這篇文章主要介紹“怎么解決Ajax提交參數(shù)的值中帶有html標(biāo)簽不能提交成功的問(wèn)題”,在日常操作中,相信很多人在怎么解決Ajax提交參數(shù)的值中帶有html標(biāo)簽不能提交成功的問(wèn)題問(wèn)題上存在疑惑,小編查閱了各式資料,整理出簡(jiǎn)單好用的操作方法,希望對(duì)大家解答”怎么解決Ajax提交參數(shù)的值中帶有html標(biāo)簽不能提交成功的問(wèn)題”的疑惑有所幫助!接下來(lái),請(qǐng)跟著小編一起來(lái)學(xué)習(xí)吧!
解決辦法如下:
1、在頁(yè)面用JS的Base64編碼(類似加密)帶有html標(biāo)簽的參數(shù)值。
2、在目標(biāo)地址獲取到數(shù)據(jù)后,利用后臺(tái)Base64解碼方法對(duì)獲取到的數(shù)據(jù)進(jìn)行解碼即可。
以下是我的JS的Base64編碼和解碼方法代碼:
//下面是64個(gè)基本的編碼 var base64EncodeChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"; var base64DecodeChars = new Array( -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 62, -1, -1, -1, 63, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, -1, -1, -1, -1, -1, -1, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, -1, -1, -1, -1, -1, -1, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, -1, -1, -1, -1, -1); //編碼的方法 function base64encode(str) { var out, i, len; var c1, c2, c3; len = str.length; i = 0; out = ""; while(i < len) { c1 = str.charCodeAt(i++) & 0xff; if(i == len) { out += base64EncodeChars.charAt(c1 >> 2); out += base64EncodeChars.charAt((c1 & 0x3) << 4); out += "=="; break; } c2 = str.charCodeAt(i++); if(i == len) { out += base64EncodeChars.charAt(c1 >> 2); out += base64EncodeChars.charAt(((c1 & 0x3)<< 4) | ((c2 & 0xF0) >> 4)); out += base64EncodeChars.charAt((c2 & 0xF) << 2); out += "="; break; } c3 = str.charCodeAt(i++); out += base64EncodeChars.charAt(c1 >> 2); out += base64EncodeChars.charAt(((c1 & 0x3)<< 4) | ((c2 & 0xF0) >> 4)); out += base64EncodeChars.charAt(((c2 & 0xF) << 2) | ((c3 & 0xC0) >>6)); out += base64EncodeChars.charAt(c3 & 0x3F); } return out; } //解碼的方法 function base64decode(str) { var c1, c2, c3, c4; var i, len, out; len = str.length; i = 0; out = ""; while(i < len) { do { c1 = base64DecodeChars[str.charCodeAt(i++) & 0xff]; } while(i < len && c1 == -1); if(c1 == -1) break; do { c2 = base64DecodeChars[str.charCodeAt(i++) & 0xff]; } while(i < len && c2 == -1); if(c2 == -1) break; out += String.fromCharCode((c1 << 2) | ((c2 & 0x30) >> 4)); do { c3 = str.charCodeAt(i++) & 0xff; if(c3 == 61) return out; c3 = base64DecodeChars[c3]; } while(i < len && c3 == -1); if(c3 == -1) break; out += String.fromCharCode(((c2 & 0XF) << 4) | ((c3 & 0x3C) >> 2)); do { c4 = str.charCodeAt(i++) & 0xff; if(c4 == 61) return out; c4 = base64DecodeChars[c4]; } while(i < len && c4 == -1); if(c4 == -1) break; out += String.fromCharCode(((c3 & 0x03) << 6) | c4); } return out; } function utf16to8(str) { var out, i, len, c; out = ""; len = str.length; for(i = 0; i < len; i++) { c = str.charCodeAt(i); if ((c >= 0x0001) && (c <= 0x007F)) { out += str.charAt(i); } else if (c > 0x07FF) { out += String.fromCharCode(0xE0 | ((c >> 12) & 0x0F)); out += String.fromCharCode(0x80 | ((c >> 6) & 0x3F)); out += String.fromCharCode(0x80 | ((c >> 0) & 0x3F)); } else { out += String.fromCharCode(0xC0 | ((c >> 6) & 0x1F)); out += String.fromCharCode(0x80 | ((c >> 0) & 0x3F)); } } return out; } function utf8to16(str) { var out, i, len, c; var char2, char3; out = ""; len = str.length; i = 0; while(i < len) { c = str.charCodeAt(i++); switch(c >> 4) { case 0: case 1: case 2: case 3: case 4: case 5: case 6: case 7: // 0xxxxxxx out += str.charAt(i-1); break; case 12: case 13: // 110x xxxx 10xx xxxx char2 = str.charCodeAt(i++); out += String.fromCharCode(((c & 0x1F) << 6) | (char2 & 0x3F)); break; case 14: // 1110 xxxx 10xx xxxx 10xx xxxx char2 = str.charCodeAt(i++); char3 = str.charCodeAt(i++); out += String.fromCharCode(((c & 0x0F) << 12) | ((char2 & 0x3F) << 6) | ((char3 & 0x3F) << 0)); break; } } return out; }
頁(yè)面調(diào)用JS方法進(jìn)行Base64編碼代碼如下:
var articleContent = editor.getContent(); articleContent = base64encode(utf16to8(articleContent));
但是呢,又遇到一個(gè)新的問(wèn)題,用JS對(duì)數(shù)據(jù)進(jìn)行Base64編碼后,JS居然把加號(hào)(+)替換成了空格,造成我后臺(tái)方法解碼出來(lái)的數(shù)據(jù)不正確。
解決辦法如下:
本人首先采用JS方法replace()方法進(jìn)行替換,但是有錯(cuò)誤,JS只是把我的第一個(gè)空格替換成了加號(hào)(+),最后解決辦法如下。
在后臺(tái)(目標(biāo)接受地址下)對(duì)獲取到的數(shù)據(jù),把空格替換成加號(hào)(+)。代碼如下:
string content = Request["content"].ToString(); if (content.Contains("")) { content=content.Replace(" ", "+"); } //byte[] sa = Convert.FromBase64String(content); //Encoding Ansi = Encoding.GetEncoding("GB2312"); // content = Ansi.GetString(sa); content = Base64Decrypt(content);//Base64解碼
如果后臺(tái)的Base64編碼和解碼方法不會(huì)的請(qǐng)看下面:
////// Base64加密 /// /// 需要加密的字符串 ///public static string Base64Encrypt(string input) { return Base64Encrypt(input, new UTF8Encoding()); } /// /// Base64加密 /// /// 需要加密的字符串 /// 字符編碼 ///public static string Base64Encrypt(string input, Encoding encode) { return Convert.ToBase64String(encode.GetBytes(input)); } /// /// Base64解密 /// /// 需要解密的字符串 ///public static string Base64Decrypt(string input) { return Base64Decrypt(input, new UTF8Encoding()); } /// /// Base64解密 /// /// 需要解密的字符串 /// 字符的編碼 ///public static string Base64Decrypt(string input, Encoding encode) { return encode.GetString(Convert.FromBase64String(input)); }
