🤖 AI解决方案
- 错误翻译：
com.script.ScriptException: org.mozilla.javascript.EvaluatorException: syntax error (<Unknown source>#5)
# 核心关键句：javascript 语法错误，在未知源的第 5 行。
JavaScript 代码在第 5 行存在语法错误。具体来说，
page=String(java.getString('.pagination@a.-2@html',result)).match(/\>(\d+)\ 这一行使用了可选链操作符 ?.，但执行环境（Rhino JavaScript 引擎）可能不支持此 ES11 特性。
解决方案：
移除可选链操作符 ?.，并进行空值检查。
let pans = type();
if (pans == '漫画') {
let burl = baseUrl;
result = java.ajax(burl);
// 移除 ?. 并进行空值检查
let matchResult = String(java.getString('.pagination@a.-2@html', result)).match(/\>(\d+)\</);
page = matchResult ? matchResult[1] : java.toast('不存在');
pageSum = parseInt(page);
}
预防措施：
* 在使用较新的 JavaScript 语法特性前，确认代码的运行环境是否支持。
* 对可能为 null 或 undefined 的值进行显式检查，避免因依赖链式调用而引发错误。
