Question

I’m trying to figure out how to generate functions inside for loop.
I have:

for (var i = fir_0_f.length - 1; i >= 0; i--){
  var next = i+1;
  var N = i;
  // Attemps
      //goal0_[i](next,N);
      //eval('goal0_'+i+'('+next+', '+N+')');
}; 

Have done also some searching. [] expects a string, eval() is a B.A.D practice. Is there any other way?
How to set the timeout for each function later? So they would run sequentally?

Thanks a lot!

Answer 1

for (var i = fir_0_f.length - 1; i >= 0; i--){
  var next = i+1;
  var N = i;
  setTimeout('goal0_'+i+'('+next+','+N+')', 0);
}

Note: errors thrown by goal0_i won’t be caught by the loop.
I’ve noticed this behavior in Firefox.
That means that the following won’t work as you expected:

try{
   setTimeout(function_throwing_error, 0);
}
catch(e){
   alert("I kill you!");
}
