Recently, I made a jsp webpage to open an Internet Explorer without menu bar. I thought of using window.open to open it. But found that if the previously opened form was not closed,When a form is opened, a new form is opened on a form that was not previously closed,The previous window is replaced.After searching the information and testing, it is found that if the specified form name and the current form have the same name when opening the form, it will be opened on that form.For example:

window.open ("view_svg.jsp?ukey =<%= ukey%>&itemid =<%= itemid%>&charset=utf-8", "newwindow", "height =" 100%",, toolbar=no, location=no, directories=no, menubar=no, scrollbars=no, resizable=no, status=no ");

Each window opened in this way is opened in a window named newwindow.

Note:The name of the form is different from the title.

1.window.open (urlstr, "_ blank", "");

The _blank parameter indicates that a new window is opened.

2. You can also use the following method to make the form open differently each time.

<%
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?ukey =&%;uke =%>&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>
