<script>
function deleteItem()
{
   var resp = confirm("Do you want to delete this item???");
   if (resp == true) {
      //do something
   } 
   else {
      //do something
   }
}
</script>

使用onClick调用此函数

HTML

<input onclick="return myConfirm();" type="submit" name="deleteYear" class="btn btn-danger" value="Delete">

Javascript

<script>
function myConfirm() {
  var result = confirm("Want to delete?");
  if (result==true) {
   return true;
  } else {
   return false;
  }
}

改进user1697128(因为我还不能评论它)

<script>
    function ConfirmDelete()
    {
      return confirm("Are you sure you want to delete?");
    }
</script>    
    
<button Onclick="return ConfirmDelete();" type="submit" name="actiondelete" value="1"><img src="images/action_delete.png" alt="Delete"></button>

如果按“取消”键，会取消提交表格吗

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;
                        }

我知道这是老问题了，但我需要一个答案，这些答案都不是，但alpesh的答案对我有用，我想与可能有同样问题的人分享。

<script>    
function confirmDelete(url) {
    if (confirm("Are you sure you want to delete this?")) {
        window.open(url);
    } else {
        false;
    }       
}
</script>

普通版:

<input type="button" name="delete" value="Delete" onClick="confirmDelete('delete.php?id=123&title=Hello')">

我的PHP版本:

$deleteUrl = "delete.php?id=" .$id. "&title=" .$title;
echo "<input type=\"button\" name=\"delete\" value=\"Delete\" onClick=\"confirmDelete('" .$deleteUrl. "')\"/>";

这可能不是公开的正确方式，但在一个私人网站上，这对我来说是有效的。：）
