Howto hook into 'PageLoaded' observer in SilverStripe 3? - silverstripe

I need to execute a jQuery function after a page loaded. The docs told me that it would be possible to hook into the 'PageLoaded' observer.
So I tried it like shown there. I put this function
Behaviour.register({
'#Form_ItemEditForm' : {
initialize : function() {
this.observeMethod('PageLoaded', this.pageLoaded);
this.observeMethod('BeforeSave', this.beforeSave);
this.pageLoaded(); // call pageload initially too.
},
pageLoaded : function() {
alert("You loaded a page");
},
beforeSave: function() {
alert("You clicked save");
}
}
});
into my cms.js which get's loaded in the backend. I tried it inside and outside (function($) { .. code ..}(jQuery)); and also inside the doucment.ready function inside the first function.
I always receive the same error in my console Uncaught ReferenceError: Behaviour is not defined.
Where is my mystake?

I believe you may have been looking at docs for 2.4, not 3.x
Version 3 and up are built using jQuery.entwine, where this from memory is old Prototype plugin stuff from 2.4, meaning of course that Behaviour is not defined, just as the error says.
The docs have recently been updated, so perhaps visit again, you might learn something new & much more helpful :)

How to get patterns widgets to work in an iframe overlay

I have some "classic" tiles on a Plone 4.3.6 site, which contain a richtext field and two RelationChoice fields using plone.formwidget.contenttree widgets.
I have installed plone.app.widgets 1.8.0 (along with p.a.contenttypes), and I can't get the new TinyMCE and the new relateditems pattern widget to work properly. If I load the tile view URL directly (at the ##edit-tile/.... URL), the widgets actually show up and work properly. But in the iframe/overlay, they don't.
The prep-overlay looks like this:
jQuery('.tile-editable').each(function () {
jQuery(this).find('a.tile-edit-link, a.tile-delete-link').
prepOverlay({
subtype: 'iframe',
config: {
onLoad: function (e) {
jQuery('body').addClass('noscroll');
return true;
},
onClose: function() {
jQuery('body').removeClass('noscroll');
location.reload();
}
}
});
});
The iframe loads ++resource++plone.app.widgets.js in the header, and the fields are given the pat-relateditems and pat-tinymce classes as expected. But the init method inside the relateditems pattern is never called. I suppose the iframe DOM is not parsed for patterns, but I don't know where to look for the cause of this.
FWIW, there is an error in the console:
Uncaught Error: Mismatched anonymous define() module: function (){return eb}
http://requirejs.org/docs/errors.html#mismatch
in plone.app.widgets.js:166, but I don't know where that's coming from, or if it matters.
Are there any tricks to getting mockup widgets to work in an ifram overlay?
To reinitialise all patterns you can do:
var registry = require("pat-registry");
registry.scan(SELECTOR); // document or iframe or wherever you want to rescan all patterns.
IMHO you could do this on the onLoad method.

Framework7 starter page "pageInit" NOT WORKING

anyone using framework7 to create mobile website? I found it was great and tried to learn it by myself, now I meet this problem, after I create my App, I want to do something on the starter page initialization, here, my starter page is index.html, and I set data-page="index", now I write this below:
$$(document).on('pageInit', function (e) {
var page = e.detail.page;
// in my browser console, no "index page" logged
if (page.name === 'index') {
console.log("index page");
});
// but I changed to any other page other than index, it works
// my browser logged "another page"
if(page.name === 'login') {
console.log('another page');
}
});
Anyone can help? Thank you so much.
I have also encountered with the same problem before.
PageInit event doesn't work for initial page, only for pages that you navigate to, it will only work for index page if you navigate to some other page and then go back to index page.
So I see two options here:
Just not use pageInit event for index page - make its initialization just once (just make sure you put this javascript after all its html is ready, or e.g. use jquery's on document ready event)
Leave index page empty initially and load it dynamically via Framework7's mainView.loadContent method, then pageInit event would work for it (that was a good option for me as I had different index page each time, and I already loaded all other pages dynamically from underscore templates)
I am facing same issue and tried all solutions in various forums.. nothing actually worked. But after lot of RnD i stumbled upon following solution ...
var $$ = Dom7;
$$(document).on('page:init', function (e) {
if(e.detail.page.name === "index"){
//do whatever.. remember "page" is now e.detail.page..
$$(e.detail.page.container).find('#latest').html("my html here..");
}
});
var me = new Framework7({material: true});
var mainview = me.addView('.view-main', {});
.... and whatever else JS here..
this works perfectly..
surprisingly you can use "me" before initializing it..
for using for first page u better use document ready event. and for reloading page event you better use Reinit event.
if jquery has used.
$(document).on('ready', function (e) {
// ... mainView.activePage.name = "index"
});
$(document).on('pageReinit', function (e) {
//... this event occur on reloading anypage.
});

Trying to catch hideDropdown event in TextExt.js

I am using TextExtJs for an autocomplete feature where you start typing and the dropdown of suggestions appears below the text input and you can select a suggested option with arrow keys or mouse.
Everything is working great except that I am trying to perform a function after the user selects one of the suggestions. There is a hideDropdown event which I think is the proper event to use for this. Unfortunately I'm not understanding how to do this, this is what I have tried:
$('#usearch').textext({
plugins : 'autocomplete ajax',
ajax : {
url : 'usersuggest.php',
dataType : 'json',
cacheResults : true
},
autocomplete : {
onHideDropdown : function(){
alert('A happened');
},
hideDropdown : function(){
alert('B happened');
}
},
onHideDropdown : function(){
alert('C happened');
},
hideDropdown : function(){
alert('D happened');
}
});
None of these functions with the alert actually ever run. They do not interfere with the suggestion piece of it. How do I attach a callback to this event?
I'm facing the same problem here....
Unfortunately there is no proper solution. The manual is as rudimental as the examples provided on the plugin page.
I managed to bind a kind of "onAddingTag" event, refer to this: http://textextjs.com/manual/plugins/tags.html#istagallowed
$('#textarea').textext().bind('isTagAllowed', function(e, data) {
var valueAdded = data.tag;
data.result = true; //needs to be done, since we're abusing this event
};
Despite the fact that this may help with this issue, your next problem would be: when does the user remove a tag?
Finally I ended up, using another autocomplete library.

Durandal: How to route away from current view within that view's activate() function?

I have the following:
function activate(routeData) {
// make dataservice call, evaluate results here. If condition is met, reroute:
if (true){
router.navigateTo("#/someRoute");
}
alert ("should not be shown");
}
The alert is getting hit however, and then the view changes.
How do I fully navigate away from the current item and prevent any further code in that vm from being hit?
Update:
I tried using guardroute but I have to activate the viewModel to call the dataservice that returns the data that determines whether or not I should re-route. Using guardroute totally prevents the dataservice from getting called (since nothing in the activate function will get hit).
I also tried returning from the if block but this still loads the view / viewAttached / etc so the UX is glitchy.
The following worked for me in Durandal 2.0:
canActivate: function() {
if(condition)
return {redirect: 'otherRoute'};
return true;
}
activate: // Do your stuff
It's mentioned in the documentation: http://durandaljs.com/documentation/Using-The-Router.html
Here's #EisenbergEffect answer to a quite similar discussion in google groups.
Implement canActivate on your view model. Return a promise of false,
then chain with a redirect.
You might want to give #JosepfGabriel's example (discussion) a try in Durandal 1.2. Check the correct router syntax for your Durandal version, you might have to substitute it with something like router.navigateTo("#/YourHash", 'replace').
canActivate: function () {
return system.defer(function (dfd) {
//if step 2 has a problem
dfd.resolve(false);
})
.promise()
.then(function () { router.navigate("wizard/step1", { trigger: true, replace: true }); });
}
However this is NOT working in Durandal 2.0 and there's a feature request https://github.com/BlueSpire/Durandal/issues/203 for it.
You can't call redirect into the active method.
You can override the guardRoute method from router, to implement redirections.
You can do somehting like that:
router.guardRoute= function(routeInfo, params, instance){
if(someConditios){
return '#/someRoute'
}
}
You can return a promise, true, false, the route to redirect... You can find more information about that in the next link: http://durandaljs.com/documentation/Router/
Rainer's answer was pretty good and works for me adding this small fix.
Inside the then() block simply call the navigation like this
setTimeout(function() { router.navigateTo('#/YOUR DESTINATION'); }, 200);
that should fix your problem. The setTimeout does the trick. Without it the newly navigated page catches the old NavigationCancel from the previous one.
Adding a return in your if (true) block should fix this.
function activate(routeData) {
if (true){
router.navigateTo("#/someRoute");
return;
}
alert ("should not be shown");
}

How to debug template in Meteor/handlebars?

According to this blog post, I should register a helper to better debug handlebars templates, but is not working:
ReferenceError: Handlebars is not defined
So, how can I {{debug}} in Meteor/handlebars?
This is the helper function I use for debugging in my own projects:
Template.registerHelper("debug", function(optionalValue) {
console.log("Current Context");
console.log("====================");
console.log(this);
if (optionalValue) {
console.log("Value");
console.log("====================");
console.log(optionalValue);
}
});
You can then call it in your templates with {{debug}} and it displays the context you are currently in. Read more at http://docs.meteor.com/#/full/template_registerhelper.
In Meteor 0.4.0 you register handlers like this:
Template.myTemplate.helpers({
helper: function () {
// some code here
console.log(arguments);
}
});
There is no need to call Handlebars directly.
Make sure that you register your helper in client (or shared) meteor code.
Handlebars.registerHelper('helper', function() {
// Do stuff
});
This should be callable via {{helper}} in your templates.
For the sake of completeness: you can also use
Template.registerHelper('helper', helperFunc);
instead of Handlebars.regsterHelper('h',f);
A small reason this is better is that then your app won't need that much refactoring if you decide somewhere down the road that you want to use something else instead of Handlebars(i.e. Spacebars, the real name of meteors adaption) like jade for meteor.
This is really a comment to the accepted answer. Looking forward to one day hit 50 rep.
