window.open in javascript opens a new window (different name) in the original window_javascript skills

I recently made a JSP webpage that required opening IE without a menu toolbar, so I thought of using window.open to open it. However, I found that if the previously opened form is not closed, when opening a form, a new form will be opened on the previously opened form, so that the previous window will be replaced. After searching for information and testing, we found that if the form name specified when opening the form has the same name as the current form, it will be opened on that form. For example, the following situation:

window.open("view_svg.jsp?ukey=&itemID=&charset=UTF-8","newWindow","height='100%' , width='100%',toolbar=no,location=no,directories=no,menubar=no,scrollbars=no,resizable=no,status=no");
Each form opened in this way is opened in a form named newWindow.

Note: The name and title of the form are different.

1.window.open(urlStr,'_blank','');

_blank parameter means opening a new window.

2. You can also use the following method to make the window have a different name each time it is opened.

<%
Random rd = new Random();
int i = rd.nextInt(100)+1;
String ranStr = String.valueOf(i);
%>
<script type="text/javascript">
function doclose(){
 var currnwin = window.open("view_svg.jsp&#63;ukey=<%=ukey%>&itemID=<%=itemID%>&charset=UTF-8","<%=ranStr%>","height='100%', width='100%',toolbar=no,location=no,directories=no,menubar=no,scrollbars=no,resizable=no,status=no");
window.opener=null;
 window.close();
 window.focus();
}
</script>

Now I will introduce to you how to use javascript window.open to open a new window

The open() method can find an existing or newly created browser window.

Grammar:

window.open([URL], [window name], [parameter string])
