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>

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

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>

var x = confirm("Are you sure you want to send sms?");
if (x)
    return true;
else
    return false;  

对于“删除确认消息”使用:

                       $.ajax({
                        type: "POST",
                        contentType: "application/json; charset=utf-8",
                        url: "Searching.aspx/Delete_Student_Data",
                        data: "{'StudentID': '" + studentID + "'}",
                        dataType: "json",
                        success: function (data) {
                            alert("Delete StudentID Successfully");
                            return true;
                        }
