For the window object, opens a new web browser window. xxx For the document object, description to be supplied.
Syntax
The first form of the syntax is for the document object; the second form is for window.
1. document.open("MIME type") 2. window.open("URL", "windowName", ["windowFeatures"])URL specifies the URL to open in the new window.
windowName specifies a name for the window object being opened.
windowFeatures is a comma-separated list of any of the following options and values:toolbar[=yes|no]|[=1|0] location[=yes|no]|[=1|0] directories[=yes|no]|[=1|0] status[=yes|no]|[=1|0] menubar[=yes|no]|[=1|0] scrollbars[=yes|no]|[=1|0] resizable[=yes|no]|[=1|0] copyhistory[=yes|no]|[=1|0] width=pixels height=pixels
You may use any subset of these options. Separate options with a comma. Do not put spaces between the options.
pixels is a positive integer specifying the dimension in pixels.
NOTE: In event handlers, you must specify window.open() unless you want to call document.open() because of the scoping of static objects in JavaScript.
Description for window
The open method opens a new web browser window on the client, similar to choosing File|New Web Browser from the menu of the Navigator. The URL argument specifies the URL contained by the new window. If URL is an empty string, a new, empty window is created.
windowFeatures is an optional, comma-separated list of options for the new window. The boolean windowFeatures options are set to true if they are specified without values, or as yes or 1. For example, open("", "messageWindow", "toolbar") and open("", "messageWindow", "toolbar=1") both set the toolbar option to true. If windowName does not specify an existing window and you do not specify windowFeatures, all boolean windowFeatures are true by default.
Following is a description of the windowFeatures:
- toolbar creates the standard Navigator toolbar, with buttons such as "Back" and "Forward", if true
- location creates a Location entry field, if true
- directories creates the standard Navigator directory buttons, such as "What's New" and "What's Cool", if true
- status creates the status bar at the bottom of the window, if true
- menubar creates the menu at the top of the window, if true
- scrollbars creates horizontal and vertical scrollbars when the document grows larger than the window dimensions, if true
- resizable allows a user to resize the window, if true
- copyhistory gives the new window the same session history as the current window, if true
- width specifies the width of the window in pixels
- height specifies the height of the window in pixels
Description for document

It opens it with the specified option settings and names the corresponding window object newWin.
<FORM NAME="myform"> <INPUT TYPE="button" NAME="Button1" VALUE="Open Sesame!" onClick="window.open('sesame.html', 'newWin', 'toolbar=no,directories=no,menubar=no,status=yes,width=300,height=300')"> </form>Notice the use of single quotes (') inside the onClick event handler.

parse method
Syntax
Date.parse(date string)
Description
The parse function takes a date string (such as "Dec 25, 1995"), and returns the number of milliseconds since January 1, 1970 00:00:00 (local time). This function is useful for setting date values based on string values, for example in conjunction with the setTime method.
Given a string representing a time, parse returns the time value. It accepts the IETF standard date syntax: "Mon, 25 Dec 1995 13:30:00 GMT". It understands the continental US time zone abbreviations, but for general use, use a time zone offset, for example "Mon, 25 Dec 1995 13:30:00 GMT+0430" (4 hours, 30 minutes west of the Greenwich meridian). If you do not specify a time zone, the local time zone is assumed. GMT and UTC are considered equivalent.
The parse function is a static method of Date. That means that you always use it as
Date.parse(), rather than as a method of a date object you created.Applies to
Examples
If IPOdate is an existing date object, then
IPOdate.setTime(Date.parse("Aug 9, 1995"))See also

The following statement creates a date object using GMT instead of local time:
gmtDate = new Date(Date.UTC(96, 11, 1, 0, 0, 0))
