这是我的托管bean方法：

 public void getjs(){
              FacesContext context = FacesContext.getCurrentInstance();
              Map<String, String> map = context.getExternalContext().getRequestParameterMap();
              String value = (String) map.get("param");
              System.out.println("**************** ***************** " + value);
            }

直到$（＆＃34; #myForm \：grand_Total＆＃34;）。val（val3 * val4 / 100）;在我的xhtml页面工作但命令（[{name：＆＃39; param＆＃39;，value：val3}]）;不工作问题如何将值传递给托管bean p：remoteCommand getjs方法没有得到param的值请建议我这样做的方法

将参数传递给p：remoteCommand到支持bean方法并在页面提交之前获取结果
