It is not required to trigger the event in orther to get back the widget result. You can simply use get_value on python side. So, if you need the value of all the widgets in a form, call get_value for each one. |

Odd. I was struggling with this just yesterday, and resolved it only by adding a
Perhaps I wasn't clear, because I don't want to focus on multiple widgets at once. I just want to be able to invoke focus, period. I guess you're referring to these lines in gui.py (starting at 1435): }else if( received_msg[0]=='1' ){ /*update_widget*/
// ... snip
var elemToFocus = document.getElementById(focusedElement);
if( elemToFocus != null ){
elemToFocus.focus();
try{
elemToFocus = document.getElementById(focusedElement);
if(caretStart>-1 && caretEnd>-1) elemToFocus.setSelectionRange(caretStart, caretEnd);
}catch(e){console.debug(e.message);}
}The functionality I want seems to work when I add the following code to def focus(self, app_instance):
app_instance.execute_javascript(
"""
// need a timeout in case it was previously disabled
setTimeout(() => {
el = document.getElementById('%(id)s');
el.focus();
}, 100)
""" % {"id": self.identifier}
)But I could definitely be missing something. |

I've noticed a few things about some keyboard interaction and text inputs that prompt questions.
Mere curiosity

oninput(I think?) returned more than just thevalue. For backward compatibility, though, I'm not sure this is feasible.request_focus()method that wraps the.focus()method for HTML elements would be very convenient. Consider a document with multipleTextInputs; whenonchangeoccurs in one, the handler could automatically focus on the next one, rather than forcing the user to do that somehow.Sliderwidget is focused, it makes sense to have it respond toonkeydown; I have anExtendedSliderthat uses this to:Beta Was this translation helpful?
