这些是一组 div，我想在其中添加一些循环。
我已经尝试过 jquery 和 javascript 但没有用。请帮忙。
它从复选框中获取计数，计数是在复选框中选择的值，需要动态填充以下一组 div。我写了一个 jquery 来获取计数和复选框值。当用户选择这些框时，div 集需要显示为计数数。
function arrayValues(item, index)
{
var cd = $("input[name=car_damage]:checked");
var eg = cd.map(function () {return this.value;}).get().join(",");
var temp = new Array();
temp = eg.split(",");
text="";
alert(temp);
//alert(eg);
var ef = cd.size();
alert(ef);
}
复选框代码:

不清楚您正在寻求的解决方案。
然而，需要最少工作量的是创建一个函数来执行更改和 jquery 来操作您的 DOM 元素，这不是一个很好的解决方案，但如果您需要状态管理。
我相信更好的解决方案是使用 reactjs，它可以创建组件并利用 jsx。
或者 AngularJS 框架，您可以在其中执行 ng-repeat 或自定义指令，接收输入以显示您的 div。
