原JS代码

function b(a, b) {for (var d = 0; d < b.length - 2; d += 3) {var c = b.charAt(d + 2),c = "a" <= c ? c.charCodeAt(0) - 87 : Number(c),c = "+" == b.charAt(d + 1) ? a >>> c : a << c,a = "+" == b.charAt(d) ? a + c & 4294967295 : a ^ c}return a
}function tk(a,TKK) {for (var e = TKK.split("."), h = Number(e[0]) || 0, g = [], d = 0, f = 0; f < a.length; f++) {var c = a.charCodeAt(f);128 > c ? g[d++] = c : (2048 > c ? g[d++] = c >> 6 | 192 : (55296 == (c & 64512) && f + 1 < a.length && 56320 == (a.charCodeAt(f + 1) & 64512) ?(c = 65536 + ((c & 1023) << 10) + (a.charCodeAt(++f) & 1023), g[d++] = c >> 18 | 240, g[d++] = c >> 12 & 63 | 128) : g[d++] = c >> 12 | 224, g[d++] = c >> 6 & 63 | 128), g[d++] = c & 63 | 128)}a = h;for (d = 0; d < g.length; d++) a += g[d],a = b(a, "+-a^+6");a = b(a, "+-3^+b+-f");a ^= Number(e[1]) || 0;0 > a && (a = (a & 2147483647) + 2147483648);a %= 1E6;return a.toString() + "." + (a ^ h)
