Add Active Class When Specific Variables Equal on React
In React, you can conditionally add an “active” class to an element based on certain variables using conditional rendering. In your code snippet, it appears that you want to add the “active” class to a list-group-item
element when the invoiceId
is equal to invoice.number
. Here’s how you can achieve this in React:

In the code above:
-
We assume you have a component called
YourComponent
that takesinvoiceId
andinvoice
as props. -
Inside the
return
statement, we use a template literal to create theclassName
dynamically for thelist-group-item
element. We use a conditional (ternary) operator to check ifinvoiceId
is equal toinvoice.number
. If they are equal, the ‘active’ class is added; otherwise, an empty string is added. -
This approach ensures that the “active” class is only added to the
list-group-item
when the conditioninvoiceId === invoice.number
is met. If the condition is not met, no additional classes will be added.
Make sure to replace YourComponent
with the actual name of your component and ensure that invoiceId
and invoice.number
are correctly passed as props to your component.
