您可能使用的是SweetAlert version 2，并且您的代码适用于版本1。

swal({
  title: 'Are you sure?',
  text: 'Some text.',
  type: 'warning',
  showCancelButton: true,
  confirmButtonColor: '#DD6B55',
  confirmButtonText: 'Yes!',
  cancelButtonText: 'No.'
}).then(() => {
  if (result.value) {
    // handle Confirm button click
  } else {
    // result.dismiss can be 'cancel', 'overlay', 'esc' or 'timer'
  }
});

<script src="https://unpkg.com/sweetalert2@7.8.2/dist/sweetalert2.all.js"></script>

试试这个

$(document).ready(function () {
  $('body').on('click', 'td.warning input', function () {
    swal({
        title: "Are you sure?",
        text: "You will not be able to recover this imaginary file!",
        type: "warning",
        showCancelButton: true,
        confirmButtonClass: 'btn-danger',
        confirmButtonText: 'Yes, delete it!',
        cancelButtonText: "No, cancel plx!",
        closeOnConfirm: false,
        closeOnCancel: false
      },
      function (isConfirm) {
        if (isConfirm) {
          swal("Deleted!", "Your imaginary file has been deleted!", "success");
        } else {
          swal("Cancelled", "Your imaginary file is safe :)", "error");
        }
      });
  });
});

如果你想甜警报点击任何按钮，然后改变你的代码如下：

$(document).ready(function(){
  $(document).on('click', 'button', function(){
    Swal.fire({     
       type: 'success',
       title: 'Your work has been done',
       showConfirmButton: false,
       timer: 1500
    })
  });
});

使用sweetalert更容易，例如，我喜欢一个链接，我需要的是调用onclick函数，并确保我包括 sweetalser.css 和sweetalert.min.js，我希望这将为您工作

<a onclick="sweetAlert('Greetings', 'Hi', 'error');" class="" data-toggle="modal" href='#modale-id'><i class="fa fa-fw fa-plus"></i>Streams</a>

您只选择了与'td.warning input'选择器匹配的第一个元素，这就是为什么第二个元素不会发生任何变化。
尝试querySelectorAll('td.warning input')方法。该方法返回一个数组，您可以循环访问该数组以设置事件侦听器。

窗口.onload=函数（）
{

swal({   title: "PopOutTitle",   text: "Your FIRST Name:",   type: "input",   showCancelButton: true, OnConfirm:school();  
         animation: "slide-from-top",     inputPlaceholder: name }, function(inputValue){   if (inputValue === false) return false;
         if (inputValue === "") { swal.showInputError("You need to write something!"); return false } 
           document.getElementById("name").innerHTML=inputValue || "Unknown";

});

 }

功能学校（）{

swal({   title: "PopOutTitle",   text: "Your last Name:",   type: "input",   showCancelButton: true,   
         animation: "slide-from-top",     inputPlaceholder: name }, function(inputValue){   if (inputValue === false) return false;
         if (inputValue === "") { swal.showInputError("You need to write something!"); return false } 
           document.getElementById("name").innerHTML=inputValue || "Unknown";

});**I want to show multiple swal popout so I want to call the school function when Ok Button is clicked. How can I do this?**

<script>
$(document).ready(function(){
  $('.btn-danger').on("click", function(){
swal({
title: "Delete?",
text: "Please ensure and then confirm!",
type: "warning",
showCancelButton: !0,
confirmButtonText: "Yes, delete it!",
cancelButtonText: "No, cancel!",
reverseButtons: !0
}).then(function (e) {
if (e.value === true) {
    var CSRF_TOKEN = $('meta[name="csrf-token"]').attr('content');
    var id = $('.btn-danger').attr('data-id');
    var cur_row = this;
    $.ajax({
    type: 'POST',
    url: "{{url('/product_delete')}}/" + id,
    data: {_token: CSRF_TOKEN},
    dataType: 'JSON',
    success: function (results) {
    if (results.success === true)
    {
        swal("Done!", results.message, "success");
        setTimeout(function(){
                   location.reload()
                }, 2000);
    } 
    else
    {
        swal("Error!", results.message, "error");
    }
    }
    });
}
    });
  });
});
</script>
