使用jQuery:

$(".delete-link").on("click", null, function(){
        return confirm("Are you sure?");
    });

您可以更好地使用以下方法

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</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');
    }
});

<script>
function deleteItem()
{
   var resp = confirm("Do you want to delete this item???");
   if (resp == true) {
      //do something
   } 
   else {
      //do something
   }
}
</script>

使用onClick调用此函数

它可以简化为:

<button onclick="return confirm('Are you sure you want to delete?');" />

当你在PHP和mysql中删除一些东西时，设置一个确认消息…

使用以下脚本代码:

<script>
    function Conform_Delete()
    {
       return conform("Are You Sure Want to Delete?");
    }
</script>

使用下面的HTML代码:

<a onclick="return Conform_Delete()" href="#">delete</a>
