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>

function confirmDelete()
{
var r=confirm("Are you sure you want to delte this image");
if (r==true)
{
//User Pressed okay. Delete

}
else
{
//user pressed cancel. Do nothing
    }
 }
<img src="deleteicon.png" onclick="confirmDelete()">

您可能希望使用confirmDelete传递一些数据，以确定要删除哪个条目

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>

HTML

<input onclick="return myConfirm();" type="submit" name="deleteYear" class="btn btn-danger" value="Delete">

Javascript

<script>
function myConfirm() {
  var result = confirm("Want to delete?");
  if (result==true) {
   return true;
  } else {
   return false;
  }
}

Angularjs与Javascript删除示例

html代码

<button ng-click="ConfirmDelete(single_play.play_id)" type="submit" name="actiondelete" value="1"><img src="images/remove.png" alt="Delete"></button>

“single_play。Play_id "是任意angularjs变量，假设你想在删除操作期间传递任何参数

app模块内的Angularjs代码

$scope.ConfirmDelete = function(yy)
        {
            var x = confirm("Are you sure you want to delete?");
            if (x) {
             // Action for press ok
                $http({
                method : 'POST',
                url : 'sample.php',
                headers: {'Content-Type': 'application/x-www-form-urlencoded'},
                data: $.param({ delete_play_id : yy})
                }).then(function (response) { 
                $scope.message = response.data;
                });
            }
            else {
             //Action for cancel
                return false;
            }
        } 

var txt;
var r = confirm("Press a button!");
if (r == true) {
   txt = "You pressed OK!";
} else {
   txt = "You pressed Cancel!";
}

var txt; var r =确认(“按下按钮!”); 如果(r == true) { txt = "You pressed OK!"; }其他{ txt = "You pressed Cancel!"; }
