Feels like I'm missing something stupid here, but what's the recommended method to listen to the click event on a listview?
At the moment I've got:
WinJS.Utilities.query(".menuHolder").listen("click", linkClickHandler, false);
And my listview template uses the class 'menuHolder' for it's items:
<div id="menuTemplate"
data-win-control="WinJS.Binding.Template">
<div class="menuHolder">
<!-- menu img -->
<img src="#" data-win-bind="src : pic; alt : title" />
<div class="menuText">
<!-- menu text -->
<h1 data-win-bind="innerText : title"></h1>
<!-- menu desc -->
<h4 data-win-bind="innerText : description"></h4>
</div>
</div>
</div>
I don't seem to hit my breakpoint, in my link handler, or invoke it's function. Any thoughts?
EDIT:
As a follow on question (bearing in mind the item invoked event) is anyone aware of the recommended approach to pass data between a listview and the iteminvoked event, if I say wanted to use the WinJS.Navigator class to move around an application? I'm guessing I need to cast some part of the eventInfo into a suitable object and retrieve information, what part?
Assuming the data you want to "pass" is the data that is bound to the item that was invoked, you can do that in the event arguments that are passed in to the iteminvoked event. One of mine looks like this...
demosLV.oniteminvoked = function(e) {
e.detail.itemPromise.then(function(item) {
var location = format("/pages/{0}/{0}.html", item.data.key);
WinJS.Navigation.navigate(location, item.data);
});
};
So the demosLV is the ListView. I'm setting the oniteminvoked to a function. That function receives "e" as the event args. In the function I access e.detail.itemPromise and hang a .then off of it. Then I access the actual data in the .then using item.data.
Hope that's what you meant. BTW, the format function is one of mine in case you're wondering why it doesn't work for you.
Seems I was being a sausage, I needed to listen for the 'iteminvoked' event on the parent listview id reference, not the child level.
WinJS.Utilities.query("#menu").listen("iteminvoked", linkClickHandler, false);

Am having a AEM6 html component, am getting the values from dialog and using it inside the component via the .js file and using the return properties.
I could able to get the authored values but it is getting null or empty when am using it inside the onclick method. Please find below the code snippet below.
<div data-sly-unwrap data-sly-use.test="test.js"></div>
<a href="#" class="${test.testId}" id="${test.testId}" onClick="toggleDraw('${test.testId}')" >
The content I authored is getting displayed in class and Id, but it is not displaying in the onClick method.
Below is the Output am getting after authoring.
<a href="#" class="get-a-quote" id="get-a-quote" onClick="toggleDraw('')" >
Output I needed is :
<a href="#" class="get-a-quote" id="get-a-quote" onClick="toggleDraw('get-a-quote')" >
This should do the trick:
<a data-sly-test.variable123="toggleDraw('${test.testId}')" href="#" class="${test.testId}" id="${test.testId}" onclick="${variable123 # context='attribute'}" >
You need to put the function call in a variable because of the nested single quotes. And you need to manually set the context in this case. If "attribute" does some escaping you do not like, you could use "unsafe" - this will end in all escaping mechanisms being disabled. That might or might not be a security issue for your application.

I have a form, this form needs to post some data to my backend. With flux, what is the best practice for doing this, use a store?
My issue with using a store is that I have a sub component inside of my form that allows me to select a number 1-5 with buttons. I wanted that component to be reusable, but if i use a store, I have to hard code the store into the child component which means I cant really use it elsewhere. Instead do I just set the parent state from the child?
If anyone can point out some good tutorials or examples of react/flux forms let me know.
In my opinion any back end interaction should be done by using actions, but...
if you want to use store anyway then you can create additional attribute (prop) in your sub-component which will be a function (f.e. onChange) which should be passed from parent component as prop (this function should set data in store). Then you can reuse this component, because only parent needs to have access to store.
So in subcomponent:
onButtonClick(e) {
this.state.value = e.target.value;
if (this.props.onChange) this.props.onChange(e.target.value);
}
<div>
<button onClick={this.onButtonClick.bind(this)} value="1">1</button>
<button onClick={this.onButtonClick.bind(this)} value="2">2</button>
<button onClick={this.onButtonClick.bind(this)} value="3">3</button>
<button onClick={this.onButtonClick.bind(this)} value="4">4</button>
<button onClick={this.onButtonClick.bind(this)} value="5">5</button>
</div>
and in parent:
setMyStoreState(value) {
store.setNumber(value);
}
<Subcomponent onChange={this.setStoreState.bind(this)} />
or something like this.
Code not tested, but you should get the idea.
I have a view in my sapui5 app, where on a button press I want to pass some data to the controller, to the function invoked on the press event.
Below is the code snippet :
<HBox justifyContent="SpaceAround" alignItems="Center" >
<Input type="Tel" pattern="[0-9]*" inputmode="numeric"
value="{path:'cart>Quantity/value',
type: 'sap.ui.model.type.Integer'}"
class="qtyInput" editable="{cart>Quantity/isEditable}"/>
<core:Icon src="sap-icon://delete" press="deleteItem" visible="{cart>isDeletable}"/>
</HBox>
Here, I need to pass "{cart>lineNumber}" and ”{cart>itemKey}" to the function “deleteItem” which is there in the controller.
Please suggest.
You can try using sapui5 CustomData to pass your custom data on a event.
For that, you need to add below namespace in your view:
xmlns:app="http://schemas.sap.com/sapui5/extension/sap.ui.core.CustomData/1"
and add app:propertyName=“value” inside the Icon element.
Please take a look at below example, I updated your code with the changes required:
<core:Icon src="sap-icon://delete" press="deleteItem" visible="{cart>isDeletable}" app:lineNumber="{cart>lineNumber}" app:itemKey="{cart>itemKey}"/>
Thanks.
Another way to resolve this problem is, if you are getting the data from the same model on which the list is being iterated, you may get the index number of the list item and then read the specific record from the model itself using the index number.
Let me know if you need a code example for this.
I'm having a hard time trying to connect SUI modal with SilverStripe to generate them dynamically.
I want to achieve something like this:
I have button (attach events) to trigger modal with some content. I wanted to loop that elements (GridField) to generate everything dynamically. But the only thing I can achieve is multiple modals with the same "trigger class" and it doesn't matter which button I have clicked (first, last or whatever). I only have one modal (the last in hierarchy). Without SUI the solution is easy - put "this" to fetch the closest element and I can have as many different modals as I want, but SUI seems to complicate things.
I think the best solution will be to generate a class/id with SilverStripe and pass it to the JavaScript to use with modal or use one class for every modal and to "somehow inform" that this button triggers this modal.
Basically I need one code snippet to handle many modals, not many snippets to handle many modals. I hope it's clear enough what the the problem is.
Here is my code:
HTML/SS
(without specific SilverStripe tags)
<% loop SomeName %>
<div class="job-offers">
<a class="ui right floated button job-application">Click here</a>
</div>
<div class="ui basic modal job-application">
<div class="job-application-sheet">
(...)
<div class="job-application-sheet-content">
<div class="ui grid">
(...)
<div class="ui center aligned container job-application-action">
<p>Lorem ipsum</p>
<button class="ui primary button">Click here</button>
</div>
</div>
</div>
</div>
</div>
<% end_loop %>
JavaScript
$('.ui.basic.modal.job-application')
.modal({
autofocus : false,
observeChanges: true
})
.modal('attach events', '.job-application', 'show');
As you can see "job-application" class is a trigger for modal, so is this possible to change it to "(this)" so I don't have to write "specific" class for each button/modal. Or maybe there is a different/easier solution?
first i generated a data-type attribute for each of my elements that are going to display a modal when they are clicked, and in send as a local the same index to the modal this way:
<% #relateds_array.each.with_index do |related,i| %>
<div class="card custom" data-id="<%=i%>">
<%= render partial: 'my_modal', locals: {index: i} %>
</div>
<% end %>
the i put the modal in the partial that i called my_modal for this example and used the index that i sent as a local to create an unique id for each my modals, like this:
<div class="ui modal" id="modal-<%=index%>">
<p>blabla things inside this modal.</p>
</div>
and then with javascript, simply get the data-id of the element clicked and select the element that contain the id for that data-id, like this:
$('.element_that_you_want_to_open_moda_on_click').click(function(event){
var card_clicked = $(this).attr('data-id');
$('#modal-' + card_clicked).modal('show');
});
Hope this was useful for you.
Note that i used Ruby on Rails for this example, but the behaviour that you should use should be something similar to this, no matter what framework you use.
Answer based on Sebastian's solution. I did some minor tweaks to meet my needs, like I've used ID variable to automatically get DataObject ID which is generated dynamically.
Basically to dynamically add Semantic UI (SUI) modal in SilverStripe, first you should add "data-id" in a modal trigger, for example:
Template.ss
<a class="ui button custom-trigger" data-id="my-item-$ID">Click here</a>
then inside modal container add an "id" tag, for example:
<div id="modal-my-item-$ID" class="ui basic modal">
(...)
</div>
Finally in JavaScript file:
$('.custom-trigger').click(function(event){
var triggerItem = $(this).attr('data-id');
$('#modal-' + triggerItem).modal('show');
});
I meet problem with SUI autofocus, so after a modal opens, screen went to the bottom and button placed there was highlighted.
I tweaked original snippet adding SUI settings:
$('.custom-trigger').click(function(event){
var triggerItem = $(this).attr('data-id');
$('.ui.modal')
.modal({
autofocus: false,
observeChanges: true
})
$('#modal-' + triggerItem).modal('show');
});
If someone wants to write "data-id trigger" manually using fields in CMS, then change $ID to $SomeField variable. Then normally add that field in .php file and in Page Controller add something like this:
public function init() {
parent::init();
Requirements::javascriptTemplate($this->ThemeDir().'/js/script.js', array(
'SomeField' => $this->SomeField
));
}
Hope this helps someone.
I'm trying to use one of these:
http://www.eyecon.ro/bootstrap-datepicker/
However, I'd like it to be the main element, i.e. always be displayed, not hide when clicked away from, and not display the element it writes to. I can't find any documentation or examples on how to do this. Any ideas?
I'd like to use this datepicker if at all possible because it's what I use in other areas of the site (where a non-persistent picker is needed) and would like to keep things consistent.
<input type="text" name="startdate" id="date" />
<div class="date" data-altfield="#date"></div>
$(function(){
$('.date').each(function(i,e){
var $d = $(this);
$d.datepicker({
altField: $d.data('altfield')
});
});
});
