Why is setTimeout executing immediately? [duplicate]

Question

I have a simple JavaScript setTimeout function, but it is refusing to work

setTimeout(timeup(tc,chosen),10000)

... and this is the function:

timeup = function (clt,clo)
{   
    alert("time up")
}

... and the time up alert shows up immediately instead of after 10 seconds can someone tell me why this is happening please?

Answer 1

because you're actually calling the timeup(tc,chosen) function inside the setTimeout function.

try:

setTimeout(function(){
  timeup(tc,chosen);
}, 10000);
