I am trying to populate a dropdown option for a SweetAlert alert by passing an array or string list from my MVC controller to view.

I can get the values to populate in the dropdown but when the text is selected it only returns the value such as 0 and will not return the text. Which is meaningless.

I have tried passing it in a two-dimensional array so I was setting the value and text but that didn't display right. I have also tried passing a directory but I was not able to get that to parse in my Jquery.

Sorry if this is something very obvious

What I have tried:

var inputOptionsPromise = obj.Attatchments;
            title: 'Select Attatchment for Upload',
            input: 'select',
            inputOptions: inputOptionsPromise,
            inputPlaceholder: 'Select an attatchment',
            showCancelButton: true,
            inputValidator: (value) => {
            return new Promise(function (resolve, reject) {
              if (value !== '') {
              } else {
                resolve('Select an attatchment');
        }).then(function (result) {
          if (result.isConfirmed) {
// trying to get text value


string[,] array2D = new string[,] { { "text.pdf","text.pdf"}, { "test.txt", "test.txt" } };
                                //string[] array = new string[] { "text.pdf", "test.txt" };

return Json(JsonConvert.SerializeObject(new { Success = false, File = fileStream, Attatchments = array2D , ErrorMessage = "" }), JsonRequestBehavior.AllowGet);

SweetAlert2 gives you a working code example that shows you how: SweetAlert2 - a beautiful, responsive, customizable and accessible (WAI-ARIA) replacement for JavaScript's popup boxes[^] - look at the Select (as per their example):
const { value: fruit } = await{
  title: 'Select field validation',
  input: 'select',
  inputOptions: {
    'Fruits': {
      apples: 'Apples',
      bananas: 'Bananas',
      grapes: 'Grapes',
      oranges: 'Oranges'
    'Vegetables': {
      potato: 'Potato',
      broccoli: 'Broccoli',
      carrot: 'Carrot'
    'icecream': 'Ice cream'
  inputPlaceholder: 'Select a fruit',
  showCancelButton: true,
  inputValidator: (value) => {
    return new Promise((resolve) => {
      if (value === 'oranges') {
      } else {
        resolve('You need to select oranges :)')

if (fruit) {`You selected: ${fruit}`)

Hi Graeme

I have tried this solution but it returns oranges and not Oranges.
So in my case when i am passing the inputs it will be something like inputOptions: { 0: "File1.pdf", 1: "File2.pdf"}

When the user is selecting the option from the drop-down it then returns 0 not "File1.pdf". So i need to either be able to pass inputOptions: { "File1.pdf": "File1.pdf", "File2.pdf": "File2.pdf"} from the controller or select the text value from the drop down

If you use the browser developer tools and look at the html generated by the lib you can see what is happening:
HTMLCopy Code
<option value="oranges">Oranges</option>

As you can see above, SA2 will return oranges when the user selects Oranges. value="oranges" is the return type.
