Answer Format Help Links
This PG code shows how to add answer format help links to problems.
| PG problem file | Explanation |
|---|---|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "AnswerFormatHelp.pl", "parserImplicitPlane.pl", ); TEXT(beginproblem()); |
Initialization:
We need to include the macros file |
Context("ImplicitPlane")->variables->are(x=>"Real",y=>"Real");
$answer = ImplicitPlane("x+y=2");
|
Setup:
By declaring there are only two variables, |
BEGIN_TEXT
Enter an equation for a line through the points
\( (0,2) \) and \( (2,0) \).
$BR
$BR
\{ ans_rule(20) \}
\{ AnswerFormatHelp("equations") \}
END_TEXT
|
Main Text:
We use
It is possible to change the link text to \{ AnswerFormatHelp("equations","help entering equations") \}
It is possible to provide a link to an external help file using |
$showPartialCorrectAnswers = 1; ANS( $answer->cmp() ); ENDDOCUMENT(); |
Answer Evaluation: |
Instead of using a link to an external file, use the following:
HEADER_TEXT(<<END_HEADER_TEXT);
<script type="text/javascript">
<!--
function openhelpCustom1() {
OpenWindow=window.open("","answer_format_help","width=550,height=550,status=0,toolbar=0,location=0,menubar=0,directories=0,resizeable=1,scrollbars=1");
OpenWindow.document.write("<title>Help With Something</title>")
OpenWindow.document.write("<body bgcolor='#ffffff'>")
OpenWindow.document.write("<center><h2>Help With Something</h2></center>")
OpenWindow.document.write("<ul>")
OpenWindow.document.write("<li><font color='#222255'>Header:</font><blockquote>Explanation <code>pi/3</code></blockquote></li>")
OpenWindow.document.write("<li><font color='#222255'>Header:</font><blockquote>Explanation <code>pi/3</code></blockquote></li>")
OpenWindow.document.write("</ul>")
OpenWindow.document.write("</body>")
OpenWindow.document.write("</html>")
OpenWindow.document.close()
self.name="main"
if (window.focus) {OpenWindow.focus()}
return false;
}
-->
</script>
END_HEADER_TEXT
BEGIN_TEXT
\{ htmlLink("#","help (something)","onClick='openhelpCustom1()';") \}
END_TEXT
