I am displaying a collection of "messages" in my Meteor app. When my template "messages" is rendered, I apply this jQuery plugin called "gridalicious", which basically displays the messages in a pinterest-like format.
All works well, but when I insert a new message, that new message is displayed twice. When I refresh the browser, the duplicate is gone.
I'm applying the plugin as follow
Template.messages.rendered = ->
$("#message_box").gridalicious
width:250
animate:false
selector:".message"
gutter:0
Basically, if I get rid of this plugin, things messages display correctly, without any duplicates.
I'm not sure what would be causing this problem.
yes, i have similar prob like this. for this plugin or same satuation, to avoid it duplicates your template instance you can try make a global variable to handle your message box status, add some condition to decide if this new message's id is already been inside your global status handler and already been rendered, then don't render it twice.
global scope
isAlreadyBeenReneredId = null
Template instance of messages
Template.messages.rendered = ->
if isAlreadyBeenReneredId isnt #data._id
isAlreadyBeenReneredId = #data._id
options =
width: 250
gutter: 0
$("#message_box").gridalicious options
not real code, but some idea you might want to try.
As far as I know, Meteor does not render everything again and again, but only the differences. So I think the problem is, that you call the jQuery plugin multiple times on the same element.
I don't know the plugin, but there seems to be an append method, maybe this could be useful?
Try this:
if (Meteor.isClient) {
Meteor.startup(function () {
$(document).ready(function (){
$("#message_box").gridalicious({
width:250,
animate:false,
selector:".message",
gutter:0
});
});
});
}
Sorry I didn't know how to write the equivalent in coffescript.

I've been attempting to implement a ASP.NET MVC custom validation method. Tutorials I've used such as codeproject explain that you add data-val-customname to the element. Then jQuery.validate.unobtrusive.js then uses the third segment of the attribute
data-val-<customname>
as the name of the rule, as shown below.
$.validator.addMethod('customname', function(value, element, param) {
//... return true or false
});
However I just can't get the customname method to fire. By playing around I have been able to get the below code to work, but according to all the sources I've read Unobtrusive validation should not work like this.
$.validator.addMethod('data-val-customname', function(value, element, param) {
//... return true or false
});
I've posted an example of both methods
jsfiddle example
Any help would be much appreciated
I've updated my question hopefully to make clearer.
I have finally found got there in the end, but still feels like too much hard work and therefore I've probably got something wrong. Initial I was scuppered by a bug in Chrome Canary 62 which refused to allow the adding of a custom method.
My next issue was having to load jQuery, jQuery.validate and jQuery.validate.unobtrusive in the markup and then isolate javascript implementation in a ES6 class. I didn't want to add my adaptors before $().ready() because of my class structure and loading of the app file independent of jQuery. So I had to force $.validator.unobtrusive.parse(document);.
Despite this I was still having issues and finally debugged the source code and found that an existing validator information that is attached to the form was not merging with the updated parsed rules, and essentially ignoring any new adaptors added.
My final work around and admit feels like I've done too much, was to destroy the initial validation information before my forced re-parse.
Here is the working jsfiddle demo
Here is some simplified code
onJQueryReady() {
let formValidator = $.data(document.querySelector('form'), "validator" );
formValidator.destroy();
$.validator.unobtrusive.adapters.add("telephone", [], function (options) {
options.rules['telephone'] = {};
options.messages['telephone'] = options.message;
});
$.validator.unobtrusive.parse(document);
$.validator.addMethod("telephone", this.handleValidateTelephoneNumber);
}
I am learning about writing custom JavaScript for my Odoo 10 addons.
I've written the following piece of code:
odoo.define('ioio.io', function(require) {
'use strict'
const e = $('div.o_sub_menu_footer')
console.log('--testing--'.repeat(7))
console.log(e)
// the "Powered by Odoo" down the secondary menu
e.remove()
})
The code is well loaded and I can see my testing string in the console.
However when this code is being loaded before the target div, so e empty/not yet filled and thus its content is not removed.
Doing it manually from the console works.
My question is what is the right way to do that? And how to know exactly when the code gets executed?
You can
put your html code before the script tag in your file
use jQuery $(document).ready(...);
Place your script at the bottom of the <body> tag to make sure the DOM renders before trying to manipulate it.
This is an Odoo specific question, so you should use the Odoo standard way, which is via its base JS class. That class contains a ready() method which does exactly what you need.
In your case, to use that function, you need to require the class first. Then you can use ready().
Updating your code, it should look like this:
odoo.define('ioio.io', function(require) {
'use strict'
// require base class
var base = require('web_editor.base');
//use its ready method
base.ready().done(function () {
// put all the code you want to get loaded
// once the DOM is loaded within this block
const e = $('div.o_sub_menu_footer')
console.log('--testing--'.repeat(7))
console.log(e)
// the "Powered by Odoo" down the secondary menu
e.remove()
});
})
While your accepted answer leads to the same outcome, you might want to update it to this one since this is the Odoo way. It's generally advised to work within the Odoo framework as much as possible and customise only if really needed. (Though it can be tough to learn what features Odoo already provides because of its poor documentation.)
I need to run some client-side javascript from a button in a form view in Odoo 8. This button runs a python method which returns this dictionary:
{"type": "ir.actions.client",
"tag": "my_module.do_something",}
do_something is defined in a .js file as follows:
openerp.my_module = function (instance) {
instance.web.client_actions.add("my_module.do_something", "instance.my_module.Action");
instance.my_module.Action = instance.web.Widget.extend({
init: function() {
// Do a lot of nice things here
}
});
};
Now, the javascript is loaded and executed properly, but even before launching the init function, Odoo loads a brand new, blank view, and once the javascript is over I can't get browse any other menu entry. In fact, wherever I click I get this error:
Uncaught TypeError: Cannot read property 'callbackList' of undefined
What I need instead is to run the javascript from the form view where the button belongs, without loading a new view, so both getting the javascript stuff done and leaving all callbacks and the whole environment in a good state. My gut feeling is that I shouldn't override the init funcion (or maybe the whole thing is broken, I'm quite new to Odoo client-side js) , but I couldn't find docs neither a good example to call js the way I want. Any idea to get that?
Sorry, I don't work on v8 since a lot of time and I don't remember how to add that, but this might help you: https://github.com/odoo/odoo/blob/8.0/doc/howtos/web.rst
Plus, if you search into v8 code base you can find some occurence of client actions in web module docs https://github.com/odoo/odoo/search?utf8=%E2%9C%93&q=instance.web.client_actions.add
Thanks to the pointers simahawk posted in another answer, I have been able to fix my js, which is now doing exactly what I needed. For your reference, the code is as follows:
openerp.my_module = function (instance) {
instance.web.client_actions.add("my_module.do_something", "instance.my_module.action");
instance.my_module.action = function (parent, action) {
// Do a lot of nice things here
}
};
This is really tricky to get my head around as I'm not used to this style of programming/data management.
All I'm trying to do at the moment is pass a json object returned via breeze into a dynatree or fancytree.
The examples that exist online all assume that the tree will do the ajax call via "initajax" or that some weirdly convoluted custom binding handler is needed into which various objects are passed:
ko.bindingHandlers.dynatree = {
update: function (element, valueAccessor, allBindingsAccessor, viewModel) {
setTimeout(function () {
$(element).dynatree({
noLink: true, // noLink is required to 'unlock' the checkboxes
minExpandLevel: 2
})
// the timeout value shows the correct knockout bindings BEFORE dynatree kicks in.
}, 1000);
}
}
This all seems too complicated to me, surely? I already have the json object, I know that's working. If I use knockout to "foreach" bind it to some plain html then all data is displayed just fine. In my mind all I need to do is initialize the tree div and pass it the json object... It's just that I have no idea how to do that!
I've tried using the jsfiddle here: http://jsfiddle.net/Ebram/UhA3m/5/ but chrome developer tools complain about the element having no "dynatree" method when the custom binding handler fires. It's passing in a "ul" element and that could be the problem - surely it should be passing in the tree div, not the ul element?
Anyhow, if anyone could point me in the right direction I'd hugely appreciate it. As I'm using John Papa's SPA methodology, I'm also unsure as to where I would put any separate js initialization code as the underlying viewmodel isn't the right place for me to be doing a $(#tree).dynatree initialization type call, is it? I must admit I've not got my head around this yet.
I suppose all I'm looking for is something along the lines of "once the viewmodel for this view has finished loading and the knockout binding is being done, initialize the dynatree div and pass this json object to the tree" if that makes sense in pseudocode?
I can hopefully point you in the approximate right direction.
It seems dynatree can also take JSON from a file as well as an AJAX request. In this example Lazy Loading, if you look in the source code, there's:
// In real life we would call a URL on the server like this:
...
// .. but here we use a local file instead:
Storing your data in a file to get it in seems awfully wasteful. Now that we know it's a little flexible in what it gets, let's see where it uses the data and maybe we can get it to use a local variable instead. let see where it loads it
Looking in the dynatree source, there's a function associated with appendAjax. (line 1774 in my source.) A little short on time at the moment, but I'd find where it gets the JSON and what it does with it. Perhaps you can do the same thing outside or mod the handling of ajaxOptions to take a variable with the JSON.
I'm struggling with this even after reading the MSDN documentation and the following online guides:

I think my problem is easy to fix and that I just am thinking about something in the wrong way. Basically I am querying my web service and on success running the following method. I am then trying to bind the result to my listview. For now I am using a hardcoded value publicMembers.itemlistwhich has been declared at the top of the document just to make sure I can actually bind to the list before doing it with my query results. Ignore line 2 for now.
Success Method:
_lookUpSuccess: function xhrSucceed(Result) {
var response = JSON.parse(Result.responseText);
listView = document.querySelector("#termTest");
ui.setOptions(listView, {
itemDataSource: publicMembers.itemList,
itemTemplate: document.querySelector(".itemtemplate"),
})
},
Now, instead of using document.querySelector, I have also tried with WinJS.Utilities.id and WinJS.Utilities.query, neither of which worked either. This doesn't break my code and introduce an error but it doesn't bind to the listview either so I think I have an issue in querying the right DOM element. However exactly the same code does work if I add it to the top of the script, it is only when I place it in this method that it stops working.
EDIT: Also to clarify, when I debug publicMembers.itemList is storing the values I expect them to be.
Please point out if I have explained things poorly and I will try and improve my question.
Thanks.
I haven't used WinJS.UI.setOptions, but rather this other way of setting the data source. Can you see if it works?
_lookUpSuccess: function xhrSucceed(result) {
var response = JSON.parse(result.responseText);
listView = document.querySelector("#termTest");
listView.winControl.itemDataSource = publicMembers.itemList;
},
This would assume you're defining the itemTemplate as part of the data-win-options attribute of your ListView's HTML element. You could also probably just do listView.winControl.itemTemplate = document.querySelector(".itemtemplate") if you prefer to set it programmatically.
