Nice. You can save yourself a little trouble with:
var title = jmolEvaluate('getProperty("fileHeader").split().find("TITLE")')
Also, realize that this goes back and retrieves the file again from its
source. If you know you want to use the file header this way, it's more
efficient to use
set pdbGetHeader TRUE
(uh, undocumented, I see...)
This setting instructs Jmol to preserve the file header in memory when the
file is loaded. It is used in Jmol Protein Explorer.
Since you are really wanting to display this in Jmol, you might consider
something like the following Jmol script, which requires no JavaScript:
function getHeader()
var titleLines = getProperty("fileHeader").split().find("TITLE").split()
for (var i = 1; i <= titleLines.size;i = i + 1)
titleLines[i] = (titleLines[i])[11][0].trim()
end for
return titleLines.join("|")
end function
set echo bottom left
echo @{getheader()}
Something like that....
