Question

I need to let a piece of code always run independently of other code. Is there a way of creating a thread in javascript to run this function?

–why setTimeout doesn’t worked for me

I tried it, but it runs just a single time. And if I call the function recursively it throws the error “too much recursion” after some time. I need it running every 100 milis (it’s a communication with a embedded system).

–as you ask, here goes some code

function update(v2) {
     // I removed the use of v2 here for simplicity
     dump("update\n"); // this will just print the string
     setTimeout(new function() { update(v2); }, 100); // this try doesn't work
}
update(this.v);

It throws “too much recursion”.

Answer 1

Get rid of the new keyword for the function you’re passing to setTimeout(), and it should work.

function update(v2) {
 try {
     dump("update\n");
 } catch(err) {
     dump("Fail to update " + err + "\n");
 }
 setTimeout(function() { update(v2); }, 100);
}
update(this.v);

Or just use setInterval().

function update(v2) {
 try {
     dump("update\n");
 } catch(err) {
     dump("Fail to update " + err + "\n");
 }
}
var this_v = this.v;
setInterval(function() {update(this_v);}, 100);

EDIT: Referenced this.v in a variable since I don’t know what the value of this is in your application.
