radio(单选框)
radio用于单选的情况
DOM结构
<div class="mui-input-row mui-radio">
<label>radio</label>
<input name="radio1" type="radio">
</div>
默认radio在右侧显示,若希望在左侧显示,只需增加.mui-left
类即可,如下:
<div class="mui-input-row mui-radio mui-left">
<label>radio</label>
<input name="radio1" type="radio">
</div>
若要禁用radio,只需在radio上增加disabled属性即可;
mui基于列表控件,提供了列表式单选实现;在列表根节点上增加.mui-table-view-radio
类即可,若要默认选中某项,只需要在对应li
节点上增加.mui-selected
类即可,dom结构如下:
<ul class="mui-table-view mui-table-view-radio">
<li class="mui-table-view-cell">
<a class="mui-navigate-right">Item 1</a>
</li>
<li class="mui-table-view-cell mui-selected">
<a class="mui-navigate-right">Item 2</a>
</li>
<li class="mui-table-view-cell">
<a class="mui-navigate-right">Item 3</a>
</li>
</ul>
列表式单选在切换选中项时会触发selected事件,在事件参数(e.detail.el
)中可以获得当前选中的dom节点,如下代码打印当前选中项的innerHTML:
var list = document.querySelector('.mui-table-view.mui-table-view-radio');
list.addEventListener('selected',function(e){
console.log("当前选中的为:"+e.detail.el.innerText);
});
