Is there any way to erase the first part of this string?

Question

The following code is returning this: $100.00 - $209.00 but I need just the last value(without the dollar sign: 209.00

I'm sure that that's possible with regular expression. Does someone know how to do it?

The variable comes from Handlebar.

<span class="round">
   {{price<?php echo $priceKey; ?>_formatted}}
</span>

I'm expecting to transform the original to 209.00

I have to use javascript.

It's not necessarily regular expression. Could be anything that solves the issue.

Thanks

Answer 1

If your string is always is of same nature you can use split

 let str = "$100.00 - $209.00" let op = str.split('$').pop() console.log(op)

You can use match

.*\$(\d+(?:\.\d+)?)

 let str = "$100.00 - $209.00" let op = str.match(/.*\\$(\\d+(?:\\.\\d+)?)/) console.log(op[1])

Answer 2

'$100.00 - $209.00'.split('$')[2] isn't regex, but maybe the simplicity makes it better.

 console.log('$100.00 - $209.00'.split('$')[2])

I use [2] instead of [1] because of this behavior of the .split function :

If separator appears at the beginning or end of the string, or both, the array begins, ends, or both begins and ends, respectively, with an empty string.

Another alternative (without a regular expression) is to use String.slice() in conjunction with String.lastIndexOf() :

 let str = document.querySelector(".round").innerText; let formatted = str.slice(str.lastIndexOf("$") + 1); console.log(formatted);

 .as-console {background-color:black !important; color:lime;}

 <span class="round"> $100.00 - $209.00 </span>
