参考免费微信小程序：皆我百晓生 作答，经由专家-皆知整理回复，如问题解决，望采纳；如仍有疑问，请评论回复。

根据提供的错误信息，问题出现在文件 D:/ShiXun/ex1/common/tuijian.js 的第110行。错误提示是 SyntaxError: Unexpected token, expected "," (110:0)，这意味着在这一行，JavaScript引擎期望看到一个逗号（,），但实际上遇到了一个它不期待的符号。

解决这类问题的步骤通常如下：

1. 检查第110行：首先，你需要打开这个文件，并直接定位到第110行。由于错误信息没有直接提供这行的具体内容，你需要自己查看。一般情况下，这可能是因为数组、对象字面量、函数参数列表等地方缺少了逗号，或者是在不应该有逗号的地方多了一个逗号。

2. 数组或对象语法：最常见的错误是在数组元素或对象属性之间忘记加逗号，或者在一个对象的最后一个属性后面多加了逗号。例如，在JavaScript中，虽然在对象的最后一个属性后面加逗号是ES6之后的可选语法，但某些旧环境或配置可能不支持。

3. 代码示例：假设错误是因为一个数组或对象定义，一个简单的修正可能是这样的（但这依赖于实际的代码内容）：

// 假设错误是因为这里
const myArray = [
    // ...其他元素
    // 这里原本可能缺少了逗号
    "最后一个元素",
]; // 如果这是错误的地方，确保最后一个元素后没有多余的逗号

// 或者是一个对象字面量
const myObject = {
    // ...其他属性
    // 确保每个属性后面都有逗号，除了最后一个
    "最后一个属性": "其值",
}; // 注意：ES6及以后版本允许最后一个属性后有逗号，但某些工具或老版本环境可能不接受

// 实际错误修复需要依据真实的代码内容

1. 检查临近代码：有时候，错误可能并非直接在报错的行上，而是前一行或多行的代码逻辑导致的。比如，一个未闭合的括号或数组。

2. 更新或检查Babel配置：如果项目使用了Babel进行转译，并且涉及到旧环境兼容，确保Babel配置正确，支持最新的语法特性，包括可选的尾随逗号（Trailing Commas）。

请按照上述指导检查和修改代码。如果问题依旧，提供具体的代码片段将有助于进一步诊断问题。
