以编程方式折叠或展开p：accordionPanel

标签： primefaces jsf-2.2

我想要实现的目标是什么？

单击加载按钮后，如果设置了任何一个文本字段，那么结果“手风琴面板”过滤器应该展开。
点击加载按钮后，如果未设置所有文本字段，那么“手风琴面板”过滤器应该会崩溃。

我已经通过手风琴面板primefaces文档，但无法发现它有用。 http://www.primefaces.org/docs/vdl/3.5/primefaces-p/accordionPanel.html

我已经完成了之前在stackoverflow上提出的问题，这个问题的答案也无法让我满足我的要求。

ManagedBean


    package com.pk.test;

    import javax.faces.bean.ManagedBean;

    @ManagedBean(name="testBean")
    public class AccordionTestBean {

        private String name;

        private String semester;

        private String age;

        private Boolean checkNameTextField = false;

        public void save(){
            System.out.println("Close Filter If any one field of form is set");
            System.out.println("Name: "+getName());
            System.out.println("Age: "+getAge());
            System.out.println("Semester: "+getSemester());
            if(getName()!= null){
                setCheckNameTextField(true);
    //if name textfield is set to a value, on save click filter will not collapse or close
            }
            else
                setCheckNameTextField(false);
    //if name textfield is set to a value, on save click filter will collapse

        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getSemester() {
            return semester;
        }

        public void setSemester(String semester) {
            this.semester = semester;
        }

        public String getAge() {
            return age;
        }

        public void setAge(String age) {
            this.age = age;
        }

        public Boolean getCheckNameTextField() {
            return checkNameTextField;
        }

        public void setCheckNameTextField(Boolean checkNameTextField) {
            this.checkNameTextField = checkNameTextField;
        }
    }

我确实理解你要做的是什么，但是为了扩展/缩小手风琴面板，你可以使用这个

展开：PF('accordian-widgetVar').select(index)

崩溃：PF('accordian-widgetVar').unselect(index)

其中accordian-widgetVar是您的accordionPanel的属性widgetVar的值，index是您要展开/折叠的标签的索引

你也可以从像这样的bean执行它 RequestContext.getCurrentInstance().execute("PF('accordian-widgetVar').unselect(index)");
