Question

我正在研究Java项目。我想修改html代码以在java类中显示一些额外的变量。其中之一是静态整数。

Java类代码：

public class AuctionContext {
public static enum AuctionType {SAA, CCA, LUA};
private AuctionType type;
private int round;
private int duration_ms;
private ArrayList<AuctionItem> itemList;
private double minIncreament;
//priceTick is used in CCA and LUA auction, keep track of current 
    price for all items.

private double priceTick = 0;
private boolean finalRound;
public static int numberOfActivityRuleWaivers = 2;
private boolean activityRuleAnnounced = false;
private int activityRuleStartRound = -1;
private int test=15;
private int summElig;

变量numberOfActivityRuleWaivers是我要在html页面中显示的内容。

xml中写入静态变量的部分：

child = doc.createElement("waivers");
child.setAttribute("value", Integer.toString(numberOfActivityRuleWaivers));
root.appendChild(child);

html代码（其中显示双括号和放弃的部分）：

<polymer-element name="auction-saa">
<template>
<link rel="stylesheet" href="./auction-saa.css" type="text/css" />

<div id="auction-saa">
  <div class="title">
    <p>SAA - <span>Round {{ round }}</span></p>
  </div>
  <div id="box">
    <p id="time"></p>
<p id="timeduration"> Minimum Increment: {{ minimumIncreament }} </p>
<p id="waivers"> Number of Waivers {{waivers}}</p>
<p id="warning"></p>
<p id="activityruleannouncement"></p>
<p id="leadingitems"></p>
<p id="activityandeligibility"></p>

和javascript（我将其初始化并稍后在函数中构建）：

Polymer('auction-saa', {
 waivers:-1,
 test:-1,

displaywaivers:function()
 {   this.summElig = this.saa.summElig;

 },

我在大括号和xml的值中使用了相同的词。当我运行此代码时，html显示0，但实际数字应为2。任何非静态字段都正确显示。你能帮我吗？

通过JavaScript将静态int字段显示为html
