execute javascript after action's html renders
On Struts 2.1.6, Dojo and JSON plugins.
I want to execute some JavaScript after an action's HTML finishes loading.
I can't figure out how to make this happen consistently. The action that
I'm trying to modify is as part of another action. When I access the child
action directly, the script runs. When I access it through the parent
action, it doesn't.
There is an attribute "executeScripts" (or similar) set, but... as near as
I can tell, the script doesn't get run for some reason.
So... what's the best way to ensure that a script gets run when it's loaded
by an action? Where might this script be stripped or otherwise disabled
from running?
Any help appreciated.

Thanks for the replies, Martin and Li.
So, I've tried both of these things (before resorting to the mailing list,
actually), but as I pointed out in my note, the inline <script> tag never
seems to get executed, despite my setting of the *executeScripts* attribute
in the containing action's <sx:div> tag.
Again, I have this containing action, call it *parent.action* with something
like this:
<sx:div href="child.action" executeScripts="true" />
And then in the child, this:
... html/jsp code...
<script>
alert("blah blah blah");
</script>
So, that script never gets run. Even when I put the dojo.addOnLoad() into
that script... the script never gets run.
Is there some bug in the executeScripts attribute? Is there some other
mechanism that might be stripping or otherwise preventing the script from
executing?
Thanks,
Colin

Construct your JSP page with a script for an OnLoad JS function e.g.
<script>
var index = -1;
var runningOgnl = true;
var ognlBase = "${ognlBase}";
var jspBase = "${jspBase}";
var ognlCount = 9;
var jspCount = 5;
dojo.addOnLoad(function() {
var classSrc = dojo.byId("classSrc");
dojo.io.updateNode(classSrc, "${viewClass}");
dojo.html.hide("previous");
dojo.html.hide("next");
});
dojo.event.topic.subscribe("/reloadGuide", function() {
next();
});
function startOgnl() {
selectOGNLTab();
index = -1;
runningOgnl = true;
change(1);
updateNavigation();
}
function startJSP() {
selectJSPTab();
index = -1;
runningOgnl = false;
change(1);
updateNavigation();
}
function execOgnl(id) {
var exp = dojo.string.trim(dojo.byId(id ? id : "example").innerHTML);
dojo.byId("wc-command").value = exp;
keyEvent({keyCode : 13}, '${jspEval}');
}
function execJSP(id) {
var exp = dojo.string.trim(dojo.byId(id ? id : "example").innerHTML);
dojo.byId("jsp").value = unscape(exp);
dojo.event.topic.publish("/evalJSP")
}
function unscape(str) {
return str.replace(/&/gm, "&").replace(/</gm, "<").replace(/>/gm, ">").replace(/"/gm, '"');
}
function selectClassSrcTab() {
dojo.widget.byId("mainTabContainer").selectTab("classTab");
}
function selectJSPTab() {
dojo.widget.byId("mainTabContainer").selectTab("jspTab");
}
function selectOGNLTab() {
dojo.widget.byId("mainTabContainer").selectTab("ognlTab");
}
function change(delta) {
index+=delta;
var url = (runningOgnl ? ognlBase : jspBase) + index + ".jsp";
var bind = dojo.widget.byId("guideBind");
bind.href = url;
dojo.event.topic.publish("/loadContent");
updateNavigation();
}
function updateNavigation() {
if(index <= 0) {
dojo.html.hide("previous");
} else {
dojo.html.show("previous");
}
var top = runningOgnl ? ognlCount : jspCount;
if(index == top - 1) {
dojo.html.hide("next");
} else {
dojo.html.show("next");
}
}
</script>

Do you mean calling one action, from another action page, using AJAX?
Let's say, ActionA is the container page, some AJAX code running in
this page, retrieving the response of ActionB, and append the response
to the container page.
Do I understand it right?
In this case, you can embed JavaScript code, in the page code of ActionB, likes:
===========================================
<html code start>
</html code end>
<script type="text/javascript">
do something here.
</script>
===========================================
or you can use the "success" event of AJAX.
See: http://api.jquery.com/jQuery.ajax/
for more information.

Re: execute javascript after action's html renders
Posted by Colin Freas <cf...@gmail.com>.
So, the "parent" action is using a Dojo *div* tag, with the
*executeScripts* attribute
set to true.
The script in the "child" action, which is referenced in the *div* tag, is
inline JavaScript.
So parent is like:
<sx:div href="child.action" executeScripts="true" />
Child is:
... html/jsp fragments ...
<script>
alert("blah blah blah");
</script>
If I go to child.action from a browser, script runs. If I got to
parent.action, script doesn't run.

How is the JavaScript implemented in the child action?
And do you mean that an <s:action.../> tag is being used (from a JSP? FM?)
to load an action (the "child" from above)?
