我在 JSF 2.1 中使用 Raphael 图表。我正在尝试绘制一个折线图,它接受 x 轴的输入是一个数组数组,y 轴也是如此。我的 x 轴应该包含时间戳(xhtml 中的 xvals),y 轴应该包含 avgVal(xhtml 中的 avgbpsvals)。如何在 javascript 中访问 TBean 实例变量,如 dt、avgVal?ui:repeat 只给我结果bean。
Class InputBean{
private List<List<TBean>> results;
private List<TBean> result;
private String resultJSON;
//getters and setters
private String getResultJSON(){
Gson gson = new Gson();
return gson.toJson(results);
}
}
Class TBean{
private Timestamp dt;
private Long avgVal;
//getters and setters
}
