You have some problems in your HTML it is not valid, you can't run JavaScript from a style attribute.
You can run Javascript from within a <script> tag which really is the best way to do it.
<script>
document.getElementById("demo").innerHTML = "Hello JavaScript!";
</script>
Alternatively there are some HTML elements that allow you to execute it on some events, like onchange , onclick etc.
<select onchange="myFunction()">
<button onclick="myFunction()">Click me</button>
https://www.w3schools.com/ is a great resource for learning more about each html element, and also JavaScript as a whole.
Good luck

can you please tell here which java script framework is you are using? you can achieve this by using and template java script framework like Angular, React... If u dont want to use any framework than you need to write pure javascript or jquery code for assigning the background css prop.
for entire body,
document.body.style.backgroundImage = "url('img_tree.png')";
for div,
document.getElementById("mycode").style.backgroundImage = "url('img_tree.png')";

Answer : Open script in footer
<script>
$( "#mycode" ).click(function() {
alert( "Hai" );
});
</script>

You can target HTML tag using getElementById() and then apply custom style like this document.getElementById("Mydiv").style.backgroundColor="#0000"
or apply a bunch of styles like this
var dev = document.getElementById("Mydiv");
dev.style.backgroundColor="#0000";
dev.style.fontSize="..";
dev.style.backgroundImage="..";

You can run your function using "onerror" event. And also you must do some error in that case. For eg.
<img src="someFakeSrc" onerror='javascript:eval(window.alert("sometext"))'>
HTML doesn't see a src of picture then run a 'onerror' event.
