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?"。

在removeReg(del_reg)函数中调用swal() with your custom options，然后使用swal()返回的Promise来确定用户的选择：

• 如果用户单击YES，则返回的value将是true
• 如果用户单击NO或按 Esc 键，则返回的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>
