about button.addEventListener

If there are about 10 buttons and the buttons are numbered from 1 to 10, if button 1 is clicked, object 1 is created. If button 2 is clicked, object 2 is created and the remaining objects 1, 3 and 4 are deleted. I want to become In the present case, it is implemented by hard coding, but I want to keep this code neat and short. Help.

this is my code

document.getElementById("leg_type2").addEventListener("click",
  function() {
    Group1.children[1].visible = !Group1.children[1].visible;
    Group1.children[0].visible = false;
    Group1.children[2].visible = false;
    Group1.children[0].scale.set(0, 0, 0)
    Group1.children[1].scale.set(1, 1, 1)
    Group1.children[2].scale.set(0, 0, 0)
  });

document.getElementById("leg_type3").addEventListener("click",
  function() {
    Group1.children[2].visible = !Group1.children[2].visible;
    Group1.children[1].visible = false;
    Group1.children[0].visible = false;
    Group1.children[0].scale.set(0, 0, 0)
    Group1.children[1].scale.set(0, 0, 0)
    Group1.children[2].scale.set(1, 1, 1)
  });

Answer

You can create a function that does this work for you:

document.getElementById("leg_type2")
  .addEventListener("click", function () { toggle(2); });

document.getElementById("leg_type3")
  .addEventListener("click", function () { toggle(3); });

function toggle(index) {
  const { children } = Group1;

  for (let i = 0; i < children.length; i++) {
    if (i !== index) {
      children[i].visible = false;
      children[i].scale.set(0,0,0);
    }
  }

  children[index].visible = true;
  children[index].scale.set(1, 1, 1);
}
