I have some ExtJs component.
I set itemId for it, but id is autogenerated.
Now Ext.getCmp('autogenerated-id') returns my component.
But Ext.ComponentQuery.query('#autogenerated-id') returns an empty array.
But:
Ext.ComponentQuery.query('[id=assets-information-form-1918]') again returns my component. :)
I use ExtJs 6.5.3 classic.
It seems like itemId config property hides autogenerated id from Ext.ComponentQuery, so they become mutually exclusive.
I don't need other means for search or advice to set id for the component, to write letter to Sencha support or to write post on their forum.
I need:
Means to force my Ext.ComponentQuery.query('#autogenerated-id') to
find the Component for which getId() returns 'autogenerated-id'.
If it is not possible by design, I need a link to some documentation
describing this behavior, a link to some bug report, or a filename and line number in ExtJs sources + a little snippet copy/paste from there.
From the documentation
Summary Provides searching of Components within Ext.ComponentManager
(globally) or a specific Ext.container.Container on the document with
a similar syntax to a CSS selector. Returns Array of matching
Components, or empty Array.
Ext.ComonpentQuery.query('#itemId') returns and array. Your cold above is using the auto-generated id of the component. The # indicates to query based on the component itemId and not the component id.
Try
Ext.ComponentQuery.query('assets-information-form-1918');
which will return an array, as noted in the documentation.
Ext.getCmp()
This is shorthand reference to Ext.ComponentManager#get. Looks up an
existing Ext.Component by id
Therefore it returns the component object.
Ext.ComponentQuery.query('#itemId')[0] would return the first object in the array.
Ext.ComponentQuery is the Sencha preferred method because it is more powerful when used as it does return an array so you an also query items by xtype and other attributes.

I am using OData API to read data in my Fiori Application. The issue is, in Odata API, the latest data entry is at the end rather it should be at the top. How do i do that ie put my latest data on top.
You can use the $orderby to decide what order the data is returned in. See the docs for more info. This URL is an example of ordering (using the OData TripPin example service) that sorts by the LastName property:
http://services.odata.org/V4/TripPinServiceRW/People?$orderby=LastName
We can use this same process to order by a DateTime value or an ID value to get your latest entries at the top. For example, here we order by the DateTimeOffset field StartsAt putting the latest entries first:
http://services.odata.org/V4/TripPinServiceRW/People('russellwhyte')/Trips?$orderby=StartsAt desc

As mentioned before, you might have a look at server side sorting using “$orderby” as seen here.

You might also want to check out the following tutorial on Sorting:
“
items="{
path : 'invoice>/Invoices',
sorter : {
path : 'ProductName'
}
}"
We add a declarative sorter to our binding syntax.
As usual, we transform the simple binding syntax to the object notation, specify the path to the data,
and now add an additional sorter property.
We specify the data path by which the invoice items should be sorted, the rest is done automatically.
By default, the sorting is ascending, but you could also add a property descending with the value true inside the sorter property to change the sorting order.”
Please see here and here

This here might also be helpful:
“In this step, we will create a button at the top of the table which will change the sorting of the table.
When the current sorting state of the table is changed, the sorting state will be reflected in the URL.
This illustrates how to make the table sorting bookmarkable.”

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.
I've an array of objects containing title and salary which is used in typeahead directive.
I display department name and get entire object as value.
If none of the options match, I want user entered string to be converted to object still. Is there any way to update that?
This answer is pretty late, but I would just use ng-blur (to trap the end of the users input) along with a variable bound to typeahead-no-results. Then test if the variable is true in the method bound to ng-blur, and, if so, make an object out of the String supplied by the user and push it to your data source. Simple example found here.
In a Umbraco 7 solution, i have a Tags Content picker on all pages. Pages can with this, set tags on each page.
I then want to get alle pages, within the intire site, that has, lets say tag 111 (id, not name).
I have tried with:
var ids = Model.MacroParameters["tags"]; //the tags to show
CurrentPage.AncestorOrSelf(1).Descendants().Where(x => ids.Contains(x.tags.ToString()));
But that gives me the error:
Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type
Whats the correct way?
Solved it with;
Umbraco.Content(rootId).Descendants().Where("tags.Contains(#0)", ids);
You have a few options, depending on whether you prefer a dynamic or strongly typed view model.
Strongly Typed API
Umbraco.TypedContentAtRoot().Descendants().Where(x => x.tags.Contains(ids));
Dynamic API
Umbraco.ContentAtRoot().Descendants().Where("tags.Contains(#0)", ids);
Please note that the Contains statement may give you inconsistent results, as the tags property seems to be returning a comma separated list. In that case you can try splitting the string or install the Core Property Value Converters package and get the tags as IEnumerable<IPublishedContent>
Always try to avoid using Descendants, especially on the root node.
To get the tags for a property:
ApplicationContext.Current.Services.TagService.GetTagsForProperty(Model.Content.Id, "propertyname")
To find content with a specific tag:
ApplicationContext.Current.Services.TagService.GetTaggedContentByTag("tag")
https://hc.apache.org/httpcomponents-client-4.3.x/httpclient/apidocs/org/apache/http/client/utils/URLEncodedUtils.html#parse(java.net.URI,%20java.lang.String)
why not return Map< String, List< String > >
if it returns Map, user can easily query by key to get whatever they want.
otherwise user should iterator the whole list to find what they want.
Thanks
Because this is a list. If you read carefully the explanation, says:
Returns a list of NameValuePairs as built from the URI's query portion. For example, a URI of http://example.org/path/to/file?a=1&b=2&c=3 would return a list of three NameValuePairs, one for a=1, one for b=2, and one for c=3.
That means that you cannot use a list to acces by value, because these type of data structures aren't designed for that. They doesn't have any "key" to use.
In this website, Jon Skeet wrote a very clear answer about you cannot use a shortcut to acces a List<NameValuePair> value using a name or a key or for similar structures.
Here you can check the post: Get ArrayList<NameValuePair> value by name
Inside of the same post, you'll see different options to solve your problem. (Or could guide to you to find the solution)
