今天使用微信的WEUI的checkbox的时候，发现点击checkbox是有checked和unchecked的变化的，但是想要去获得checkbox的checked状态时，发现event listener里居然没有该checkbox的click之类的事件。
先看看html代码
<div class="weui-cells weui-cells_checkbox">
<label class="weui-cell weui-check__label" for="s11">
<div class="weui-cell__hd">
<input type="checkbox" class="weui-check" name="checkbox1" id="s11" checked="checked">
<i class="weui-icon-checked"></i>
</div>
<div class="weui-cell__bd">
<p>standard is dealt for u.</p>
</div>
</label>
</div>
看看weui里checkbox的css是如何写的
.weui-cells_checkbox .weui-icon-checked:before{
content:'\EA01';
color:#c9c9c9;
font-size:23px;
display:block;
}
.weui-cells_checkbox .weui-check:checked + .weui-icon-checked:before{
content:'\EA06';
color:#09BB07;
}
css选择器中‘+‘代表什么？
css中:checked‘是什么意思？
content对应的值是啥？
.weui-cells_checkbox .weui-icon-checked:before{
content:'\EA01';
color:#c9c9c9;
font-size:23px;
display:block;
}
.weui-cells_checkbox .weui-check:checked + .weui-icon-checked:before{
content:'\EA06';
color:#09BB07;
}
