A Tinderbox Reference File : Export Codes : Export Code Scope : Item-based : ^exists( item | attribute)^

^exists( item | attribute)^

Code Type:	Boolean Comparison
Code Scope of Action:	item

^exists( object )^

If the item exists for current note, this condition inside a in ^if(condition)^ block statement is true, where object is parent, child, childLinks, basicLinks, inboundLinks, lastChild, next, previous, nextSibling, and prevSibling.

^exists( attribute )^

This condition is true if the attribute (represented here by attribute) exists for the note, and if it is:

not zero, if the attribute is a number
not empty, if the attribute is a string
not black, if the attribute is a color

... and it is always true if the attribute is a date.

But ^if(^exists(text))^ cannot be used to check if the note has some text content as text is not an attribute. Use ^if(text(this))^ instead.

Up: Item-based
Previous: ^equal( data1, data2 )^	Next: ^file( item )^
