如何在 JavaScript 中显示 SweetAlert

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
  }
}

我只想在中调用 SweetAlertif条件，即在 SweetAlert 中，我需要显示消息"Are you sure you want to delete?".

Call swal()与您的自定义选项 https://sweetalert.js.org/guides/#using-options in the removeReg(del_reg)功能并使用Promise https://sweetalert.js.org/guides/#using-promises由返回swal()确定用户的选择：

• 如果用户点击了YES，返回的value将true
• If the user clicked NO or pressed the Esc key, the returned value will be 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>
