js加密函数

function(ret) {
    if (ret.data == 'no') {
        return false;
    } else {
        var data = ret.data ;//服务器发送的字符串
        var scode = data.split("#")[0];
        var sxh = data.split("#")[1];
        var code = document.getElementById("Form1").USERNAME.value + '%%%' + document.getElementById("Form1").PASSWORD.value;
        var encoded = '';
        for (var i = 0; i < code.length; i++) {
            if (i < 20) {
                encoded = encoded + code.substring(i, i + 1) + scode.substring(0, parseInt(sxh.substring(i, i + 1)));
                scode = scode.substring(parseInt(sxh.substring(i, i + 1)), scode.length);
            } else {
                encoded = encoded + code.substring(i, code.length);
                i = code.length;
            }
          //加密后结果
          encode = encode 
        }

python简化后的加密函数

        scode = scode[index:len(scode)]
