Javascript

Executes a javascript code on the client side.

Javascript is basically a piece of code that can be run on the browser to perform an action. Some of the cases where a Javascript action block can be used are:

• Performing maths calculations.

• Dynamically rendering the values of the variables.

• String modification.

• Firing & tracking events in Google Analytics.

You can choose to run the Javascript code either on CLIENT / SERVER.

Maths Calculations:

Here are few of the snippets that you can use to perform the maths calculations within the chatbot flow:

Parameter	Snippet	Description
Summation (Addition)	const additionResult = num1 + num2;	Num 1 & Num 2 can be any number or variable which has a number stored in it The result will be stored in additionResult variable
Subtraction (Minus)	const additionResult = num1 - num2;	Num 1 & Num 2 can be any number or variable which has a number stored in it The result will be stored in additionResult variable
Division (Divide)	const additionResult = num1 / num2;	Num 1 & Num 2 can be any number or variable which has a number stored in it The result will be stored in additionResult variable
Multiplication (Multiple)	const additionResult = num1 * num2;	Num 1 & Num 2 can be any number or variable which has a number stored in it The result will be stored in additionResult variable

Rendering values into variables:

Here are few of the snippets that you can use to render values in variables.

Parameter	Snippet	Example
Set Variable (Conversation)	wn.setConversationVariable(“variable_name”,”variable_value”); Or WotNot.setConversationVariables({“variable_name”:”variable_value”})	wn.setConversationVariable(“name_wn”,”ABC”); Or WotNot.setConversationVariables({“t1”:”123”})
Set Variable (Contact)	wn.setContactVariable(“variable_name”,”variable_value”); Or WotNot.setContactVariables({“variable_name”:”variable_value”})	wn.setContactVariable(“name_wn”,”ABC”); Or WotNot.setContactVariables({“t1”:”123”})

String Modification:

Here are few of the snippets that you can use to calculate the length of the variable or get part of the variable.

Parameter	Snippet	Example
Length of String	const lengthOfString = “variable_name”.length();	const lengthOfString = “some_string_content”.length(); //Output: 19 Calculates the number of characters passed/present in the value
Get part of a string	const partOfString = “variable_name”.slice();	const partOfString = “some_string_content”.slice(5); Note: We need to pass the starting index from where we need to get the sub-string. The index starts from 0. //Output: string_content Commonly used to pass the phone number without country code

Firing & Tracking events in Google Analytics or any Analytics tool:

Here is the snippet that you can use to push or record events into Google Analytics or any other analytics tool

Tool	Snippet	Example
Google Analytics 4	window.dataLayer = window.dataLayer || []; function gtag() { window.dataLayer.push(arguments); } gtag("js", new Date()); gtag("config", "YOUR-MEASUREMENT-ID"); gtag("event", "YOUR-EVENT-NAME", { "send_to": "YOUR-MEASUREMENT-ID" // Additional parameters that you may want to pass });	window.dataLayer = window.dataLayer || []; function gtag() { window.dataLayer.push(arguments); } gtag("js", new Date()); gtag("config", "123"); gtag("event", "WotNot_Test", { "send_to": "123", "name": "Test", "phone": "123456789", });

Triggering day-based flow:

Here is the snippet that you can use to trigger the flow based on specific day

Parameter	Snippet	Description
Get current date	const currentDate = new Date();	Helps to get the today’s date
Check if Fromdate should be more than Todate	isFromDateBeforeToDate(fromDate, toDate) { const fromDateObj = new Date(fromDate); const toDateObj = new Date(toDate); return fromDateObj < toDateObj; }	Helps to trigger the flow the day specific flow
