<p>比如说，搜索按钮的清空筛选条件，或者管理平台新增成功后给数据赋值为空,大量数据，挨个赋值比较麻烦,所以封装一个方法</p>
<p>点击下面的清空按钮：清空标题，改变结尾，内容不变,</p>
<div id="app">
<h1>
现在的标题： <span style="color:red;"> {{title}} </span>
</h1>
<p>
现在的内容: <span style="color:red;"> {{content}} </span>
</p>
<p>
测试的结尾: <span style="color:red;"> {{end}} </span>
</p>
<button @click="empty_btn()">清空</button>
</div>
