它可以简化为:

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

如果你对一些快速漂亮的解决方案与css格式感兴趣，你可以使用SweetAlert

$(function(){ $(".delete").click(function(){ swal({ title: "Are you sure?", text: "You will not be able to recover this imaginary file!", type: "warning", showCancelButton: true, confirmButtonColor: "#DD6B55", confirmButtonText: "Yes, delete it!", closeOnConfirm: false }).then(isConfirmed => { if(isConfirmed) { $(".file").addClass("isDeleted"); swal("Deleted!", "Your imaginary file has been deleted.", "success"); } }); }); }); html { zoom: 0.7 } /* little "hack" to make example visible in stackoverflow snippet preview */ body > p { font-size: 32px } .delete { cursor: pointer; color: #00A } .isDeleted { text-decoration:line-through } <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script> <script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script> <link rel="stylesheet" href="http://t4t5.github.io/sweetalert/dist/sweetalert.css"> <p class="file">File 1 <span class="delete">(delete)</span></p>

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;
  }
}

这就是使用不引人注目的JavaScript和在HTML中保存确认消息的方式。

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

这是一个纯香草JS，兼容IE 9+:

var deleteLinks = document.querySelectorAll('.delete');

for (var i = 0; i < deleteLinks.length; i++) {
  deleteLinks[i].addEventListener('click', function(event) {
      event.preventDefault();

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

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

看到它的行动:http://codepen.io/anon/pen/NqdKZq

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

我想提供我的方法:

<form action="/route" method="POST">
<input type="hidden" name="_method" value="DELETE"> 
<input type="hidden" name="_token" value="the_token">
<button type="submit" class="btn btn-link" onclick="if (!confirm('Are you sure?')) { return false }"><span>Delete</span></button>
</form>
