将函数作为参数传递并在setInterval中用于javascript

Question

I am trying to pass a function as a parameter to other function and use that parameter in setInterval but for some reason it is not working.

function x(){
  var x1 = "parameter1";
  var y1 = "parameter2";
  y(parameter1,prameter2,function(){
      alert(y1);
  });
}
function y(parameter1,parameter2, func){
 //some code
 setInterval(func,1000);
}

After executing x it should display alert box every 1 second but it does not can you please help

PS: If I call func from y using func() it works well

Answer 1

Replace your passed parameters in function y as x1, y1

Because you have to pass variables

function x(){
  var x1 = "parameter1";
  var y1 = "parameter2";
  y(x1,y1,function(){  //Replace your passed parameters here as x1, y1
      alert(y1);
  });
}
function y(parameter1,prameter2, func){
 //some code
 setInterval(func,1000);
}
