Write a TypeScript program that generates a randomized password comprising of alpha-numeric values and special characters. The password must be a minimum of 8 characters long and should contain at least one uppercase letter, one lowercase letter, one number, and one special character. The program should take input from the user for the length of the password and generate a new password every time the program is run. Finally, the program must display the generated password on the console or in the HTML document.

Sure, I can help you with that. Here's a TypeScript program that generates a randomized password. It's written in JavaScript but should work with TypeScript.

**HTML Document**

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Password Generator</title>
</head>
<body>
    <h1>Password Generator</h1>
    <label for="length">Password Length:</label>
    <input type="number" id="length" min="8" max="16">
    <button onclick="generatePassword()">Generate Password</button><br><br>
    <div id="password"></div>
    <script src="password.js"></script>
</body>
</html>
```

**JavaScript File**

```javascript
function generatePassword() {
  const length = parseInt(document.getElementById('length').value);
  const passwordRegex = /[a-z][A-Z][0-9][^a-zA-Z0-9]/{};
  let password = '';

  for (let I = 0; I < length; i++) {
    if (passwordRegex.test(password)) {
      break;
    }

    const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()_+-=?/';
    password += characters.charAt(Math.floor(Math.random() * characters.length));
  }

  const passwordElement = document.getElementById('password');
  passwordElement.innerHTML = `Your Password is: ${password}`;
}

generatePassword();
```

The above program generates a random password of length `length`, which is added as a parameter to the `generatePassword` function. It contains at least one uppercase letter, one lowercase letter, one number and one special character.

If you use this in TypeScript, add a `.ts` extension to `password.js`, and compile using a TypeScript compiler like `tsc`. Afterward, open the compiled JavaScript file generated by the TypeScript compiler.

Here's a TypeScript program that generates a randomized password based on the given criteria and displays it in an HTML document. Save this code in a file named `password-generator.ts`, and then compile it using the TypeScript compiler (tsc) to generate the corresponding JavaScript file (`password-generator.js`).

```html
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Password Generator</title>
    <script src="password-generator.js"></script>
</head>
<body>
    <h1>Password Generator</h1>
    <label for="passwordLength">Password Length:</label>
    <input type="number" id="passwordLength" min="8" value="8">
    <button onclick="generatePassword()">Generate Password</button>
    <p id="generatedPassword"></p>
</body>
</html>
```

```typescript
// password-generator.ts

const lowerCaseLetters = 'abcdefghijklmnopqrstuvwxyz';
const upperCaseLetters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
const numbers = '0123456789';
const specialCharacters = '!@#$%^&*()-_=+';

function generatePassword(length: number): string {
  if (length < 8) {
    throw new Error('Password must be at least 8 characters long');
  }

  const passwordCharacters = lowerCaseLetters + upperCaseLetters + numbers + specialCharacters;
  let password = '';

  // Ensure at least one character from each required group is included in the password
  password += lowerCaseLetters.charAt(Math.floor(Math.random() * lowerCaseLetters.length));
  password += upperCaseLetters.charAt(Math.floor(Math.random() * upperCaseLetters.length));
  password += numbers.charAt(Math.floor(Math.random() * numbers.length));
  password += specialCharacters.charAt(Math.floor(Math.random() * specialCharacters.length));

  // Fill the remaining length of the password with random characters from all groups
  for (let i = 4; i < length; i++) {
    password += passwordCharacters.charAt(Math.floor(Math.random() * passwordCharacters.length));
  }

  // Shuffle the password characters to ensure randomness
  password = password.split('').sort(() => Math.random() - 0.5).join('');

  return password;
}

function displayGeneratedPassword(password: string) {
  const passwordElement = document.getElementById('generatedPassword');
  if (passwordElement) {
    passwordElement.innerText = password;
  }
}

function generatePasswordAndDisplay() {
  const inputElement = document.getElementById('passwordLength') as HTMLInputElement;
  const passwordLength = parseInt(inputElement.value);

  try {
    const password = generatePassword(passwordLength);
    displayGeneratedPassword(password);
  } catch (error) {
    console.error(error.message);
  }
}

window.generatePassword = generatePasswordAndDisplay;
```

After compiling the TypeScript code, open the `index.html` file in your browser to see the password generator program. The generated password will be displayed on the HTML page when you click the "Generate Password" button.
