Getting a input by name then getting its value

Question

I'm trying to get the input by its name, then get its value, but this isn't working.

token = document.getElementsByName("__RequestVerificationToken").value
console.log(token)

The token:

<input name="__RequestVerificationToken" type="hidden" value="LXRZObY_ZLZ5pIjUd7fGgWONkAqJvXD6queBT3pod0ofwCXG2IhtEywSuaJOGVsjUIvKPyW60irAgP_fKslonLMFww41">

i think getElementsByName return as array.. so do document.getElementsByName("__RequestVerificationToken")[0] should work. — aahhaa, Jul 02 '15 at 15:54

Look on https://jsfiddle.net/qwdbny7v/1/ best way to do it is use getElementById,or jquery way. — Michał Ignaszewski, Jul 02 '15 at 16:04

the method "getElementsByName" returns an array so you have to chose the item in the array:

token = document.getElementsByName("__RequestVerificationToken")[0].value
console.log(token)

It returns an array-like nodeList, it's not actually an array. You won't have access to any array methods. – Jesse Kernaghan Jul 02 '15 at 15:59

You just need to add [0] to select your element value:

token = document.getElementsByName("__RequestVerificationToken")[0].value
alert(token)

<input name="__RequestVerificationToken" type="hidden" value="LXRZObY_ZLZ5pIjUd7fGgWONkAqJvXD6queBT3pod0ofwCXG2IhtEywSuaJOGVsjUIvKPyW60irAgP_fKslonLMFww41">
