Using replace, but because javascript doesn't have lookbehinds, you need to replace it with a string concatenated with slashes:

var x = 'abcd/data/efgh';
var s = 'newtext';
console.log(x.replace(/\/[^/]+\//, '/'+s+'/'));// gives: abcd/newtext/efgh

Have e try with:

'abcd/data/efgh'.replace(/\/[^/]+\//, '/newtest/')

Output:

abcd/newtest/efgh

Try this:

"abcd/data/efgh".replace(/\/(.+)\//, '/newtext/')

or

"abcd/data/efgh".replace(/^(.+\/)(.+)(\/.+)$/, '$1newtext$3')

you should try this code snippet

var x = 'abcd/data/efgh';
var s = 'newtext';
console.log(x.replace(/(/.[^/]+/)/g, '/'+s+'/'));

Hope this would help you. Thanks!!
