t5.0.11 help in update my own components
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!!!

Thank u for ur warm answer,your suggestion give me some idea indeed.
but I want to code something special.
first, a select(A) is rendered for ready,when a onchange event is
activated,there will be another select(B) which is a children set of some
value in select(A) is rendered.......and it is in the same way when
select(B)'s onchange envent is trigerd .....select(C)...........
some structure in my table is:
id name pid ....
0 a1
0|1 b1 0
0|2 b2 0
0|1|3 c1 0|1
0|3 b3 0
0|2|1 c2 0|2
....................
I have no idea do I describe my problem in detail.....but I have tryed my
best.
thank u very much!!

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
