javascript - 如何在某些情况下禁用 wicket 的 setRequired

Question

我对 wicket 还很陌生，刚刚遇到 setRequired。

我有 5 个文本字段

    final TextField<String> mfnField = new TextField<>("mfn",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getMfn()));
        form.add(mfnField);
        mfnField.setOutputMarkupId(true);
        form.add(new FdsInfoButton("mfn.infoButton", new ResourceModel("mfn.infoButton")));
        form.add(new FormComponentFeedbackPanel("mfnFeedbackPanel", mfnField));

final TextField<String> pbField = new TextField<>("pid",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getPBId()));
        form.add(pbField);
        pbField.setOutputMarkupId(true);
        form.add(new FormComponentFeedbackPanel("pidFeedbackPanel", pbField));

        final TextField<String> gpidField = new TextField<>("gpid",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getGpid()));
        form.add(gpidField);
        gpidField.setOutputMarkupId(true);
        form.add(new FormComponentFeedbackPanel("gpidFeedbackPanel", gpidField));

        final TextField<String> tidField = new TextField<>("tid",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getTransaction_id()));
        form.add(tidField);
        form.add(new FdsInfoButton("tid.infoButton", new ResourceModel("tid.infoButton")));
        form.add(new FormComponentFeedbackPanel("tidFeedbackPanel", tidField));
final TextField<String> ibanField = new TextField<>("iban",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getIban()));
        form.add(ibanField);
        ibanField.setOutputMarkupId(true);
        form.add(new FormComponentFeedbackPanel("ibanFeedbackPanel", ibanField));   

我有一个 fromfield 和一个 tofield:

final DateTimePicker fromInput = new DateTimePicker("from",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getFromDate()),
                DateTimePicker.START_OF_DAY);
        form.add(fromInput);
        form.add(new FormComponentFeedbackPanel("fromFeedbackPanel", fromInput));

        final DateTimePicker toInput = new DateTimePicker("to",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getToDate()),
                DateTimePicker.END_OF_DAY);
        form.add(toInput);
        form.add(new FormComponentFeedbackPanel("toFeedbackPanel", toInput));

5 个文本字段中:

• 如果在前四个中输入了任何内容，那么我还需要输入 fromfield 和 tofield，因此对于此 setRequired 应该为 true
• 但如果 tidField 中输入了任何内容，无论其他文本字段是空还是已填充，setRequired 对于 frominput 和 toinput 都应该为 false。

我的问题是如何设置 true 和 false。

或者除了 setRequired 之外我还可以使用其他东西吗？

我找到了解决办法:我必须使用 isRequired 而不是 setRequired

final DateTimePicker fromInput = new DateTimePicker("from",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getFromDate()),
                DateTimePicker.START_OF_DAY) {
            /**
             *
             */
            private static final long serialVersionUID = 1L;

            @Override
            public boolean isRequired() {
                return Strings.isBlank(tidField.getConvertedInput());
            }

        };
        form.add(fromInput);
        form.add(new FormComponentFeedbackPanel("fromFeedbackPanel", fromInput));

        final DateTimePicker toInput = new DateTimePicker("to",
                model(criteriaModel, on(RechercheServiceFunctionCriteria.class).getToDate()),
                DateTimePicker.END_OF_DAY) {

            /**
                     *
                     */
            private static final long serialVersionUID = 1L;

            @Override
            public boolean isRequired() {
                return Strings.isBlank(tidField.getConvertedInput());
            }
        };
        form.add(toInput);
