online search can use document.body.scrollTop, but I wrote a test in the project demo has no effect, why?
<button @click="opt"></button>
opt(){
if(document.body.scrollTop){
document.body.scrollTop = 0
}else {
document.documentElement.scrollTop = 0
}
},indicates that the scrolling container is not scrollTop of window or body, modified scrolling container
window.scrollTo (0L0)
is the demo of the subject in the autoScroll container? If so, no, otherwise the answer upstairs should be OK
print document.body.scrollTop if 0 means the scrolling container is not body, and see if there is a parent container overflow-y is auto | scroll , put its scrollTop=0
