jsRendering

Use to force the engine to render the page with Javascript

=IMPORTFROMWEB(data_sources, selectors, "jsRendering")

or

AB
1jsRenderingTRUE
2
3=IMPORTFROMWEB(data_sources, selectors, A1:B1)

For speed and resource consumption purposes, the engine does not run JavaScript on a page by default. You may need it if the function does not output the expected results.
You can also guess when a webpage uses Javascript: typically when a spinner is displayed while waiting for the data to load.

Note that rendering JavaScript content will generally take more time. If 30 seconds have passed, the function displays #PENDING_REQUEST while our server fetches the page.
