--description--
提交表单时,所选项的值会发送给服务端。radio
和 checkbox
的 value
属性值决定了发送到服务端的实际内容。
例如:
<label for="indoor">
<input id="indoor" value="indoor" type="radio" name="indoor-outdoor">Indoor
</label>
<label for="outdoor">
<input id="outdoor" value="outdoor" type="radio" name="indoor-outdoor">Outdoor
</label>
这里有两个 radio
单选框。当用户提交表单时,如果 indoor
选项被选中,表单数据会包含:indoor-outdoor=indoor
。也就是所选项的 name
和 value
属性值。
如果没有指明 value
属性值,则会使用默认值做为表单数据提交,也就是 on
。在这种情况下,如果用户选中 "indoor" 选项然后提交表单,表单数据则会包含 indoor-outdoor=on
。这样的表单数据看起来不够直观,因此最好将 value
属性值设置为一些有意义的内容。
--instructions--
给每一个 radio
和 checkbox
输入框添加 value
属性,属性值为 input
对应 label
中文本的小写形式。如 Outdoor 的 value
应设置为 "outdoor"
,即 value="outdoor"
。
--hints--
应有一个单选按钮的 value
属性值为 indoor
。
assert(
$('label:contains("Indoor") > input[type="radio"]').filter("[value='indoor']")
.length > 0
);
应有一个单选按钮的 value
属性值为 outdoor
。
assert(
$('label:contains("Outdoor") > input[type="radio"]').filter(
"[value='outdoor']"
).length > 0
);
应有一个复选框的 value
属性值为 loving
。
assert(
$('label:contains("Loving") > input[type="checkbox"]').filter(
"[value='loving']"
).length > 0
);
应有一个复选框的 value
属性值为 lazy
。
assert(
$('label:contains("Lazy") > input[type="checkbox"]').filter("[value='lazy']")
.length > 0
);
应有一个复选框的 value
属性值为 energetic
。
assert(
$('label:contains("Energetic") > input[type="checkbox"]').filter(
"[value='energetic']"
).length > 0
);
