History | |
ColdFusion MX 6.1: Added the ability to dump COM objects; it displays the methods and Get and Put properties typeinfo information for the object. | |
Usage | |
The expand/contract display capability is useful when working with large structures, such as XML document objects, structures, and arrays. | |
To display a construct, use code such as the following, in which myDoc is a variable of type XmlDocument:
<cfif IsXmlDoc(mydoc) is "True"> <cfdump var="#mydoc#"> </cfif> |
|
The tag output is color-coded according to data type. | |
If a table cell is empty, this tag displays "[empty string]". | |
Example
This example shows how to use this tag to display a URL variable. URL variables contain parameters that are passed in a URL string in a page request. <cfdump var="#URL#"> |
