changeColor.addEventListener(“click on”, async () => {
let [tab] = await chrome.tabs.question({ lively: true, currentWindow: true });
chrome.scripting.executeScript({
goal: { tabId: tab.id },
perform: setPageBackgroundColor,
});
});
// The physique of this perform might be executed as a content material script contained in the
// present web page
perform setPageBackgroundColor() {
chrome.storage.sync.get(“coloration”, ({ coloration }) => {
doc.physique.fashion.backgroundColor = coloration;
});
}
perform setPageBackgroundColor() {
chrome.storage.sync.get(“coloration”, ({ coloration }) => {
