js循环生成div div里面有p标签 点击事件怎么得到点击的p标签内的值

<script id="dataTemplate" type="text/html">
    {{# for(var i=0;i<useData.length;i++){ }} 
        <div class="weui-cell" onclick="details(this);>
        <div class="weui-cell__bd">
            <label>{{ useData[i].DATE_TIME }}</label>
        </div>
        <div class="weui-cell__ft">
            <p>{{ useData[i].DATA }} kWh</p>
        </div>
        </div>
    {{# }}}
</script>`
