JavaScript 正则表达式不会在逗号或制表符空间上拆分

Question

I am trying to split text from a file that could be a csv or tab delimited. Using split function with "," works for csv files, but when try and pass in a regex like this "/[\s,;\t\n]+/" bunches all the text together as one continuous string.

Is there a regex that will split the string whether the text is separated either by a comma or a tab? The files will only be either csv or tab delimited.

Answer 1

The regex /[,\t]/gm will find any comma or tab in a string. You can use it inside the split method in order to split the string. Your regex also find spaces for the \s and ;and line feed for \n (which you don't wrote you want split on). Down here you can see an example of how I used this regex.
