How to disable reactive form property in angular 2 - angular2-forms

I have one reactive form and i take one array inside form my implementation is like
testForm:FormGroup;
fb is instance of FormBuilder;
this.testForm=this.fb.group({
testarray:this.fb.Array([
note:['']
])
})
I am using above array on my html to display note. Here functionality is like user can add multiple note.
I want to disable and enable note of array when i post not at that time want to identify which not is posted and need to disable that note.
Here my question is how can we disable reactive form array property using angular 2 typescript?
Please help me
Thanks

For starters this:
testarray:this.fb.Array([
note:['']
])
is not valid syntax, you're trying to assign a note property to an array. I think what you want is this (also notice the lowercase a in array):
testarray: this.fb.array([
this.fb.control('')
])
Then when you want to disable a control in the array you can simply call .disable()on it.
So let's say you have a control:
const myControl = this.testForm.get('testarray').controls[0];
You would do
myControl.disable();

RxSwift - Class property's binding

I have an question about binding:
I have an array of objects of my custom class: Array. Every object can be updated (change his properties value) in bg.
Also I have separated Controller, which take and store one object from list as variable and can update it (object still the same, so in list it will be updated too)
Is there any way to bind all object.property -> UILabels on Controller in way, when property changes automatically call label update?
Of course, there are multiple ways how to do it, but from your description I would use some kind of subject (because u said there will be changes in background so you will probably need hot observable )....For example Variable or PublishSubject. So you can crate
let myArrayStream: Variable<[MyObject]> = Variable([])
you can pass this variable as dependency to wherever you want, on one side you can subscribe to it, on the other side you can update it's value.

How do you get the value of a data attribute within an event-based rule in Adobe Dynamic Tag Manager (DTM)?

I have an event-based rule configured to fire on click of an element with a specific class. On click, I would like to capture the value of a data attribute that exists. The DTM documentation says you can capture attribute values using this syntax:
%this.data-event%
or
%this.id%
Example HTML:
On click of links with the class "test", I would like to store the value of "event name" within an eVar. When I used the above syntax however, the syntax is converted to a string and in the Adobe server call as:
v25:%this.data-event%
What is the best way to dynamically grab the value of an attribute of an HTML element on click within DTM?
DTM documentation says you can do that, but in practice I too have found that it doesn't seem to work as advertised most of the time, and will instead populate it with a literal (un-eval'd) string like that.
So what I do instead is under Conditions > Rule Conditions I create a Custom condition. In the Custom condition, I add the following:
// example to get id
_satellite.setVar('this_id',this.id);
// example to get href
_satellite.setVar('this_href',this.href);
return true;
Basically I create on-the-fly data elements using javascript, and then return true (so the condition doesn't affect the rule from triggering).
Then I use %this_id%, %this_href%, etc. syntax from the data element I created, in the Adobe Analytics section variable fields.
The easist way to capture the values of a data attribute against an eVar or prop on the element clicked using DTM is to set the input as the following:
%this.getAttribute(data-attributename)%
For example, if there was a data attribute on an element of data-social-share-destination='facebook' simply input %this.getAttribute(data-social-share-destination)%. This will then capture the value of 'facebook'
More detail on data attributes can be found at http://www.digitalbalance.com.au/our-blog/event-based-tracking-using-html5-custom-data-attributes/
I found a solution. The best way to grab the value of an attribute on click is to use this syntax:
%this.getAttribute(data-title)%
The key is to not use quotes around the attribute name AND ensure the attribute has a value.
If the attribute is missing, the expression is not replaced by an empty string as one would normally expect from experience in other platforms, but instead will display the raw un-interpolated code.

Big Commerce Custom Fields

I'm planning on allowing a client to provide a couple codes for each product that I'll need to reference with Javascript on the product pages.
Basically my plan was to use the Big Commerce's 'custom fields' to do so, but I'm having trouble spitting out the custom fields onto the product pages. I've been looking all over for some type of GLOBAL variable that allows me to reference custom fields, but I'm coming up dry. I would think there would be some type of GLOBAL array with all the custom fields in it, or a way to reference them by name directly.
Am I blind, or is there just no way to do this directly in the BC template file?
Thanks.
In Bigcommerce the custom fields can generally be found within the ProductOtherDetails.html Panel which contains a Snippet named ProductCustomFieldItem.html. This snippet has the markup for each custom field that the system outputs.
Inside of the ProductCustomFieldItem.html Snippet are the two codes you are looking for: %%GLOBAL_CustomFieldName%% and %%GLOBAL_CustomFieldValue%%.
I ran into this as well - given that it's quite a long time later, I'm supposing there's no better answer - a decent amount of searching turned up nothing useful as it seems all you can do is output the full set of custom fields as a set of divs.
So, I output them into a div which was hidden:
<div id="fpd-custom-fields" style="display:none;">
%%SNIPPET_ProductCustomFields%%
</div>
and then set up a javascript function to get the value based on the name:
function getCustomFieldValue(label)
{
var value = '';
$('#fpd-custom-fields div.Label').each(function()
{
if($(this).text().toLowerCase() == (label.toLowerCase() + ':'))
{
value = $('div.Value', $(this).parent()).text().trim();
}
});
return value;
}
Doesn't feel quite right as it's not a very clean solution, but was the best I could come up with unfortunately!

How to localize selectOptions on the visual force page

I am trying to localize selectOptions on the Visual Force page.
Here is the .class code snippet:
List<SelectOption> options = new List<SelectOption>();
List<MyOption__c> dropDownValues = [SELECT Id, Display_Label_Name__c FROM MyOption__c];
for (MyOption__c val : dropDownValues) {
// Display_Label_Name__c field is the label from *.labels that needs to be translated
options.add(new SelectOption(val.Id, val.Display_Label_Name__c));
}
Here is the .page code snippet:
<apex:selectList value="{!myVal}">
<apex:selectOptions value="{!options}"/>
</apex:selectList>
Right now the dropdown displays the Display_Label_Name__c verbose. I am trying to see how I can display the translated version from the .labels file. Is it possible? If not, what's the work around?
Thank you for your responses!
All localisation of page text can be done with Custom Labels.
Enable the translation workbench with the languages you require.
Create labels for all the localisible text on the page.
Replace the page text with the labels.
Add a translation for each label.
Change your profile langauge to test.
But for your case you pull the select option text from a custom object. If the values of the select list are not expected to change frequently, less than once a week or so, then I would change to using custom labels.
Otherwise, you lose the value of Salesforce automatic language selection and have to implement something yourself.
I would recommend extending the custom object MyOption__c to have columns for all the supported languages. You could use an if/else block or dynamic apex to select the select option text.
Sample using Dynamic Apex
string language = ParseForSupportedLangauges(UserInfo.getLanguage()); // includes __c
list<sobject> dropDownValues = Database.query('SELECT Id, '+language+' FROM MyOption__c');
for (sobject val : dropDownValues) {
options.add(new SelectOption(val.get('Id'), val.get(language)));
}
ParseForSupportedLangauges() would be a custom method that checks for supported languages and assigns the default when necessary.
EDIT
Turns out there is a solution: Don't look for something until you need it, right?
Introduced in Spring '12 is the ability dynamicaly select the label to display suing array syntax. Also, the ability to create visualforce components from the controller was added but using the array syntax would be sufficient for your problem. This method would allow you to select the labels you want by using the query results from MyOption__c.
Using a repeat in visualforce to loop over the query results
<apex:repeat value="{!displayResultsValues}" var="labelName">
<apex:outputText value="{!$Label[labelName]}"/>
</apex:repeat>
Here is a good article to show the usage and syntax.

how to set Personalizable attribute to generic list in webpart?

I develop web part with custom editor part and faced with this question.
Is it possible in web part set Personalizable attribute to generic List?
For example I want something like this:
[WebBrowsable(false)]
[Personalizable(PersonalizationScope.Shared)]
public List<AnnouncementItem> Announcements
{
get { return _announcements; }
set { _announcements = value; }
}
Is it possible, and what kind of types at all can be used as "Personalizable"?
Thanks.
Solution:
I use a custom EditorPart to select multiple lists using AssetUrlSelector, but I need a way to personalize this collection for end user.List<of custom objects> doesn't work, but I found that List<string> (and only string) work perfectly. So, I get required lists in EditorPart and pass their to the web part using List<string>.
Try using a custom EditorPart to add/remove items from the collection. I've never built a web part that personalized a collection so I don't know if it works but I'd definitely try the collection with an EditorPart. If it doesn't work, serialize XML into a string property.
Your question does not seem to match your code. Your code shows a collection of custom objects. I doubt an end user will be able to set such a property. To have a property that points to a generic list, you would probably be better off defining the property as a string that contains the URL to a list.
