How to insert HTML code before elements with a given class before converting

For Zapier, Integromat and others plugins insert custom profiles into profiles field. For API calls please set value as string in profiles parameter as string.

The profile below inserts HTML code before each h2 element. The inserted code will also force new page for printing for at the place of every h2 header. For example, if you take any Wikipedia page url, this profile will turn every h2 header into new page break.

For direct API calls set profiles param as string to the following:

{
     "CustomScript": "document.querySelectorAll('h2').forEach( elem => { elem.insertAdjacentHTML('beforebegin', '<div style=\"clear: both; page-break-after: always;\">INSERTED BEFORE H2 ELEMENT</div>') } )"
}

For Zapier, Integromat and others set profiles field to the following:

{
    "CustomScript": " document.querySelectorAll('h2').forEach( elem => { elem.insertAdjacentHTML('beforebegin', '<div style=\"clear: both; page-break-after: always;\">INSERTED BEFORE H2 ELEMENT</div>') } )"
}
