我尝试用html文件解析JavaScript中的csv文件，如下所示：

我尝试了一些像http://papaparse.com/这样的东西和库，但我有点担心一个值的多个数据（并不总是相同的数量），一个记录有多个条目。
答案 0 :(得分：2)
CSV的RFC规范不允许使用可变记录长度。
RFC 4180 CSV format section 2.4
要么修复输出CSV的代码（如果你可以控制它，这是理想的解决方案），那么它尊重规范，或者你可以使用split（）来做一个快速和脏的解析器。
请注意，如果你选择DIY路线，并且你已经在解析非标准的CSV，那么你可能会遇到各种各样的陷阱。例如，必须处理可能需要包含逗号/分号的值的双引号，或者首先输出的任何不符合规范的行为。
