How to add a new attribute to a tag

<input  id="test" value="123" name ="test"  verify="NOTNULL">

In some HTML, I saw the input tag has the attribute verify. How to add it to the input tag?

I tried the code 

alert(document.getElementById("test").verify)

the result is undefined.

How do I add a new attribute to the element?

Adding an attribute with pure Javascript is done via setAttribute

document.getElementById("test").setAttribute("verify","verified");

And to read it:

document.getElementById("test").getAttribute("verify")

If you mean to say that the html input element has a [verify] attribute, then you can access the attribute via getAttribute():

HTML: 
<input id="test" verify="test" />
JS: 
document.getElementById('test').getAttribute('verify'); //test
