Bug：Unable to locate the point

I found a bug with an event listener inside, which made it impossible to locate the point
```js
function(e) {
if (!e.defaultPrevented) {
e.preventDefault(), location.hash !== this.hash && window.history.pushState(null, null, this.hash);
var n = document.getElementById(this.hash.substring(1));
if (!n) return;
t(n, 500, function(e) {
location.replace("#" + e.id)
})
}
}
```
