php - Laravel中点击模态后如何获取标签的data-href值

Question

我有一个在单击“编辑”按钮时打开的模式，现在我想要 data-href 的值，在单击以回显模式主体内部时打开模式，我该怎么做

<a href="javascript:void(0);" data-href="{{ url('admin/product_edit/'.$cat->id) }}" class="edit_product btn btn-sm btn-primary" data-toggle="modal" data-target="#editModal"> Edit</a>

您可以使用event.latedTarget函数有更多动态方法来获取数据属性。

您不需要需要在此处使用内联onclick函数，这可以使用 native jQuery Bootstrap 函数(如)轻松完成show.bs.modal 并获取点击时的 a 数据属性并将其显示在模态中。

$("#editModal").on('show.bs.modal', function(event) {
  var button = $(event.relatedTarget) //Button that triggered the modal
  var getHref = button.data('href') //get button href
  $('#href').text(getHref) //show in the modal
})

现场工作演示:

$("#editModal").on('show.bs.modal', function(event) {
  var button = $(event.relatedTarget) //Button that triggered the modal
  var getHref = button.data('href') //get button href
  console.log(getHref) //{{ url('admin/product_edit/'.$cat->id) }}
  $('#href').text(getHref) //show in the modal
})
