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>

Answer 1

您可以使用event.relatedTarget函数有更多dynamic方法来获取data-attributes.

您不需要在此处使用内联函数，这可以使用本机引导函数onclick轻松完成，例如单击并获取数据属性并在模式中显示。jQueryshow.bs.modala

$("#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

})

      <div class="modal-footer">

        <button type="button" class="btn btn-primary">Save changes</button>

</div>

Answer 2

你可以这样做

<a href="javascript:void(0);" data-href="/sample/url" class="edit_product btn btn-sm btn-primary" data-toggle="modal" data-target="#editModal" onclick='process(this)'> Edit</a>

function process(inp) {

    console.log(inp.getAttribute('data-href'));

}

Answer 3

如果你使用 jQuery，那么你可以这样做

let hrefVal = null

$('.edit_product').click(function () { hrefVal = $(this).data('href') })
