window.open opens a link to modify the window title

At the beginning, I wanted to use the simplest method to achieve

let test = window.open('www.baidu.com') 
test.onload = function () { 
    test.document.title = menu.menuName 
}

or

let test = window.open('www.baidu.com') 
setTimeout(()=>{
  test.document.title = menu.menuName
})

But there will be cross-domain problems, and the title cannot be modified

In order to solve the cross-domain problem and realize the requirement of modifying the title, use iframe to realize

openNewWindow(path, name);
function openNewWindow(url, title) {
   const win = window.open('about:blank');
   win.document.title = title;
   const iframe = document.createElement('iframe');
   iframe.src = url;
   iframe.style.width = '100%';
   iframe.style.height = '100vh';
   iframe.style.margin = '0';
   iframe.style.padding = '0';
   iframe.style.overflow = 'hidden';
   iframe.style.border = 'none';
   win.document.body.style.margin = '0';
   win.document.body.appendChild(iframe);
}

Use this method to successfully implement the need to change the browser title and solve cross-domain problems
