JavascriptUrlDecode函数代码_javascript技巧

代码
代码如下:
/**
* Url编码
**/
ShengUtils.encode = function(unzipStr){
var zipstr="";
var strSpecial="!\"#$%&'()*+,/:;<=>?[]^`{|}~%";
var tt= "";
for(var i=0;ivar chr = unzipStr.charAt(i);
var c=ShengUtils.StringToAscii(chr);
tt += chr+":"+c+"n";
if(parseInt("0x"+c) > 0x7f){
zipstr+=encodeURI(unzipStr.substr(i,1));
}else{
if(chr==" ")
zipstr+="+";
else if(strSpecial.indexOf(chr)!=-1)
zipstr+="%"+c.toString(16);
else
zipstr+=chr;
}
}
return zipstr;
}

/**
* Url解码
**/
ShengUtils.decode=function(zipStr){
var uzipStr="";
for(var i=0;ivar chr = zipStr.charAt(i);
if(chr == "+"){
uzipStr+=" ";
}else if(chr=="%"){
var asc = zipStr.substring(i+1,i+3);
if(parseInt("0x"+asc)>0x7f){
uzipStr+=decodeURI("%"+asc.toString()+zipStr.substring(i+3,i+9).toString()); ;
i+=8;
}else{
uzipStr+=ShengUtils.AsciiToString(parseInt("0x"+asc));
i+=2;
}
}else{
uzipStr+= chr;
}
}
return uzipStr;
}

ShengUtils.StringToAscii=function(str){
return str.charCodeAt(0).toString(16);
}

ShengUtils.AsciiToString = function(asccode){
return String.fromCharCode(asccode);
}
