php - 如何将当前选项标记为选中？

Question

我有这样的页面

index.php?key=toplist&list=magic

例如，如果在该页面上，我希望在选择菜单中将 Magic 选项标记为选中

<select name="skill" onchange="window.location.href=this.form.skill.options[this.form.skill.selectedIndex].value">
<option value="index.php?<?=QUERY_STRING?>&list=experience">Experience&nbsp;</option>
<option value="index.php?<?=QUERY_STRING?>&list=magic">Magic</option>
<option value="index.php?<?=QUERY_STRING?>&list=shielding">Shielding</option>
<option value="index.php?<?=QUERY_STRING?>&list=distance">Distance</option>
<option value="index.php?<?=QUERY_STRING?>&list=fishing">Fishing</option>
</select>

谢谢

您将 selected 属性添加到 option 标记。我通常用这样的方式来做:

$lists = array('experience', 'magic', 'shielding', 'distance', 'fishing');
foreach($lists as $list)
    echo "<option value=\"index.php?$QUERY_STRING&list=$list\"" . ($list == $_GET['list'] ? " selected" : "") . ">" . ucfirst($list) . "</option>"
