Example 1: type script edeode url
var decodeURI = decodeURIComponent("%26")
Example 2: decode ways javascript
var numDecodings = function(s) {
var len = s.length;
var tmp = 0;
var tmp1 = 1;
var tmp2 = 0;
var num1 = 0;
var num2 = 0;
if (s === '' || s[0] === '0') return 0;
for (var i = 1; i <= len; i++) {
num1 = Number(s.substr(i - 1, 1));
num2 = Number(s.substr(i - 2, 2));
if (num1 !== 0) tmp += tmp1;
if (10 <= num2 && num2 <= 26) tmp += tmp2;
tmp2 = tmp1;
tmp1 = tmp;
tmp = 0;
}
return tmp1;
