Question

I am using a struts2 autocompleter tag. Now i want to invoke a javascript function when user selects some value in the drop down. I tried onChange, onSelect, onClick event but nothing works 🙁 Please tell me your suggestions on this.

You’d use Dojo “topics”.

When a selection is made the valueNotifyTopics are fired. See the autocompleter docs for details. There is an example there, shown below:

<script type="text/javascript">
dojo.event.topic.subscribe("/value", function(value, key, text, widget){
    alert('inside a topic event. after value changed');
    //value : selected value (like "Florida" in example above)
    //key: selected key (like "FL" in example above)
    //text: text typed into textbox
    //widget: widget that published the topic
});
</script>   

<sx:autocompleter valueNotifyTopics="/value" href="%{#ajaxTest}" />

Note that the Dojo tags have been deprecated since Struts 2.1 and will be archived in the next release.
