Using WDDX

The following sections describe how you can use WDDX in ColdFusion applications. The first two sections describe the tools that ColdFusion provides for creating and converting WDDX. The remaining sections show how you use these tools for common application uses.

• Using the cfwddx tag
• Validating WDDX data
• Using JavaScript objects
• Converting CFML data to a JavaScript object
• Transferring data from the browser to the server
• Storing complex data in a string

Using the cfwddx tag

The cfwddx tag can do the following conversions:

A typical cfwddx tag used to convert a CFML query object to WDDX looks like the following:

<cfwddx action="cfml2wddx" input="#MyQueryObject#" output="WddxTextVariable">

In this example, MyQueryObject is the name of the query object variable, and WddxTextVariable is the name of the variable in which to store the resulting WDDX XML. Note

For more information on the cfwddx tag, see CFML Reference.
