ionic - Copy/paste in input field in iOS 10 not working
Instead of just typing user-select: auto !important;
As in this answer try adding all css to the element instead of just that empty line that might not work on all browsers.
Here:
-webkit-user-select: auto !important;
-khtml-user-select: auto !important;
-moz-user-select: auto !important;
-ms-user-select: auto !important;
-o-user-select: auto !important;
user-select: auto !important;
I was not able to understand your problem.
But if you want it to be really working, you can try it.
Install cordova-plugin-clipboard
var text = "Hello World!";
cordova.plugins.clipboard.copy(text);
cordova.plugins.clipboard.paste(function (text) { alert(text); });
