Javascript window.open a solution to a problem where a new window cannot be opened again

Javascript open window is used in some places on the system. For example, open a window in fixed mode to prevent the user from doing anything else.

innerWidth | pixel value |  The pixel width of the document in the window  
location | yes/no |  Whether the position bar is visible  
menubar | yes/no |  Is the menu bar visible

Example:

window.open("page.html", "newwindow", "height=100, width=100, top=0,left=0,toolbar=no, menubar=no, scrollbars=no,resizable=no, location=no, status=no")

After calculating the height and width according to the resolution, open:

var ht = screen.height-98;
var widhh = screen.width - 20;
window.opener = null;
window.open("", "_self");
window.open("Main.aspx", "newwindow" + JsGuid(),
"height=" + ht + ", width=" + widhh + ",
depended=yes,top=0,left=0,toolbar=no, menubar=no,
 scrollbars=yes, resizable=no, location=no, status=yes");

window.close();

And close the original window.

Question:

If the system exits after window.open, an error occurs when you open a new page using window.open again.

Google for a long time also did not find. One thing that should not happen very often is definitely a configuration problem.

Where we can see that the second argument to window.open is the name of the new window. The name cannot be repeated.

If it repeats, it will always refresh in this window.

So I added a random GUID function of js.

function s4() {
    return Math.floor((1 + Math.random()) * 0x10000)
               .toString(16)
               .substring(1);
};
function JsGuid() {
    return s4() + s4() + '-' + s4() + '-' + s4() + '-' +
           s4() + '-' + s4() + s4() + s4();
}

Window.open (" main.aspx ", "newwindow" + JsGuid());
OK, problem solved.
