This article will explain in detail how to achieve the function of imitating CSDN Blog to return to the top of the page. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Only two changes have been made:

The speed of return-- > changed to go back slowly. (it turned out to be a flash of return)

To return to the time when the top icon appears-> changed to display as long as it is not at the top. (originally displayed only after scrolling down the 500px)

Note: JS must be written after Html

HTML

The code is as follows:

Javascript code

The code is as follows:

$(function () {)

Var dumbtopping $('# dmurtopo')

_ document.onscroll=function () {

Var scrTop= (document.body.scrollTop | | document.documentElement.scrollTop)

If (scrTop > 500) {

If (scrTop > 0) {

D_top.show ()

} else {

D_top.hide ()

}

}

$('# dmurtopmura') .click (function () {

$("html,body") .animate ({scrollTop: 0} 500)

/ / scrollTo (0re0)

This.blur ()

Return false

});

});

CSS style

The code is as follows:

# d-top {

Position: fixed

Float: right

Z-index: 10

Right: 10px

Bottom: 40px

}

# d-top img {

Width: 42px
