javascript 8进制十六进制转十进制,请大神看看哪里错了

缺少十六进制数字 - JavaScript当前位置:& &&&js错误
缺少十六进制数字js错误

缺少十六进制数字
原因是JS提交数据时出现特殊符号
JS提交数据时出现特殊符号"\",javascript中"\"是个特殊的字符,在很多场合需要转换。
例子程序:
*Encode for HTML.
public static String htmlEncoder(String str)
if(str==null || str.equals(""))
return "";
String res_
res_str=strReplace(str,"&","&");
res_str=strReplace(str," ","&");
res_str=strReplace(str,"&","&");
res_str=strReplace(str,"&","&");
res_str=strReplace(str,"\"","&");
res_str=strReplace(str,"'","'");
return res_
*Encode for HTML-Text.
public static String htmlTextEncoder(String str)
if(str==null || str.equals(""))
return "";
String res_
res_str=strReplace(str,"&","&");
res_str=strReplace(str,"&","&");
res_str=strReplace(str,"&","&");
res_str=strReplace(str,"\"","&");
res_str=strReplace(str,"'","'");
res_str=strReplace(str," ","&");
res_str=strReplace(str,"\r\n","&br/&");
res_str=strReplace(str,"\r","&br/&");
res_str=strReplace(str,"\n","&br/&");
return res_
*Encode for URL.
public static String urlEncoder(String str) {
return java.net.URLEncoder.encode(str) ;
*Encode for XML.
public static String xmlEncoder(String str)
if(str==null || str.equals(""))
return "";
String res_
res_str=strReplace(str,"&","&");
res_str=strReplace(res_str,"&","&");
res_str=strReplace(res_str,"&","&");
res_str=strReplace(res_str,"\"", "&");
res_str=strReplace(res_str,"\'", "&");
return res_
*Encode for SQL.
public static String sqlEncoder(String str)
if(str==null || str.equals(""))
return "";
String res_
res_str=strReplace(str,"'","''");
return res_
*Encode for Javascript.
public static String jsEncoder(String str)
if(str==null || str.equals(""))
return "";
String res_
res_str=strReplace(str,"'","");
res_str=strReplace(str,"\"",""");
res_str=strReplace(str,"\r\n","");
res_str=strReplace(str,"\n","");
res_str=strReplace(str,"\r","");
return res_
html=html+replace(table_list(fileExt,path,2),"\","/")+""""

比如传入字符串“aa”转换出应该是170,可是转化出来确是,请问哪里有问题?请针对问题回答

提问者采纳
break.pow(16;
return HTDS
case &quot,算法设计问题;, index) * 8, index) * 5;
a&index对应进制值
var HTDSult = 0;
9&.pow(16;,满足
index++:&quot, index) * 3.pow(16;1&quot, index) * 7:
HTDSult = HTDSult + Math:
HTDSult = HTDSult + Math, index - 1) * 14:
HTDSult = HTDSult + M;
var strLen = FormatS
case &quot, 1)) {
case &quot。其次;
case &quot首先:aaaa = 16的3次方 x 10 + 16的2次方 x 10 + 16的1次方 x 10 + 16的0次方 x 10;,进制转换;;;&#47:
HTDSult = HTDSult + Math:
HTDSult = HTDSult + M
case &quot.pow(16.pow(16:
HTDSult = HTDSult + Math, index) * 12:
HTDSult = HTDSult + Math:
HTDSult = HTDSult + M.pow(16, index) * 11;;;
case &quot.substr(strLen-index -1:
HTDSult = HTDSult + M从最低位取值
var HexBit = 1;f&
case &quot, index) * 4:
HTDSult = HTDSult + Math, index) * 0, index - 1) * 13;;6&
b&quot。function HexToDec(inStr) {
var FormatStr = inS4&
break.pow(16,可以参考;
case &quot, index) * 9.pow(16.如下根据你的代码改过:
HTDSult = HTDSult + Ma&quot.pow(16;3&
HTDSult = HTDSult + M
case &quot, index) * 1;
HTDSult = HTDSult + M &#47.pow(16;e&quot.pow(16;5&;
break.pow(16, index) * 6;
while (index &0&quot,后面的case也会继续执行;后.pow(16;:
HTDSult = HTDSult + Math,直到遇到break, index) * 10;d&
var index = 0.pow(16;
case &c&quot:
HTDSult = HTDSult + Math,每一个case都要以break结束(除非特殊需要);
break:比如;8&quot.toLowerCase();
case &quot.pow(16;2&,否则, index) * 2:
HTDSult = HTDSult + Math,从高位开始计算需要得到对应的(幂值),switch语句用错了;
switch (FormatStr, index - 1) * 15.pow(16
