js實現目錄鏈接,內容跟著目錄滾動顯示的簡單實例
編輯：關於JavaScript
如下所示：
<script>
require(["jquery", "bootstrap"], function($) {
$(function() {
$('.left').height(($('body').height() > $(window).height()) ? $('body').height() : $(window).height());
});
var goTo = $(".con");
var guide = $(".sideGuide");
var guideLi = $(".sideGuide li");
var index = 0;
var direct = 0;
var goToFun = function() {
var len = document.getElementById("box"+index).offsetTop-30; //獲取div層到頁面頂部的高度
direct = 0;
if (index < 0) {
index = 0;
return;
}
if (index >= guideLi.size()) {
index = guideLi.size() - 1;
return;
}
$("html,.tree").stop().animate({scrollTop: len}, 300, "swing", function() {
direct = 0;
});
guideLi.removeClass("on").eq(index).addClass("on");
}
guideLi.each(function(i) {
$(this).click(function() {
index = guideLi.index($(this));
goToFun();
})
});
/* 滾輪事件 */
var scrollFunc = function(e) {
e = e || window.event;
if (e.wheelDelta) {
direct += (-e.wheelDelta / 120);
} else if (e.detail) {
direct += e.detail / 3;
}
var first=document.getElementById("first").val();
if (direct >= first) {
goToFun(index++);
}
if (direct <= 0-first) {
goToFun(index--);
}
};
});
</script>
