How to concatenate string and javascript variable inside jquery selector

Question

How do I concatenate a string with a javascript variable inside a jquery selector? If I execute the code below. All the other form elements gets hidden.

var inputatr = $('input[type=text]').attr(); //button
$('input[value=string ' +  inputatr +']').hide(); //textbox

Update

<?php for($x=0; $x<4; $x++){ ?>

<input type="text" id="<?php echo $x; ?>" name="<?php echo $x; ?>" value="text<?php echo $x; ?>"/>
<input type="button" name="show<?php echo $x; ?>" value="string<?php echo $x; ?>"/></li>

<?php } ?>

Answer 1

$('input[value="string' + inputatr +'"]').hide();

This hides the input with the value equal to inputatr
