Hi,
you can use Ajax.Request of Prototype for it.
Create a Action Link for register the method and call this method by Ajax.
Example:
////////////////////////////////////////////////////////////Page
Class///////////////////////////////////////////////////////////////////////////////
@Property
private String url;
/**
* Register the action Link
*/
void preRender() {
Link link = recursosComponente.createActionLink("firstTextField",
false, new Object[0]);
url = link.toAbsoluteURI();
}
/*
* Action Link Event
*/
StreamResponse onFirsTextField() {
String value = request.getParameter("firstValue");
// do some thing
//return a stream response
}
///////////////////////////////////////////////////////TEMPLATE//////////////////////////////////////////////////
<input t:type="TextField" id="first" onBlur="callAjax()"/>
<input t:type="TextField" id="second"/>
<script>
function callAjax() {
var parameter = 'firstValue=' + $('first').value;
new Ajax.Request('${url}',parameters: parameter, {
onSuccess: function(transport) {
// transport has a Stream response returned
// do some thing
}
});
</script>
