I'm happy to live!

最近接觸了jquery,感覺很不錯，以后不用寫這么繁雜的js代碼了,不錯,現在手上又接了個新項目,正好在新項目上邊學邊用了,此文繼續更新中...

以下是近期項目碰到的ajax的一些問題列舉出來供大家分享,希望有所幫助,還在不斷增加中:

1.ajax,action中response返回的xml文檔格式錯誤時,eclipse debug進入不到action中.

2.ajax緩存問題,需要加入xmlHttp.setRequestHeader("If-Modified-Since","0");便可解決.

3.如果不是ajax提交,而設置了PrintWriter out = response.getWriter();則jsp會產生中文亂碼.

4.ajax返回xml亂碼的原因
response.setContentType("text/xml;charset=GBK");
PrintWriter out = response.getWriter();
這樣才起作用,如果這樣:
PrintWriter out = response.getWriter();
response.setContentType("text/xml;charset=GBK");
那么response.setContentType("text/xml;charset=GBK");就不起作用了所以返回是亂碼,這個問題搞了很久,代碼還得仔細看啊.

5.ajax表單提交
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
由于傳過去的是utf-8編碼的,所以在action 或servlet中接受時要進行相應轉碼.

The orgznization has developed rapidly.
I thouht how  I can share my achievements with them?

The organization has a community on it's website.
I thought I can learned a lot of knowledge of java  here. 

Up to now,my classmate Tao Wei has not found his purse.
There are 30$,a identity  card and some credit cards in his purse,Mrs Tao was very unhappy.
He wont to remember what he has done the whole day.
I  lost my purse  two months ago,there were 200$ , a identity card and 3 credit cards in my purse.
So,I understood Mrs Tao's feeling now.

I got up and looked out of the window this morning,oh,it rained again.
I had  breakfast and then went to  work.
A lot of people were waiting for the bus at the bus station this morning.
But the traffic was very havey.
We got on the bus after waiting for a long time .
I disliked this weather, because it was very cold.

昨天在網上不經意的在ＢＴ上下了一部俄國戰爭影片《第九突擊隊》,沒想到俄國影片會有如此高的素質，影片一開始就緊緊的把人吸引住了，真有點美國大片的感覺,影片主要講俄國在阿富漢的戰爭，
幾個小伙子從新兵訓練營到阿富漢的戰場，到投入戰斗，真的有點寫實，不排除對美國戰爭片的很多引用，特別是到阿富漢飛機舷窗ＳＨＥＮＧ起來的時候，阿富漢風格的音樂響起，一架武裝直升機在半空中盤弦，更讓人想了ＪＩＥ他們將ＺＡＯ　ＹＵ到怎樣的阿富漢人，怎么樣的戰斗，，把戰爭除開，阿富漢的山地在影片中，我覺得特別的美，，，唉，可惜有基地在那里，現在沒人ＧＡＮ去那里旅游．．．
不過這真是一部值得一看的影片．．

全場比賽,無論是控球時間，有威脅的進攻，阿根廷都處于絕對優勢,里克爾梅真的是一位大師級的中場天才，他的傳球，太歷害了．．
不過，最后五分鐘，，歐文的兩個頭球，讓阿根廷嘗到了失敗的滋味，歐文全場比賽好像就沒露幾個臉，，最后時刻卻給全場觀眾來了兩個驚喜．．不能不說，幾年前的神奇小子又回來了．．．

快終場時，我還以為我的2:1馬上就會成為現實，，可惜歐文又回來了。。唉！

今晚又將上演舉世囑目的英阿大戰(英格蘭 vs 阿根廷),我當然不用說，我是一名阿根廷的絕對擁護者.
雖然QIE爾西在歐洲是大紅大紫,蘭帕德更被ＹＵ為當前歐洲最好的中場球員之一，還有杰拉德也是在去年的冠軍聯賽中大紅大紫,在加上bei帥，和喬科爾等人其中的任何一個，都是世界級的中場搭配.
不過在我看來這個中場在進行攔截上倒是非常有實力的，進攻中有ＢＥＩ帥精準的長傳，也會有一定的效果,蘭帕德和杰拉德都有很強的遠射能力．但是在控制球方面就可能差很多了(相對阿根廷).可能只有喬科爾或賴特.菲利ＰＵ斯還有一定的控帶能力.相比阿根廷隊,中場方面的控制能力就要強很多了，首先是現在佩克爾曼的心腹里克爾梅，他的盤帶能力絕對是世界頂尖級的.然后就是艾馬爾,他也是一位非常有靈氣的中場球員，還有托后一點的索林，他現在絕對是阿根廷隊中的全能型球員，，在中場的控制方面，我看來今晚阿根廷絕對會占很大的優勢.

今晚有一大ＹＩ憾便是不能看到18歲的天才球員梅西,如果他能上的話還可以和英格蘭的天才少年ＬＵ尼來個大火拼...

英格蘭一定會在穩定后防的前提下先ＫＡＯ歐文和ＬＵ尼的速度打反擊，，這也是2002年world cup上打敗阿根廷的方法，，它的防守倒是比阿根廷有實力，，很難能夠滲透進去，，我想必須要有個人英雄主義的發揮才行，不然很困難..

今晚應該是一場非常精彩的比賽..晚上又要ＡＯ夜了...誰叫我喜歡足球呢?
我預測比分 2:1 阿根廷勝
