I want to hide the keyboard on Focus(),but when $(".ui-input-text").focus(); it will automatically open the keyboard .
I just want to hide in particular screen ,I have test with document.activeElement.blur();
but it also did not focus() on input .
When submitting a form, at times, the iOS Keyboard may not automatically close. This is quite a usability issue as Users should not be required to manually close the Keyboard for use-cases in which they would otherwise not expect the need do so.
A simple solution for this can be implemented by invoking the blur method on document.activeElement, which effectively allows one to programmatically hide the keyboard:
// automatically close the keyboard on iOS
document.activeElement.blur();
