Creating view elements in VM using aurelia - aurelia

Is what I am trying to do in this gist possible?
https://gist.run/?id=bea803b05ad8d5b5e3e0afd59bb8dbb1
In app.html, I'm trying to use a repeat.for to create a custom element called button-row
In app.js, I'm creating two button row instances which I then place into a button row array so that I can use the repeat.for to iterate over it and create the button rows on the app.html view.
In button-row.html, I have a repeat.for to create the buttons using the btns array and setting the name of the button.
In button-row.js, I have two properties. label is the label for the button row and btns is the array of all the button names I want to create.
Sorry if this is a noob question, I have only been working with web development and aurelia for about a month.

Instantiating the ButtonRow objects yourself won't work. Aurelia instantiates the instances. you'll need to use the binding system to pass in the information to the custom element. I updated your gist here: https://gist.run/?id=6ec71143f566571960b7a182d4d98ed4
Also, you should refrain from abbreviating words like "Button" let your tooling save you the keystrokes, while making your code more readable :-)

Vuejs directive masonry detect prepend to array and redraw properly

I am using the vue-masonry plugin which let me create a masonry grid easily.
I created a system of infinite loading where you scroll to the bottom of the page and it append new pictures to an array binded with the vue-masonry plugin.
The problem happen when I created a system of polling for the new pictures that were upoaded by other users. Those new pictures need to be at the top of the masonry grid.
The plugin use two Vue Directive masonry (parent) and masonryTile (element). masonryTile has a v-for which loop through the array binded with my Vue instance (which does all the heavy lifting, preloading, sanityzing, etc...).
Is there a way in the directives to know the differences between something being appended or prepended? And try to react differently (I know masonry has some append/prepend method) but in here and with this plugin, the items where already added (at the beginning so the prepend works with Vue) but there's no masonry interaction nor redraw (I tried to use the prototype to trigger the redraw this.$redrawVueMasonry();).
So I don't know what's next to do. Continue finding a way to differentiate a prepend from a append and trying to bind it to the respective masonry's methods ? Or another method that I didn't think of...
Thanks in advance for you help
Ps : I don't think my code is really relevant since It's more a way to optimize the plugin. If you want some specific part of my code anymay, tell me in the comment !
This probably comes a bit too late, this being a 10 month old question.
However vue-masonry is able to handle situations where items are spliced anywhere in the array. But to properly update the grid this.$redrawVueMasonry() should be called inside this.$nextTick() like this:
this.$nextTick(() => this.$redrawVueMasonry());
Hope this helps, if not the original poster, someone else.

Xpages, Bootstrap and Data Views

I have a Data View in an Xpage application which is using the Bootstrap theme. I started to use a View, but could never get the pagers lines up, and the data view is working better.
But I do not understand where to put my table class css. For example, if I want a stripped table I enter "table table-striped" in the styleClass of the view (or maybe it is the dataStyleClass). If I do that in the styleClass of the data view, I do not get strips.
I tried the suggestion from Mark below, but something is not working. I added a script call and used the id of the tableview. It already has a class of "cleearfix table" on it.
I have added Chrome's web inspector to show what is going on.
The xe:dataView control does have a styleClass attribute, but classes that you set there are added to the div element that wraps the dataview, not the table (and that's where Bootstrap needs the table-striped class. I would solve this with some JavaScript to add the classes you need on the table element
<xp:scriptBlock
id="scriptBlock1">
<xp:this.value><![CDATA[
$("table.dataview").addClass("table-striped table-hover")
]]></xp:this.value>
</xp:scriptBlock>

Make button text A/B testable - Sitecore MVC

I have an MVC/angularJS page with a button, the button needs to call code to process the current page and proceed to the next step in the application, but they want the button text to be a/b testable with different variations. I'm new to Sitecore so am struggling to know the best way of doing things.
I thought of having a simple text component/template which just has a single line text property, but if I add that to the page template then it doesn't seem a/b testable because when you click on the test option it asks you to select content. Whereas the content was text they entered as part of the page template.
The only way I know of making a/b testable content so that they can click on the page in page editor and choose to select content / add test variation. I wouldn't add the button to the placeholder as it needs to call specific angular code and always be there, but should I be adding a placeholder where the text is? It seems like overkill to have to define a placeholder there, define a rendering, create a partial view, define placeholder settings to limit it to the simple text component, and then hope they don't try adding multiple items to the placeholder.
I would make a separate template (ie with the text field for your button) to represent your form, then either create the two test variation items as children of your page, or maybe place them in a shared components folder outside of your 'home' node.
EDIT
In order to move your form component into a new A/B testable component you would need to create a new Sublayout in Sitecore, then create a new ascx control for the sublayout. In the Page_Load handler of this control, you would use the following code to retrieve the datasource of the sublayout:
//assume you have a button on your usercontrol called btnSubmit
//assume your template has a single-line text field called 'SubmitButtonText'
Guid dataSourceId;
Sitecore.Data.Items.Item dataSource;
if (Guid.TryParse(sublayout.DataSource, out dataSourceId))
{
dataSource = Sitecore.Context.Database.GetItem(new ID(dataSourceId));
btnSubmit.Text = dataSource["SubmitButtonText"];
}
So I created a new template which just had a single line of text as a field, and added a content item in a shared data node.
In my partial view:
#model Digital.Models.SimpleTextItem
<button ....>
<span class="hidden-xs">#Model.SimpleText_Value<br></span>
</button>
In my main page - I was trying to statically bind it so that they could only change content rather than add new controls to the placeholder, but that only worked if I specified the datasource in this page.
Using a rendering, and in the page layout adding the rendering to the placeholder with a specified data source:
#Html.Sitecore().Placeholder("PremiumQuoteApplyNowPlaceHolder")
Not sure if it was the best approach but it achieves what I need it to.
A/B testing could be applied only to controls(XSLT renderings, sublayouts, action controller renderings, view renderings). If you want to make A/B testing only for button then you should create additional control for it as you did.
Technical details for MVC: A/B testing is applied on mvc.customizeRendering pipeline where rendering arguments are processed. This pipeline operates on renderings level. It means that you are not able to create A/B testing for particular field(button) without your own customization.

Insert newly added Item at the top of an EnhancedGrid in Dojo

I have an EnhancedGrid which is bound to a dynamic Store. I am using lazy loading, so as I scroll down, more data will be fetched and bound.
I also have an "add new Item" functionality. This will open a pop-up where the user creates the new Item in a form, and on Save the item is added to the store. with dojo.data.ObjectStore.newItem() and dojo.data.ObjectStore.save().
My problem, after using those two functions, the item is automatically appended to the grid at the bottom, which is kinda of a nuisance. The user will have to scroll down to find it, which would trigger the lazy loading.
After following the code around, I found out that newItem() calls the dojox.grid.DataGrid._addItem(item, index, noUpdate) function.
I managed to overwrite it so when I am adding a new item, the _addItem function will be called with index 0. But that does not work since it was just replacing the first row with the new one instead of prepending it.
Is there any other way to look at this? is it possible to actually do it?

Trying to make dynamically created element draggable

I'm trying to create a dynamic input element that is draggable. Now the problem is I create an element but when I use something like
$("#in"+index.toString()).draggable({cancel:true});
after I append it to the container div, it's not working. Basically it's not working for the dynamically created input element of a certain id. Here's the code and please feel free to point out problems. I could really use some help on this one. Thanks!

The problem is that you are creating a new element that is not bound to the UI functions. I would suggest using clone(true,true) and then changing the parameters of the cloned element as need be. You can learn more about clone here. http://api.jquery.com/clone/
