| Anchor | | public class Anchor extends RemoteCallUIBean (Code) | |
A tag that creates a HTML <a href='' /> that when clicked calls a URL remote XMLHttpRequest call via the dojo
framework. The result from the URL is executed as JavaScript. If a "listenTopics" is supplied, it will publish a
'click' message to that topic when the result is returned.
Examples
<ww:a id="link1" theme="ajax" href="/DoIt.action" errorText="An error ocurred" showErrorTransportText="true">
<img border="none" src="<%=request.getContextPath()%>/images/delete.gif"/>
<ww:param name="id" value="1"/>
</ww:a>
Results in
<a dojoType="BindAnchor" evalResult="true" id="link1" href="/DoIt.action?id=1" errorHtml="An error ocurred"
showTransportError="true"></a>
Here is an example that uses the postInvokeJS. This example is in altSyntax=true:
<ww:a id="test" theme="ajax" href="/simpeResult.action" preInvokeJS="confirm(\'You sure\')">
A
</ww:a>
