This works as shown, but if you include the "if" statement, it doesn't work. (I'm new at this, and have searched everywhere I know of to find what's wrong - it must be simple)

<!DOCTYPE html>
<html>
<body>
<style>
.box { width: 80px; height: 80px; margin: 0px; padding:0px; border: 1px solid black; position: absolute; }
</style>
<script>
function swap(id) {
var a=document.getElementById(id).getAttribute("value")
// if a == "x" {
document.write(a);
// }
}
</script>
<div class="box" onclick="swap('00')" id="00" value="x"
</div>
</body>
</html>

<div class="box" onclick="swap('00')" id="00" value="x"

I'm sure you've solved it by now, but you forgot the > on the other side of the div class

Could you help us with what you’re trying to achieve? Maybe there’s a better alternative?

What I was trying to achieve was more complicated, I just reduced the code bit by bit to the smallest number of statements to isolate where my code was failing. It started as an attempt to set up a toggle switch (using the "value" fiield as a 1 or a 0) to change a background image back and forth by clicking on its container. This required the "if" statement to determine if the value was a 1 or a 0.

Use a Boolean for the value. Booleans are either True or False. Where as integers can be many different options.
