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

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";

15,718 PointsHey 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.
