Toggle HTML radio button by clicking its label
提问by Alexander Farber
Is there please a simple way to make a radio button toggle - when a text near it is clicked - without introducing any big Javascript Framework into my smal PHP project?
是否有一种简单的方法可以使单选按钮切换 - 当单击它附近的文本时 - 而不会在我的小型 PHP 项目中引入任何大型 Javascript 框架？
The web form looks like this:
Web 表单如下所示：
<html>
<body>
<form method="post">
<p>Mode:<br />
<input type="radio" name="mode" value="create"><i>create table</i><br />
<input type="radio" name="mode" value="select" checked>select records (can specify id)<br />
<input type="radio" name="mode" value="insert">insert 1 record (must specify all)<br />
<input type="radio" name="mode" value="delete">delete records (must specify id)<br />
<input type="radio" name="mode" value="drop"><i>drop table</i><br />
</p>
<p>Id: <input type="text" name="id" size=32 maxlength=32 /> (32 hex chars)</p>
<p>Latitude: <input type="text" name="lat" size=10 /> (between -90 and 90)</p>
<p>Longitude: <input type="text" name="lng" size=10 /> (between -90 and 90)</p>
<p>Speed: <input type="text" name="spd" size=10 /> (not negative)</p>
<p><input type="submit" value="OK" /></p>
</form>
</body>
</html>

You can also wrap your elements withoutgiving them each an ID, since a <label>is implicitly for the input it contains, like this:
您还可以包装您的元素而不给它们每个 ID，因为 a<label>隐式表示它包含的输入，如下所示：
<label>
<input type="radio" name="mode" value="create">
<i>create table</i>
</label>

Wrapping the input under the label should work.
将输入包装在标签下应该有效。
<label>
<input type="radio" name="mode" value="create"><i>create table</i>
</label>

I had trouble finding the value of the radio button using this method, an alternative is to use a hit area increasing clickable area of a button.
我无法使用此方法找到单选按钮的值，另一种方法是使用增加按钮的可点击区域的点击区域。
