![]() Similarly, if nnect() is called, then the onConnect event may be fired multiple times, once for every frame in the extension process. If there are multiple frames in a tab, calling nnect() results in multiple invocations of the runtime.onConnect event, once for each frame in the tab. This port can immediately be used for sending messages to the other end via postMessage(). Upon calling nnect(), nnect() or nnectNative(), a Port is created. Ports are designed as a two-way communication method between different parts of the extension, where a (top-level) frame is viewed as the smallest part. Here is how you open a channel from a content script, and send and listen for messages: When establishing a connection, each end is given a runtime.Port object which is used for sending and receiving messages through that connection. The shared connection allows the extension to keep shared state linking the messages coming from the content script. The content script could open a channel to the extension page for a particular login, and send a message to the extension for each input element on the page to request the form data to fill in. One use case might be an automatic form filling extension. The channel can optionally have a name, allowing you to distinguish between different types of connections. In this case, you can open a long-lived channel from your content script to an extension page or vice versa using nnect or nnect, respectively. Sometimes it's useful to have a conversation that lasts longer than a single request and response. For information on converting callbacks to promises and for using them in extensions, see our own article. The sendMessage() function's callback will be invoked automatically if no handlers return true or if the sendResponse() callback is garbage-collected.įor information on using promises, see Promises on MDN. If you're using callbacks, the sendResponse() callback is only valid if used synchronously, or if the event handler returns true to indicate that it will respond asynchronously. All other responses to that event will be ignored.įor new extensions you should prefer promises over callbacks. If multiple pages are listening for onMessage events, only the first to call sendResponse() for a particular event will succeed in sending the response. Sending a request from a content script looks like this: You cannot use both a promise and a callback. For backward compatibility, you can alternatively pass a callback as the last argument. To handle the response, use the returned Promise. This lets you send a one-time JSON-serializable message from a content script to the extension, or vice versa. If you only need to send a single message to another part of your extension (and optionally get a response back), use the simplified ndMessage() method or ndMessage() method. That is covered in the cross-extension messages section. It is also possible to send a message to another extension if you know its ID. ![]() There is a simple API for one-time requests and a more complex API for long-lived connections to exchange multiple messages within shared context. A message can contain any valid JSON object (null, boolean, number, string, array, or object). Either side can listen for messages sent from the other end, and respond on the same channel. For example, an RSS reader extension might use content scripts to detect the presence of an RSS feed on a page, then notify the background page in order to display a page action icon for that page.Ĭommunication between extensions and their content scripts works by using message passing. Since content scripts run in the context of a web page and not the extension, they often need some way of communicating with the rest of the extension.

And I learned a new MONTALBAN! Paolo was totally unfamiliar to me. THUMB WARS made me laugh (haven't thought of those in years), and the clue on that one was especially nice ( 48A: Digital confrontations?) (your thumb is the "digit" in question, though you probably know that by now). " WE DID IT!" is a great, exultant little way to hide "WED.," and it makes a nice grid centerpiece. Also, what the hell else are you gonna use for your TUE- answer? The only other things I can think of are also French phrases. TU ES BELLE is probably the biggest reach-you don't usually get foreign phrases of that length in a grid, so it seems like it could really trip up non-French speakers-and yet it's also the most inventive themer of the lot. But all the midweek stuff really lights up. and that SATAN's just chilling at the very bottom, where he's probably most comfortable). ![]() SUNNI and SATAN are throwaways (though I like that they're both. That is, it's the themers that gave the grid many of its most interesting answers. I was like "okay, cool, a really bouncy mid-week themeless, let's go!" But then of course there was a theme, and the theme was a big part of *why* the grid was so good. ![]() Which brings me to what is perhaps a point I should stress more often-the higher the overall quality of the fill, the less the exact nature of the theme even matters. I didn't really care what the "7" stuff was supposed to be about because I was just enjoying the ride. By the time I realized what the theme answers were doing, the grid had already sold me. I feel certain I've seen this theme before, or something like it, but the grid is so sparkling and shimmery that I didn't have a chance to care. ![]() Johnson has also made significant efforts to downplay and rewrite the events of January 6, claiming Sunday that the riot was not an armed insurrection because people had stayed “within the rope lines” in the Capitol. In response to YouTube’s decision to suspend his channel, Johnson told CNN, “YouTube’s ongoing Covid censorship proves they have accumulated too much unaccountable power.” Johnson, who tested positive for coronavirus last fall, said at the time that he was “sticking up for people who choose not to get vaccinated.” As of March, Johnson told CNN he had not yet been vaccinated because he previously had Covid-19. In May, CNN fact-checked Johnson’s false statements suggesting Covid-19 vaccines were dangerous and potentially deadly. This is not the first time Johnson has made false claims regarding the coronavirus. In the video, Johnson voiced support for using hydroxychloroquine against the virus, the same drug Trump enthusiastically endorsed and used as a preventative treatment for coronavirus last year.įacts First: The US Food and Drug Administration does not recommend using the drugs mentioned by Johnson for treating the coronavirus and warned against using hydroxychloroquine as early as July 2020 – two weeks after it revoked an emergency use authorization for using hydroxychloroquine to treat the virus – due to heart rhythm risks. On Friday, YouTube suspended Johnson’s account after it posted a video of the senator making dubious claims about treatments for the coronavirus. Johnson has been one of the most prominent Republican senators this year to make false and incorrect claims – often repeating narratives touted by former President Donald Trump and his allies – over the pandemic and the Capitol riot. The senator faced online punishment Friday after making false claims over treatments for Covid-19 and, over the weekend, downplayed the events of the January 6 riot during an interview on Fox News. Ron Johnson’s penchant for spreading false claims and misinformation shows no signs of stopping after a week in which he touted falsehoods related to both the January 6 Capitol riot and Covid-19. ![]() ![]() Merck reports that German Shepherd Dogs and Bull Terriers are known to spin or tail chase, while a genetic locus for flank sucking has been identified in Doberman Pinschers. Further research showed that the structural brain abnormalities of Doberman Pinschers afflicted with CCD are similar to those of humans with OCD. The Cummings School of Veterinary Medicine at Tufts University, in conjunction with other medical universities, identified a chromosome that confers a high risk of susceptibility of compulsive disorder in breeds. Jerry Klein, AKC chief veterinary officer, although any breed may develop a compulsive disorder, certain breeds seem to be more susceptible to specific types of compulsive behaviors. Research into the causes of compulsive behaviors in dogs is ongoing, and one area being studied is the genetic link. However, the Merck Veterinary Manual says, “they (dogs) do perceive and experience concern therefore, the term obsessive-compulsive has also been used to describe this disorder in dogs.” What Causes OCD in Dogs? There is an ongoing debate about whether dogs are actually capable of obsessing or having their thoughts completely focused on a behavior like people can – hence the change in naming the disorder in dogs to CCD. But if a dog wants to chase and retrieve or spin for many hours each day to the exclusion of other behaviors, and just can’t seem to stop, it’s time to seek advice from your veterinarian. It’s not so much what they do, but the extent to which they do it and their ability to control when they start and stop.įor example, there’s nothing abnormal about a dog who retrieves a ball over and over or spins when excited. The key is that they do it in expected situations, stop after a short time, and are able to rest and eat normally. You may be thinking, “Oh, no! My dog does lots of these things.” Many dogs bark a lot, chase their tails, spin when they’re happy, and bite at flies. It’s identified by normal dog behaviors that are performed in such an extreme, repetitive way that they are difficult for the dog to stop and can interfere with the dog’s ability to function.Įxamples of normal dog behaviors that in some dogs have become compulsive include sucking on their flanks or a toy incessant licking, called acral lick dermatitis pacing, spinning, and chasing the tail freezing and staring snapping at flies or invisible items unabated and patterned barking and excessive drinking of water or eating dirt. Obsessive Compulsive Disorder (OCD) in the dog world is also known as Canine Compulsive Disorder or CCD. |
