Question

我试图从每个父div获取id以将其存储为变量，然后我可以将其用于视图站点按钮的href src。问题是，它只是抓住第一个id而不是抓住最接近或最相关的那个。

我使用prepend因为我将拥有数百个div，如果它只是一对我只会硬编码。但事实并非如此，那么任何人都可以提供帮助吗？

我附上了一个应该说明问题的代码片段，我的变量目前正在为href src删除一个未定义的内容。

$(document).ready(function() {

  //Set Variables  
  var Id = $(this).closest().attr('id');
  var Url = $('.box').css('background-image').split('/').pop().slice(0, -1).replace(/\.jpg/, '.htm');
  
//Create Links for Website Boxes
  $('.c').prepend('<div class="shadow"><div class="btn-wrap"><a href="' + Id + '" target="_blank">View Site</a><a href=" ' + Url + ' " target="_blank" >More Info</a></div></div>');
  


});

Answer 1

你真的很亲密！您可以为.closest()指定参数，它应该可以使用！

var id = $(this).closest("div").prop("id");

Answer 2

你可能想要这个：

    $(document).ready(function () {
        //Create Links for Website Boxes
        $('.box.c').each(function () {
            //Set Variables  
            var Id = $(this).attr('id');
            var Url = $(this).css('background-image').split('/').pop().slice(0, -1).replace(/\.jpg/, '.htm');
            $(this).prepend('<div class="shadow"><div class="btn-wrap"><a href="' + Id + '" target="_blank">View Site</a><a href="' + Url + ' " target="_blank" >More Info</a></div></div>');
        });
    });
