ie8 var w window open - Message Invalid argument

Question

I have a site that has an IE8-only problem   The code is    var w   window open urlstring  wname  wfeatures   false      The error is      Message  Invalid argument    Line  419    Char  5   Code  0   URI  http   HOSTNAME js context js   I have confirmed the line number of the code  the  Line  and  URI  are correct   and I understand in later versions of IE8  this is considered accurate   I have checked all the incoming parameters in the call by dumping alerts  and they all look valid   This problem does not happen on FF  probably 3    UPDATE   The problem appears to be in using assigning the result of window open   when doing  var w   When I split the line into two statements it works in IE8   UPDATE2    Based on    http   javascript crockford com code html     When a function is to be invoked   immediately  the entire invocation   expression should be wrapped in parens   so that it is clear that the value   being produced is the result of the   function and not the function itself    This is not exactly what is going on here  but I found that applying the principle solved the problem  in IE8 s compatability mode   var w    window open urlstring  wname  wfeatures  false

This is an old posting but maybe still useful for someone.

I had the same error message. In the end the problem was an invalid name for the second argument, i.e., I had a line like:

   window.open('/somefile.html', 'a window title', 'width=300');

The problem was 'a window title' as it is not valid. It worked fine with the following line:

   window.open('/somefile.html', '', 'width=300');

In fact, reading carefully I realized that Microsoft does not support a name as second argument. When you look at the official documentation page, you see that Microsoft only allows the following arguments, If using that argument at all:

_blank
_media
_parent
_search
_self
_top

Try remove the last argument  Other than that  make sure urlstring  wname  and wfeatures exist

It seems when even using a  valid  custom window name  not  blank  etc   using window open to launch a new window  there is still issues  It works fine the first time you click the link  but if you click it again  with the first launched window still up  you receive an  Error  No such interface supported  script debug

The answers here are correct in that IE does not support spaces when setting the title in window open    none seem to offer a workaround   I removed the title from my window open call  you can use null or      and hten added the following to the page being opened    lt script gt document title    My new title   lt  script gt    Not ideal by any means  but this will allow you to set the title to whatever you want in all browsers

I discovered the same problem and after reading the first answer that supposed the problem is caused by the window name  changed it   first to   blank   which worked fine  both compatibility and regular view   then to the previous value  only minus the space in the value    - also worked  IMO  the problem  or part of it  is caused by IE being unable to use a normal string value as the wname  Hope this helps if anybody runs into the same problem

the problem might be the wname  try using one of those shown in the link above  i quote      Optional  String that specifies the   name of the window  This name is used   as the value for the TARGET attribute   on a form or an anchor element           blank The sURL is loaded into a new  unnamed window     media The url is loaded in the Media Bar in Microsoft Internet   Explorer 6     Microsoft Windows XP   Service Pack 2     SP2  and later    This feature is no    longer   supported  By default the url    is   loaded into a new browser window    or   tab     parent The sURL is loaded into the current frame s parent  If the frame    has no parent  this value acts as the    value  self     search Disabled in Windows Internet Explorer 7  see Security and Compatibility in Internet Explorer 7 for details  Otherwise  the sURL is opened in the browser s search pane in Internet Explorer 5 or later     self The current document is replaced with the specified sURL     top sURL replaces any framesets that may be loaded  If there are no framesets defined  this value acts as the value  self       if using another wname  window open won t execute

When you call window open in IE  the second argument  window name  has to be either one of the predefined target strings or a string  which has a form of a valid identifier in JavaScript   So what works in Firefox   Job Directory 9463460   does not work in Internet Exploder  and has to be replaced by   Job Directory 9463460  for example  no spaces  no minus signs  no dots  it has to be a valid identifier

For me the issue was with a dash  -  in the window name field  I removed the dashes and IE does not error out and in fact opens the window

IE is picky about the window name argument  It doesn t like spaces  dashes  or other punctuation

[javascript] ie8 var w= window.open() - "Message: Invalid argument."
