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 } ?>

What do you want the result to be? I don't what you get when you don't pass a parameter to attr. Check what inputatr contains. String concatenation works this way, but make sure you produce the right string. Please post your HTML. – Felix Kling May 6 '11 at 13:03
@Felix Kling: I have updated my question, please see it,thanks – user225269 May 6 '11 at 13:11
@user225269 I think what you're trying to accomplish is actually contrary what you have actually posted. If my presumption is correct, you're trying to make the textbox hide when the user clicks the corresponding button. is that correct? – Jim Rubenstein May 6 '11 at 13:20
Provide us an exemple of the desired result please. – Timon.Z May 6 '11 at 13:21

Are you trying to locate all your textboxes and hide the one with the value of 'string'? If so, the way to do that is actually something more like this:

$('input[type=text]').filter('input[value=string]').hide()

Updated because of your update:

$('input[type=button]').click(function(event)
{
    var strNum = $(this).val('name').replace('string', '');

    $('#' + strNum).hide();
}

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

This hides the input with the value equal to inputatr

I have a string value before the the value attribute of the textbox: <input type="text" value="string<?php $id; ?>"/> – user225269 May 6 '11 at 13:04
@user adjusted. – Raynos May 6 '11 at 13:11
his text input values are text+number, and all his buttons are named string+number - this wont select any textbox when he clicks the button. – Jim Rubenstein May 6 '11 at 13:19
