Need to read a value using javascript

Question

I need a javascript that can read the value of this:

<div id="timer" >07.45</div>

,it's a timer and it counts from 20 seconds, it counts down in seconds and miliseconds , so how can I get let's say 07.45 value to be shown! This is what I tried but it doesn't work, it shows undefined

<div id="timer">07.45</div>    
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var x = document.getElementById("timer").value;
document.getElementById("demo").innerHTML = x;}
</script>

Welcome to StackOverflow! The format here is that of a question and answer site, and in order for a question to be valid we need to know what it is your trying to do(check), what your end result should be(check), and what you have tried(please add). Your question could use a bit better formatting as well! — zfrisch

I'm voting to close this question as off-topic because the effort the OP put into researching / trying is too low to be acceptable — Jonas Wilms

Generally speaking, div elements don't have values. You might want the innerHtml instead. — bmb

if I understand your question,

you're having trouble with the reading of value.

function myFunction() {
document.getElementById("demo").innerHTML = document.getElementById("timer").innerHTML;
}

You can also read some DOM documentation around the web. Hope can help.
