Set variable

The "Set variable" block allows you to set a particular value to a variable.

Set variable

This value can be any kind of plain text but also Javascript code.

Expressions with existing variables​

It means you can apply operations on existing variables.

Add a value to your variable:

{{Score}} + 5

Compute a sum of variables:

{{Score}} + {{Answer}}

Multiply variables together:

{{Score}} * {{Multiplier}}

Compute a percentage:

{{Score}} * 100 / {{Max Score}}

Current Date​

You can create a Submitted at (or any other name) variable using this code:

new Date().toISOString()

It will set the variable to the current date and time.

Random ID​

Or a random ID:

Math.round(Math.random() * 1000000)

Current URL​

A popular request also is to set a variable to the current URL. Here is the value that should be inserted:

window.location.href
caution

It will not give you the parent URL if you embed the bot on your site. A more bulletproof option is to pass the URL as a hidden variable in the embed code options. You can find an example here.

This code allows you to extract the value of a cookie called "my_cookie":

const getCookie = (name) => {
  const value = `; ${document.cookie}`
  const parts = value.split(`; ${name}=`)
  if (parts.length === 2) return parts.pop().split(';').shift()
  return 'not found'
}

return getCookie('my_cookie')

As you can see the code can also be multi-line. The Set variable block will get the value following the return statement.
