Question

我有两种形式。形式＆＃34; form2＆＃34;有几个按钮。当按下其中一个按钮时，我想按下表格中的隐藏按钮＆＃34; form1＆＃34;提交并更新整个表格。

但是当我按下我的表单2中的按钮时，我仍然遇到问题，未提交值。是javascript函数错误还是让Primefaces / JSF更好地做到这一点？

我使用的是Primefaces 5。

        actionListener="#{myBean.doSomeBackendStuff()}"

我的豆子：

package de.vwag.flucs.presentation.admin.boundary;

import java.io.Serializable;

import javax.inject.Named;

import org.apache.myfaces.extensions.cdi.core.api.scope.conversation.ViewAccessScoped;

@ViewAccessScoped
@Named("myBean")
public class MyBean implements Serializable {

    private static final long serialVersionUID = -8923580640140500834L;

    private String myTestInputText = "";

    public String getMyTestInputText() {
        return myTestInputText;
    }

    public void setMyTestInputText(String myTestInputText) {
        this.myTestInputText = myTestInputText;
    }

    public void doSomeBackendStuff() {
        // Do Some Backendstuff!
        System.out.println("He hit me! He entered: " + myTestInputText );
    }
}

Answer 1

基本上javascript不起作用，因为隐藏按钮的客户端ID不是myHiddenButton它应该是form1:myHiddenButton

jsf通过javascript从另一个表单按下隐藏的按钮
