Grails g:each 标签的问题

Question

I'm struggling to get ag:each tag to work. What I'm passing to the view is a list of hashmaps (something like this [ [: ], [: ] ] ). Each hashmap is of the form [location: somelocation, artist: someartist]. The code is the following:

CONTROLLER in the controller I'm passing the following:

[searchedResults : results.searchedResults]

VIEW

<g:each status="i" in="${searchedResults}" var="results">
   if(results.location!=null){
       var point${results.location.id} = new google.maps.LatLng(${results.location.lat}, ${results.location.lng});
       var myMarkerOptions${results.location.id} = {
                          position: point${results.location.id}, 
                          map: map
                         };
       var marker${results.location.id} = new google.maps.Marker(myMarkerOptions${results.location.id});   
   }    
</g:each>

Any ideas why this wouldn't work? Thanks!

GrailsGuy is right in that you can't write groovy code in the body of an each tag like that. But let me try and convert it to something for you, since it looks like your doing some javascript in there as well...I think all you need to fix is your if statement

<g:each status="i" in="${searchedResults}" var="results">
  <g:if test="${results.location}">
    //everything else seems like it would work, assuming your javascript
    // code is accurate
  </g:if>
</g:each>
