I need to replace string between two variable like this:

var str_before    = 'I Love My Cat So Much';
var start_mark    = 'My';
var end_mark      = 'So';
var str_replace   = 'Pussy Cat Very';

// Maybe

var after_replace = str_before.replace(start_mark, end_mark, str_replace);
// Replace String Between 'My' And 'So' With 'Pussy Cat Very'
// I Love Pussy Cat Very Much

Did you mean `/+ def + .*7/`? – Bergi Jan 30 '18 at 12:03
Oh sorry, yes like this one – Murphy'z law Jan 30 '18 at 12:15
So do you know how to fix it out? – Murphy'z law Jan 30 '18 at 12:32
The duplicate thread linked at the top of the page explains it. – Bergi Jan 30 '18 at 12:35
thanks but that one replace only one variable,but i need to replace between two variable (like replace 1 between 7 with something else) :( – Murphy'z law Jan 30 '18 at 13:11
What? Can you please [edit] your question to include the updated code that uses the `RegExp` constructor, and how it does not work? – Bergi Jan 30 '18 at 13:59
Here something like this.. – Murphy'z law Jan 30 '18 at 14:29

Wow. That question has nothing to do with regex any more. You might better [ask it as a new question](https://stackoverflow.com/questions/ask) – Bergi Jan 30 '18 at 14:34
That said, `str.replace(new RegExp("("+start+").*("+end+")"), "$1"+replacement+"$2")` might do (assuming that all the variables do not contain special characters, or they would need to be escaped) – Bergi Jan 30 '18 at 14:36
Oh @Bergi Thanks so much I want you to know how much I value your support... – Murphy'z law Jan 30 '18 at 14:47
