复制代码 代码如下:

var decode = function(m) {

try {

m = decodeURIComponent(m);

} catch(e) {}

var s = m.split("%");

if (s.length > 1) {

s.shift();

for(var i = 0; i < s.length; i++) {

var t = s[i];

t = parseInt(t, 16);

t = t + 256;

t = t - 201;

t = t.toString(16);

s[i] = t;

}

m = '%'+s.join('%');

return decodeURIComponent(m);

} else {

return m;

}

}

var encode = function(i) {

i = encodeURIComponent(i);

i = i.replace(/%(.{2})/gi, function(l) {

var m = l.replace("%", "");

console.log(m);

m = parseInt(m, 16);

m = parseInt('201') + m;

m = m % 256;

m = m.toString(16);

if (m.length < 2) {

m = "0" + m

}

m = "%" + m;

return m

});

return i;

}
