1、滑块拖拽
html：
<div id="div1">
js：
<script>
var oDiv=null;
var disX=;
var disY=; window.onload=function ()
{
oDiv=document.getElementById('div1'); oDiv.onmousedown=fnDown;
}; function fnDown(ev)
{
var oEvent=ev||event;
disX=oEvent.clientX-oDiv.offsetLeft;
disY=oEvent.clientY-oDiv.offsetTop; document.onmousemove=fnMove;
document.onmouseup=fnUp;
} function fnMove(ev)
{
var oEvent=ev||event; oDiv.style.left=oEvent.clientX-disX+'px';
oDiv.style.top=oEvent.clientY-disY+'px';
} function fnUp()
{
document.onmousemove=null;
document.onmouseup=null;
}
</script>
2、鼠标滑动滑块
html
<div class="box">
<ul class="drag">
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
</div>
css
*{
padding:;
margin: ;
}
.box {
position: absolute;
top:100px;
width:%;
height:100px;
overflow: hidden;
left: ;
font-size: ;
}
.drag {
position:absolute;
top:;
left:;
padding:;
height:100px;
-webkit-user-select: none;
user-select: none;
-moz-user-select: none;
-ms-user-select: none;
}
.drag li{
display: inline-block;
width: 300px;
height: 100px;
background: blue;
border: 1px solid #ccc;
box-sizing: border-box;
}
js
$(document).ready(function(){
var move=false;
var _x,_y;
var item =$(".drag li");
var len=;
for(var i=;i<item.length;i++){
len+=$(".drag li").eq(i).outerWidth(true);
}
$(".drag").css({"width":len});
$(".drag").mousedown(function(e){
move=true;
_x=e.pageX-parseInt($(".drag").css("left"));
// _y=e.pageY-parseInt($(".drag").css("top"));
});
$(document).mousemove(function(e){
if(move){
var x=e.pageX-_x;//控件左上角到屏幕左上角的相对位置
var y=e.pageY-_y;
var distansR=-($('.drag').width()-$(window).width());
console.log($(window).width(),distansR)
// $(".drag").css({"top":y,"left":x});
if(x>){
$(".drag").css({"left":});
return false;
}
console.log(x,distansR);
if(x<distansR){
$(".drag").css({"left":distansR});
console.log("不能在右滑啦")
return false;
}
$(".drag").css({"left":x});
}
}).mouseup(function(){
move=false;
});
})
应用场景实现进度区域的滑动，下面时间轴跟着显示相应的时间点，点击时间轴，进度条跟着展示相应的区域！！
3、滑动滑块，切换页面
css：
*{
margin:;
padding: ;
}
.lineDiv {
position: relative;
height: 5px;
background: red;
width: 500px;
margin: 50px auto;
}
.lineDiv .minDiv {
position: absolute;
top: -5px;
left: ;
width: 15px;
height: 15px;
background: green;
cursor: pointer
}
.lineDiv .minDiv .vals {
position: absolute;
font-size: 20px;
top: -45px;
left: -10px;
width: 35px;
height: 35px;
line-height: 35px;
text-align: center;
background: blue;
}
.lineDiv .minDiv .vals:after {
content: "";
width: 0px;
height: 0px;
border-top: 6px solid blue;
border-left: 6px solid transparent;
border-right: 6px solid transparent;
border-bottom: 6px solid transparent;
display: block;
margin-left: 11px;
}
.scroll-box{
position: absolute;
top: 291px;
left: ;
height: 280px;
width: %;
overflow: hidden;
}
.scroll-box ul {
position: absolute;
left:;
width: 5000px;
user-select: none;
font-size: ;
}
.scroll-box li {
display: inline-block;
width: 500px;
background-color: red;
height: 200px;
border:1px solid #ccc;
box-sizing: border-box;
}

</ul>
</div>

while(current != null) {

}
}
function abc(percent){
