How to post javascript var to Struts Action inside topic method ?

[camusg]

Hello everybody,

With my GridTag, I want to select some lines and I want to post them
to my struts action.
I have seen "Get Selected Rows" button in showcase, but I don't know
how I can modify href in javascript...

Here is my test, starting with "grid-multi.jsp" of showcase :
<s:url id="urlEcho" action="echo"/>
<sj:submit id="grid_multi_testbutton" href="%{urlEcho}"
value="Test Guy" onBeforeTopics="testTopic" button="true"/>

I use the Echo Action, with echo attribut containing id list (from
selected lines of my grid)
I want to create an URL like this : echo.action?echo=11,121,456

And my javascript, in "showcase.js" :
$.subscribe('testTopic', function(event, data) {
var s;
s = $("#gridmultitable").jqGrid('getGridParam', 'selarrrow');
// TODO some code for adding var s to href
});

Is anyone has an idea ?

Thanks a lot !

Guillaume.

PS : I saw posts for custom buttons in grid... but I want an external
button for only specific grids, not for all.

I do not try it but I think this should work.

<form id="myform">
<input id="echo" type="hidden" name="echo" value="" />
</form>

<s:url id="urlEcho" action="echo"/>
<sj:submit
id="grid_multi_testbutton"

formIds="myform" href="%{urlEcho}"

value="Test Guy"
onBeforeTopics="testTopic"
button="true"/>

<script>

$.subscribe('testTopic', function(event, data) {

var values = $("#gridmultitable").jqGrid('getGridParam',
'selarrrow');
$('#echo').val( values )
});
</script>

Thanks for idea !

I tried your code, but I found a problem...
I found that sj:submit does not call onBeforeTopics method inside a
form or with a formIds reference.
When I change onBeforeTopics by onClickTopics, javascript method
called, but at same time as my http request...

Is there a bug here ?

Finally, i find one solution :

In jsp, I put sj:submit into s:form... but it is not mandatory :
<s:form id="myform" action="echo">
<s:hidden id="hiddenEcho" name="echo"/>
<sj:submit id="grid_multi_testbutton"
value="Test Guy"
onClickTopics="testTopic"
button="true"/>
</s:form>

In javascript, I define the testTopic method :

$.subscribe('testTopic', function(event, data) {
var values = $("#gridmultitable").jqGrid('getGridParam',
'selarrrow');

document.myform.echo.value = values;
document.myform.submit();
});

I tested with onBeforeTopics, but it don't work in this sample.
I tried "$('#hiddenEcho').val(values);" but it don't work...

With that code, i can post selected id to my struts action.

I think if <sj:submit> can support this natively it would be great. This is a common use.

As well as <sj:a>. It's a so comon use to append parameters dynamically in client side, but the tags seems not changable once generated.

If I miss anything, please do let me know.

A plain onClick event handler can do this well...
