The window object is one level higher than the document object in the JavaScript object hierarchy. | |
The window object can manipulate the current window as well as create new window instances. | |
If window B is created by window A, window B is considered a child of window A. | |
| |
The name of the child window is "myChild". | |
Any values in the child window are referenced using the name of the parent window. | |
The parent has total control of its immediate child window and any subsequent child (grandchild) windows. | |
If the parent window is destroyed, all control for the remaining child windows is lost. | |
A child window can find out who its parent is by using the opener method. | |
You use the opener method as shown in the following: | |
| |
This will return the name of the parent document to the name variable. | |
You can use multiple instances of opener if you have several levels of windows. | |
If a grandchild wanted to reference its grandparent, it could do so by simply adding another level. | |
| |
For a window to refer to its own properties, you can use the window self property. | |
Suppose you wanted to set a textbox value within a form document in a window. | |
