在按钮的onclick事件中写入以下内容:

var result = confirm("Want to delete?");
if (result) {
    //Logic to delete the item
}

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>

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>

<SCRIPT LANGUAGE="javascript">
function Del()
{
var r=confirm("Are you sure?")
if(r==true){return href;}else{return false;}
}
</SCRIPT>

你的链接:

<a href='edit_post.php?id=$myrow[id]'> Delete</a>

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>

它可以简化为:

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