读取txt或者字符串中的aar函数代码，并通过loadcode() 来加载执行此函数

如题，有个需求是能过加载并执行一个txt或者ini文件中的字符串，这个字符串中包含需要被调用的函数方法，程序里要执行此方法。
import console;
var sss=/******
xieyi = function(str){
var dataStr = string.left(string.replace(str,"\s",""),4);
var ret = (10-tonumber(dataStr)*0.01);
return ret;
}
******/
var xx = loadcode(sss)
console.varDump(xx())
console.varDump(xieyi("50 01"))
console.pause(true);说一说注意关键点：
1，可以在字符串里添加
var str1,str2 = ...
来动态的获取外部提供的输入数据,但是这个数据需要在xx（str1,str2）的时候写
2，函数只需要执行一次xx（）初始化，之后就可以无限制的使用xieyi()函数了。

import console;
var sss=/******
xxtab={
{
geshi = "41";
xieyi = function(str){
var dataStr = string.left(string.replace(str,"\s",""),4);
var ret = (10-tonumber(dataStr)*0.01);
return ret;
}
};
{
geshi = "a3 50 01";
xieyi = function(str){
var dataStr = string.left(string.replace(str,"\s",""),4);
var ret = (tonumber(dataStr,16)*0.01 -100);
return ret;
}
}
}
******/
var xx = loadcode(sss)
console.varDump(xx())
console.varDump(xxtab[1].geshi)
console.varDump(xxtab[1].xieyi("50 01"))
console.varDump(xxtab[2].geshi)
console.varDump(xxtab[2].xieyi("50 01"))
console.pause(true);
如果把loadcode()改为loadcodex(),那么就可以少写一个执行初始化的语句了
import console;
var sss=/******
xxtab={
{
geshi = "41";
xieyi = function(str){
var dataStr = string.left(string.replace(str,"\s",""),4);
var ret = (10-tonumber(dataStr)*0.01);
return ret;
}
};
{
geshi = "a3 50 01";
xieyi = function(str){
var dataStr = string.left(string.replace(str,"\s",""),4);
var ret = (tonumber(dataStr,16)*0.01 -100);
return ret;
}
}
}
******/
//改为loadcodex之后，就会立即初始化一次这个函数，就不用手动xx()了
var xx = loadcodex(sss)
//console.varDump(xx())
console.varDump(xxtab[1].geshi)
console.varDump(xxtab[1].xieyi("50 01"))
console.varDump(xxtab[2].geshi)
console.varDump(xxtab[2].xieyi("50 01"))
console.pause(true);登录后方可回帖
更进一步：
如果字符串中是一个多维度Tab表，而且表里有字符串和函数，那么
import console; var sss=/****** xxtab={ geshi = "41"; xieyi = function(str){ var dataStr = string.left(string.replace(str,"\s",""),4); var ret = (10-tonumber(dataStr)*0.01); return ret; } } ******/ var xx = loadcode(sss) console.varDump(xx()) console.varDump(xxtab.geshi) console.varDump(xxtab.xieyi("50 01")) console.pause(true);
