Lines marked → were executed in headless Chromium against the markup above, and each result was compared with the value shown. Lines marked e.g. are illustrative.

Know the limits

• A URL taken from user input is an open redirect, and a javascript: URL runs code. Accept only relative paths or an allow-list of origins.
• location.assign adds a history entry; location.replace does not. The test uses a fragment, which navigates within the page.

The function above is the code the usage lines run. It does not validate its arguments; add checks where it receives untrusted input.

Keep exploring

• Check if a given DOMRect is contained within another DOMRect — True when the target lies inside the container or on its edges.
• Check if two DOMRects intersect — Two rects intersect when they meet on both axes.
• Compare two DOMRects for size and position match — Compare x, y, width and height exactly.
