> Right now you are restricting yourself into only gettingwhat you need and substitute its absence. But soon you will be ableto think backwards :) [code retroactively]; "I will create a Title for this content only if a given content structure implies one. Therefore, if the title is declared, I will create a title element,if not, the kind of this content doesn't need a title, but if the title is undefined\empty\left blank or so, I will substitute it withsay "Untitled"; etc., etc."
I think you are confusing the specifics of my example with my question. I had no intention of creating a title tag in HTML.
For clarity I am interested in a function that will generally check for the existence of an object.
I have done some googling around and am not able to find any type of generalized solution.
I may be stuck with the long drawn out object detection like a a.b a.b.c etc
I suppose I could send a string to a function then split the string on the . and then iterate through it to check for existence...
pseudo code...
exist('a.b.c.d.e.f')
function exist(text)
if typeof === string
t=split(text,'.')
iterate through t checking for existence break when not defined
else
return 'bad syntax'
/if
return true or false
/function
