There are many places you can hook in. If you only have list facets (as
opposed to numeric range facets, hierarchical facets), then look in
http://static.simile.mit.edu/exhibit/api-2.0/scripts/ui/facets/list-facet.js
and find
Exhibit.ListFacet.prototype._filter = function(value, label,
selectOnly) {
That's what you want to override.
<script>
var oldFilter = Exhibit.ListFacet.prototype._filter;
Exhibit.ListFacet.prototype._filter = function(value, label,
selectOnly) {
// do your logging here
oldFilter.call(this, value, label, selectOnly);
};
</script>
You can also hook into the code that generates the DOM for the facet
values in
http://static.simile.mit.edu/exhibit/api-2.0/scripts/util/facets.js
Search for
Exhibit.FacetUtilities.constructFacetItem
Exhibit.FacetUtilities.constructFlowingFacetItem
(the first is used for facets that scroll and the second for facets that
don't scroll). You can see those
SimileAjax.WindowManager.registerEvent
calls.
