<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

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>

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

使用jQuery:

$(".delete-link").on("click", null, function(){
        return confirm("Are you sure?");
    });

Angularjs与Javascript删除示例

html代码

<button ng-click="ConfirmDelete(single_play.play_id)" type="submit" name="actiondelete" value="1"><img src="images/remove.png" alt="Delete"></button>

“single_play。Play_id "是任意angularjs变量，假设你想在删除操作期间传递任何参数

app模块内的Angularjs代码

$scope.ConfirmDelete = function(yy)
        {
            var x = confirm("Are you sure you want to delete?");
            if (x) {
             // Action for press ok
                $http({
                method : 'POST',
                url : 'sample.php',
                headers: {'Content-Type': 'application/x-www-form-urlencoded'},
                data: $.param({ delete_play_id : yy})
                }).then(function (response) { 
                $scope.message = response.data;
                });
            }
            else {
             //Action for cancel
                return false;
            }
        } 

您可以更好地使用以下方法

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>
