如何制作新的按钮链接网页?

var modal = document.getElementById("ID-modal");
var btnn = document.getElementsByClassName("goto-item")[0];
var span = document.getElementById("modal-cancel");
const modal_complete = document.getElementById("modal-complete");
var goto_content = document.querySelector(".goto-content");
const DEFAULT = "";

btnn.onclick = function() {
  modal.style.display = "block";
}

span.onclick = function() {
  modal.style.display = "none";
}

function addBtn() {
  var text_1 = document.getElementById("modal-text1").value;
  var text_2 = document.getElementById("modal-text2").value;
  if (text_1 == "" || text_2 == "") {
    btn_off();
  } else {
    modal_complete.setAttribute('disabled', 'false');
    var newBtn = document.createElement("input");
    newBtn.type = "button";
    newBtn.value = text_1;
    goto_content.appendChild(newBtn);
    newBtn.setAttribute("onclick", goWeb(text_2));
    modal.style.display = "none";
  }
}

function goWeb(text_2) {
  location.href = text_2;
}
