Javascript 如何禁用wicket设置在某些情况下是必需的

我对维克特是个新手，刚刚遇到过他

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));   

在5个文本字段中：

如果在前四个字段中输入了任何内容，那么我需要同时输入fromfield和tofield，因此对于此设置，Required应该为true 但是，如果在tidField中输入了任何内容，不管其他文本字段是空的还是满的，那么对于frominput和toinput，setRequired应该为false。 我的问题是如何设置正确和错误

或者除了setRequired之外，还有什么我可以使用的吗？

我找到了解决方案： 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);

我只是想改进它的格式，或者帮助人们理解你的问题，并帮助你得到一个合适的答案。但您仍然需要添加进一步的信息才能解决您的问题。在我们有机会回答您之前，您的问题已经结束。看一看IFormValidator类。您需要实现它并将a、b、c、d和e列为依赖项，然后将其添加到表单：myForm.addnew MyFormValidator。这样，您将拥有所有依赖项的值，您可以决定是通过验证还是失败。@martin-g我也尝试过在IFormValidator中进行验证，但每次都会有奇怪的反应，有时会显示错误消息，有时则不会。

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);
