Question

in .gsp file i have javaScript function

<script type="text/javascript">
 function getCurrentItemNumber(){
        return document.getElementById('item_itemNumber').innerHTML.substr(6);
    }
</script>

and in g:remoteLink I like to pass param using that function

something like following …

<g:remoteLink id="remove_item_button" action="removeItem" update="itemBox"
            params="[itemNumber:getCurrentItemNumber()]">- Remove Item</g:remoteLink>

How can I achieve that?

Answer 1

AS workaround I can suggest following

1. change g:remoteLink to simple link

   “<“a id=”remove_item_button” class=”btn small primary” onclick=”removeItem();”>- Remove Item “<“/a>

2. Add javaScript function which will submit data via AJAX

   function removeItem() {
   $.ajax({type:’POST’,
   data:{‘itemNumber’:getCurrentItemNumber()},
   url:’${createLink(action: ‘removeItem’)}’,
   success:function (data, textStatus) {
   jQuery(‘#itemBox’).html(data);
   }});
   }
