Folks, It seems easy to test for the existence of a field with the has operator, and even if it exists at all !has:field<fieldname>
- I have buttons to add something to a json data tiddler and give it a value Yes - I can reverse this with a button give it a value No Can any one tell me how I can detect the index is not present at all? Eg !has:index[indexname] Thanks in advance Regards Tony -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
