aardio群友的问题,web.script用xcall调用javascript函数不成功什么原因?

电脑计算机编程入门教程自学编程语言,aardio教程,

原问题的源码如下:

import win.ui;

/*DSG{{*/

var winform = win.form(text="aardio form";right=759;bottom=469)

winform.add()

/*}}*/



import console;

var js = /**

        function getTime(){

            var rckey = +(new Date()) + ''

            return rckey; 

        }    

        **/

        

var js2 = /**



    function doencryptrc(src, passwd) {

        src = (src+'').trim();

        passwd = passwd + '';

        var i, j = 0, a = 0, b = 0, c = 0, temp;

        var plen = passwd.length,

            size = src.length;

    

        var key = Array(256); //int

        var sbox = Array(256); //int

        var output = Array(size); //code of data

        for (i = 0; i < 256; i++) {

            key[i] = passwd.charCodeAt(i % plen);

            sbox[i] = i;

        }

        for (i = 0; i < 256; i++) {

            j = (j + sbox[i] + key[i]) % 256;

            temp = sbox[i];

            sbox[i] = sbox[j];

            sbox[j] = temp;

        }

        for (i = 0; i < size; i++) {

            a = (a + 1) % 256;

            b = (b + sbox[a]) % 256;

            temp = sbox[a];

            sbox[a] = sbox[b];

            sbox[b] = temp;

            c = (sbox[a] + sbox[b]) % 256;

            temp = src.charCodeAt(i) ^ sbox[c];//String.fromCharCode(src.charCodeAt(i) ^ sbox[c]);

            temp = temp.toString(16);

            if (temp.length === 1) {

                temp = '0' + temp;

            } else if (temp.length === 0) {

                temp = '00';

            }

            output[i] = temp;

        }

        return output.join('');

    }

**/

import web.script;

runJS = web.script();

runJS.addCode(js)

runJS.addCode(js2)

console.log(runJS.xcall("doencryptrc",tostring("Dxs54175!!"),"111111111111"))



winform.show();

win.loopMessage();

经群友探讨,原因是:

(src+'').trim(); 是这里不支持 trim 用法,不是函数有问题.

aardio中的web.script 是基于IE的, 不支持很多新版JS的特性, 比如 const, async, promise

由于web.script 的 js 引擎版本太低了, String没有trim() 方法
