As we all know ,Data Elements can store values from your own data layer object, cookies, local storage objects, query string parameters, page elements, meta tags, etc. It was designed to return a value for use across page load, event triggered and direct call rules, and validity period depends on Storage Duration.

But one is special. Constants, its value are constant,. There are ten data elements that can pass dynamic values:

  • Cookie
  • Custom Code
  • DOM Attribute
  • JavaScript Variable
  • Local Storage
  • Page Info
  • Query String Parameter
  • Random Number
  • Session Storage
  • Visitor Behavior

Let’s take a look at how to use them one by one.

Cookie

Cookies: Cookies can be read into stored data elements, only first-party cookies can be read. It can be used later by Rules and Extensions.

For example, open my blog http://www.bbccss.com, and then open the developer tools, find Application, click on it, and then click on the Cookies on the left. All the cookies shown here are cookies:

Note the Domain column, some of them belong to my domain name bbccss.com, these are first-party cookies, some are of other domain names, these are third-party cookies, such as doubleclick.net shown in the figure above.

The cookie in the data element can only capture the first-party cookie. Now suppose I want to capture the _ga cookie. The settings in Launch are as follows:

Custom Code

Custom code can process the data through js and then return the value.

For example, this can be used to classify the page, and this data element can be referenced by the Channel.

DOM Attribute

DOM Attribute can scrapes a value from the DOM.  The values on the page can be fetched this way.

For instance, I want to crawl Slogan of my blog:

#header> div.container-inner> div> a> h1> span.g-bloger(Css Selector) is the positioning page element, and text is telling Adobe Launch which value to get.

JavaScript Variable

JavaScript Variable, everyone should be familiar with this, this is the previous data layer.

Some data layers look like this:

But their structure is the same, they all store some key-value pairs in <scripts> </ scripts>. All the information in this can be obtained through JavaScript Variable.

The configuration of the first way is as follows:

In fact, there is a lot of information that can be obtained this way. Open your browser’s dev Tools window. Click on the Console tab at the top and type window:

All the information you see can be passed in via JavaScript Variable.

 

Local Storage

This is a bit like a cookie, but has a longer storage period. LocalStorage is a type of web storage that allows Javascript websites and apps to store and access data right in the browser with no expiration date. This means the data stored in the browser will persist even after the browser window has been closed.

We can see what information is stored in Local Storage. Open my blog, then open the developer tools, select Application, click LocalStorage:

This information is stored in Local Storage,Unlike cookies, Web Storage (Session Storage and Local Storage)data does not get passed to the server unless you actively pull the data out of storage and send it.

Every data element value that Launch stores has a key that begins with com.adobe.reactor.dataElements..The structure is com.adobe.reactor.dataElements. + Item, you don’t need to fill in the whole, you only need to fill in the items, for example, I want to get com.adobe.reactor.dataElements.Cookie-ga, set as follows:

Page Info

A lot of built-in Page Info information can be used by Rules and Extensions just by configuring it.

Query String Parameter

Query String Parameter can get some key-value pair information on the URL. Is to get the information on the url to pass to the data element.

For example, the URL is https: //www.bbccss.com&cid=google. I want to get the value of Google. I can set it like this:

If you pay attention, you will find that Visitor Behavior is similar to Local Storage and Session Storage information, because Visitor Behavior is obtained using Web Storage (Local Storage and Session Storage)

The setting method is as follows:
