如何停止onclick事件？

Question

I'd like to stop onclick if I pressed it twice, but somehow it doesn't work...
what am I doing wrong?

var timer
timer = document.querySelector("#home").onclick = function () {
  setTimeout(function(){ alert("Expenses"); }, 1000);
}
console.log(timer);

document.querySelector("#home").setAttribute("ondblclick", "buildActionButton()");


function buildActionButton() {
  timer.stopPropagation();
  alert("ActionButton");
}

You need to create the event using 'addEventListener' instead of just changing its 'onclick' property. You can then use 'removeEventLister' to remove the 'onclick' event.
