Chrome扩展程序：获取引用标签

Question

我如何知道是否通过其他标签页上的链接或内容脚本打开了标签？
如果我可以，我也需要该选项卡的信息。

chrome.tabs.onCreated.addListener(function(id, info, tab){
      //  tab doesn't contain any such info
});

Answer 1

您的回调格式错误。

根据documentation，回调需要一个Tab参数，而不是三个。

chrome.tabs.onCreated.addListener(function(tab){
  // You now have things like tab.id exposed
  // If you have "tabs" permission, also things like tab.url

  // You also have tab.openerTabId for "referrer" tab

  // If you have host permissions for the tab:
  chrome.tabs.executeScript(
    tab.id,
    { code: "document.referrer;" },
    function(result) {
      // Here, you have the "real" referrer,
      // which would be empty for tabs opened via `chrome.tabs`
    }
  );
});
