36 <h1>document.write (out-of-line) test</h1>
37 <p>This test uses the open, write and close methods of a
38 document to construct a document. It tests the "out-of-line"
39 capabilities of document.write i.e. the ability to use
40 document.write to create an entirely new document.</p>
42 <form>
43 <p>Use this button to create a new window. If one already
44 exists, we'll use it.
45 <INPUT TYPE="button" NAME="newwin" VALUE="New Window" onClick="newWin(); return true;">
46 </p>
48 <p>Use this button to write the new value of a counter into
49 the document. If the document was previously closed, it will be
50 reopened (and the old contents will be destroyed.
51 <INPUT TYPE="button" NAME="incrwrite" VALUE="Write" onClick="incrWrite(); return true;">
52 </p>
54 <p>Use this button to close the document. Subsequent writes will rewrite
55 the document.
