Cols object

Previous Next

This object contains a collection of columns.

When calling $.udb(), you can refer to columns with arrays or simple strings, using the selection techniques below:

 

 

collapseSelecting by column ID

A column ID is the combination of a '$' symbol and a number. Refer to it simply by using the column ID itself:

column-id
collapseSelecting by name

A column name is the name defined for the column in USoft Web Designer. If the column is in the current data source, refer to it simply by using the column name itself:

column-name

 

If the column is in an embedded data source, refer to it by naming the embedded data source, followed by a forward slash ('/'), followed by the column name:

embedded-data-source-name / column-name
collapseSelecting by column type

You can select a column by its type, using one of the meta selectors listed here. You cannot combine these meta selectors with other ways of selecting columns.
