获取第一个单词和换行符之间的内容

Question

I would like to get the value of a line between the first word and the line break at the end. for example:

foo bar bob
hello hi

I want to get "bar bob" by asking for line "foo".

Answer 1

I found it.

var str='foo bar baz'
var estr = str.replace(/^.*? (.*)/i,"$1" )

Answer 2

This will work for you

var str = "foo bar\n";
str.slice(str.indexOf(' ')+1,str.indexOf('\n')); //returns bar
