类似阿里云弹性计算的滑块

一个阿里云弹性计算的滑块，当然，与阿里云的还是有大差距哈。

查看演示

$(".track").mousedown(function() {
var target=$(this).parent();
isMoving=true;
$("html,body").mousemove(function(event) {
if(isMoving==false)return;
var changeX = event.clientX - ScrollerTrack.CurrentX;
currentValue = changeX - ScrollerTrack.CurrentX;
if(changeX<=0){
$(target).find(".track").css("margin-left", "0px");
$(target).find(".valueC").css("width", "0px");
$(target).find(".show").css("margin-left", "-15px");
$(target).find(".show").html(0);
ScrollerTrack.CurrentValue=0;
}
else if(changeX>=ScrollerTrack.BodyWidth-16){
$(target).find(".track").css("margin-left", ScrollerTrack.BodyWidth-16+"px");
$(target).find(".valueC").css("width",ScrollerTrack.BodyWidth-16+"px");
$(target).find(".show").css("margin-left", ScrollerTrack.BodyWidth-31+"px");
$(target).find(".show").html(ScrollerTrack.MaxValue);
ScrollerTrack.CurrentValue=ScrollerTrack.MaxValue;
}
else{
$(target).find(".track").css("margin-left", changeX+"px");
$(target).find(".valueC").css("width", changeX+"px");
$(target).find(".show").css("margin-left", changeX-15+"px");
var v=ScrollerTrack.MaxValue*((changeX+16)/ScrollerTrack.BodyWidth);
$(target).find(".show").html(parseInt(v));
ScrollerTrack.CurrentValue=parseInt(v);
}
});
});
