<div id="recommand_tags">
<ul>
<?php foreach($recommand_tags as $t => $tag) : ?>
<li><?=$tag->name?></li>
<?php endforeach; ?>
</ul>
</div>A feature where clicking a “recommended tag” inserts it into an input field.
Clicking a “recommended tag” below the input field inserts it into the UI,
but every click was adding an extra empty space.
In Internet Explorer 7, when reading event.target.innerHTML on the mouse click event, there was always a trailing space added.
<div id="recommand_tags"><ul><?php foreach($recommand_tags as $t => $tag) : ?><li><?=$tag->name?></li><?php endforeach; ?></ul></div>Writing it as a single line like this removes the empty space.
