如何在 JavaScript 中显示 SweetAlert

Question

如何在此 JavaScript 代码中显示 SweetAlert？

function removeReg(del_reg) {
  if (confirm("Are you sure you want to delete? \n the reg name : " + del_reg)) {
    // Code goes here
  }
}

我只想在 if 条件下调用 SweetAlert，即在 SweetAlert 中，我需要显示消息 "Are you sure you want to delete?"。

调用swal()返回的swal() with your custom options in the removeReg(del_reg) function and use the Promise判断用户的选择：

如果用户点击YES，返回的value将是true
如果用户单击 NO 或按下 Esc 键，返回的 value 将是 null

var button = document.getElementById('remBtn')

function removeReg(del_reg) {
  swal({
      text: "Are you sure you want to delete? \n the reg name : " + del_reg,
      icon: "error",
      buttons: ['NO', 'YES'],
      dangerMode: true
    })
    .then(function(value) {
      console.log('returned value:', value);
    });
}

button.addEventListener('click', function() {
  console.log('clicked on button')
  removeReg('SomeCustomRegName');
});

<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script>
<button id="remBtn">Remove Registered Name</button>
