HTML:

<a href="#" class="delete" data-confirm="Are you sure to delete this item?">Delete</a>

使用jQuery:

$('.delete').on("click", function (e) {
    e.preventDefault();

    var choice = confirm($(this).attr('data-confirm'));

    if (choice) {
        window.location.href = $(this).attr('href');
    }
});

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;
                        }

<form onsubmit="return confirm('Are you sure?');" />

适用于表单。表单特定的问题:JavaScript表单提交-确认或取消提交对话框

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!"; }

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

这就是使用不引人注目的JavaScript和在HTML中保存确认消息的方式。

<a href="/delete" class="delete" data-confirm="Are you sure to delete this item?">Delete</a>

这是一个纯香草JS，兼容IE 9+:

var deleteLinks = document.querySelectorAll('.delete');

for (var i = 0; i < deleteLinks.length; i++) {
  deleteLinks[i].addEventListener('click', function(event) {
      event.preventDefault();

      var choice = confirm(this.getAttribute('data-confirm'));

      if (choice) {
        window.location.href = this.getAttribute('href');
      }
  });
}
