Finding Values and More with Web Page Dialog Boxes

If you are carrying out such a project for commercial purpose, then there are certain things you will have to take into consideration.

First of all, let us see how to close a window. The statement to close the current window (the window JavaScript resides in) is:

window.close();

For a window to close another window, use the following statement:

winRef.close();

where winref is the reference to the other window.

To know whether a window is closed, use the following statement:

winRef.closed

This statement returns true if the window is closed; otherwise, it returns false. You can use it in an if-block as follows:

If (winRef.closed)

{

//do something

}

You can add code such that all the windows can be closed from the main window. You can also add code such that no intermediate dialog box is closed unless it is at the bottom end of the chain. I have given you the principles to do these.

Projects like this often involve a database. You can add code such that data can be sent from any dialog box to the database.

Conclusion

We are in the era of web development. Web development involves a database at one end, the Internet and the browser in the client computer at the other end. Depending on your project, you will need dialog boxes for a web (browser) window. The principles I have outlined here will lead you through.
