Hi, I think what you're asking is how to attach application event handlers (on the server-side like void onChange()) like you would with other components. If I've misunderstood you, I'm sorry. You're first problem is how you create the select element. By manually writing a tag, you're not actually creating a T5 component, and therefore can't receive any events from it. For a proper component use select:
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry/corelib/components/Select.html Now if you are trying to attach server side handlers to a select's client-side onchange event, you'll need some ajax. tapestry5-components provides a mixin that handles this, which you can find here: http://87.193.218.134:8080/t5components/t5c-commons/ref/org/apache/tapestry/commons/mixins/OnChange.html sincerely, chris 孟凡振 wrote: > in my component a html <select> tag is rendered,and I want to add a onchange > envent to it. > below is some code ... > > select.attribute("onchange","alert(this.options[this.selectedIndex].value);" > ); > > select is a element created by /*writer.element("select")*/ > > trigering a javascript event is ok here .. > > but my problem is how to triger this component itself with onchange event. > updating itself in result > > any one in warm heart could help me? > thanks in advance!!! > -- http://thegodcode.net --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
