Question

i want to select a sting from the long para. it has number of dot(‘.’)s. i want to trim the word from the second one, is it any way to do this?

example

var name = "one.two.three";
name.substring(0,name.indexOf('.'))
name.substring(0,name.lastIndexOf('.'))

from above trimming in case if i use indexOf it gives first word (one), if i use lastIndex of it gives the word (three), but i need to select the second one, to get value as ‘second’

how can i trim this using indexOf method? or to select multicombination strings like one.three or one.two, or two.three?

thanks in advance!

Answer 1

var name="one.two.three";
var result=name.split(".").slice(0,2).join(".");

Example:

"".split(".").slice(0,2).join(".") // return ""
"one".split(".").slice(0,2).join(".") // return "one"
"one.two".split(".").slice(0,2).join(".") // return "one.two"
"one.two.three".split(".").slice(0,2).join(".") // return "one.two"
"one.two.three.four.five".split(".").slice(0,2).join(".") // return "one.two"
