"request" keyword is added multiple times

[SergeyBiryukov]

On the ​Polyglots blog, if you click "request" several times in a row, the keyword is appended multiple times, which looks weird (see the screenshot).

This is the click handler:

$('.p2-request-tag').click( function() {
	var tags = $('#tags'), val = tags.val();
	if ( val === 'Tag it' )
		tags.val( 'request, ');
	else
		tags.val( 'request, ' + val );
});

I don't see it anywhere in the open sourced code, but this should fix it:

$('.p2-request-tag').click( function() {
	var tags = $('#tags'), val = tags.val();
	if ( val === 'Tag it' )
		tags.val( 'request, ');
	else if ( 'request,' != val.substr( 0, 8 ) )
		tags.val( 'request, ' + val );
});

Fixed.

I opted to use val.indexOf( 'request' ) < 0 instead of 'request,' != val.substr( 0, 8 ) as the conditional check before adding 'request' into the tags field so that if the tag appears anywhere (instead of just the beginning) then it won't be added via the helper link.
