You can use this which refers to the current input element.

$('input[type=radio][name=bedStatus]').change(function() {
    if (this.value == 'allot') {
        // ...
    }
    else if (this.value == 'transfer') {
        // ...
    }
});

Note that you are comparing the value against allot in both if statements and :radio selector is deprecated.

In case that you are not using jQuery, you can use the document.querySelectorAll and HTMLElement.addEventListener methods:

var radios = document.querySelectorAll('input[type=radio][name="bedStatus"]');

function changeHandler(event) {
   if ( this.value === 'allot' ) {
     console.log('value', 'allot');
   } else if ( this.value === 'transfer' ) {
      console.log('value', 'transfer');
   }  
}

Array.prototype.forEach.call(radios, function(radio) {
   radio.addEventListener('change', changeHandler);
});

 }
   
<input type="radio" name="bedStatus" value="allot" onchange="my_function('allot')" checked="checked">Allot

Add the class "pnradio" to the radio buttons, then switch with .attr('id')

<input type="radio" id="sampleradio1" class="pnradio" />
<input type="radio" id="sampleradio2" class="pnradio" />
    $('.pnradio').click(function() {
          switch ($(this).attr('id')) {
            case 'sampleradio1':
              alert("xxx");
              break;
            case 'sampleradio2':
              alert("xxx");
              break;
          }
        });

Simple ES6 (javascript only) solution.

document.forms.demo.bedStatus.forEach(radio => {
  radio.addEventListener('change', () => {
    alert(`${document.forms.demo.bedStatus.value} Thai Gayo`);
  })
});
<form name="demo">
  <input type="radio" name="bedStatus" value="Allot" checked>Allot
  <input type="radio" name="bedStatus" value="Transfer">Transfer
</form>

$(document).ready(function () {
    $('input:radio[name=bedStatus]:checked').change(function () {
        if ($("input:radio[name='bedStatus']:checked").val() == 'allot') {
            alert("Allot Thai Gayo Bhai");
        }
        if ($("input:radio[name='bedStatus']:checked").val() == 'transfer') {
            alert("Transfer Thai Gayo");
        }

An adaptation of the above answer...

$('input[type=radio][name=bedStatus]').on('change', function() {
  switch ($(this).val()) {
    case 'allot':
      alert("Allot Thai Gayo Bhai");
      break;
    case 'transfer':
      alert("Transfer Thai Gayo");
      break;
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="radio" name="bedStatus" id="allot" checked="checked" value="allot">Allot
<input type="radio" name="bedStatus" id="transfer" value="transfer">Transfer

If the radio buttons are added dynamically, you may wish to use this

$(document).on('change', 'input[type=radio][name=bedStatus]', function (event) {
    switch($(this).val()) {
      case 'allot' :
        alert("Allot Thai Gayo Bhai");
        break;
      case 'transfer' :
        alert("Transfer Thai Gayo");
        break;
    }     
});

document.addEventListener('DOMContentLoaded', () => {
  const els = document.querySelectorAll('[name="bedStatus"]');

  const capitalize = (str) =>
    `${str.charAt(0).toUpperCase()}${str.slice(1)}`;

  const handler = (e) => alert(
    `${capitalize(e.target.value)} Thai Gayo${e.target.value === 'allot' ? ' Bhai' : ''}`
  );

  els.forEach((el) => {
    el.addEventListener('change', handler);
  });
});

A simpler and cleaner way would be to use a class with @Ohgodwhy's answer

<input ... class="rButton">
<input ... class="rButton">

Script

​$( ".rButton" ).change(function() {
    switch($(this).val()) {
        case 'allot' :
            alert("Allot Thai Gayo Bhai");
            break;
        case 'transfer' :
            alert("Transfer Thai Gayo");
            break;
    }            
});​

$(document).ready(function () {
    $('#allot').click(function () {
        if ($(this).is(':checked')) {
            alert("Allot Thai Gayo Bhai");
        }
    });

    $('#transfer').click(function () {
        if ($(this).is(':checked')) {
            alert("Transfer Thai Gayo");
        }
    });
});
