how to trigger one widget event from another

[Johnson <jo...@soho.club.tw>]

Hi!

I define a repeater widget with an event in it
 
     <fd:repeater id="daily1List">
       <fd:field id="amt">
         <fd:label><i18n:text key="amt">amt:</i18n:text></fd:label>
         <fd:datatype base="decimal"/>
       </fd:field>
     </fd:repeater>
 
 <fd:repeater-action id="removeDaily1" action-command="delete-rows"
 repeater="daily1List" select="select">
           <fd:label><i18n:text
 key="removeDaily1">removeDaily1:</i18n:text></fd:label>
          <fd:on-activate>
          <javascript>
           var dList =  event.source.parent.lookupWidget("daily1List");
           var testv = new Packages.java.math.BigDecimal("0");
 
           for (var i = 0; i &lt; dList.size; i++) {
                 var row = dList.getRow(i);
                 num1 = row.lookupWidget("amt").value;
                testv = testv.add(num1);
         }
 
         var test = event.source.parent.lookupWidget("test");
         test.setValue(testv);
        </javascript>
       </fd:on-activate>
 
     </fd:repeater-action>
 
 I want to define a on-value-changed event in amt widget,like
<fd:on-value-change>
          <javascript>
              some code to trigger repeater-action "removeDaily1"
          </javascript>
</fd:on-value-change>

when the amt is changed , it trigger the event in removeDaily,how to?
 
 Best Regards
 
Johnson
