本文实例为大家分享了js实现滑动导航栏效果的具体代码，供大家参考，具体内容如下
*{
margin: 0;
padding: 0;
}
.navScroll{
position: relative;
}
#overflow{
width: 100%;
height: 30px;
overflow-x: scroll;
}
#overflow .container{
height: 30px;
}
#overflow .container div{
float: left;
width: 100px;
height: 30px;
line-height: 30px;
text-align: center;
}
#overflow::-webkit-scrollbar {
display: none;
-webkit-overflow-scrolling: touch;
}
.navScroll .drop_down{
position: absolute;
top: 0;
right: 0;
width: 50px;
height: 30px;
}
.navScroll .drop_down img{
width: 100%;
height: 100%;
}
.tabUl.clearFix{
display: none;
width: 100%;
list-style: none;
z-index: 10;
background: rgba(0,0,0,.1);
}
.tabUl li{
float: left;
width: 6.25rem;
height: 2.65625rem;
line-height: 2.65625rem;;
text-align: center;
}
.clearFix{
content: "";
display: table;
clear: both;
}
div, ul{
color: #89CFE8;
}
#overflow .container div.lastWidth{
width: 50px;
}
.red{

var width = 0;
$('#overflow .container div').each(function () {

});
$('#overflow .container').css('width', width + "px");
var flag = true;
$(".drop_down img").click(function(e){ //箭头符号的变化
if(flag){

}
});
var ulHeight= Math.ceil(($(".tabUl li").length-1)/6)*2.65625 +"rem";
$(".navScroll .tabUl").css("height",ulHeight)
$(".navScroll").on("click",".tabItem",function(e,index){ //滑动栏点击样式
var $this=$(this);
$(".tabItem").css({"color": "#89CFE8"})
$($this).css({"color": "#FF9933"});
var items = $($this)[0];
var ulIndx;
$(".tabItem").each(function(i,n){
if(n==items){
ulIndx = i;
}
})
$(".tabUl li").css({"color": "#89CFE8"});
var ulItems = $(".tabUl li")[ulIndx];
$(ulItems).css({"color": "#FF9933"});
moveNav(ulIndx);
})
$(".navScroll").on("click","li",function(e,index){ //下拉点击样式
var $this=$(this);
$("li").css({"color": "#89CFE8"})
$($this).css({"color": "#FF9933"});
var items = $($this)[0];
var ulIndx;
$("li").each(function(i,n){
if(n==items){

}
})
$(".tabItem").css({"color": "#89CFE8"});
var ulItems = $(".tabItem")[ulIndx];
$(ulItems).css({"color": "#FF9933"});
$(".drop_down img").attr("src","img/icon_events_fold.png");
$(".tabUl").css("display","none")
flag = true;
moveNav(ulIndx);
})
function moveNav(index){ //滑动栏移动效果
var allImg = $(".navScroll").find(".tabItem");
var navImgWidth = allImg.width();
var lastWidth = $(".container .lastWidth").width();
var windowWidth = $(window).width();
var navBox = $("#overflow");
if(navImgWidth*(index+1) >=windowWidth-navImgWidth){
if(navImgWidth*(index+1)
navBox.animate({scrollLeft:navImgWidth*(index+1)},500);
}else{
navBox.animate({scrollLeft:navImgWidth*(allImg.length)+lastWidth-windowWidth},500);
}
}else{
navBox.animate({scrollLeft:'0px'},1000);
}
}
导航栏可滑动
下拉点击会相应的改变导航栏
