How to manually show tab loading indicator via javascript?

由 牧云@^-^@ 提交于 2020-06-28 11:18:23
问题 I'm talking about an icon that is displayed on a tab during page loading. Chrome: Firefox (with TreeTab plugin): You get the idea. I want to make it seem like the page is loading, when it's already loaded. Some event fires is javascript and then the tab looks like it's being loaded. Is there a way to do that? One way I can think of is to replace a favicon with a spinner, but I'm not sure if it's possible to change on the fly and even if it is, it would be a hassle to make it cross-browser.

问题 How to display validation error for a spinner widget similar to TextView.setError() I don't want to open a new dialog box for every spinner validation error, android.widget.Spinner class doesn’t have setError method 回答1: If your spinner is set-up with default item views the getSelectedView() method on Spinner class will return a TextView .

golang动画等待计算菲波那契结果

一个小玩意，main goroutine将计算菲波那契数列的第45个元素值。由于计算函数使用低效的递归，所以会运行相当长时间，在此期间我们想让用户看到一个可见的标识来表明程序依然在正常运行，所以来做一个动画的小图标： package main import ( "fmt" "time" ) func main() { go spinner(100 * time.Millisecond) const n = 45 fibN := fib(n) // slow fmt.Printf("\rFibonacci(%d) = %d\n", n, fibN) } func spinner(delay time.Duration) { for { for _, r := range `-\|/` { fmt.Printf("\r%c Caculating...", r) time.Sleep(delay) } } } func fib(x int) int { if x < 2 { return x } return fib(x-1) + fib(x-2) } 来源： https://www.cnblogs.com/janeysj/p/12530702.html
