I think that was a mistake. WHATWG still mention onerror in their HTML living standard specification. Also, onerror attribute on img elements is not included in their obsolete features list.
I stucked in two kinds of error system pods running, found labels but still waiting for labels… xxxx: EOF I finally sovled it by following the advice by the following project, https://github.com/AliyunContainerService/k8s-for-docker-desktop/ Do as it told you, if not work, remove ~/.kube and ~/Library/Group\ Containers/group.com.docker/pki directory, then restart docker desktop and wait like 5 minutes. … Read more
When you design a function interface and there are errors to deal with, you have a design choice for how to return errors. If the function is synchronous, you can either return some sentinel value that indicates an error and is easily distinguished from an actual result (often null in Javascript) or you can throw … Read more
Actually, the best way to learn about std::expected is a funny talk by the (in)famous Andrei Alexandrescu: “Expect the Expected!” What std::expected is, and when it’s used Here are three complementing explanations of what an std::expected<T, E> is: It is the return type of a function which is supposed to return a T value – … Read more
I think the solution to add following to .psqlrc is far from perfection \set ON_ERROR_STOP on there exists much more simple and convenient way – use psql with parameter: psql -v ON_ERROR_STOP=1 better to use also -X parameter turning off .psqlrc file usage. Works perfectly for me p.s. the solution found in great post from … Read more
For historical reasons these window.onerror is a bit of a special case. Most of these are defunct now, I think you have to back to IE8 to find a browser that needed them. A decade or so ago IE6 was king and it didn’t have support for addEventListener at all, and many events were only … Read more
This happens all the time, if something can not be duplicated by the structured clone algorithm. This algorithm is used by window.postMessage. If we read the documentation from window.postMessage for the first parameter: message Data to be sent to the other window. The data is serialized using the structured clone algorithm. and then open the … Read more
It is a server error, not a client error. If server errors weren’t to be returned to the client, there wouldn’t have been created an entire status code class for them (i.e. 5xx). You can’t hide the fact that you either made a programming error or some service you rely on is unavailable, and that … Read more
Rule of Thumb Whenever you have a doubt about how to do something with promises – think about the synchronous version. try{ var result = myFn(param); // business logic with result } catch(e) { //error handling logic } This, at least to me looks a lot cleaner than a callback with a first parameter that … Read more
