The Doc Dialer: A Final Word

The Doc Dialer

A Final Word

In this column we introduced a new application, The Doc Dialer. The current version works for Internet Explorer only, but future versions will support other browsers/platforms as well. We showed you how the device works and explained in detail the Presidents example that we have implemented. We went over the code and explained the main trie algorithm for extracting data elements according to the index so far. We also introduced a new feature of Internet Explorer 5.5, the replace() function. Be sure to check our next columns for more reviews of the new features of Internet Explorer 5.5.

In this column, you learned:

• How to create a trie data structure
• How to store the president names in the Trie Phone

• How to implement the phone keypad
• How to handle a button click
• How to collect data entries down the trie
• How to display the matched names

We also included the listing of our DOCJS Trie Phone and its zipped version.
