Question

I want to change div content,

this is my code:

<script type="text/javascript">
function changeText(){
    document.getElementById('df').value = 'changed';
}
</script>
<div id="df"></div>
<input type='button' onclick='changeText()' value='Change'/>

Nothing happens

Answer 1

You need innerHTML, not value

function changeText(){
    document.getElementById('df').innerHTML = 'changed';
}
