我正在制作一个使用 JSON 填充的 jQuery 轮播。我需要它在最后停下来。我通过将列表项的数量乘以列表项的宽度来计算列表的宽度，因此可以在不更改 CSS 中的宽度的情况下添加新项目。这是我的代码

滑块.js

$(document).ready(function() {
var w = $("#carouselList").css("width");

var slider = $("#carouselList");
var leftProperty, newLeftProperty;


$("#rightButton").click(function(){
    leftProperty = parseInt(slider.css("left"));

    if (leftProperty - 991 <= -w) {
        newLeftProperty = 0;

        }
    else {
        newLeftProperty = leftProperty - 304;

         }



    slider.animate({left: newLeftProperty}, 500);

    });

$("#leftButton").click(function(){
    leftProperty = parseInt(slider.css("left"));

    if (leftProperty < 0){
        newLeftProperty = leftProperty + 304;


    }

    else {
        newLeftProperty = 0;
    }

    slider.animate({left: newLeftProperty}, 500);
});
});
