Struts2 + Dojo 0.4 + unbeforeunload problem
Hi!!
If I have the following code in a jspx loaded via , when I go to
another page (also loaded via ) the "onbeforeunload" event is not
triggered. It is only triggered when the page is not loaded using ajax.
What can I do to make it works both when the page is downloaded at all
from server and when only a part is using ajax (using tag)?
http://www.w3.org/1999/xhtml";
xmlns:jsp="http://java.sun.com/JSP/Page";
xmlns:fmt="http://java.sun.com/jsp/jstl/fmt";
xmlns:c="http://java.sun.com/jsp/jstl/core";
xmlns:s="/struts-tags"
xmlns:scheduler="/scheduler-html.tld"
version="2.0">
onbeforeunload = function() {
if (formIsDirty(document.forms[1])) {
return confirm('Unsaved changes. Do you want to continue?');
}
}
...
Thanks.

If you assign a listener directly to onbeforeunload or onload you'll overwrite the listeners that dojo needs to assign (or vice-versa, dojo will overwrite yours). Check the dojo docs for examples. I can't think of it off the top of my head. Also, there should be a dojo-specific event you can subscribe to for the completion of an ajax request, rather than the page-related events. Check the recipes for that. Hope that helps a little. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Struts2 + Dojo 0.4 + unbeforeunload problem
Using dojo.addOnUnload(function) neither works. Besides that, I would need sht like dojo.addOnBeforeUnload, but it does not exist. I don´t think I should subscribe for an ajax-request-completion event, but for the beforeunload one, don´t I? Thanks. Jeromy Evans escribió: Pablo Vázquez Blázquez wrote: No idea or miss-explanation?

Re: Struts2 + Dojo 0.4 + unbeforeunload problem
Javascript within a remote div is not evaluated by default. Not sure
about s:div, but sx:div has executeScripts which must be set to true.

Re: Struts2 + Dojo 0.4 + unbeforeunload problem
I have executeScripts="true" in my tag.
Thanks.

dojo.connect does not exist in dojo 0.4 :( And separateScritpts attribute neither does in struts 2.0.9.

var form = document.forms[0]; if ((form) && (formIsDirty(form))) {var a = confirm("There are unsaved changes. Do you want to continue?");if (!a) { dojo.event.topic.publish("/cancelNavigation"); //HOW TO CANCEL NAVIGATION?? } }onbeforeunload = function(e) {if (formIsDirty(document.forms[0])) { e.returnValue = "There are unsaved changes."; } } When calling topic "/cancelNavigation" the event paremeter is undefined... Do you know any way to cancel navigation? I mean, cancel rendering the served page. Jeromy Evans escribió: Pablo Vázquez Blázquez wrote: Using dojo.addOnUnload(function) neither works.

Re: Struts2 + Dojo 0.4 + unbeforeunload problem
I don't really know as i don't use dojo or the ajax tags for any more for all the same reasons you're experiencing. Dojo's event model is based on AOP concepts; which allows you to bind functions to the event, before the event or after the event. So you need a listener attached to before the unload event and tell it to not proceed with the default operation...somehow... If this was native javascript you'd simply call event.preventDefault() Related example: ie. So, if you were doing a confirm for a submit, the submit button would publish a topic (/submit) You attach a listener to the before /submit topic It prompts "Are you sure?" If they say no, you cancel the event by setting the event.cancel flag. In the case of a beforeunload event caught via dojo...not sure. But if you can get the listener invoked by dojo, then either the scope (this) or the argument (event) will reference an event object that probably has the cancel flag. Otherwise you could try a e.preventDefault using plain old javascript if you have a reference to the native event object. The recipes below are for Dojo 0.4.x; so even though they use 2.1.x tags, the javascript itself also works in Struts 2.0.x; you just have to write the javascript yourself thats included by within the new tag widgets. http://struts.apache.org/2.x/docs/ajax-and-javascript-recipes.html Pablo Vázquez Blázquez wrote: var form = document.forms[0]; if ((form) && (formIsDirty(form))) {var a = confirm("There are unsaved changes.
