Window.location.href(url)。如何捕获url的成功事件

function redirectTo(url, callback) {
  window.location.href = url;
  window.onload = function() {
    callback();
  };
}

redirectTo("https://www.example.com", function() {
  console.log("URL跳转成功");
});

window.addEventListener("load", function() {
  console.log("URL跳转成功");
});

window.location.href = "https://www.example.com";

function redirectTo(url) {
  return new Promise(function(resolve, reject) {
    window.location.href = url;
    window.onload = function() {
      resolve();
    };
  });
}

redirectTo("https://www.example.com")
  .then(function() {
    console.log("URL跳转成功");
  });
