天氣代碼高級(jí)使用方法：   如果您會(huì)HTML語(yǔ)言，您還可以在iframe代碼中的url后面加參數(shù)，如： chengshi_321.html?c0=F9DC68&c1=white&c2=FEFCE0&t1=red&bg=white&w=178&h=250&text=no   其中 c0 表示 表格第一行背景顏色，c1，c2表示表格其他行間隔的背景顏色，t1表示 標(biāo)題顏色，bg 表示頁(yè)面北京顏色，w表示表格寬度 h 表示表格高度   當(dāng) text=yes 時(shí)，將會(huì)出現(xiàn)滾動(dòng)的天氣文字，建議您自己調(diào)試看看，如： chengshi_321.html??c0=red&c1=FF9900&bg=F4FFF4&w=178&h=20&text=yes   注意：顏色請(qǐng)不要加 # 符號(hào)，如 #FF9900 請(qǐng)寫成 FF9900

說(shuō)明：這種適合于在網(wǎng)頁(yè)的邊欄插入。但一個(gè)缺點(diǎn)是，上面的4個(gè)城市是既定的，無(wú)法改成別的。插 入時(shí)，選好網(wǎng)頁(yè)上的位置，直接將左欄的源代碼全部拷進(jìn)去就行了

說(shuō)明：這種也適合于在網(wǎng)頁(yè)的邊欄插入。上面的城市可以自定，比如廈門可改成別的。定制的方法是修改我代碼中標(biāo)紅的數(shù)字，從1開(kāi)始代表“香港”開(kāi)始，每個(gè)數(shù)字都代表一個(gè)城市，廈門是287，具體要哪個(gè)城市自己找一下罷。

自己從網(wǎng)頁(yè)中偷取天氣數(shù)據(jù)
主要用到Pattern類和Matcher類在java.util.regex.包下面。
首先在網(wǎng)頁(yè)上取得所有數(shù)據(jù)
HttpURLConnection conn = null;
        String outstr = "";
 try {
            String strUrl = "http://www.wopos.com/MainSet/WeatherSet.aspx?city="+address;
            URL url = new URL(strUrl);
            conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.
                    getInputStream(), "GBK"));
            String line = "";
            while ((line = br.readLine()) != null) {
                outstr = outstr + line;
            }
            br.close();
        } catch (Exception ex) {
            ex.printStackTrace(System.out);
        } finally {
            if (conn != null) {
                conn.disconnect();
            }
        }
然后分析數(shù)據(jù)
try{
            Pattern p = Pattern.compile("<span id=\"Label\\d\" style=\"display:inline-block;\"><font size=\"\\d\">[\u4e00-\u9fa5]*\\d*[℃]*[~]*[．]*[-]*\\d*[℃]*[-]*\\d*[．]*\\d*[：]*[\u4e00-\u9fa5]*</font></span>");
            Matcher m = p.matcher(outstr);
            while (m.find()) {
                String s = m.group();
//                System.out.println("s=" + s);
                if(s!=null){
                    hm.put(s.substring(10, 16), s);
                }
            }
        }catch(Exception ex){
            ex.printStackTrace(System.out);
        }
