I have the opposite question.
Suppose the *webpage* does something like:
if (!PIP.HOLD) {
PIP.HOLD = {};
}
(function () {
PIP.HOLD.summaryFields = [
'checkbox',
'title',
'author',
'status',
'holdPickupDate',
'holdPickupBranch',
'queuePosition',
'available'
];
})();
And I want to change PIP.HOLD.summaryFields to:
PIP.HOLD.summaryFields = [
'checkbox',
'title',
'author',
];
How can I do that from a Greasemonkey script?
