Help with manipulating DOM

Please help. I can't get the DOM to manipulate this input.

var test = document.getElementsByTagName("input")[9];

test returns: <input type=​"text" value=​"www.blahblah.com" size=​"50" name=​"WWWSiteURL" class=​"bullet">​…​</input>​

test.innerHTML = '<input type="text" value="test" size="50" name="WWWSiteURL" class="bullet">'; "<input type="text" value="test" size="50" name="WWWSiteURL" class="bullet">"

test returns: <input type=​"text" value=​"www.blahblah.com" size=​"50" name=​"WWWSiteURL" class=​"bullet">​…​</input>​

See, the input value should change to "test", but it stays as blah blah

Hey Tony,

Can you dump the HTML and JavaScript you have into a Codepen at Codepen.io and then paste the URL for the codepen here? I'd like to see the full code so that I can see what's going on.

Ok Marcus Parsons here's the link: http://codepen.io/raje101/pen/RPVYGX

I'm trying to change the field name "id" to have "test" as input.

Tony,

You can't change the innerHTML of an input element, but all you gotta do is target the input's value to change the text to "test". You can only change the innerHTML of a containing element, not the inside of the element itself.

var test = document.getElementsByTagName("input")[1];

test.value = "test";

No problem, Tony! If you need anything else, just holler at me!
