Removing an onclick event from a div with javascript

Basically what the title says this is the code that I’ve tried but it doesn’t work:

<div id="box" onclick="doSmt(var1, bar2)">

if (condition){
box.removeEventListener("click" , doSmt)}

>Solution :

I think it’s better if you remove the onclick event instead of that attempt

//onclick function
function doSmt(){
   console.log("something");
}

//remove onclick event, this will be inside your if condition
document.getElementById('box').removeAttribute("onclick");

<div id="box" onclick="doSmt()"> div</div>
