JavaScript FAQ - Console

'JavaScript FAQ - Console' +'' +content +'' ) top.consoleRef.document.close() } //-->

writeConsole('Hello from JavaScript!');
function writeConsole(content) {
 top.consoleRef=window.open('','myconsole',
  'width=350,height=250'
   +',menubar=0'
   +',toolbar=1'
   +',status=0'
   +',scrollbars=1'
   +',resizable=1')
 top.consoleRef.document.writeln(
  '<html><head><title>Console</title></head>'
   +'<body bgcolor=white onLoad="self.focus()">'
   +content
   +'</body></html>'
 )
 top.consoleRef.document.close()
}

In the above example, you might notice that after you write something to the console several times, the console window will allow you to navigate back and forth in the output's history. This is not always a desired feature. If you would like to output the new content without creating a new history entry, add the following operator after opening the window (and before the first write):

docRef = top.winRef.document.open("text/html","replace");

Here winRef is the window reference returned by the window.open() method, and docRef is a global variable in which the script stores the reference to your new document.
