容器不动。

    $(".scrollmenu").animate({left: '-=50'}, 'slow');
});

$("#right").on("click",function () {
    $(".scrollmenu").animate({left: '+=50'}, 'slow');

    height:45px;
    overflow:hidden;
}
.scrollmenu {
    width:300px;
    background-color: #333;
    overflow: auto;
    white-space: nowrap;

$("#left").click(function(event) { 
event.preventDefault();
     $(".scrollmenu").animate({ "left": "+=60px" }, "slow" );
});

$("#right").click(function(event) {
event.preventDefault();
   $(".scrollmenu").animate({ "left": "-=60px" }, "slow" );
});

.container {
    border:0px solid red;
    height:45px;
    overflow:hidden;
width:300px;
	background-color: #333;
}
.scrollmenu {
    width:100%;

    background-color: #333;
    overflow: visible;
    white-space: nowrap;
	position:relative;
	display: block;

.scrollmenu::-webkit-scrollbar {

.scrollmenu a {

                    <a href="#people">People</a>
                    <a href="#work">Work</a>
                </div>
            </div>
        </td>
        <td id="right">&#8594;</td>
    </tr>
</table>

现在需要添加一个脚本，以便在滚动溢出时停止
