I write custom validation scripts for landing pages. Well versed in Javascript.
Below are some examples of scripts I have written:
- If user input matches string, reject and display custom error
- If user selects Value A, and Value B, from two different fields, display custom error
- Pull parameters from browser URL, append onto object (iframe, a tag, etc)
I also setup any Unbounce solutions regarding scripts, if you need to implement for example a DOB calendar popup, smooth scrolling, etc.
