declared variable flag
For basic javascript help the w3schools site is good. JavaScript Tutorial

Dear Sir :
I will read the information from the w3schools.
Thank u.
^= is a bitwise XOR assignment
flag = flag XOR 1

Is that really what you are trying to do?
Why?
Dear jbudd :
If I want to control LED is on/off,
Should to do like that...
But flag^=1; (not correct, why?)
Cause Let flag=0; ??? So How can I to initial flag in right place?
Thank u.
Your button can send a number (0 or 1), a boolean (true or false), a string ("ON" or "OFF").
Make it send the datatype that you need to control the LED and get rid of the function node.
Dear jbudd :
But the ui_button just can only true or false!
Thank u.

Note the "When clicked send:" setting at the bottom of this shot
Again, as per your other thread, you need to use context to hold the existing flag state, as @knolleary showed you.
Dear All Sir : Thanks for ur reply...
ok, I see.
And hv a question to I need to ask knolleary...
Thanks All Sir again.
Dear dceejay :
Sorry..., Here again. Still cant be correct! at pic and below :
Thank u.
You return msg
inside the if
block - which means the context.set()
line at the end does not get called,
Move the context.set
line to just before the return msg
line.
Dear knolleary :
Oh, I see, Im so so so stupid..haha.
Thank u very much.
