I'm looking for a diff equivalent written in JavaScript that only returns/prints relevant lines. I don't want both full text displayed next to each other with the differences highlighted, but just want the actual differences (plus some buffer lines to know where the difference is), similar to the output from the linux diff utility.

Does anybody know a javascript function that does this? All differences should be recognized (even changed whitespace). Thanks.

JavaScript based diff utility

我正在寻找一个用JavaScript编写的diff等效项，它只返回/打印相关的行。我不希望两个全文并排显示，并突出显示差异，而只是想要实际的差异(加上一些缓冲区行来知道差异在哪里)，类似于linux diff实用程序的输出。有没有人知道javascript函数可以做到这一点？所有的差异都应该被识别出来(即使改变了空格)...
