Data and development features
ColdFusion data and development features help you develop effective Ajax applications that use ColdFusion to
provide dynamic data. They include many features that you can use with other Ajax frameworks, including Spry.
The following data and development features are important for use with form and layout tags:
• ColdFusion supports data binding in many tags. Binding allows form and display tags to dynamically display
information based on form input. In the simplest application, you display form data directly in other form fields.
But usually, you pass form field data as parameters to CFC or JavaScript functions or CFM pages, and use the results
to control the display.
• The
tag specifies the location of the JavaScript and CSS files that a ColdFusion page imports or to
cfajaximport
selectively import files required by specific tags. The ability to change the file location lets you support a wide range
of configurations and use advanced techniques, such as application-specific styles.
For more information about the data and development features and how to use them, see
Development Features" on page 858.
User Interface tags and features
Several ColdFusion user interface elements incorporate Ajax features. The tags and tag-attribute combinations can be
divided into the following categories:
• Container tags that lay out or display contents
• File management tags that handle files
• Form tags that dynamically display data
• A menu tag that lets you create menu bars and pull-down menus
• User assistance features that provide tool tips and form completion
• Four other tags for using geographical maps, progress bar, media player, and message box.
The following table lists the basic tags and attributes that display the Ajax-based features. For information on
additional forms-specific features, see
