How to replace string between two strings in javascript?

Question

I had following string ,

const str= "this is harp//foo.eps and harp//data.eps"

I need to replace the string between harp to .eps

My code below,

const str = "this is harp//foo.eps and harp//data.eps"

const data = str.replace(/\harp.*\eps/, 'www.imge.jpg');

console.log(data);

it was returning output below,

this is www.imge.jpg

But expected output

this is www.imge.jpg and www.imge.jpg

I think you want the non-greedy version .*?

Try to make use non-greedy (?) search and global (/g) modifier:

const str  = "this is a harp//foo.eps and a harp//data.eps and harp//data.eps"
const data = str.replace(/harp(.*?)eps/g, 'www.imge.jpg');
console.log(data);

You can do it using the replace all function and the following regex

const str  = "this is harp//foo-two.eps and harp//data-9.eps"
const newSTr = str.replaceAll(/harp\/\/[A-Za-z\-0-9]+\.eps/g, 'www.imge.jpg')
console.log(newSTr);
