有时候我们在网页中填写某些表单时，可能会遇到单选按钮，如让你选择性别是男或是女，此时用户往往会去点击单选按钮那个小小的圆圈，由于单选按钮比较小，可能会点不到，所以最好是点击单选按钮后面的文字就能直接选中单选按钮，正如下图所示：
相关代码如下：

<body>
<form name="htmer" method="post" action="">
<input name="htmer_radio" id="htmer_radio1" type="radio" /><label for="htmer_radio1">HTMer.Com_选项1</label>
<input name="htmer_radio" id="htmer_radio2" type="radio" /><label for="htmer_radio2">HTMer.Com_选项2</label>
</form>

<body>
<form name="htmer" method="post" action="">
<input name="htmer_radio" id="htmer_radio1" type="radio" /><label for="htmer_radio1">HTMer.Com_选项1</label>
<input name="htmer_radio" id="htmer_radio2" type="radio" /><label for="htmer_radio2">HTMer.Com_选项2</label>
</form>
</body>
</html>
主要是label要指定for="htmer_radio1",htmer_radio1是对应单选框radio的id
