Problems with setTimeout()

[brbaltes]

I am currently having problems with the setTimeout() command in a module.  It executes when testing but there is no delay where the setTimeout() command is called.  Any help would be greatly appreciated!

   module.setSource = function(source)

   {

  module.sendCommand('SOURCE ' + Epson8700UBTables.Sources.Commands[source]);

  setTimeout(module.requestSource(), 3000);

   };

 

   module.requestSource = function()

   {

  module.sendCommand('SOURCE?');

   };

Instead of passing the function to setTimeout, you are _executing_ the function with module.requestSource(). This is a common oversight. Here is the proper syntax:

> setTimeout(module.requestSource, 3000);

Notice the remove parenthesis. Tiny change makes a big difference :-)

Florent, 

When we call setTimeout, it seems that while in that timeout, we are unable to receive feedback. Is this because JavaScript is single threaded and execution is stopped in the timeout, or are we doing something wrong?

Thanks!

I don't see what you're mentioning in that code. The function you are executing in setTimeout simply does a sendCommand(), so there should not be any issue. If you don't get feedback (but again I have not seen the whole code) there may be another issue somewhere else.

What would I do for setting a timeout on a function that passes parameters? Like module.getTie(output, "both")

[Jarrod Bell]

Something like:

setTimeout(module.getTie, 1000, output, "both");
