var txt;
var r = confirm("Press a button!");
if (r == true) {
   txt = "You pressed OK!";
} else {
   txt = "You pressed Cancel!";
}

var txt; var r =确认(“按下按钮!”); 如果(r == true) { txt = "You pressed OK!"; }其他{ txt = "You pressed Cancel!"; }

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

实践

<form name=myform>
<input type=button value="Try it now" 
onClick="if(confirm('Format the hard disk?'))
alert('You are very brave!');
else alert('A wise decision!')">
</form>

Web最初:

onclick处理程序应该在函数调用后返回false。如。

onclick = " ConfirmDelete ();返回错误;" >

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;
                        }

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?");
});
