JQuery - Remove part of string and keep the rest

Question

I'm receiving multiple strings from a API and sometimes I have a string that looks like this.

first part <!-- Slut på Mall: variable --> second part

I want to use jQuery to exclude the part before and the "Slut... variable -->". Leaving me with the second part.

Just to be clear, the variable is dynamic and will change.

I have been playing around with replace, and match but so far I have failed. I have understood that regex is the way to go

regex = /Mall:.*\s+-->(.*)\z/

But I don't know what function to use with that?

Answer 1

var secondPart = "<!--" + yourApiString.split("<!--")[1];

Will return <!-- Slut på Mall: variable --> second part

Answer 2

If you wanted to still use a regex and replace, this is how you could go about it.

var x = "first part <!-- Slut på Mall: variable --> second part";
var y = x.replace(/.*<!--/, "<!--");

This replaces everything before <!-- including those four characters but ends up placing them back in.

If you just wanted "second part", then you could just do the following:

var y = x.replace(/.*-->/, "");

Thereby removing every character leading up to --> and itself.
