Windows & Frames in JavaScript

Creating a new window

This can also be done in HTML using an A HREF link tag and setting the TARGET attribute to "self". However, JavaScript will additionally allow you to set attriutes for the new window.

windowObject = window.open ("URL", "Name of window", "Features list");

The features list is a list of optional window attributes. If not set the default values will be used.

• width
• height
• toolbar
• location
• directories
• status
• menubar
• scrollbars
• resizable

Timeouts

A Timeout allows one to get a script to do something for a specified amount of time. The window.setTimeout method allows specification of a time delay where a command will be executed after that period of time has passed.

ident = window.setTimeout ("alert ('Time's up !')", 10000);

Before a Timeout has elapsed that Timeout can be halted with window.clearTimeout (ident);

Dialog boxes

• window.alert - OK button display
• window.confirm - OK & Cancel buttons giving true & false respectively
• window.prompt - return text entered by the user
