Here is a snippet from my template: ...... <td><input type="checkbox" name="c_row" tal:attributes="value row/id"></td> ...... <a href="" onclick="document.forms[0].c_row.checked = true; for(i=0; i<document.forms[0].c_row.length; i++) { document.forms[0].c_row[i].checked = true; } return false">Select all</a> <a href="" onclick="document.forms[0].c_row.checked = !document.forms[0].c_row.checked; for(i=0; i<document.forms[0].c_row.length; i++) { document.forms[0].c_row[i].checked = !document.forms[0].c_row[i].checked; } return false">Invert selection</a><br> ....... This works well but I need c_row to be passed as a list of integers. In this form it is passed as a string or list of strings. A good replacement I tought to be the follow one: ...... <td><input type="checkbox" name="c_row:list:int" tal:attributes="value row/id"></td> ...... but in this case I dont now how to handle javascript. Any help would be appreciated! TNX. --------------------------------------------------------------------------- This message (including any attachments) is confidential and may be privileged.
