function ConfirmDelete()
{
  return confirm("Are you sure you want to delete?");
}


<input type="button" onclick="ConfirmDelete()">

试试这个。这对我很有用

 <a href="delete_methode_link" onclick="return confirm('Are you sure you want to Remove?');">Remove</a>

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!"; }

它可以简化为:

<button onclick="return confirm('Are you sure you want to delete?');" />

function ConfirmDelete()
{
  return confirm("Are you sure you want to delete?");
}


<input type="button" onclick="ConfirmDelete()">

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');
    }
});
