mui的input搜索框里的清除按钮的点击监听事件

<div class="mui-search-padding " style="padding-bottom: 3px;">
    <div class="mui-indexed-list-search mui-input-row mui-search">
        <input id="searchIpt"  oninput="search(0)" onporpertychange="search(0)" type="search" class="mui-input-clear mui-indexed-list-search-input" placeholder="搜索">
        </div>
</div>

清除按钮的点击监听：

mui(".mui-input-clear")[0].addEventListener('focus', function(){
    mui(".mui-icon-clear")[0].addEventListener('tap',function(){
        search(0);
    });
})

因为MUI搜索框里自带的清除按钮是当input框focus，即input获取焦点的时候才出现的，如果不要input的focus监听事件，那么清除按钮的点击事件是不会监听到的
