@jeffalo how did you detect the origin of a pasted image (it only works from cubeupload or imgbb. i thought copied images only include the image data)
i have no idea.
tiptap does it and its not even intentional. admins have a button for image by url, and i didnt know tiptap would even paste images in, somehow it works.
apparently event data transfers have that data. like this code (pasted from stackoverflow):
target.onpaste = (e) => {
const dT = e.clipboardData || window.clipboardData;
const html = dT.getData('text/html') || "";
const parsed = new DOMParser().parseFromString(html, 'text/html');
const img = parsed.querySelector('img');
if( !img ) { console.warn('no image here'); return; }
const url = img.src;
console.log(url);
};
