Question

Using the jQuery text function I received a string that contains a lot of carriage returns/line breaks in sequence.

For example, “\r\n \r\n \r\n Welcome Bob\r\n\t \r\n\r\n\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Recommendation: Hellot\r\n\r\n\r\n \r\n \r\n\r\n \r\n \r\n \r\n \r\n\r\n \r\n \r\n” .

Is it possible to have just one line break instead of a sequence using JavaScript, presumably replace function?

Answer 1

Use

str.replace(/\s*?[\r\n]\s*/g, "\n");

to match any whitespaces around your carriage returns/linebreaks and replace them by \n altogether.
