我想迭代这个主 div 以从每个子 div 获取每个数据。 有什么方法可以将此数据转换为 jquery 中的任何数组。 我试过 -

$('div.l-items.l-items-list.l-items-btn-right.l-items-offset').each(function(){
    var serviceName = $(this).find('div.l-item-header').text();
})

但我将所有服务名称作为一个元素获取。

我要:

[{"serviceName":"Women's Haircut", "price": "$80" }, {}, {}, ...]

我该怎么做？

有人可以帮我吗？

要从 jQuery 选择器中元素的属性构建数组，您可以使用 map() 方法并从中返回一个对象，如下所示:

var arr = $('.l-items .l-item').map(function() {
  return {
    serviceName: $(this).find('.l-item-header').text(),
    price: $(this).find('.l-app-price span:eq(1)').text()
  }
}).get();

console.log(arr);
