    Two ways of opening a new window

    What's the difference between the two ways of opening a new window and
    writing to it?

    Let's say I prepare a code that goes into a new window and save it in a
    variable winHTML:

    var winHTML = "<HTML><HEAD><T ITLE>Any title</TITLE><BODY>Any
    text</BODY></HEAD>";

    Now, I have two ways to open a new window and write that code into the new
    window:

    One way is:
    var newWin=window.o pen();
    newWin.document .open();
    newWin.document .write(winHTML) ;
    newWin.document .close();
    newWin.focus();

    Other way is:
    window.open("ja vascript:opener .winHTML");

    Is there any reason why to prefer one over the other?

      ...perhaps you should validate that as HTML first.

          var winHTML = "<HTML><HEAD><T ITLE>Any title</TITLE><BODY>Any
          text</BODY></HTML>";

          However, the JavaScript question was as clear as it is now. I wouldn't
          attach too much importance to minor HTML errors, unless I present a question
          that requires running a code.

              I routinely use the second. The window.open() method returns
              without guaranteeing that the window has been created yet, so
              there have been many posts to this newsgroup asking why that
              method fails some of the time.

              I've never had any trouble with the second form.
              That sort of thing is exactly what the "javascript :"
              pseudo-protocol was created for.

              note that you can send focus to the window (as you do in your
              first example), with:

              window.open("ja vascript:opener .winHTML").focu s();

                  Nothing has changed, this is still invalid HTML. Besides, the ETAGO
                  delimiters (</) can cause trouble as it marks the end of the element in
                  SGML. If you use that sequence in scripts embedded in HTML documents,
                  escape it. In J(ava)Script you would do that with "<\/".

                  You can't build a house on a swamp.

                  And please, trim your quotes and use a "From" header
                  that complies with Internet/Usenet standards.
