sourceMap.findOrigin(lineNumber, columnNumber)

• lineNumber <number> 生成的源中调用站点的 1 索引行号

  ¥lineNumber <number> The 1-indexed line number of the call site in the generated source

• columnNumber <number> 生成源中调用站点的 1 索引列号

  ¥columnNumber <number> The 1-indexed column number of the call site in the generated source

• 返回：<Object>

  ¥Returns: <Object>

给定生成源中调用站点的 1 索引 lineNumber 和 columnNumber，在原始源中查找相应的调用站点位置。

¥Given a 1-indexed lineNumber and columnNumber from a call site in the generated source, find the corresponding call site location in the original source.

如果在任何源映射中都找不到提供的 lineNumber 和 columnNumber，则返回一个空对象。否则，返回的对象包含以下键：

¥If the lineNumber and columnNumber provided are not found in any source map, then an empty object is returned. Otherwise, the returned object contains the following keys:

• name <string> | <undefined> 源映射中范围的名称（如果提供）

  ¥name <string> | <undefined> The name of the range in the source map, if one was provided

• fileName <string> 原始源的文件名，如 SourceMap 中报告的那样

  ¥fileName <string> The file name of the original source, as reported in the SourceMap

• lineNumber <number> 原始源中相应调用站点的 1 索引行编号

  ¥lineNumber <number> The 1-indexed lineNumber of the corresponding call site in the original source

• columnNumber <number> 原始源中相应调用站点的 1 索引列编号

  ¥columnNumber <number> The 1-indexed columnNumber of the corresponding call site in the original source
