是否有一种简洁的方法将 Lua 表（作为字符串）转换为 JavaScript 数组？（反之亦然）

你可以手动将其转换为有效的 JSON 格式，然后再解析它：

const luaStr = `{
    ["glow"] = true,
    ["xOffset"] = -287.99981689453,
    ["yOffset"] = -227.55575561523,
    ["anchorPoint"] = "CENTER",
    ["cooldownSwipe"] = true,
    ["customTextUpdate"] = "update",
    ["cooldownEdge"] = false,
    ["icon"] = true,
    ["useglowColor"] = false,
    ["internalVersion"] = 24,
    ["keepAspectRatio"] = false,
    ["animation"] = {
        ["start"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
        ["main"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
        ["finish"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
    }}`;

const result = luaStr
  .replace(/\[|\]/g, '') // 删除括号
  .replace(/=/g, ':') // 将 = 替换为 :
  .replace(/(\,)(?=\s*})/g, ''); // 删除末尾逗号

const parsed = JSON.parse(result);

console.log(result);

这里有一些你可能不知道的东西，{ ["someString"]: 2 } 是有效的 javascript 并会被计算为 {someString: 2}，它也是有效的 json。唯一的问题是它需要被计算，这意味着需要使用 eval（如果可以避免的话，确实不应该这样做）。

const luaStr = `{
    ["glow"] = true,
    ["xOffset"] = -287.99981689453,
    ["yOffset"] = -227.55575561523,
    ["anchorPoint"] = "CENTER",
    ["cooldownSwipe"] = true,
    ["customTextUpdate"] = "update",
    ["cooldownEdge"] = false,
    ["icon"] = true,
    ["useglowColor"] = false,
    ["internalVersion"] = 24,
    ["keepAspectRatio"] = false,
    ["animation"] = {
        ["start"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
        ["main"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
        ["finish"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
    }}`;

const jsonString = luaStr.replace(/\] = /g, ']: ');
const jsonObj = eval(`(${jsonString})`);

console.log(jsonObj);

这只是一个局部解决方案。在一些字符串内部匹配关键字语法的情况下可能会失败。但这可能并不是您所关注的。

const lua = `
{
    ["glow"] = true,
    ["xOffset"] = -287.99981689453,
    ["yOffset"] = -227.55575561523,
    ["anchorPoint"] = "CENTER",
    ["cooldownSwipe"] = true,
    ["customTextUpdate"] = "update",
    ["cooldownEdge"] = false,
    ["icon"] = true,
    ["useglowColor"] = false,
    ["internalVersion"] = 24,
    ["keepAspectRatio"] = false,
    ["animation"] = {
        ["start"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
        ["main"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
        ["finish"] = {
            ["duration_type"] = "seconds",
            ["type"] = "none",
        },
    }
}`

const lua2json = lua =>
  JSON.parse(lua.replace(
    /\[([^\[\]]+)\]\s*=/g,
    (s, k) => `${k}:`
  )
  .replace(/,(\s*)\}/gm, (s, k) => `${k}}`))

console.log(
  lua2json(lua)
)

我不知道您是否想要创建JSON还是对象。我选择了后者，但您可以删除 JSON.parse 包装器。

Added array converting

         "test2" },

        ["test3"] = { "test1", "test2", "test2" },
    }}`;

const result = luaStr
.replace(/\[|\]/g, '') // 去除中括号
.replace(/=/g, ':') // 替换等号为冒号
.replace(/(\,)(?=\s*})/g, '') // 去除末尾的逗号
.replace(/\{\s*(\"[^".]*\"(\s*\,\s*\"[^".]*\")*)\s*\}/g, '[$1]') // 转换为数组

console.log (result)

const parsed = JSON.parse(result);
console.log(parsed);
