使用步骤
如何使用
- 粘贴最多 100,000 个字符的纯文本。
- 选择 1 到输入行数之间的整数。
- 抽取行并检查或复制结果。
Without replacement
每次抽取都从不同的输入位置选择。不同输入行中的相同文本仍可能出现多次。
Bounded local input
The count must be a whole number from 1 through the number of input lines. Input is limited to 100,000 characters and 10,000 lines; blank lines count and selected line text is preserved.
Browser-only cryptographic randomness
Selection uses crypto.getRandomValues with rejection sampling to avoid modulo bias. Text is processed in this browser and is not uploaded or stored.
常见问题
你可能还想知道
同一行会被抽取两次吗?
不会,抽取不放回;不同输入行中的相同文本仍可分别参与抽取。
What happens when the requested count exceeds the input lines?
The tool reports an error and does not produce a partial result.
Are blank lines preserved?
Blank lines count as input lines and can be selected; selected line text is returned as-is.
