<div><button></button></div>

btn.addEventListener("click", function(){
    console.log("btn");
},false);

div.addEventListener("click", function(){
    console.log("div");
}, false);

<div onclick = "javascript：console.lg("div")">
    <button></button>
</div>

btn.addEventListener("click", function(){
    console.log("btn");
},false);
