<p>You can use <code>this</code> which refers to the current <code>input</code> element.</p>

<pre><code>$('input[type=radio][name=bedStatus]').change(function() {
    if (this.value == 'allot') {
        alert("Allot Thai Gayo Bhai");
    }
    else if (this.value == 'transfer') {
        alert("Transfer Thai Gayo");
    }
});
</code></pre>

<p><a href="http://jsfiddle.net/4gZAT/" rel="noreferrer">http://jsfiddle.net/4gZAT/</a></p>

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

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

<pre><code>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);
});
