Your problem may be happening because you are assigning the same handler to the click event multiple times. I suggest you check that the line where you assign the handler is not being called multiple times inadvertently. Another solution could be a call to unbind (deprecated 3.0) or off (superseeded) first: $(“#myButton”).unbind(“click”).click(myHandler); // deprecated $(“#myButton”).off(“click”).click(myHandler); … Read more
I can’t find a suitable event for that. Yeah, there isn’t one. There are DOM Mutation Events, but they aren’t supported well cross-browser, and don’t fire for form values anyway as those aren’t reflected in attributes (except in IE due to a bug). In Mozilla only, a JavaScript watch could be set on the value … Read more
No, and if there was it would be browser dependent. What kind of code are you trying to run when the user closes the page? Is it to logout the user? Then the user would not be logged out if the browser crashes or the network connection breaks (and probably not if the computer goes … Read more
It’s simply not possible to get the onKeyUp events when meta is used, I learned today. Very unfortunate and difficult to work around. You’ll have to emulate them some other way. Edit: To clarify, this is only on Mac and occurs due to OS level handling of the event. It cannot be overridden. Sorry to … Read more
Ok, so what I found is that you can make UDF functions in mysql that can do anything but need to be written in C/C++. They can be then called from triggers on updates in database and notify your application when update happened. I saw that there are some security concerns. I did not use … Read more
In CellContentDoubleClick event fires only when double clicking on cell’s content. I used this and works: private void dgvUserList_CellDoubleClick(object sender, DataGridViewCellEventArgs e) { MessageBox.Show(e.RowIndex.ToString()); }
But keep in mind that addEventListener is supported in IE just from version 9. To support older versions of IE you could use something like that: if (element1.addEventListener) { // all browsers except IE before version 9 element1.addEventListener(“click”, CalCal, false); } else { if (element1.attachEvent) { // IE before version 9 element1.attachEvent(“click”, CalCal); } }
If the BackgroundWorker was created from the UI thread, then the RunWorkerCompleted event will also be raised on the UI thread. If it was created from a background thread, the event will be raised on an undefined background thread (not necessarily the same thread, unless you’re using a custom SynchronizationContext). Interestingly, this doesn’t seem to … Read more
Use SHOW VARIABLES SHOW VARIABLES WHERE VARIABLE_NAME = ‘event_scheduler’
The following worked for me: import userEvent from “@testing-library/user-event”; import { render } from “@testing-library/react”; test(“should submit when pressing enter”, () => { const handleSubmit = jest.fn(); const { getByLabelText } = render(<App handleSubmit={handleSubmit} />); const input = getByLabelText(“Name:”); userEvent.type(input, “abc{enter}”); expect(handleSubmit).toHaveBeenCalled(); });
