calling .focus() on <input type=“text”> in WKWebView causes keyboard lag

Question

I'm building an app in HTML5 and Javascript using WKWebView.

I have a very plain text input that I want to call focus() on manually via javascript. It does work, the keyboard pops up and there is a cursor in the input however the iOS keyboard is very laggy when typing/deleting the first character. It takes over a second for the character to appear and for the keyboard to become interactive again.

Does anyone have any idea on how what the problem might be?

Answer 1

Try using click() instead of focus(). Both will give you the same response provided u dont have any events attached to onclick of the text box.

Answer 2

我们在带有WKWebview的AngularJS应用程序中遇到了类似的问题，我们通过使用ng-click事件而不是ng-focus解决了此问题（仅在iOS上）。
