Combined with the ideas on the Internet, coupled with the code I made before, the code has these functions:
1. The contents of the head and tail can be scrolled without scrolling, as long as they are scrolled in the middle.
two。 Support the animation trigger of the previous screen and the next screen
3. Support the next page and previous page navigation jump
4. Support mini navigation display and jump to a page
HTML Code:
Header
Page1
Page2
Page3
Page4
next page
Footer
When setting CSS, you need to note that there are two parent class elements, and the outermost one should be set beyond the height of hiding.
.doc {height:640px;position:relative;overflow:hidden}
.main {position:relative}
.doc .page {position:absolute;height:100%;width:100%;top:100%}
.doc.done .page {position:static;top:0}
JS code, note that the scrolling compatible code uses the jQuery plug-in jquery-mousewheel. Don't miss this plug-in.
JS:
$(function () {)
Var onScroll = false
CurIndex = 0
Len = $(".doc .page") .length
Var winHeight = $(window) .height ()
/ / var boxHeight = winHeight- 60 > 640? WinHeight-60: 640; / / when you need to display all the content, you need to give the outer layer a fixed height to ensure that all the content can be seen.
Var boxHeight = winHeight-60
Var toPage = function (curIndex) {
OnScroll = true
Var now =-curIndex * boxHeight
$(".page") .eq (curIndex) .addClass ("current") .siblings (".page") .removeClass ("current")
$(".page-nav I") .eq (curIndex) .addClass ("current") .siblings ("I") .removeClass ("current")
(".main") .animate ({
Top: now + "px"
}, 1000 times function () {
OnScroll = false
});
}
$(".doc") .css ("height", boxHeight)
$(".main") .css ("height", boxHeight * len)
(".page") .css ("height", boxHeight)
$(".doc") .addClass ("done")
Var pageNext = function () {
If (curIndex = = len-1) return
CurIndex++
ToPage (curIndex)
}
Var pagePrev = function () {
If (curIndex = = 0) return
CurIndex--
ToPage (curIndex)
}
(".doc") .on ("mousewheel", function (e, I) {
If (onScroll) return
If (I <-.2) {
/ / Scroll down
PageNext ()
} else {
/ / scroll up
PagePrev ()
}
});
$('.nextPage') .on ('click',function () {
If (onScroll) return
PageNext ()
});
$('.page-nav i') .on (' click',function () {
If (onScroll) return
Var index = $(this) .index ()
ToPage (index)
})
});
