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 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'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")
we're are trying to match the data collection from our pre-DTM tag manager. We had custom data for the Adobe Analytics pev2 query parameter. Specifically, set to the same variable as the eVar and the Prop. I have tried setting s.pev2 in custom page code in the AA section of DTM without success.
var trackingString = s.pageName + '|page_nav|' + this.href;
s.linkName = trackingString;
Am I headed in the right direction, or is it not possible to customize this parameter?
You are headed in the right direction, but the approach is off.
You should create a Data Element within DTM to create the value that you want to place into the variable. Then use that Data Element to populate that var.
By chance, I discovered that selecting Custom Link in the Link Tracking portion of the Adobe Analytics section. Then setting the Link Name field to my trackingString variable sets the value of pev2.
I have the below code in my web site.
I want to track each anchor tag using DTM. I know how to track single element. Since here we have a bunch of different elements, can anyone help how to track them using DTM? I don't want to create separate rule for each element. In a single rule how can we track these elements.
Here is an example of what you can do.
For Element Tag or Selector put "a.at-share-btn" (no quotes). This will target all the relevant links first. We can look for this too in the next step, but "pre-qualifying" it with this will improve performance so that the rule is not evaluated against every single a click.
Then, under Rule Conditions, add a Criteria of type Data > Custom.
In the Custom box, add the following:
var shareType = this.getAttribute('class').match(/\bat-svc-([a-z_-]+)/i);
if (shareType&&shareType[1]) {
_satellite.setVar('shareType',shareType[1]);
return true;
}
return false;
This code looks for the class (e.g. "at-svc-facebook") and puts the last part of it (e.g. "facebook") into a data element named shareType.
Then, you can reference it using %shareType% in any of the DTM fields. Note: because this data element is made on-the-fly, it will not show up in the auto-complete when you type it out in a field.
Alternatively, in custom code boxes (e.g. if you are needing to reference it in a javascript/3rd party tag box), you can use _satellite.getVar('shareType')
