Assuming the following HTML as an example:
<div class="div">
<input type="text" />
<input type="text" />
<input type="text" />
</div>
<input type="text" class="b"/>
One can use the following script, using the focus and blur events:
$('.div input[type="text"]').on('focus', function(){
$('.b').prop('disabled', true);
}).on('blur', function(){
$('.b').prop('disabled', false);
});
