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
}

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

function del_confirm(msg,url)
        {
            if(confirm(msg))
            {
                window.location.href=url
            }
            else
            {
                false;
            }

        }



<a  onclick="del_confirm('Are you Sure want to delete this record?','<filename>.php?action=delete&id=<?<id> >')"href="#"></a>

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
}

onclick处理程序应该在函数调用后返回false。如。

onclick = " ConfirmDelete ();返回错误;" >

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