How can I pass a parameter to a setTimeout() callback?

Question

I have some JavaScript code that looks like:

function statechangedPostQuestion()
{
  //alert("statechangedPostQuestion");
  if (xmlhttp.readyState==         


        

Answer 1

// These are three very simple and concise answers:

function fun() {
    console.log(this.prop1, this.prop2, this.prop3);
}

let obj = { prop1: 'one', prop2: 'two', prop3: 'three' };

let bound = fun.bind(obj);

setTimeout(bound, 3000);

 // or

function funOut(par1, par2, par3) {

  return function() { 

    console.log(par1, par2, par3);

  }
};

setTimeout(funOut('one', 'two', 'three'), 5000);

 // or

let funny = function(a, b, c) { console.log(a, b, c); };

setTimeout(funny, 2000, 'hello', 'worldly', 'people');
