Ask a Jedi: Smaller Dumps

Ok, I swear this is the last childish entry title (for this week). A few days ago I blogged about how you can save the result of a cfdump for later use. It occurred to me that I bet many folks aren’t aware of the very useful attributes of the cfdump tag. Here is a quick run down:

  • Label: Did you know that you can provide a label to the dump? This is useful if you are running multiple dumps on one page. I almost always use a label even if I only have one dump.
  • Expand: By default the result of a cfdump will create a large block of data on your screen. You can use expand=false to automatically contract the data. Did you know that you can expand and collapse individual nodes of a dump just by clicking on their names?
  • Top: My absolute favorite attribute. Ever dumped a query and were dismayed by the 200+ rows that suddenly showed up in your browser? The top attribute lets you dump a query and restrict it to a certain number of rows. It also works on structs by preventing you from going too deep into a nested struct. In other words, for structs the top attribute references how deep the dump will go. </ul>
