问题出现的原因：输入框绑定值改变导致代码从新渲染
<div v-for="(x,index) in item.newAttrs " :key="x.en" class="attr_row">
<div class="attr_cell flex">
<el-input size="mini" v-model="x.en"></el-input>
</div>
</div>
修改后:将key值改为和输入框不同的值
<div v-for="(x,index) in item.newAttrs " :key="index" class="attr_row">
<div class="attr_cell flex">
<el-input size="mini" v-model="x.en"></el-input>
</div>
</div>
