I'm facing some. Problem suppose I have element with id="Container" in html and I access it using js

Question

var con = document.getElementById("Container")

And inside container I have 2 buttons one with id="edit" and one with "delete"

When I use this query to access buttons there is no problem

con.getElementsByTagName("button")[0]
con.getElementsByTagName("button")[1]

But when I try this I get error

con.getElementById("edit")
con. getElementById("delete")

Answer 1

Shivam Rawal because con already consist getElementById.

You can't do

getElementById (). getElementById ()

Answer 2

What value is set for ID attribute of the buttons? did they match the argument you pass to getElementById?

(Edit)
You can use `con.querySelector("#edit")` instead. `getElementById` was not bound to <con> apparently.

Answer 3

The accessing will be created with:

document.getElementById("edit"); // or any other id
