Knowls
This code fragment shows how to apply a javascript-enabled popup bit of knowledge (a knowl).
| PG problem file | Explanation |
|---|---|
$PAR
Here is a knowl
\{ knowlLink("click me", value=>'This is the inside of a knowl. If you click again, I will go away') \}
$PAR
$PAR
Here is another knowl
\{ knowlLink("click me", url=>'url_of_file_with_information') \}
$PAR
|
Instead of specifying a value, you can specify the url of a file with html in it, and that html will appear in the knowl. Then you can use one file in multiple places. |
return knowlLink($display_text, url=>$envir{'localHelpURL'}.$infoRef);
|
As another example, here is the last line of the definition of helpLink() where the knowl containing the help message is created after defining the variables which contain the url for the help file. |
