javascript : escape 編碼與C# 的使用問題.

οnsubmit="form1.Text1.value?=?escape(form1.Text1.value);"

?

?

.cs處理?

?

?string?a?=?HttpUtility.UrlDecode(Text1.Value);
Response.Write(a);

?

?

//c#實(shí)現(xiàn)escape編碼：（用在ajax中）然后在aspx用unescape解碼，就不會出現(xiàn)亂碼問題
?private?string?escape(string?s)
????{
????????StringBuilder?sb?=?new?StringBuilder();
????????byte[]?ba?=?System.Text.Encoding.Unicode.GetBytes(s);
????????for?(int?i?=?0;?i?<?ba.Length;?i?+=?2)
????????{???
????????????sb.Append("%u");
????????????sb.Append(ba[i?+?1].ToString("X2"));

????????????sb.Append(ba[i].ToString("X2"));
????????}
????????return?sb.ToString();

????}??

另外一些方法 ---------------------------- encodeURIComponent() /?decodeURIComponent() encodeURI()/decodeURI() 注意上面兩對javascript函數(shù)使用的編碼多是utf-8 應(yīng)次如果頁面使用編碼不是utf-8就需要做另外的處理 asp.net 發(fā)數(shù)據(jù)給 javascript 在頁面使用gb2312時 encodeString=HttpUtility.UrlEncode("中問是中問http://www.gyzs.net/", System.Text.Encoding.UTF8) 接收 <script>document.write(decodeURIComponent('<%=encodeString %>'));</script> javascritp 發(fā)數(shù)據(jù)給asp.net 頁面中有如下js腳本 <script>document.write("<a href='?t=" +encodeURI('中問是中問http://www.gyzs.net') +"' >點(diǎn)我</a>");</script> 如果web.config中配置使用gb2312那么就要做如下處理 ?Response.Write(HttpUtility.UrlDecode( Server.UrlEncode( Request["t"]),System.Text.Encoding.UTF8)); 如果web.config中使用的utf-8那么直接使用Request["t"]就可以 另外要注意表單提交使用post方法時,會對表單里的數(shù)據(jù)進(jìn)行 url編碼,注意不要重復(fù)
