Wicket Ajax Event on Component with Parameters
Hi Folks,
i want to add an "custom" Event "filter" to an HTML-Component. So that
another plugin/function or something else, on client-side could call this
event and transfer some parameters (by ajax-post) to wicket on server-side.
Any Ideas for this?
I Tried with
gridView.add(new
WiQueryAjaxEventBehavior(FilterEvent.FILTER) {
@Override
protected void onEvent(AjaxRequestTarget target) {
Request request = RequestCycle.get().getRequest();
String[] params = request.getParameters("ids");
//params is every time empty
}
});
this generates a
$('#grid__view5').bind('filter', function() {
48 var
wcall=wicketAjaxGet('?wicket:interface=:1:table_watchlist:grid_view::IBehaviorListener:2:',null,null,
function() {return true}.bind(this));
49});
in my markup.
And it works, except for not transfering any parameters if i call
"$(#componentId).trigger("filter")"
Thanks in Advance for Help!

Instead of wicketAjaxGet() use wicketAjaxPost().
See how to pass the parameters in wicket-ajax.js

Hi Jeremy,
Thanks for your reply. It looks like what i've looking for. But i need this
with POST not with GET. Cause the GET-URL is to limited to internet
standards and i have to transfer a bunch of more data back to the
server-side.
Any hint for POST?
Thanks

instead of using wiquery event behavior, use your own and generate the
binding yourself:
new AbstractDefaultAjaxBehavior() {
CharSequence getCallbackScript(boolean onlyTargetActivePage) {
return "$('#" + getComponent().getMarkupId() + "').bind('filter',
function() { " +
"wicketAjaxGet('" + getCallbackUrl(onlyTargetActivePage) + "&myIDs=' +
getSelectedIDs() + );}";
}
}
notice that the getSelectedIDs() is a JS function that you would need to
define.... Fix the syntax (I probably have typos) and apply it to your use
case.

Sure i could.
But there are more and more complex Parameters as they could be added to an
URL ... so i need to Ajax-POST them, instead of GET .. this is my Problem.

Hi Martin,
Can you just read the options "[1,12,355]" on the body of the function
you defined and append them to the URL?

No the Grid Component doesnt know this.... or want to know this on
client-side.
Is it not possible just to implement a method, which could be called by :
$("#gridview").trigger("filter", { 'ids': [1,12,355]});
totally from outside?

Then the grid component should know what to send to the server side;-)
That's completely similar to the example I showed with AJAX slider
(slider sends positions to server side). Your grid will have to
iterate over the rows "state" (on client side) put that information
into a parameter and send it to the server side (and on the server
side do whatever you deem necessary with that information).
Best,
Ernesto

And how could i do this?
I dont want to reload the grid or anything. I just want to KNOW whats
"happen" on client-side... in some scenarios...
in My Example:
the user filters the grid totally client-side. But the Filter-Plugin should
tell my gridview-Component WHICH lines are still visible (ID-List)...
Any hints?
Thanks!

Hi,
Why not use Wicket standard AJAX submit machinery instead? And have
the grid rebuild itself after AJAX submit?

Okay, i'll try to explain what i want/have to do, with my noob-english ;)
I've written my own gridview component for a big web-application.
And some-one else who is responsible for the client-side thing, want to tell
my gridview "hey yo, filter this values i submit to you!".
So i thought, implementing a "Event" which could be called by anonther would
be the best id.
He want to deliver a json-array to my server-side implementation... how
should i offer this interface?
Thanks!

Doesn't your component knows what to transfer? I really do not
understand what you want to try to achieve... I have used a similar
approach to transfer client side state to the server side e.g.
new StringBuffer()
.append("var values = $(this).slider('values');")
.append("var url = '").append(slider.sliderContext.getCallbackUrl(true))
.append("&").append(SLIDER_EVENT).append("=").append(event.name())
.append("&").append(SLIDER_VALUE).append("=").append("'+").append(Slider.UI_VALUE)
.append("+'&").append(SLIDER_VALUES).append("=").append("'+").append("values")
.append(";")
.append("wicketAjaxGet(url, null,null, function() {return
true;})").toString());
For an AJAX slider to handle slider events on the server side.
> strictly speaking i want do transfer a json Object to server-side through

Build the JSON object using some client logic? E.g. if you want to
submit a form iterate over fields and compose a JSON out of it. Again
I can't see what you want to achieve.

How should i do this from a client-side call? I dont know with Parameter will
be submited from there.
strictly speaking i want do transfer a json Object to server-side through
the Event Call.

append the parameter to the URL? Just try url+"&ids=test" and see if you get it.
