converting strings to gb2312 or utf-8 encoded parameters (JS version) _javascript tips

In many cases, we directly in the URL to pass Chinese parameters, read the Chinese are garbled, then how should we convert these parameters?

Now let's introduce the method.
1, we create a new urlencode.js and then copy the following code into the

Copy Code code as follows:

JS version of the Server.URLEncode encoding function
String.prototype.UrlEncodeGB2312 = function () {
var str = this;
str = str.replace (/./g, function (ShEx) {
Window. Encodestr = "";
Window.shex = ShEx;
Window.execscript (' window. Encodestr=hex (ASC (Window.shex)) ', "VBScript");
return window. Encodestr.replace (/.. /g, "%{blogcontent}amp;");
});
return str;
}
String.prototype.UrlEncode = function () {
var s = Escape (this);
var sa = s.split ("%");
var Retv = "", RetE = "";
if (Sa[0]!= "") {
Retv = sa[0];
}
for (var i = 1; i < sa.length; i++) {
if (sa[i].substring (0, 1) = = "U") {
Retv + = Hex2utf8 (Str2hex (sa[i].substring (1, 5));
if (Sa[i].length > 4)
Retv + + sa[i].substring (5);
}
else Retv + = "%" + sa[i];
}
return RETV;
}
function Str2hex (s) {
var c = "";
var n;
var ss = "0123456789ABCDEF";
var digs = "";
for (var i = 0; i < s.length; i++) {
c = S.charat (i);
n = ss.indexof (c);
Digs + = Dec2dig (eval (n));
}
return digs;
}
function Dec2dig (N1) {
var s = "";
var n2 = 0;
for (var i = 0; i < 4; i++) {
N2 = Math.pow (2, 3–i);
if (N1 >= n2) {
s + + ' 1 ';
N1 = N1–N2;
}
Else
s + + ' 0 ';
}
return s;
}
function Dig2dec (s) {
var Retv = 0;
if (s.length = = 4) {
for (var i = 0; i < 4; i++) {
Retv + = eval (S.charat (i)) * MATH.POW (2, 3–i);
}
return RETV;
}
return-1;
}
function Hex2utf8 (s) {
var RetS = "";
var TempS = "";
var ss = "";
if (s.length = = 16) {
TempS = "1110" + s.substring (0, 4);
TempS + = "Ten" + s.substring (4, 10);
TempS + = "Ten" + s.substring (10, 16);
var sss = "0123456789ABCDEF";
for (var i = 0; i < 3; i++) {
RetS + = "%";
SS = temps.substring (I * 8, (eval (i) + 1) * 8);
RetS + = Sss.charat (Dig2dec (ss.substring (0, 4));
RetS + = Sss.charat (Dig2dec (ss.substring (4, 8));
}
return RetS;
}
Return "";
}

2, the use of the method, of course, is our ((string). UrlEncode ()) can convert a string to a utf-8-encoded URL parameter (string. UrlEncodeGB2312 ()) You can convert the string into gb2312 encoded parameters, well, O (∩_∩) o haha ~
