In the system, javascript open window is used in some places. For example, opening a fixed-mode window prevents users from performing other operations.

Example:

Copy code The code is as follows:

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")

Open after calculating the height and width according to the resolution:

Copy codeThe code is as follows:

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:

After window.open, if the system exits, an error will occur when using window.open to open a new page again.

I googled for a long time and couldn’t find it. Thinking that this problem should not happen often, it must be a configuration problem.

Among them, we can see that the second parameter of window.open is the name of the new window. This name cannot be repeated.

If it is repeated, keep opening and refreshing this window.

So I added a js random GUID function.

Copy code The code is as follows:

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

Use: window when opening a window .open("Main.aspx", "newwindow" JsGuid());
OK, the problem is solved.
