从单选按钮滑块的纯css实现创建JS事件
Creating JS event from pure css implementation of radio button slider
我有以下纯html和css的无线电滑块实现。基于toggle函数创建javascript事件的好方法是什么?我可以看到一些方法来轮询组件并获得其位置,但是,我不确定如何获得更改以触发回调等。谢谢。

<div class="container">
<div class="switch">
<input type="radio" class="switch-input" name="view" value="week" id="week" checked>
<label for="week" class="switch-label switch-label-off">ON</label>
<input type="radio" class="switch-input" name="view" value="month" id="month">
<label for="month" class="switch-label switch-label-on">OFF</label>
<span class="switch-selection"></span>
</div>
</div>
您可以简单地使用
if (document.getElementById('week').checked) {
//task to perform when "ON"
}
else
{
//task to perform when "OFF"
}
