Subject [CForms] - No @id generation for <wd:output>
Date Sat, 14 Feb 2004 00:38:23 GMT
Hi:

I finally found a workaround to implement calculated widgets with
client-side JS (CSJS). To enhance the current support for CSJS I think we
need to define an id attribute for <wd:output>.

If we have an <wd:field> in the definition file:

<wd:field id="amount">
  <wd:label>Amount</wd:label>
  <wd:help>The Amount</wd:help>
  <wd:datatype base="decimal"/>
  <wd:validation><wd:range min="0"/></wd:validation>
</wd:field>

and in the template we wrote:

<wt:widget id="amount">
  <wi:styling size="10" onchange="calculateTotal(this);"/>
</wt:widget>

The generated HTML snipet is:

<input title="" value="100" id="amount" name="amount" size="10"
           OnChange="calculateTotal(this);">
  <span class="woody-field-required"> * </span>
  <div style="visibility:hidden; position:absolute;top:120px;right:0;"
        id="helpN10290" class="woody-help">Total de Costo</div>
  <script type="text/javascript">
      var helpWinN10290 = woody_createPopupWindow('helpN10290');
  </script>
  <a onclick="helpWinN10290.showPopup('N10290');return false;"
    href="#" id="N10290"><img src="images/help.gif" border="0"></a>

The id="amount" attribute is useful when we need to locate an object using
DOM in CSJS.

But, this attribute does not exist when we use a <wd:output> in
definition. :-(

I think we would generate at least a <span id="theOutputTagId"> for
<wd:output>. Tha way using CSJS we can easily find the <wd:output> we want
to change using CSJS.

WDYT?

Best Regards,

Antonio Gallardo
