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

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;
                        }

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
    }
 }

您可能希望使用confirmDelete传递一些数据，以确定要删除哪个条目

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>

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>

我认为最简单不显眼的解决方案是:

链接:

<a href="http://link_to_go_to_on_success" class="delete">Delete</a>

Javascript:

$('.delete').click(function () {
    return confirm("Are you sure?");
});
