如果看不到实际的源，我猜字段标签会干扰字段。将鼠标放在字段上将使其聚焦，但将鼠标放在标签上将使标签的关联字段聚焦。

这件事曾经发生在我身上，所以我希望当我对不同的输入字段使用相同的ID时，我能做到这一点。。。

尝试检查输入字段中是否存在重复的ID。

<input type="" id="numberone" />
<input type="" id="numbertwo" />
<input type="" id="numberthree" />

Or in the case of meta boxes  
(example from some meta boxes i created)  

array(
\'name\' => __(\'Usage Instructions\', \'sagive\'),
\'desc\' => __(\'Please Insert all available data on this website to achive a great look for the business page\', \'sagive\'),
\'type\' => \'title\',
),
array(
    \'name\' => __(\'Website URL\', \'sagive\'),
    \'desc\' => __(\'(example: http://www.sagive.co.il)\', \'sagive\'),
    \'id\'   => $prefix . \'numberone\',
    \'type\' => \'numberthree\',
),  
array(
    \'name\'    => __(\'NoFollow Tag\', \'sagive\'),
    \'desc\'    => __(\'Would you like to use NoFollow for his website?\', \'sagive\'),
    \'id\'      => $prefix . \'numbertwo\',
    \'type\'    => \'radio\',
    \'options\' => array(
        array( \'name\' => __(\'Yes\', \'sagive\'), \'value\' => \'yes\', ),
        array( \'name\' => __(\'No\', \'sagive\'), \'value\' => \'no\', ),
    ),
),

向你问好，萨吉夫
