A function called inspectSlots
is also added. Invoking it parses the data-o-ads-*
attributes on each slot:
{
"name": "article-native",
"init": "true",
"targeting": {
"format": "stacked",
"image": "hidden",
"pos": "native"
},
"label": "true",
"formats": {
"default": ["false"],
"extra": ["false"],
"large": ["PartnerContent"],
"medium": ["PartnerContent"],
"small": ["PartnerContent"]
}
}
The easiest way to invoke it is via a bookmarklet. A preconfigured one that you can drag to your favourites is available at https://financial-times.github.io/advertising/.
Alternatively you can create a bookmark called "Inspect slots" and edit its address to read
javascript:window.postMessage({ type: "INSPECT_SLOTS" }, "*");
- Copy the root directory to your machine
- Follow these instructions for side-loading the extension:

npm i

:dist/
will now be rebuilt on changes to the source files - Apply your updates by clicking the "reload" button in the extension's settings (you won't see any changes without doing this)
- Constrain inspection to FT.com pages
- Tie requests back to the slots that triggered them
- Support copying parsed values to the clipboard
