JavaScript setTimeout setInterval within one function

anonymous-function, javascript, setinterval

Solution

it cannot work because because your `setInterval` will be called AFTER the timeout! your original approach is correct and you can still wrap this into single function:

var dotime=function(){
  var iv = setInterval(function(){
    sys.puts("interval");
  }, 1000);
  return setTimeout(function(){
    clearInterval(iv);
  }, 5500);
};

Problem

I think I might be overtired but I cannot for the life of me make sense of this, and I think it's due to a lack of knowledge of javascript ``` var itv=function(){ return setInterval(function(){ sys.puts('interval'); }, 1000); } var tout=function(itv){ return setTimeout(function(){ sys.puts('timeout'); clearInterval(itv); }, 5500); } ``` With these two functions I can call ``` a=tout(itv()); ``` and get a looping timer to run for 5.5 seconds and then exit, essentially. By my logic, this should work but it simply is not ``` var dotime=function(){ return setTimeout(function(){ clearInterval(function(){ return setInterval(function(){ sys.puts("interval"); }, 1000); }); }, 5500); } ``` any insight in this matter would be appreciated.
