WTF is expression ? 🚧
Learn what a JavaScript expression is — push Superform to it's limits.
The sf-react attribute uses an expression to determine what text to display or what class and/or visibility to toggle dynamically.
This expression can be a simple JavaScript snippet that may include special variables ($f, $v, $s, $p) provided by Superform, but it’s not limited to them.
What is an Expression?
Simple JavaScript Snippet: The expression is essentially a small piece of JavaScript code that is evaluated to produce the text content. It can be as simple as referencing a form variable or as complex as a combination of them with standard JavaScript operations.
Form Variables: You can include variables like
$f(form inputs),$v(scoring variables),$s(step index), and$p(progress percentage) within your expression to dynamically display data from your form.Without Variables: The expression can also be a static string or a JavaScript operation that doesn't directly reference form data, providing flexibility in content display.
