在每个第二期之后添加换行符

Question

I'm looking for a solution to separate a long JSON string with line-breaks after each 2nd period.

What's wrong with this regex?

var text = 'Lorem ipsum dolor. Consetetur sadipscing elitr. Sed diam nonumy eirmod tempor invidunt';

text.replace(/(\.(\s+))/g, '\$1 <br><br>');

// Expected behaviour
// Lorem ipsum dolor. Consetetur sadipscing elitr. <br><br>Sed diam nonumy eirmod tempor invidunt

// Current behaviour
// Lorem ipsum dolor. <br><br>Consetetur sadipscing elitr. <br><br>Sed diam nonumy eirmod tempor invidunt

Answer 1

The following should work:

text.replace(/(\.[^.]*\.)/g, '$1 <br><br>');

The [^.]* will match any number of characters that are not periods, so this regex will match exactly two periods with anything in between them.

Answer 2

An alternative:

text.replace(/(.*?\.){2}/g, '$& <br><br>')

This will expect two chunks of text with a period, then replace them with the match followed by line breaks.

You could easily play with the number if you feel like making the breaks more sparse.
