Delete line starting with a word in Javascript using regex

Question

I have few lines on text.

Random 14637547548546546546sadas3463427
Random 1463754754854654654sadsa63463427
Macroflex 1463754754854654sada65

Answer 1

You have to replace to the end of the line:

var myRegex = data.replace(/^Macroflex.*$/m, '');

Note that you have to specify the m flag to let ^ and $ work with newlines.

If you want to remove the newline after the line, you can match it:

var myRegex = data.replace(/^Macroflex.*\n?/m, '');

This works since . does not match newlines.
