Javascript: PG Code Snippet
This code snippet shows the essential PG code to include javascript in a WeBWorK question. Note that these are insertions, not a complete PG file. This code will have to be incorporated into the problem file on which you are working.
It might be nice to include a different example than this here.
| PG problem file | Explanation |
|---|---|
loadMacros("parserNumberWithUnits.pl");
|
We don't need any changes to the tagging and description or initialization sections of the WeBWorK PG file to include javascript. This particular example, however, involves an answer with units , so we have to include the parser module for that. |
## include javascript to open units
## help window
HEADER_TEXT(<<EOF);
<script language="javascript"
type="text/javascript">
<!-- //
function unitspopup() {
var url = "/webwork2_files/units.html";
var opt = "height=625,width=600,location=no," +
"menubar=no,status=no,resizable=yes," +
"scrollbars=yes,toolbar=no,";
window.open(url,'examdata_info',opt).focus();
}
// -->
</script>
EOF

In the problem set up section we can include any javascript that is to be inserted into the header of the web page that's created by using the |
BEGIN_TEXT
Enter 3 kg: \{ ans_rule(10) \}
$BR
(include
\{htmlLink("javascript:unitspopup()","units")\})
|
We can then use the function in the problem; here we include it as a link. |
ANS( NumberWithUnits("3 kg")->cmp() );
|
No changes are needed in the answer and solution section of the file, except any use of the javascript that one uses there. Here we don't have any changes. |
