Adobe plug-in: inList

The inList plug-in allows you to check if a value already exists within either a delimited string or a JavaScript array object. Several other plug-ins depend on the inList plug-in to work. This plug-in provides a distinct advantage over the JavaScript method indexOf() where you it does not match partial strings. For example, if you used this plug-in to check for "event2", it won’t match with a string containing "event25". This plug-in is not necessary if you don’t need to check for values in delimited strings or arrays, or if you want to use your own indexOf() logic.

Install the plug-in using tags in Adobe Experience Platform

Adobe offers an extension that allows you to use most commonly-used plug-ins.

1. Log in to the Data Collection UI using your AdobeID credentials.
2. Click the desired property.
3. Go to the Extensions tab, then click on the Catalog button
4. Install and publish the Common Analytics Plugins extension
5. If you haven’t already, create a rule labeled “Initialize Plug-ins” with the following configuration:
   • Condition: None
   • Event: Core – Library Loaded (Page Top)
6. Add an action to the above rule with the following configuration:
   • Extension: Common Analytics Plugins
   • Action Type: Initialize inList
7. Save and publish the changes to the rule.

Install the plug-in using custom code editor

If you do not want to use the plug-in extension, you can use the custom code editor.

1. Log in to the Data Collection UI using your AdobeID credentials.
2. Click on the desired property.
3. Go to the Extensions tab, then click the Configure button under the Adobe Analytics extension.
4. Expand the Configure tracking using custom code accordion, which reveals the Open Editor button.
5. Open the custom code editor and paste the plug-in code provided below into the edit window.
6. Save and publish the changes to the Analytics extension.

Install the plug-in using AppMeasurement

Copy and paste the following code anywhere in the AppMeasurement file after the Analytics tracking object is instantiated (using s_gi). Preserving comments and version numbers of the code in your implementation helps Adobe with troubleshooting any potential issues.

Use the plug-in

The inList function returns a boolean depending on its inputs. It uses the following arguments:

• lv (required, string or array): A delimited list of values or a JavaScript array object to search
• vtc (required, string): The value to search for
• d (optional, string): The delimiter used to separate individual values in the lv argument. Defaults to a comma (,) when not set.
• cc (optional, boolean): If set to true or 1, a case-sensitive check is made. If set to false or omitted, then a case-insensitive check is made. Defaults to false.

Calling this function returns true if it finds a match, and false if it does not find a match.

Examples

// Returns true
s.events = "event22,event24";
if(inList(s.events,"event22")) {
    // Code will execute
}

// Returns false because event2 is not an exact match in the string
s.events = "event22,event24";
if(inList(s.events,"event2")) {
    // Code will not execute
}

// Returns true because of the NOT operator
s.events = "event22,event24";
if(!inList(s.events,"event23")) {
    // Code will execute
}

// Returns false because of the case-sensitive check
s.events = "event22,event23";
if(inList(s.events,"EVenT23","",true)) {
    // Code will not execute
}

// Returns false because of a mismatched delimiter, treating "events,eVar1" as a single value
s.linkTrackVars = "events,eVar1";
if(inList(s.linkTrackVars,"eVar1","|")) {
    // Code will not execute
}
