textfield

问题 could you please show me the solution to make the input text of password field show/hide when clicking another button?!

问题 I'm trying to generate a set of text fields for an array using Rails 2.3. I have an array in my controller (which is not part of the model), and I'd like to make a text field for each entry.

问题 I want to switch 3 views and let them switch from 1-2-3. The first view is to let users input name and password, the second view will show his information to let him confirm and the third view will show him a list of options so he can choose what to do next. The problem is how to switch these views? If I use a navigation controll to switch views, how can I add textfield in it so users can input their infomation? 回答1: Thanks for your answers and I find this isn't so complicated as I thought

问题 If you create a binding between a JavaFX TextField and a property, then this binding is invalidated on every keystroke, which causes a change to the text. If you have a chain of bindings the default behavior could cause problems, because in the middle of the editing values may be not valid.
