用Javascript实现UTF8编码转换成gb2312编码

答案：
复制代码 代码如下:
//把编码转换成 gb2312编码  
function UrlEncode(str)  
{  
var i, c, ret="", strSpecial="!\"#$%&'()*+,/:;<=>?@[\]^`{|}~%";  
for(i = 0; i < str.length; i++)  
{  
//alert(str.charCodeAt(i));  

c = str.charAt(i);  
if(c==" ")  
ret+="+";  
else if(strSpecial.indexOf(c)!=-1)  
ret += "%" + str.charCodeAt(i).toString(16);  
if(z[str.charCodeAt(i)]　!= null)  
{  
d = z[str.charCodeAt(i)];  
try  
{  
ret += "%" + d.slice(0,2) + "%" + d.slice(-2);  
}  
catch (e)  
{  
alert(" $$ error name = " + e.name + ", message = " +e.message + ", d " + i + "= " + str.charCodeAt(i))  
}  
}  
else  
ret += c;  
}  
return ret;  
}  

function getSpell(str, sp)  
{  
var i, c, t, ret="";  
if(sp == null)  
sp="";  

for(i = 0; i < str.length; i++)  
{  
if(str.charCodeAt(i) >= 0x4e00)  
{  
c = parseInt(z[str.charCodeAt(i)], 16);  
if(c < 55290)  
{  
for(t = qswhSpell.length-1; t > 0; t = t - 2)  
if(qswhSpell[t] <= c)  
break;  
if(t > 0)  
ret += qswhSpell[t - 1] + sp;  
}  
}  
}  
return ret.substr(0, ret.length-sp.length);  
}
