我用这种方法(laravel)-

<form id="delete-{{$category->id}}" action="{{route('category.destroy',$category->id)}}" style="display: none;" method="POST">
 @csrf
 @method('DELETE')
</form>

<a href="#" onclick="if (confirm('Are you sure want to delete this item?')) {
           event.preventDefault();
           document.getElementById('delete-{{$category->id}}').submit();
         }else{
           event.preventDefault();
         }">
  <i class="fa fa-trash"></i>
</a>

HTML:

<a href="#" class="delete" data-confirm="Are you sure to delete this item?">Delete</a>

使用jQuery:

$('.delete').on("click", function (e) {
    e.preventDefault();

    var choice = confirm($(this).attr('data-confirm'));

    if (choice) {
        window.location.href = $(this).attr('href');
    }
});

它非常简单，只有一行代码

<a href="#" title="delete" class="delete" onclick="return confirm('Are you sure you want to delete this item')">Delete</a>

改进user1697128(因为我还不能评论它)

<script>
    function ConfirmDelete()
    {
      return confirm("Are you sure you want to delete?");
    }
</script>    
    
<button Onclick="return ConfirmDelete();" type="submit" name="actiondelete" value="1"><img src="images/action_delete.png" alt="Delete"></button>

如果按“取消”键，会取消提交表格吗

function del_confirm(msg,url)
        {
            if(confirm(msg))
            {
                window.location.href=url
            }
            else
            {
                false;
            }

        }



<a  onclick="del_confirm('Are you Sure want to delete this record?','<filename>.php?action=delete&id=<?<id> >')"href="#"></a>

下面是纯JS中使用className和绑定事件的另一个简单例子。

var eraseable = document.getElementsByClassName("eraseable"); for (var i = 0; i < eraseable.length; i++) { eraseable[i].addEventListener('click', delFunction, false); //bind delFunction on click to eraseables } function delFunction(){ var msg = confirm("Are you sure?"); if (msg == true) { this.remove(); //remove the clicked element if confirmed } }; <button class="eraseable"> <img class="eraseable" src="http://zelcs.com/wp-content/uploads/2013/02/stackoverflow-logo-dumpster.jpg" style="width:100px;height:auto;"> Delete me</button> <button class="eraseable"> <img class="eraseable" src="http://zelcs.com/wp-content/uploads/2013/02/stackoverflow-logo-dumpster.jpg" style="width:100px;height:auto;"> Delete me</button> <button class="eraseable"> <img class="eraseable" src="http://zelcs.com/wp-content/uploads/2013/02/stackoverflow-logo-dumpster.jpg" style="width:100px;height:auto;"> Delete me</button>
