提交表单时检索Wicket文本字段的值

Question

Inside a ModalWindow , I have a panel that contains a text field. How can I use Wicket to retrieve the value of the field when the user submits the form that it is a part of?

Answer 1

One common way to save form values is to set up a PropertyModel ( Javadoc ) relationship between the form component (in your case, the text field) and some variable in your Java code.

For example, if you're trying to get the name of a company's CEO, you might use

Company theCompany = new Company();
// ...
add(new TextField("ceoName", new PropertyModel(theCompany, "ceo")));

in your page class,

<input type="text" wicket:id="ceoName">

in your markup and

class Company {
    String ceo;
    // ...

elsewhere.

If you provide more information about what you're trying to do, I and others might be able to provide more specific/helpful answers.
