If textbox input between 0 and 1
显示 更早的评论
I am trying to check the value a user enters into a textbox in the App Designer interface. The value the user inputs must be between 0 and 1.
value = app.EditField.Value;
if (value >= 0 && value <=1)
% call function
else
msgbox("Value must be a value between 0 and 1.");
end
This is not working correctly. For example, if I enter 0 or 1, it outputs the message. If I input a value between 0 and 1 I get this error:
Operands to the || and && operators must be convertible to logical scalar values.
How can I fix this? Thank you.

In the component browser, consider changing the limits property of the NUMERIC edit field to 0,1. That way you can just have your callback call the function without having to check.

I suspect the edit field is outputing text.

Just use Edit Field (Numeric) instead of Edit Field (Text) from the Component Library.
You can also confirm Edit field property in App initialization and construction section
app.EditField = uieditfield(app.xxx,'text');
I tried and its working for me.
