Detect change of value of struts2 autocompleter tag using javascript or jquery
Question
I am working on Struts 2 application. In my application, I need to use Struts 2 autocompleter tag. For that I have used struts2-dojo-plugin-2.3.1.2.jar jar file. I need to fetch the value from autocompleter once the value changes. I tried using onchange event but it was not working. Here is my code:
<%@taglib uri="/struts-dojo-tags" prefix="sx"%>
<html>
<head>
<script type="text/javascript">
function abc() {
var a = dojo.widget.byId("country");
var value1 = a.getSelectedValue();
document.getElementById("myText").value = value1;
}
</script>
<sx:head />
</head>
<body>
<sx:autocompleter name="country"
id="country" onchange="abc();" list="cricketNations" />
</body>
</html>
How do I achieve this. Help me solve this issue.

The struts2-dojo-plugin is deprecated. You need to use struts2-jquery-plugin .
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>
<html>
<head>
<sj:head jqueryui="true"/>
</head>
<body>
<div id="myText" class="result ui-widget-content ui-corner-all"></div>
<sj:autocompleter name = "country"
id = "country"
onChangeTopics = "autocompleteChange"
list = "%{cricketNations}" />
<script>
$.subscribe('autocompleteChange', function(event, data) {
var ui = event.originalEvent.ui;
var message = ui.item.value;
if (ui.item.key) {
message = '( '+ ui.item.key +' ) '+message;
}
$('#myText').html('<b>'+message+'</b>');
});
</script>
</body>
</html>

You might not be able to use HTML attributes with dojo widgets, you need to use dojo topics to subscribe for an event:
<%@taglib uri="/struts-dojo-tags" prefix="sx"%>
<html>
<head>
<script type="text/javascript">
dojo.event.topic.subscribe("/countryName", function(value, key, text, widget){
alert('inside onchange');
document.getElementById("myText").value = value;
});
</script>
<sx:head />
</head>
<body>
<sx:autocompleter name="country" valueNotifyTopics="/countryName" list="cricketNations" />
</body>
</html>
When value is selected for sx:autocompleter , topics will be published. See autocompleter doc here .
