EvaluateJsAction

Evaluate JavaScript code on the current page and return the result

Useful for extracting structured data from a page without LLM processing.

The code is evaluated as a JavaScript expression. For simple cases use a single expression. For multi-statement logic, use an IIFE (Immediately Invoked Function Expression): (() => { /* statements */ return result; })()

You will not get any output from console.log(), so simply use the return value if your goal is to gather information

Example:

session.execute(type="evaluate_js", code="document.title")
session.execute(type="evaluate_js", code="Array.from(document.querySelectorAll('a')).map(a => a.href)")
session.execute(type="evaluate_js", code="(() => { const els = document.querySelectorAll('a'); return els.length; })()")

Fields

category · str · default: "Special Browser Actions"

description · str

code · str · required
